  1. Characterization of CERN-EU high energy reference radiation fields with recombination chamber

    Golnik, N.

    1998-01-01

    The CERN-EU reference radiation field facility (called CERFF) is available behind a shielding of high-energy particles beam at CERN since 1993. At present the parameters of the radiation from beam target are well investigated, however, there are still some serious doubts concerning contribution of low-LET concurrent radiation. This paper presents an experimental procedure for determination of the contribution from the concurrent radiation by measuring the absorbed dose and recombination index of radiation quality at different beam intensities. Additionally, the values of H * (10) were measured in several measuring locations. Measurements were performed with a REM-2 recombination chamber and compared with those obtained by using a HANDI-TEPC instrument. (author)

    The CERN-EU high-energy reference field facility is used for testing and calibrating both active and passive radiation dosemeters for radiation protection applications in space and aviation. Through a combination of a primary particle beam, target and a suitable designed shielding configuration, the facility is able to reproduce the neutron component of the high altitude radiation field relevant to the jet aviation industry. Simulations of the facility using the GEANT4 (GEometry ANd Tracking) toolkit provide an improved understanding of the neutron particle fluence as well as the particle fluence of other radiation components present. The secondary particle fluence as a function of the primary particle fluence incident on the target and the associated dose equivalent rates were determined at the 20 designated irradiation positions available at the facility. Comparisons of the simulated results with previously published simulations obtained using the FLUKA Monte Carlo code, as well as with experimental results of the neutron fluence obtained with a Bonner sphere spectrometer, are made.

    In July 2009 the European Commission (EC) finalised how it will spend research funding for 2010, within its Framework Programme 7 (FP7). On 31 July the EC is expected to publish new calls for European project proposals, many of which are relevant to CERN. In the first two and a half years of Framework Programme 7 (2007-2013), CERN has been very successful – the Organization is participating in around 30 EU projects, with total EC contribution of nearly 35 million Euros. The now finalised 2010 Work Programmes for FP7 outline how the EC will allocate budgets within each research field. From these Work Programmes, a series of calls for proposals are published so researchers can apply for targeted funding within given deadlines. The first calls are expected to be launched on 31 July and closed later in the year. The web-site of the CERN EU Projects Office contains a list of all new calls of potential interest to CERN, as well as the relevant Work Programmes and Guide for A...

    2014-01-01

    This paper discusses an intercomparison campaign performed in the mixed radiation field at the CERN-EU (CERF) reference field facility. Various instruments were employed: conventional and extended-range rem counters including a novel instrument called LUPIN, a bubble detector using an active counting system (ABC 1260) and two tissue-equivalent proportional counters (TEPCs). The results show that the extended range instruments agree well within their uncertainties and within 1σ with the H*(10) FLUKA value. The conventional rem counters are in good agreement within their uncertainties and underestimate H*(10) as measured by the extended range instruments and as predicted by FLUKA. The TEPCs slightly overestimate the FLUKA value but they are anyhow consistent with it when taking the comparatively large total uncertainties into account, and indicate that the non-neutron part of the stray field accounts for ∼30 % of the total H*(10).

    Without fanfare, 600 Russian scientists here at CERN, the European particle physics laboratory, are playing key roles in building the Large Hadron Collider (LHC), a machine that will explore fundamental questions such as why particles have mass, as well as search for exotic new particles whose existence would confirm supersymmetry, a popular theory that aims to unify the four forces of nature. In fact, even though Russia is not one of CERN's 20 member states, most top high-energy physicists in Russia are working on the LHC. Some say their work could prove the salvation of high-energy physics back home.

    A reference facility for the calibration and intercomparison of active and passive detectors in broad neutron fields has been available at CERN since 1992. A positively charged hadron beam (a mixture of protons and pions) with momentum of 120 GeV/c hits a copper target, 50 cm thick and 7 cut in diameter. The secondary particles produced in the interaction traverse a shield, at 90 degrees with respect to the direction of the incoming beam, made of either 80 to 160 cm of concrete or 40 cm of iron. Behind the iron shield, the resulting neutron spectrum has a maximum at about 1 MeV, with an additional high-energy component. Behind the 80 cm concrete shield, the neutron spectrum has a second pronounced maximum at about 70 MeV and resembles the high-energy component of the radiation field created by cosmic rays at commercial flight altitudes.

    2006-01-01

    The Large Hadron Collider (LHC) at CERN (The European Organisation for Nuclear Research) is one of the largest and most complicated machines envisaged to date. The LHC has been conceived and designed over the course of the last 25 years and represents the cutting edge of accelerator technology with a collision energy of 14TeV, having a stored beam energy over 100 times more powerful than the nearest competitor. Commissioning of the machine is already nderway and operation with beam is intended for Autumn 2007, with 7TeV operation expected in 2008. The LHC is set to answer some of the fundemental questions in theoretical physics, colliding particles with such high energy that the inner workings of the quantum world can be revealed. Colliding particles together at such high energy makes very high demands on machine operation and protection. The specified beam energy requires strong magnetic fields that are made in superconducting dipole magnets, these magnets are kept only around two degrees above absolute zero...

    One year ago, with the world catalogue of Z particles - the electrically neutral carrier of the weak nuclear force - containing a few hundred examples, it sounded extravagant when proponents of CERN's new LEP electron-positron collider promised a hundred thousand Zs by Christmas 1989. The first round of experiments in the North Area of CERN's SPS proton synchrotron included a considerable investment in studies using high energy muon beams. This paid off with important contribuions to physics, particularly in the measurement of the quark/gluon content (structure functions) of nucleons. ; The LEAR low energy antiproton ring at CERN takes its antimatter beams down to very low kinetic energies - less than 10 MeV - for a unique range of physics studies. However even these modest energies are too high for a series of experiments aiming to explore the effects of gravity on antimatter.

    Europe is facing a future of augmenting energy demands, domestic depletion, high prices and other energy-political challenges. Climate change, infrastructure resilience, producers' coercive energy policy and the EU's internal market failures have put stress on the EU's emerging energy policy and inspired the union to address its challenges with greater enthusiasm than before. Some of the EU's challenges call for strategic choices of a magnitude that EU is not used to handle. The aim of this report is therefore to identify, analyse and assess the political side of Europe's energy predicament and import dependency. Against the background of increasing dependence on energy imports, the report tries to answer questions: what are the key dimensions of Europe's energy security and what are their consequences?

The first round of experiments in the North Area of CERN's SPS proton synchrotron included a considerable investment in studies using high energy muon beams. This paid off with important contribuions to physics, particularly in the measurement of the quark/gluon content (structure functions) of nucleons. ; The LEAR low energy antiproton ring at CERN takes its antimatter beams down to very low kinetic energies - less than 10 MeV - for a unique range of physics studies. However even these modest energies are too high for a series of experiments aiming to explore the effects of gravity on antimatter

  16. Tackling Dependency: The EU and its Energy Security Challenges

    2007-10-15

    Europe is facing a future of augmenting energy demands, domestic depletion, high prices and other energy-political challenges. Climate change, infrastructure resilience, producers' coercive energy policy and the EU's internal market failures have put stress on the EU's emerging energy policy and inspired the union to address its challenges with greater enthusiasm than before. Some of the EU's challenges call for strategic choices of a magnitude that EU is not used to handle. The aim of this report is therefore to identify, analyse and assess the political side of Europe's energy predicament and import dependency. Against the background of increasing dependence on energy imports, the report tries to answer questions: what are the key dimensions of Europe's energy security and what are their consequences?

    Information searchers from the high energy physics community expect an integrated information environment. The CERN Library offers its print and electronic collections through a combined Web interface and maintains the database by semi-automated processes to upload bibliographic and full-text records. Suggestions are offered by which INIS could develop its own Web interface and better match HEP users’ expectations. These include implementing full-text linking, increasing currency, expanding search and display functions and developing the richness of the data. Links with the National Nuclear Data Center and Crossref could also increase its visibility.

    Full text: A world-wide effort is under way to develop linear electron-positron colliders so that physics experiments can be extended into a range of energies where circular machines (necessarily much larger than CERN's 27-kilometre LEP machine) would be crippled by synchrotron radiation. CERN is studying the feasibility of building a 2 TeV machine called CLIC powered not by individual klystrons, but by a high intensity electron 'drive' linac running parallel to the main linac (November 1990, page 7). This drive linac will itself be powered by similar superconducting cavities to those developed for LEP. A high gradient is an obvious design aim for any future high energy linear collider because it makes it shorter and therefore cheaper - the design figure for the CLIC machine is 80 MV/m. The CLIC study group has taken a significant step forward in demonstrating the technical feasibility of their machine by achieving peak and average accelerating gradients of 137 MV/m and 84 MV/m respectively in a short section of accelerating structure during high gradient tests at the Japanese KEK Laboratory last year. This result obtained within the framework of a CERN/KEK collaboration on linear colliders was obtained using a 20-cell accelerating section built at CERN using state-of the- art technology which served both as a model for CLIC studies as well as a prototype for the Japanese Linear Collider studies. The operating frequency of the model accelerating section is 2.6 times lower than the CLIC frequency but was chosen because a high power r.f. source and pulse compression scheme has been developed for this frequency at KEK. Testing CLIC models at 11.4 GHz is however more stringent than at 30 GHz because the chance of electrical breakdown increases as the frequency is lowered. This recent result clearly demonstrates that a gradient of 80 MV/m is feasible.

  1. Enlarging the EU's internal energy market: Why would third countries accept EU rule export?

    2009-01-01

    Why would countries without a membership perspective seek integration into the EU's internal energy market? One major element of the EU's external energy policy is the export of EU energy norms and regulations to neighbourhood countries and beyond. A core legal instrument the EU uses in this context is the Energy Community Treaty (ECT). The ECT goes both geographically and regarding its depth significantly beyond neighbourhood or association policies, addressing potentially also countries in the 'far neighbourhood' and aiming at the creation of a Single Market for energy with these countries. While, however, EU candidate countries are obliged to adopt the 'acquis' before accessing the EU and therefore comply to EU rules already before they enter the Club, I argue that countries with no or only a vague membership perspective - i.e. countries where the EU cannot apply the 'conditionality' - approach (e.g., ENP countries)-aim at deeper integration with the EU because they are either eager to demonstrate their capability and potential to become part of the Club, they seek greater independence from a regional hegemon or they envisage significant economic gains as common norms, rules and standards are likely to increase economic exchange with the EU.

    High energy stray radiation fields have been realised since 1993 at CERN also in the frame of CEC-CERN collaboration on the project: 'Detection and the Dosimetry of Neutrons and Charged Particles at Aviation Altitudes in the Earth's Atmosphere'. They are formed at the H6 beam of the north experimental area of the SPS facility. Two shielding configurations have been built, with the top concrete, resp. top iron shielding. Many intercalibration experiments have been realised since the beginning. After an interruption due to technical problems, two other campaigns have been realised during 2006 year, another one during the June 2007. This report describes analyses and discusses the most of results obtained during the last, 2007 run.. (author)

    The EU is one of the most advanced places of petroleum substituting energy development. The EU is highly aware of environmental issues. For the COP3 held at Kyoto in December 1997, The EU gave more severe regulation of CO2 emission than the other advanced countries. The EU takes efforts in the development and introduction of energy effective for global environmental protection. In addition, research and development of geothermal, biomass and wave force energy are actively promoted in this place. Energy situations in this place are significant for predicting and analyzing the future trends of energy development and consumption in the other countries. Firstly, this report looks back toward energy demand held in check to a head at the beginning of the 1990`s. Secondly, supply of energy and cover of energy trend are described for recent years from the point of view. Thirdly, competitiveness of energy in EU countries are discussed from a position of energy density. Fourthly, circumstances about environmental issues are considered. Fifthly, the world market of energy is also considered. Finally, development of new energy and a trend of introduction with a sample of Sweden are introduced. 13 refs., 15 figs., 28 tabs.

  5. The EU sustainable energy policy indicators framework.

    2008-11-01

    The article deals with indicators framework to monitor implementation of the main EU (European Union) directives and other policy documents targeting sustainable energy development. The main EU directives which have impact on sustainable energy development are directives promoting energy efficiency and use of renewable energy sources, directives implementing greenhouse gas mitigation and atmospheric pollution reduction policies and other policy documents and strategies targeting energy sector. Promotion of use of renewable energy sources and energy efficiency improvements are among priorities of EU energy policy because the use of renewable energy sources and energy efficiency improvements has positive impact on energy security and climate change mitigation. The framework of indicators can be developed to establish the main targets set by EU energy and environmental policies allowing to connect indicators via chain of mutual impacts and to define policies and measures necessary to achieve established targets based on assessment of their impact on the targeted indicators representing sustainable energy development aims. The article discusses the application of indicators framework for EU sustainable energy policy analysis and presents the case study of this policy tool application for Baltic States. The article also discusses the use of biomass in Baltic States and future considerations in this field.

Nice in November was the scene of the EU sponsored Information Science Technologies, IST2000 exhibition, where CERN was invited to present a stand focussing on the benefits to small companies and start-ups from association with CERN and the IST program. Companies from France, Israel and the UK were featured. Network technology standards that CERN has helped to develop have been adopted by the European Space Agency for use in future space vehicles, and these too were on show. The challenges of data acquisition and data handling for the LHC are not insurmountable, but need to be approached with a combination of advanced technology and close industrial collaboration. One important aspect is that of high speed networking, an important component in both on-line and off-line computing (GRIDs). Real time data acquisition systems for the LHC require networks with high throughput, low latency, high rel...

    Delvaux, B.; Hunt, M.; Talus, K. (eds.)

    2011-12-15

    This third volume of EU Energy Law and Policy Issues presents an overview of some of the most recent developments taking place in the EU energy sector at a time when the Third Energy Package is likely to be or has been implemented in the EU Member States. In this respect, the reader will find a number of contributions which offer detailed and critical views on some of the main issues tackled by the Third Energy Package. Aside from this, the relationship between sector specific regulation and the rules of general competition law is examined in the second section of the book. This part also contains particular contributions on access regimes in gas and electricity markets as well as an innovating analysis on the methods for allocating allowances under the EU Emissions trading scheme and the interaction of such methods with EU state aid rules. Just like the previous volumes of the book, section III offers a deep insight into the external aspects of EU energy policy. Accordingly, the role of the Lisbon Treaty in promoting EU energy policy in the international arena is scrutinized in addition to the most recent evolutions on the topical issue of the Energy Charter Treaty. This section is completed with a daring contribution about the need to adopt a comprehensive theory of legal harmonization between the EU and third partners, which is presented using the specific case of the EU-Russia Energy Dialogue. Last but not least, some fundamental issues regarding the environmental aspects of EU Energy policy undergo an in-depth study in the final section of the book. Not only is the legal regime of energy efficiency in energy-related products examined, but also the issue of carbon constraining policies under WTO law. Finally, the electricity's industry viewpoint on the 2020 targets rounds off this third volume of EU Energy Law and Policy Issues with judicious comments.

  10. COMPETITION AND REGULATION IN THE EU ENERGY MARKET

    Directory of Open Access Journals (Sweden)

    Cristina Havriş

    2009-12-01

    Full Text Available When prices are high and public service obligations are not properly fulfilled, consumers wonder if they obtain what they need from the market. In electricity and gas markets of the EU Member States, apart from the persistence of high, non-transparent regulated prices, a number of shortcomings have been identified by the European Commission, such as a less than optimal network use for energy transmission, a lack of coordination and cooperation across borders by transmission system operators and national authorities, and a lack of transparent and simple procedures for dealing with consumers’ complaints. These are the main elements of the infringement proceedings that the European Commission decided to launch on 25 June 2009 against 25 Member States for non–compliance with certain Community provisions in the Second Internal Energy Market Package, which entered into force on 1 July 2007. Quite emblematic is the fact that it occurred the same day as the adoption of the Third Internal Energy Market Package aiming to ensure a proper functioning of the EU energy market. We intend to analyse what has happened in the recent years at the EU level in order to liberalise and remove the significant remaining obstacles to competition in the energy market.

  11. The Eastern Partnership and the EU-Turkey Energy Relations

    Directory of Open Access Journals (Sweden)

    Demiryol Tolga

    2014-10-01

    Full Text Available This article discusses the prospects and challenges of energy cooperation between the European Union (EU and Turkey within the context of the Eastern Partnership (EaP. Part of the EaP agenda is to advance energy cooperation between the EU and the partner states, particularly regarding the diversification of import routes. As an energy corridor between the EU and the hydrocarbon-rich Caspian states, Turkey is a strategic asset for European energy security. Turkey also has economic ties and political capital in the Caspian region that can help the EU reach out to its eastern partners. Despite robust incentives for cooperation, however, the EU-Turkey energy partnership has so far failed to meet mutual expectations. This article argues that this is primarily due to the inability of the two actors to credibly commit to regional energy cooperation. Commitment problem stems from two factors. First, the predominance of national energy interests over communal ones undermines credible commitment. The variation in energy needs of Member States prevents the EU from acting in unison in external energy policy. Similarly, Turkey also prioritizes its own energy security, particularly in its relations with suppliers, which undermines cooperation with the EU. Second, the EU and Turkey hold divergent perspectives on the potential political payoffs of energy cooperation. Turkish decision makers are convinced that energy cooperation warrants palpable progress in Turkey’s accession while most EU actors appear hesitant to establish a direct connection between energy and accession.

  12. Renewable energies in the EU-Accession States

    International Nuclear Information System (INIS)

    Reiche, Danyel

    2006-01-01

    The aim of this article is to discuss obstacles and success conditions for renewable energy sources in the EU-Accession States and to compare them with the framework in the EU-15. Besides the ten states which will join the EU in 2004, Bulgaria and Romania which will probably join in 2007 as well as Turkey are analysed. Most of these countries have had a century-long tradition in the utilisation of RES, primarily in biomass and hydropower. However, the communist regimes were convinced of the superiority of large-scale systems and converted the energy sectors into centralised units. Due to this dominating belief system more decentralised applications such as installations using renewable energies had to close. One crucial driving force for future renewable energy development in the Accession States comes from the stipulations set by the EU. The EU-Directive on the promotion of electricity produced from RES gives the new EU-members targets for their RES-development until 2010. Due to the Directive many Accession States have already begun to pay more attention to the topic and to introduce more systematic policies. Six of the Accession States have introduced minimum tariffs which were one of the main success conditions (besides a stable and sound investment programme as well as favourable background conditions) in the leading wind energy countries Germany and Spain. Beside the external pressure by the EU and other international obligations other driving forces such as the path dependencies in the national energy policies (degree of coal, oil and gas exploitation, nuclear power use, import dependency), the political support schemes for renewable energies, possibilities of obtaining external financial support and the cognitive environment are discussed. Finally similarities and differences between EU-15 and Accession States are worked out

    International Nuclear Information System (INIS)

    Blecic, P.; Bosnjakovic, B.; Frankovic, B.

    2013-01-01

    The paper discusses the main challenges and prospects of EU policy in the field of energy and climate change, without going into technical details, but establishes the main themes of sustainability: economy, environment and new jobs. It describes the foundations and the objectives of the current EU energy policy, and the reasons why the current approach to reduction of greenhouse gases emissions is disappointing. Also, the question is whether EU will achieve the renewable energy goals for the year 2020. The security of energy supply and availability is also considered, especially in view of high dependence on import energy in the today fragmented market. For the way forward to mid-century, the targets to year 2030 are of critical importance. Also, the paper gives an overview of the state of renewable energy and greenhouse gas emissions in Croatia.(author)

  14. High Intensity Beam Issues in the CERN Proton Synchrotron

    CERN Document Server

    Aumon, Sandra; Rivkin, Leonid

    This PhD work is about limitations of high intensity proton beams observed in the CERN Proton Synchrotron (PS) and, in particular, about issues at injection and transition energies. With its 53 years, the CERN PS would have to operate beyond the limit of its performance to match the future requirements. Beam instabilities driven by transverse impedance and aperture restrictions are important issues for the operation and for the High-Luminosity LHC upgrade which foresees an intensity increase delivered by the injectors. The main subject of the thesis concerns the study of a fast transverse instability occurring at transition energy. The proton beams crossing this energy range are particularly sensitive to wake forces because of the slow synchrotron motion. This instability can cause a strong vertical emittance blow-up and severe losses in less than a synchrotron period. Experimental observations show that the particles at the peak density of the beam longitudinal distribution oscillate in the vertical plane du...

    2001-01-01

    A reference facility for the inter-comparison of active and passive detectors in complex high-energy neutron fields is available at CERN since 1993. A positively charged hadron beam (a mixture of protons and pions) with momentum of 120 GeV/c hits a copper target, 50 cm thick and 7 cm in diameter. The secondary particles produced in the interaction traverse a shield made of either 80 cm of concrete or 40 cm of iron. Behind the iron shield, the resulting neutron spectrum has a maximum at about 1 MeV, with an additional high-energy component. Behind the concrete shield, the neutron spectrum has a second pronounced maximum at about 70 MeV and resembles the high- energy component of the radiation field at commercial flight altitudes created by cosmic rays. Recent Monte Carlo calculations are presented, performed for different beam conditions and shielding configurations in view of a possible upgrade of the facility for measurements related to the space program.

    New tuneable light-emitting Ca3Al8Si4O17N4:Ce(3+)/Tb(3+)/Eu(2+) oxynitride phosphors with high brightness have been prepared. When doped with trivalent cerium or divalent europium they present blue luminescence under UV excitation. The energy transfer from Ce(3+) to Tb(3+) and Ce(3+) to Eu(2+) ions is deduced from the spectral overlap between Ce(3+) emission and Tb(3+)/Eu(2+) excitation spectra. The energy-transfer efficiencies and corresponding mechanisms are discussed in detail, and the mechanisms of energy transfer from the Ce(3+) to Tb(3+) and Ce(3+) to Eu(2+) ions are demonstrated to be a dipole-quadrupole and dipole-dipole mechanism, respectively, by the Inokuti-Hirayama model. The International Commission on Illumination value of color tuneable emission as well as luminescence quantum yield (23.8-80.6%) can be tuned by controlling the content of Ce(3+), Tb(3+) and Eu(2+). All results suggest that they are suitable for UV light-emitting diode excitation.

    An experimental facility named HiRadMat, will be constructed at CERN to study the impact of the 450 GeV c−1 proton beam generated by the Super Proton Synchrotron (SPS) on solid targets. This is designed to study damage caused to the equipment including absorbers, collimators and others in case of an accidental release of the beam energy. This paper presents two-dimensional numerical simulations of target behavior irradiated by the SPS beam. These numerical simulations have shown that the target will be completely destroyed in such an accident, thereby generating high energy density (HED) matter. This study therefore suggests that this facility may also be used for carrying out dedicated experiments to study HED states in matter.

  19. EU Cooperation in the Energy Sector

    1998-01-01

    The European Union with 15 Member States at the end of the century and with 6 more countries in the accession phase has set up certain instruments which enhance energy cooperation among them and with third countries. The major dimensions of EU energy policy presented in the White Paper are the external dimension - globalization of markets, the increasing environmental concern, the technology developments and the EU institutional responsibilities. To contribute to these, certain EU initiatives and supporting actions are undertaken through the energy and the broader co-operation programmes like THERMIE, SYNERGY, SAVE, ALTENER, PHARE, etc. The THERMIE programme supports the demonstration application and dissemination of innovative and successful energy technologies. SYNERGY is a programme for energy co-operation with third countries in energy policy and strategy implementation issues. SAVE and ALTENER concentrate on the promotion and enhancement of energy efficiency practices and use of renewable respectively. PHARE is a technical assistance programme addressed to Eastern European Countries which are in the phase of transition to market economy. There are also other initiatives like the Transeuropean Energy Network (TEN) and the activities managed by the financial institutions namely the European Bank for Reconstruction and Development (EBRD) and the European Investment Bank (EIB). All this context of programmes and initiatives is modified from period to period in order to serve the EU energy policies and the developments in the energy markets. The recent agreement which came up from the Kyoto conference has actually influenced the direction of actions towards more intensive amelioration of environmental pollution. (author)

    2011-07-01

    Full Text Available The problems of renewable energy and regional development have gained a global dimension, as well as the concerns about the economic growth. Therefore, this study investigates the issue of managing renewable energy in the EU10 region, within the context of recovery and anticipated growth of the region. The findings of this study disclose that an important source of economic growth in the EU10 region's countries may be to start some new investments in renewable energy. In order to develop the field of renewable energy may be used EU funds, and may be envisaged different public-private partnership models, that may contribute to lower societal costs and increased deployment rates. The study was conducted by combining a wide variety of sources, such as statistics, reports and articles. The results reported in this study could be used for further research in the area of implementing green energy projects in the EU10 region. Another direction for further research could be to identify the most attractive countries for different renewable energy investment projects in the EU10 region.

  3. Conceptual and Institutional Aspects of EU Energy Policy (1990-2014

    Directory of Open Access Journals (Sweden)

    Yury V. Borovskiy

    2015-01-01

    Full Text Available Ideological and institutional framework of the European energy policy, which is still work in progress, is crucial to the EU as it faces new political and economic challenges related to the recent Ukrainian crisis. Even if key energy policy issues are still decided by member states as the EU only seeks to speak with one voice in energy matters externally, much progress has been made over the last two decades in terms of the EU's energy policy formulation and institutional development. The Lisbon Treaty made the energy policy a sphere of "shared competence" of EU institutions and member states. The European Commission's numerous policy documents ("White" and "Green books" 1995, 2000 and 2006 provided a basis for the development of an integrated energy market. Substantial progress has been achieved in the area of energy policy harmonization between the EU and neighboring countries (Energy Charter Treaty, European Energy Community. The Union's key energy policy areas also included supply diversification (trans-European energy networks, development of unconventional energy production, climate change and energy efficiency. Over the last decade climate changes has become a cornerstone of EU energy policy and is regarded by the EU as key to moderating energy demand and reducing import dependency.

    2017-01-01

    For nearly fifteen years, Virtual Visits at CERN have been bringing high-energy physics research directly to the public, through the use of videoconferencing systems at both ATLAS and CMS experimental sites. Over 30,000 people from all seven continents have participated in Virtual Visits to date, engaging students, teachers, artists, and general enthusiasts alike. While these connections often take place in science festivals or classrooms, the versatility of the medium allows the visit to be customized for any audience. In particular, Virtual Visit connections to the United States can integrate a population for which distance from the experiment may hinder education and awareness. Examples of such targeted audiences include US Congressional offices and other governmental institutions, to enhance dialogue about the benefits of global basic research, and historically underrepresented or underserved minority groups. Both the foundational work and future possibilities of US Virtual Visit connections is discussed.

    The Large Hadron Collider (LHC) at CERN will generate two extremely powerful 7 TeV proton beams. Each beam will consist of 2808 bunches with an intensity per bunch of 1.15x10(11) protons so that the total number of protons in one beam will be about 3x10(14) and the total energy will be 362 MJ. Each bunch will have a duration of 0.5 ns and two successive bunches will be separated by 25 ns, while the power distribution in the radial direction will be Gaussian with a standard deviation, sigma=0.2 mm. The total duration of the beam will be about 89 mus. Using a 2D hydrodynamic code, we have carried out numerical simulations of the thermodynamic and hydrodynamic response of a solid copper target that is irradiated with one of the LHC beams. These calculations show that only the first few hundred proton bunches will deposit a high specific energy of 400 kJ/g that will induce exotic states of high energy density in matter.

    The different energy sources, their costs and impacts on the environment determine the electricity production process. Energy planning must solve the existence of uncertainty through the diversification of power generation technologies portfolio. The European Union energy and environmental policy has been mainly based on promoting the security of supply, efficiency, energy savings and the promotion of Renewable Energy Sources. The recent European Commission communication “Towards an European Energy Union: A secure, sustainable, competitive and affordable energy for every European” establishes the path for the European future. This study deals with the analysis of the latest EUEnergy Union” goals through the application of Markowitz portfolio theory considering technological real assets. The EU targets are assessed under a double perspective: economic and environmental. The model concludes that implementing a high share of Renewable Energy target in the design of European Policies is not relevant: the maximization of Renewable Energy share could be achieved considering a sole Low Emissions of carbon dioxide policy. Additionally it is confirmed the need of Nuclear energy in 2030: a zero nuclear energy share in 2030 European Mix is not possible, unless the technological limits participation for Renewable Energy Sources were increased. - Highlights: • Implementing a high RES share target in European Policies could not be relevant. • Maximizing RES share could be achieved considering a sole Low Emissions policy. • The EU 2030 Nuclear energy 50% shutting down could be feasible. • Minimizing risk portfolio presents high diversification and energy security levels.

    2008-10-01

    Energy is quickly becoming an issue of integration and disintegration of the EU and will perhaps turn out to be the ultimate litmus test of political and economic unity in the EU, as energy issues are increasingly intertwined with wider security issues on the continent. Very often, economic issues are elevated to the political-strategic level, serving a different agenda than merely contributing to the energy policy agenda of the EU. The challenges to the EU and its member states in the energy sector are many: some issues are part of the wider geopolitical and geo-economic agenda, but some are also the product of the new EU that emerged after the fall of the Berlin Wall. The enlargement with member states that are asymmetrically dependent on oil and gas supplies mainly from Russia has further emphasised the growth of structural energy import dependency. Moreover, the new member states did not have the benefit of introducing the energy 'acquis', i.e. liberalisation, in a period of ample supply and relatively low prices. From 2004 onwards, energy has become tighter and more politicised. It was these developments that also uncovered the calculated risk of the old member states to embark on liberalisation without putting a crisis management policy into place. With the increasing worries about the security of supply and the asymmetric exposure of Eastern Europe to a single supplier, energy security issues also began to dominate the internal policy debates both in energy and in external relations. The new developments require the EU member states to consider how and to what extent their external energy policies should also be merged into a more EU-wide approach, if they can agree on the common risks that need to be averted and the common benefits gained, and if and how a crisis mechanism for fuels other than oil is needed to manage the perceived increased security of supply risks. Moreover, they should also consider the internal market design they set out to implement and

    2010-07-01

    The author intends to analyze the possible consequences of legal acts in energy policy and to check whether they may serve as competence for an EU energy policy according to the EG or Euratom treaties. She starts by outlining energy-political acts of the EU on the basis first of the former EC treaty and then of the Euratom treaty. These acts cover the issues of nuclear safety and nuclear waste, 'nuclear package' and safeguards monitoring. The next chapter presents the fundamentals of the competence distribution between the EU and its member states. On this basis, the energy-political competences for action of the former EG and Euratom treaties are discussed. This includes operative competences, harmonization competences, material restrictions of national energy policy, and structural instruments for making restrictions on national energy policies. The next chapter presents a critical assessment of the extent of the competence of Article 95 EG (now: Article 114 AEUV) and discusses the role of European law on grants and competition for the functioning of the European energy markets. The 'nuclear package' is reassessed from the view of competence law. Finally, the central new contents of the Lisbon treaty and their consequences for energy law are gone into. The importance of an energy competence title for the energy sector is questioned, and the interdependences between the Lisbon treaty and the Euratom treaty are analyzed. (orig.)

  12. Impact of energy policy instruments on the estimated level of underlying energy efficiency in the EU residential sector

    International Nuclear Information System (INIS)

    Filippini, Massimo; Hunt, Lester C.; Zorić, Jelena

    2014-01-01

    The promotion of energy efficiency is seen as one of the top priorities of EU energy policy (EC, 2010). In order to design and implement effective energy policy instruments, it is necessary to have information on energy demand price and income elasticities in addition to sound indicators of energy efficiency. This research combines the approaches taken in energy demand modelling and frontier analysis in order to econometrically estimate the level of energy efficiency for the residential sector in the EU-27 member states for the period 1996 to 2009. The estimates for the energy efficiency confirm that the EU residential sector indeed holds a relatively high potential for energy savings from reduced inefficiency. Therefore, despite the common objective to decrease ‘wasteful’ energy consumption, considerable variation in energy efficiency between the EU member states is established. Furthermore, an attempt is made to evaluate the impact of energy-efficiency measures undertaken in the EU residential sector by introducing an additional set of variables into the model and the results suggest that financial incentives and energy performance standards play an important role in promoting energy efficiency improvements, whereas informative measures do not have a significant impact. - Highlights: • The level of energy efficiency of the EU residential sector is estimated. • Considerable potential for energy savings from reduced inefficiency is established. • The impact of introduced energy-efficiency policy measures is also evaluated. • Financial incentives are found to promote energy efficiency improvements. • Energy performance standards also play an important role

  13. Global energy security and the implications for the EU

    2010-01-01

    The following article will analyse the global and geopolitical dimensions of the future international energy security and its implications for Europe and the EU-27. In this context, I will discuss to which extent the EU's newly proclaimed 'Energy Action Plan' of the EU Spring summit of 2007 and its declared common energy (foreign) policy are a sufficient strategy to cope with the new global and geopolitical challenges. The article concludes the following: (1) The interlinkage between globally designed traditional energy security concepts - that rely just on economic factors and 'market-strategies' - and domestic as well as regional political stability demands new thinking with regard to both energy supply security and foreign and security policies. (2) Although after the Russian-Ukrainian gas conflict in January 2006, energy security has forced its way up the European energy and foreign policy agendas, the EU-27 member states have largely failed to forge a coherent European energy security and energy foreign policy strategy after their Spring summit of 2007 because its declared political solidarity has been still lacking. But the 2nd Strategic Energy Review of November 2008 has recommended new initiatives to overcome this lack by promoting concrete infrastructure and other projects for enhancing Europe's supply security and its political solidarity as part of a common energy (foreign) policy. If the EU is able to implement the March 2007 and November 2008 decisions, the EU oil and gas demand will drastically reduce and freeze at current levels. In this case, Putin's energy policies by using Russia's energy resources and pipeline monopolies as a political instrument to enforce its economic and geopolitical interests will be proved as self-defeating in Russia's long-term strategic interests. It will reduce Gazprom's gas exports to a much smaller EU gas market than originally forecasted as the result of a deliberate EU policy of decreasing its overall gas demand and

    The one word that best describes the spirit of the EuCARD ’13 event (see here) that took place from 10 to 14 June at CERN is "collaboration". The event brought together more than 180 accelerator specialists from all over the world to celebrate the conclusion of the EuCARD project and to kick off its successor, EuCARD-2.   EuCARD-2 brings a global view to particle accelerator research in order to address challenges for future generations of accelerators. The project officially began on 1 May 2013 and will run for four years. With a total budget of €23.4 million, including an €8 million EU contribution, it will build upon the success of EuCARD and push it into an even more innovative regime. EuCARD-2 aims to significantly enhance multidisciplinary R&D for European accelerators and will actively contribute to the development of a European Research Area in accelerator science. This will be accomplished by promoting complementary expertise, cross-d...

    Thermoluminescent (TL) dosimeters are routinely used to monitor absorbed doses in many kinds of radiation fields which contain photons, electrons and neutrons. However, TLDs are mainly calibrated to photon sources. We studied the response of TLDs to complex secondary fields arising during the operation of high-energy accelerators (e.g. the Large Hadron Collider (LHC) at CERN). The experiments were conducted at the CERN-EU high-energy reference field facility (CERF). Six different LiF-based TLDs (MTS-N, MTS-7, MTS-6, MCP-N, MCP-7, MCP-6) were exposed to various secondary CERF's fields (both for high and low doses), by placing them at various positions: at the target and concrete top and side positions. For the experiment at the target the corresponding Monte Carlo calculations were also carried out using the FLUKA transport code and compared with experimental results. In addition, alanine dosimeters were used as an independent reference. The results show that TLDs are well suited for monitoring radiation fields around the LHC. Nevertheless, further investigations are required, some of which are in progress.

  17. CERN: Energy amplifier

    International Nuclear Information System (INIS)

    Anon.

    1995-01-01

    Even under the heavy burden of responsibility as CERN's Director General from 1989-3 the fertile mind of Carlo Rubbia the scientist was never still. A long-time Rubbia 'hobby' has been the search for new sources of nuclear energy, exploiting knowledge and skills from high energy physics. An initial objective was to adopt heavy ion techniques to induce controlled thermonuclear fusion, but in 1994 this quest changed direction. Putting the problems of thermonuclear fusion aside, Rubbia began to explore an alternative route to energy production through controlled nuclear fission. The idea is to use a particle accelerator producing neutrons by spallation (interaction of particles with a target) to feed a fuel/moderator assembly where the neutrons multiply by fission chain reactions. If the energy liberated becomes substantially greater than that needed to drive the accelerator, the process has a net gain and becomes selfsupporting. Hence the name ''Energy Amplifier'' (EA). Similar systems for energy production or for nuclear waste incineration have been proposed at Los Alamos and in Japan and Russia, but appear to require the prior development of innovative linear accelerators. For Rubbia's Amplifier, the requisite accelerator is a reasonable extrapolation of an existing cyclotron such that at the Swiss Paul Scherrer Institute. Moreover, the EA would require fuel rods very similar to those of conventional reactors, rather than demand-ing new technology using liquid fuel loops (molten salts) with on-line separation of radioactive products. Unlike a reactor, the EA's fission reaction is not self-sustaining: it is sub-critical and needs a continuous supply of neutrons from the accelerator. This makes Chernobyl-type meltdowns unlikely: if the accelerator stops, the reaction stops too. Another major advantage is that the old dream of using thorium as a fuel is now made possible. Thorium is not itself fissile, but under neutron

    2012-01-01

    Once confined to the UK context – where it was struggling to receive political recognition for years – the concept of energy (or fuel) poverty is slowly entering the EU's agenda, where it has crept into a number of regulatory documents and policy proposals. Using evidence gathered from an international workshop and semi-structured interviews with decision-makers, experts and advocacy activists in Brussels and Sofia, this paper explores the adoption of policies aimed at addressing energy poverty within (i) the organisational context of the EU; and (ii) national state institutions in Bulgaria – a member state facing considerable problems at the energy affordability – social inequality nexus. While the former are largely nascent and poorly co-ordinated, the latter have already been implemented de jure to a significant extent. However, many unresolved issues surrounding their de facto implementation remain. At the same time, national policy makers remain largely unaware of the existence of direct energy poverty related initiatives at the EU level. - Highlights: ► This paper explores the adoption of energy poverty policies within the EU and Bulgaria. ► We establish the existence of a range of nascent efforts to address the issue at EU level. ► Bulgaria has been good at implementing EU energy poverty relevant directives. ► However, policy makers speak a different language when it comes to direct energy poverty action.

  19. Europe, the EU and its 2050 Energy Storylines

    International Nuclear Information System (INIS)

    De Jong, J.; Weeda, E.

    2007-12-01

    This paper seeks to explore some of the conditions under which energy policy could be formulated in and by the European Union (EU) over the next 40 years. The development of energy policy at the EU level is addressed from a wider historical perspective, taking into account a number of factors that influence both the EU project and its energy supply security. These factors include the EU's international orientation and cooperation; the EU 'economic community of law' paradigm; the EU's (failing?) external leadership role; the impact of the fall of the Berlin Wall; and Europe's talents for creativity and improvisation. These factors are discussed in somewhat greater depth in the context of the formulation of an all-EU energy policy. The global energy policy environment is briefly discussed, indicating that energy resources for the world are less at stake than their access. On this basis, a closer look is taken at the theoretical and practical aspects of using scenarios as a tool for energy policy-making. A few examples are presented, and it is argued that scenarios should basically be addressed on the basis of storylines. Storylines do require a set of specific parameters, and in this case the choice was made to use the various roles played by stakeholders for intervening in markets and in the world order. This choice is argued on the basis of the global interrelations that are currently influencing resource policies in general and energy in particular. Market efficiency, climate change, poverty issues, geopolitics and global coordination mechanisms are considered, leading to the two policy dimensions of 'nationalism' versus 'globalism' and 'heavy' versus 'light' government as the axes for the scenarios and storylines. This paper develops four storylines that are conceivable and inherently consistent. They are labelled with names that refer not only to their content, but also to the political and societal climate prevailing in the region. The first, 'l'Europe des

    , the facility was commissioned by measuring the calibration quantities of interest, e.g. H*(10), as a function of the source-to-detector distance. In the case of neutron measurements, a comparison with the Monte Carlo results was carried out; in fact, the neutron scattering can be an important issue and the Monte Carlo method can contribute to its estimation and optimization. Neutron calibrations often need to be performed at neutron energies or spectra very much different from those generated by radioactive sources employed in standard calibration laboratories. Unfortunately, fields with a broad neutron spectrum extending to a few GeVs are very rare and the scientific community is calling for worldwide sharing of the existing facilities. The CERN RP group has been managing the CERN-EU high-energy Reference Field (CERF) facility for 20 years, which is a unique calibration field in its kind. CERF is a workplace field that reproduces the neutron spectrum encountered in the vicinity of high-energy accelerators and at commercial flight altitudes. Within the context of providing a well-characterized workplace field to the scientific community, Monte Carlo simulations were performed with the present development version of the FLUKA code. The simulations were compared with experimental measurements showing promising results for the future ISO accreditation of the facility as workplace reference facility. Even though the accreditation process is fairly long, the work achieved so far is setting the bases to start this process in the right way.

    2006-12-01

    In early March 2006, the European Commission re-launched the discussion on an Energy Policy for Europe with the 2006 publication of its Green Paper 'Secure, Competitive and Sustainable Energy for Europe'. This manifests the EU's will to broaden its reflection on its future energy systems, taking into account increasing market liberalisation and globalisation, environmental pressures, technological challenges and the growing import dependency from politically unstable regions. Other major contributions to this debate include the climate change communication 'Winning the battle against climate change' (published in 2005), the Green Paper on Energy Efficiency (2005), the Energy Efficiency Action Plan (2006), the ongoing works of the High Level Group on Competitiveness, Energy and the Environment (2006) and the enquiry into the energy sector by DG Competition of the European Commission in 2006. The Spring European Council in March 2006 welcomed the Energy Policy Green Paper and committed itself adopting a prioritised Action Plan at its spring session in 2007, to be prepared by the European Commission and the Energy Council. Early next year, the European Commission will table both the EU Strategic Energy Review, accompanied by a number of sectoral policies and a Green Paper on future climate change policy for the period post-2012 when the Kyoto Protocol expires. Both the EU Strategic Energy Review and the post-2012 Green Paper will outline the European Union (EU) 'energy and climate change vision' and propose a roadmap towards achieving EU energy and climate change objectives, namely, how to ensure the competitiveness of European industries while at the same time combating climate change and ensuring security of energy supply. To contribute to this debate, the CEPS multi-stakeholder Task Force on 'energy policy for Europe' has presented this Interim Report, which attempts to develop the key elements for an EU energy policy framework.

    The UK international participation is mainly at CERN although some British high energy physicists work at DESY in Germany, the Fermi Laboratory in the USA and, indeed, elsewhere as well. The UK subscription to CERN is 16% of the budget. The present state of high energy physics at CERN is summarized and the building of LEP explained. The Group's recommendations are that the UK's financial contribution to CERN should continue until LEP is built (by the early 1990s) but should then, because of the prevailing financial climate gradually be reduced by 25%.

    This paper studies the scintillation process in CsI:Eu crystal exposed to the pulse electron irradiation (E=0.25 MeV, t 1/2 =15 ns and W=0.003 J/cm 2 ). It has been proved that the energy transfer from the lattice to Eu 2+ ions in CsI:Eu occurs through the re-absorption of STE emission. The proposed model rests on the following experimental facts: (1) the activator emission at 2.68 eV rises gradually after the decay of the excitation pulse even at temperature lower than 90 K when V k centers are immobile; (2) the rise time of 2.68 eV emission and the decay time of STE emission have the same temperature dependences at T=78–300 K; (3) the excitation spectrum of 2.68 eV emission overlaps the emission spectrum of STE. -- Highlights: • The scintillation process in CsI:Eu was studied under pulsed electron irradiation. • A model of the energy transfer from the lattice to Eu 2+ ions in CsI:Eu was proposed. • Eu 2+ ions in CsI:Eu reabsorb the π-emission of self-trapped excitons

  6. Solar Energy: Incentives to Promote PV in EU27

    Directory of Open Access Journals (Sweden)

    María del P. Pablo-Romero

    2013-11-01

    Full Text Available The growth in the use of renewable energies in the EU has been remarkable. Among these energies is PV. The average annual growth rate for the EU-27 countries in installed PV capacity in the period 2005-2012 was 41.2%. While the installed capacity of PV has reached almost 82 % of National Renewable Energy Action Plan (NREAP targets for the EU-27 countries for 2020, it is still far from being used at its full potential. Over recent years, several measures have been adopted in the EU to enhance and promote PV. This paper undertakes a complete review of the state of PV power in Europe and the measures taken to date to promote it in EU-27. 25 countries have adopted measures to promote PV. The most widespread measure to promote PV use is Feed- in Tariffs. Tariffs are normally adjusted, in a decreasing manner, annually. Nevertheless, currently, seven countries have decided to accelerate this decrease rate in view of cost reduction of the installations and of higher efficiencies. The second instrument used to promote PV in the EU-27 countries is the concession of subsidies. Nevertheless, subsidies have the disadvantage of being closely linked to budgetary resources and therefore to budgetary constraints. In most EU countries, subsidies for renewable energy for PV are being lowered. Twelve EU-27 countries adopted tax measures. Low-interest loans and green certificate systems were only sparingly used.

According to this, such issues as country's energy security, usage of new energy sources, its economy and environmental consequences of irrational use of energy resources are becoming more acute. The article is devoted to various kinds of alternative energy sources, in particular, "green energy" and the issue of increasing use of renewable energy sources. The main goal of the publication is to analyze the energy policy of the EU countries, the expansion of renewable energy potential as the most energy-efficient sources.

    The 15th CERN Hardronic Festival took place on 17 July on the terrace of Rest 3 (Prévessin). Over 1000 people, from CERN and other International Organizations, came to enjoy the warm summer night, and to watch the best of the World's High Energy music. Jazz, rock, pop, country, metal, blues, funk and punk blasted out from 9 bands from the CERN Musiclub and Jazz club, alternating on two stages in a non-stop show.  The night reached its hottest point when The Canettes Blues Band got everybody dancing to sixties R&B tunes (pictured). Meanwhile, the bars and food vans were working at full capacity, under the expert management of the CERN Softball club, who were at the same time running a Softball tournament in the adjacent "Higgs Field". The Hardronic Festival is the main yearly CERN music event, and it is organized with the support of the Staff Association and the CERN Administration.

  9. Europe, the EU and its 2050 Energy Storylines

    2007-12-15

    This paper seeks to explore some of the conditions under which energy policy could be formulated in and by the European Union (EU) over the next 40 years. The development of energy policy at the EU level is addressed from a wider historical perspective, taking into account a number of factors that influence both the EU project and its energy supply security. These factors include the EU's international orientation and cooperation; the EU 'economic community of law' paradigm; the EU's (failing?) external leadership role; the impact of the fall of the Berlin Wall; and Europe's talents for creativity and improvisation. These factors are discussed in somewhat greater depth in the context of the formulation of an all-EU energy policy. The global energy policy environment is briefly discussed, indicating that energy resources for the world are less at stake than their access. On this basis, a closer look is taken at the theoretical and practical aspects of using scenarios as a tool for energy policy-making. A few examples are presented, and it is argued that scenarios should basically be addressed on the basis of storylines. Storylines do require a set of specific parameters, and in this case the choice was made to use the various roles played by stakeholders for intervening in markets and in the world order. This choice is argued on the basis of the global interrelations that are currently influencing resource policies in general and energy in particular. Market efficiency, climate change, poverty issues, geopolitics and global coordination mechanisms are considered, leading to the two policy dimensions of 'nationalism' versus 'globalism' and 'heavy' versus 'light' government as the axes for the scenarios and storylines. This paper develops four storylines that are conceivable and inherently consistent. They are labelled with names that refer not only to their content, but also to the political and

  12. The EU-Russia Energy Dialogue: Competition Versus Monopolies

    International Nuclear Information System (INIS)

    Milov, V.

    2006-01-01

    Russia and the European Union have clearly entered a new stage in their energy relations, defined by a growing asymmetry between a strengthened national monopoly on the supply side and a gradual opening of markets in Europe. In this context, a multitude of new approaches to EU Russia energy relations have been voiced recently by a wide variety of experts. Unfortunately, many of them involve 'defensive' solutions, driven by lack of mutual trust on both sides. Is a positive approach nevertheless still possible? The paper argues that competition is a key universal value in the development of a new and sustainable energy relationship between Russia and Europe. It is clear that EU competition regulators should take the lead in setting up a new framework for EU-Russia energy relations in the future. The success of their endeavors will not only determine the security of energy supply for European consumers, but also that of the Russian and Eurasian energy markets. (author)

  16. Russian energy in the EU market: Bolstered institutionsand their effects

    International Nuclear Information System (INIS)

    Romanova, Tatiana

    2014-01-01

    The article examines institutional changes in EU–Russian energy relations since 2000. The article explores the ability of transformed institutions to limit the politicisation of energy and to reconcile the EU competitive-market approach with Russian state capitalism. More specifically, the article focuses on changes in intergovernmental, transgovernmental and transnational interactions. The article demonstrates that the gradual strengthening of transgovernmental and transnational institutions has inhibited the politicisation of energy relations and facilitated regulative cooperation between the EU and Russia. However, the potential of shared institutions is constrained by internal institutions on both sides. In Russia, these obstacles are insufficient top-down delegation of responsibilities in the government and its great power aspirations. In the EU, key barriers include inter-institutional rivalries, the EU’s propensity to impose its legislation on external partners and the integration of energy policy with foreign policy. The article presents several policy implications. First, it is futile to institutionally impose the regulative paradigm of one partner on the other; rather, mutual dialogue is needed. Thus, institutions should be structured appropriately. Second, current depoliticisation will require the involvement of not only the EU and Russia but also transit countries, such as Ukraine. Third, transgovernmental and transnational cooperation should be nurtured because this is a useful channel for both information exchange and a regulative convergence of policy implementing mechanisms. Finally, this incremental regulative convergence is the only option available today for the EU and Russia; this is also a way to further depoliticise energy relations. - Highlights: • EU and Russia developed transgovernmental and transnational energy institutions. • It allowed them to face energy challenges: depoliticisation and market construction. • Internal EU and

    This report shows where Europe needs to be by 2030 in order to reach a fully renewable energy system by 2050. It is comes just as the European Commission is beginning to consider post-2020 climate and energy plans. Coming amid an increasingly active debate over what should follow current EU climate and energy legislation (the 20-20-20 package), WWF's report adapts the WWF Global 2050 Energy Scenario to the EU27 level and shows that by 2030 the EU could: use at least 38% less energy compared to a business as usual projection, generate more than 40% of its energy from renewable sources, by doing both, reduce its energy related greenhouse emissions by 50% compared to 1990 levels

    2013-05-15

    In 2009, the EU climate and energy package with targets for 2020 (the so-called 20-20-20 targets) were formulated. For the period after 2020, however, there are no legally binding targets at the EU level, except for a decreasing ETS cap which will not be sufficient in light of the ambition for 2050. This leads to uncertainty for market players, as project lead times are long and high upfront investments need to deliver returns well beyond 2020. In its Green Paper on a 2030 framework for climate and energy policies, the European Commission recognised the need for clarity regarding the post-2020 policy framework. Currently under discussion is whether the approach for 2020 should be continued towards 2030 in the form of three more stringent targets or that other approaches would be more appropriate. Within this context, the Dutch Government asked PBL Netherlands Environmental Assessment Agency and Ecofys for advice. PBL and Ecofys have subsequently analysed possible options for an EU policy framework for 2030 that will steer towards a low-carbon economy by 2050 in a cost-effective way.

  19. A common vision of energy risk? Energy securitisation and company perceptions of risk in the EU

    Directory of Open Access Journals (Sweden)

    Edward Stoddard

    2012-08-01

    Full Text Available In the European Union, energy security is provided by EU institutions, member states and commercial energy companies. However, despite the important role companies play in the provision of European energy security, it is not immediately evident to what extent the interests of the internationally operating energy firms are in line with the energy security preferences held by EU institutions. Analysing this relationship from the perspective of perceptions of energy security and energy business risk, this paper examines the extent to which there is a convergence between the energy securitisation of the European Commission and the observation of business risk as perceived by major European and international energy firms. It finds that while there are some significant areas where Commission securitisation contradicts energy company interests (e.g. climate change and energy prices there is also a high degree of convergence, in particular regarding perceptions of upstream political risk.

  20. Translating EU renewable energy policy for insular energy systems: Reunion Island's quest for energy autonomy

    2017-12-01

    Full Text Available Recognition of the negative impacts of climate change has led to agreement on the need to decarbonise energy systems through the employment of renewable energy. With many national and transnational policies in place, the options available to insular energy systems (IES differ from those of interconnected areas due to fragility in their production and distribution networks. Based on the concepts of policy mobility and translation, this study examines the interplay of EU renewable energy policy and insular governance processes aimed at achieving energy autonomy through renewable energy development. Reunion Island, a French Overseas Department and Region, is used as a case study to examine local energy governance processes, aspects that shape regional translation of national and EU policy, and the potential effects that create structures and pathways of energy transition. The study shows that Reunion Island’s regional Energy Governance Committee has significant application potential as a governance tool in other IES and small islands within the EU, but that renewable energy development is restricted due to national policy measures and path dependent governance structural constraints.

  3. Beam Dynamics Studies for High-Intensity Beams in the CERN Proton Synchrotron

    CERN Document Server

    AUTHOR|(CDS)2082016; Benedikt, Michael

    With the discovery of the Higgs boson, the existence of the last missing piece of the Standard Model of particle physics (SM) was confirmed. However, even though very elegant, this theory is unable to explain, for example, the generation of neutrino masses, nor does it account for dark energy or dark matter. To shed light on some of these open questions, research in fundamental particle physics pursues two complimentary approaches. On the one hand, particle colliders working at the high-energy frontier, such as the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), located in Geneva, Switzerland, are utilized to investigate the fundamental laws of nature. Alternatively, fixed target facilities require high-intensity beams to create a large flux of secondary particles to investigate, for example, rare particle decay processes, or to create neutrino beams. This thesis investigates limitations arising during the acceleration of high-intensity beams at the CERN Proton Synchrotro...

    The EuCARD-HFM task aims at realizing a 13 T dipole magnet with an aperture of 100 mm, which is a challenging step towards very high field accelerator magnets. This dipole, utilizing Nb$_{3}$Sn superconductor, will be used in the Fresca test facility at CERN. A preliminary design study has compared two possible design layouts for the EuCARD-HFM magnet: the cos-θ and the block. This report summarizes the conclusions of this study and justifies, on the base of quantitative and qualitative arguments, our decision to pursue the detailed design with the block layout.

  5. Shifting policy priorities in EU-China energy relations: Implications for Chinese energy investments in Europe

    2017-01-01

    Shifting energy policy priorities both in China and the EU (European Union) have transformed their bilateral relationship. In order to assess the impact of domestic policy priorities on bilateral energy cooperation and climate policy, this comparative study traces the evolution of EU and Chinese approaches to energy policy – and their relative emphasis on factors and frames such as availability, efficiency, affordability and environmental stewardship. Drawing on government documents and a data set of interviews with Chinese policy-makers, experts and academics in 2015–2016, the article argues that while the EU started with a strong emphasis on environmental stewardship and moved towards a focus on affordability and availability, China started with a strong emphasis on availability and has moved towards a greater emphasis on environmental stewardship. This shift in frames on the Chinese side and subsequent changes in subsidy structures and targets can partially explain the increase in investments in renewable energy technologies. The article concludes that the Chinese and EU perspectives have become more aligned over the past ten years, coinciding with an increasing trend towards renewable energy in Chinese energy investments in the EU, for example in Italy and the UK. - Highlights: • Compares dominant frames of energy policy in China and the European Union in the period 2005–2015. • Shows that there has been a convergence of policy frames between China and the EU. • Convergence on environmental stewardship is necessary but not sufficient for FDI in clean energy.

    The primary objective of this project is to identify the main political economic driving forces behind and barriers against the creation of an EU agreement on CO 2 /energy taxation. The analysis is based on a theoretical framework for understanding European integration and on detailed historical investigations into a process of EU negotiations concerning CO 2 /energy taxation that took place from the 1980s to 1994. Following the historical analysis of political economic driving forces and barriers, some overall perspectives on possible future developments within the field of EU CO 2 /energy taxation are finally advanced. The secondary objective of the project is to consider the possible effects on the EU negotiation process of Danish efforts to push the CO 2 /energy tax proposal from the late 1980s to 994. This analysis is based on the preceding historical analysis of the EU negotiation process, as well as further investigations into the national Danish development within the field of CO 2 /energy taxation, including accounts of Denmark's particular relations with the EU during the period in question. Finally, based on the likely future developments in the field EU CO 2 /energy taxation. Denmark's strategic opportunities are outlined. (BA)

    What is industrial radiography? It is a non-destructive method with a wide variety of applications, such as inspecting the quality of a weld. It uses high-energy radioactive sources or an X-ray generator.   Is this inspection technique used at CERN? Yes, it is widely used at CERN by the EN-MME Group, which outsources the work to one or more companies, depending on the workload. Is it possible to carry out radiography anywhere at CERN? Yes, it is possible to carry out radiography in any building/accelerator/experiment area at CERN (including in areas which are not normally subject to radiological hazards). When is radiography carried out? It normally takes place outside of working hours (7 p.m. to 6 a.m.). How will I know if radiography is taking place in my building?

  11. Renewable energies in the EU

    International Nuclear Information System (INIS)

    Heller, W.

    2008-01-01

    On January 23, 2008, the European Commission presented proposals in the form of a directive in an effort to give more specific shape to the objective adopted in the spring, i.e. to increase to 20% by 2020 the share of renewable energies in energy consumption in the Community. The proposal was to include legally binding goals for the overall share of renewable energy sources and the share of biofuels in the transport sector. The proposed directive on 'promoting the use of energy from renewable sources' calls upon each member state to ensure that its share of energy from renewable sources in the total energy consumption in 2020 at least corresponds to the target mentioned in Annex I Part A. In addition to the targets, the EU Commission charted a tentative course towards a minimum increase in the share of renewable energies in the period between 2011 and 2020. Finally, the member states are obliged to adopt national action plans. Unfortunately, the EU is missing an important target in its proposed directive: It should establish a framework for harmonized conditions promoting the use of renewable energies. One aspect to be welcomed is the introduction of a system of certificates of origin. It represents the entry, in principle, into a trading system with certificates of origin. The Green Package incorporates a wealth of new approaches. They will have to be tested and, if necessary, supplemented. Something else is evident, however: The directive established the foundations of a vast number of new regulations and red tape. (orig.)

    Full Text Available This article addresses the Energy Union from the perspective of energy efficiency. The research has a multidisciplinary character, which implies an economic analysis of an empirical type, but also a theoretical approach to the benefits of energy efficiency. The author analyzes the impact of the new energy regulations on efficiency in the European Union (EU, namely the in-depth review of the Directive on Buildings Energy Performance, the new heating and cooling strategy for the intelligent transformation of this sector, as well as the strategy for protecting vulnerable consumers. The effects of the new energy efficiency regulations are more significant in a number of Member States, but as soon as these will be applied throughout the EU, the beneficial effects of increased energy efficiency are likely to be felt in the entire EU area.

    For the electricity production of the EU there are differentiated structures which are based on different natural conditions, political decisions and investments of past decades. It has long been struggled committed to the ''one and correct'' energy policy. But precisely because of the differences in the individual countries, a unified energy and climate policy for the EU is not the right way. Diversity is a strength, which quite the EU Commission considered. Increased understanding of the specifics in other countries should just apply the German politics and the public that all too often judges from their own perspective. [German] Bei der Stromerzeugung in der EU bestehen differenzierte Strukturen, die auf unterschiedlichen natuerlichen Gegebenheiten, politischen Entscheidungen und Investitionen vergangener Jahrzehnte beruhen. Seit langem wird engagiert um die ''eine und richtige'' Energiepolitik gerungen. Doch gerade wegen der Unterschiede in den einzelnen Laendern kann eine vereinheitlichte Energie- und Klimapolitik fuer die EU nicht der richtige Weg sein. Vielfalt ist eine Staerke, was die EU-Kommission durchaus beruecksichtigt. Mehr Verstaendnis fuer die Spezifika in anderen Laendern sollte daher gerade die deutsche Politik und Oeffentlichkeit aufbringen, die allzu oft aus eigener Perspektive heraus urteilt.

    CERN, currently the largest organization in the world for particle physics, was founded in 1954. Originally located in Meyrin, at the outskirts of the city of Geneva in Switzerland, it has with time extended into neighboring France. The Theoretical Study Division of CERN, however, was created already in 1952, i.e., before the official inauguration of CERN. It was situated in Copenhagen. Christian Møller [1] was appointed (part-time) as the Director and there were two full time senior staff members, Gunnar Källén and Ben R. Mottelson. While constructing buildings and accelerators were in progress, an international conference was organized by CERN in the city of Geneva.

    2012-01-01

    The European Union's increasing reliance on imports from third countries is reason for unsettling concern. It is anticipated that by 2030, assuming a continuation of the recent trend, more than 70 per cent of the EU's energy consumption has to be imported. Notwithstanding such anticipation, European regulation addressing the external dimension of energy policy remained far and few between. In practise it is the individual countries being leading actors on the foreign energy relations stage exercising their own respective foreign policies. To cope with these threats to the EU foreign energy policy, the European Commission issued its long anticipated Communication on security of energy supply and international cooperation proposing concrete instruments on how energy foreign relations should be addressed in the future. But - does the Union have the power to bring about the crucial rebound?.

    CERN has a longstanding tradition of pursuing fundamental physics on extreme low and high energy scales. The present physics knowledge is successfully described by the Standard Model and the General Relativity. In the anti-matter regime many predictions of this established theory still remain experimentally unverified and one of the most fundamental open problems in physics concerns the question of asymmetry between particles: why is the observable and visible universe apparently composed almost entirely of matter and not of anti-matter? There is a huge interest in the very compelling scientiic case for anti-hydrogen and low energy anti-proton physics, here to name especially the Workshop on New Opportunities in the Physics Landscape at CERN which was convened in May 2009 by the CERN Directorate and culminated in the decision for the final approval of the construction of the Extra Low ENergy Antiproton (ELENA) ring by the Research Board in June 2011. ELENA is a CERN project aiming to construct a small 30 m ci...

  18. CERN: Higher energies at LEP

    1995-01-01

    This year will be the last that CERN's 27-kilometre LEP electron-positron collider will run routinely at around 45 GeV per beam. In the run, scheduled to begin in May, the four big experiments will top up their harvest so far of over 12 million Z particles for a final polishing of precision Z data. Behind the scenes, LEP is being prepared for higher energy running and a new phase of physics. After a brief technical stop in October, the aim is for a test run of up to 70 GeV per beam before the end of the year. Higher energy demands more radiofrequency power, which will be supplied by superconducting cavities. With this goal in mind, a programme of development work began at CERN over ten years ago, when LEP was still on the drawing board. Initially this effort focused on cavities made from sheet niobium, but later switched to copper covered by a sputtered niobium film, which gives better thermal and r.f. performance (September 1990, page 24). The first industrially-manufactured four-cavity niobium coated module, complete with its cryostat and r.f plumbing, was installed in LEP in 1993. Although it quickly achieved its nominal accelerating gradient of 6 MV/m, its reliability was affected by unforeseen problems in the associated power couplers. This delayed the installation schedule, but after a crash programme of design and modification of the power couplers, together with improvements in actual cavity design and manufacture, module supply and testing has now attained a satisfactory rhythm. Two modules installed in LEP amassed between them over 50 days of continuous running in 1994, and confidence is now high that the emphasis can shift towards integrating the cavities into LEP, rather than running the cavities themselves. During LEP's 1994-5 winter shutdown, modules are being installed at Points 2 and 6. Later, additional cavities will be installed in Points 2, 6 and 8 prior to embarking on the higher energy test run at the end of the year. After

    Since more than a decade, the European Commission through the Intelligent Energy for Europe programme and 29 partners, mainly European national energy efficiency agencies, have developed common methodologies on energy efficiency monitoring. This relies on two complementary tools: 1) ODYSSEE, an internet database on energy efficiency indicators. Around 200 indicators comparable and harmonised across countries are developed at sectoral or end uses levels, over the period 1980-2006 for the EU-15 countries and from 1990 for EU-10 countries + Croatia and Norway. 2) MURE, an interactive internet data base on energy efficiency policies. More than 1300 policies descriptions are stored. When available, ex-post evaluations are reported. Based on this material provided by each of partners representing all the EU-Members and Croatia, a cross countries analysis is carried by sector on the recent trends for the EU as a whole and by countries. This diagnosis of benchmark shows that countries which have performed the best differ according to the end uses. The contribution of the manufacturing sector in the energy savings seems slowing down compared to the late nineties. Inversely, results in transport seem now encouraging. The building sector has performed disappointingly despite numerous policies. Analysis of the policy mix across countries and its dynamic shows divergences between the EU-15 countries and the EU 10. Innovative measures can be found everywhere and are discussed extensively. These results become more and more widely used by member state to assess and interpret the target and the National Energy Efficiency Action Plan of the plan of the Energy Service directive recently launched. This report presents an analysis of energy efficiency trends in Croatian on the basis of energy efficiency indicators based on the ODYSSEE methodology. This analysis focuses on the period 1992-20041, in the energy consumption and energy efficiency in total and in sectors (industry

    As the LHC goes on line for its first exploration of the new high-energy frontier, CERN is also getting ready to enhance the support it provides for the analysis and interpretation of the emerging data.    The LHC Physics Centre at CERN (LPCC) has started up over the past couple of months, beginning with a series of initiatives ranging from Workshops to lectures for students. More details about the LPCC will be featured in a forthcoming Bulletin article. In the meantime, you can consult the LPCC web page, now available at http://cern.ch/lpcc. This offers the high energy physics community a portal to the LPCC's activities, as well as to useful resources, tools and information about the LHC physics programme, the progress of accelerator operations, relevant workshops and events around the world, and much more. The LPCC will shortly begin issuing a weekly bulletin of its own, distributed by e-mail. Members of the CERN physics community and subscribers to the CERN Bulletin will receive the ...

  1. Russia-EU energy efficiency cooperation in the Baltic region: the untapped potential

    Directory of Open Access Journals (Sweden)

    Romanova T. A.

    2014-03-01

    Full Text Available A stereotypical understanding of EU-Russia energy relations is often reduced to trade in oil and natural gas, which downplays the importance of energy efficiency cooperation. Such cooperation is promoted within the Energy Charter and its Treaty, Partnership and Cooperation Agreement, Energy Dialogue, Common Economic Space, Partnership for Modernisation. However, it lacks practical development, which relates to the instability of the legal environment in Russia, insufficient mechanisms of financial support for energy conservation projects and poor political support. Nevertheless, energy efficiency cooperation is capable of changing Russia-EU energy cooperation qualitatively: it offers a cheaper way to meet the needs of the EU, redefines interdependence between the parties, and introduces new elements of equality between them. Energy efficiency cooperation also transforms the patterns of the EU-Russia legal harmonization, creates new conditions for the convergence of regulations and the development of the middle class in Russia. Due to its specific features, cooperation in the Baltic Sea region becomes a locomotive of the Russia-EU energy efficiency cooperation, and, as a result, is capable of changing the quality of relations between the partners.

  3. EU Foreign Energy Policy. From Intergovernmentalism to Supranationalism

    Energy Technology Data Exchange (ETDEWEB)

    Ahner, N. [European University Institute, Florence (Italy)

    2012-01-15

    The European Union's increasing reliance on imports from third countries is reason for unsettling concern. It is anticipated that by 2030, assuming a continuation of the recent trend, more than 70 per cent of the EU's energy consumption has to be imported. Notwithstanding such anticipation, European regulation addressing the external dimension of energy policy remained far and few between. In practise it is the individual countries being leading actors on the foreign energy relations stage exercising their own respective foreign policies. To cope with these threats to the EU foreign energy policy, the European Commission issued its long anticipated Communication on security of energy supply and international cooperation proposing concrete instruments on how energy foreign relations should be addressed in the future. But - does the Union have the power to bring about the crucial rebound?.

  4. Advising the CERN Courier

    As an experiment, a 'CERN COURIER Advisory Panel' was set up two years ago. This Panel has now been granted continuing status. CERN COURIER is unique. It is now an international journal serving the whole high energy physics community, having moved far from its initial conception as the CERN 'house journal'. This international role emerged at the New Orleans meeting of Laboratory Directors in 1975, when it was decided 'to expand the COURIER coverage to give a balanced view of global activities in the high energy physics field'. During the first two years of its existence, the Advisory Panel understood its major task as improving the contact between the editors and the physics community, and helping to maintain a good balance of information. The Panel provided advice and comment but did not act at all as a refereeing body, leaving the editors with the journalistic freedom which should be theirs

  5. Fossil energy and GHG saving potentials of pig farming in the EU

    Nguyen, Thu Lan T.; Hermansen, John E.; Mogensen, Lisbeth

    2010-01-01

    In Europe, the highly developed livestock industry places a high burden on resource use and environmental quality. This paper examines pig meat production in North-West Europe as a base case and runs different scenarios to investigate how improvements in terms of energy and greenhouse gas (GHG) savings can be feasibly achieved. As shown in the results of the analysis, pig farming in the EU has a high potential to reduce fossil energy use and GHG emissions by taking improvement measures in three aspects: (i) feed use; (ii) manure management; and (iii) manure utilization. In particular, a combination of improvements in all mentioned aspects offers the highest savings potential of up to 61% fossil energy and 49% GHG emissions. In weighing these three aspects, manure utilization for energy production is found to be the most important factor in reducing fossil energy use and GHG emissions. However, when GHG implications of land use change and land opportunity cost associated with the production of feed crops (e.g. soy meal, cereals) are considered, reducing feed use becomes the main factor in improving GHG performance of EU pork.

    An integral part of CERN's comprehensive antiproton facilities is the LEAR low energy antiproton ring which came into action for physics in 1983 and has gone on to host many experiments looking at a wide range of physics topics. With CERN's big SPS proton-antiproton collider now in what could be its final production physics run after an illustrious career which began in 1981, the face of antiproton physics at CERN will change over the next few years. However LEAR runs independently of high energy antiproton operations, and any phasing out of collider operations has no direct impact on LEAR.

  9. Impact of thermal and intermediate energy neutrons on the semiconductor memories for the CERN accelerators

    CERN Document Server

    Cecchetto, Matteo; Gerardin, Simone

    A wide quantity of SRAM memories are employed along the Large Hadron Collider (LHC), the main CERN accelerator, and they are subjected to high levels of ionizing radiations which compromise the reliability of these devices. The Single Event Effect (SEE) qualification for components to be used in the complex high-energy accelerator at CERN relies on the characterization of two cross sections: 200-MeV protons and thermal neutrons. However, due to cost and time constraints, it is not always possible to characterize the SEE response of components to thermal neutrons, which is often regarded as negligible for components without borophosphosilicate glass (BPSG). Nevertheless, as recent studies show, the sensitivity of deep sub-micron technologies to thermal neutrons has increased owing to the presence of Boron 10 as a dopant and contact contaminant. The very large thermal neutron fluxes relative to high-energy hadron fluxes in some of the heavily shielded accelerator areas imply that even comparatively small therm...

    Eu 3+ doped alkali-barium-bismuth-tellurite (Eu 3+ :LKBBT) glasses were prepared by conventional melt quenching. Twelve emission bands including infrequent blue and green bands are observed and they almost cover whole visible spectral region under violet light radiation. The blue and green emissions of Eu 3+ rarely appeared in oxide glasses before, but they have been clearly recorded in Eu 3+ :LKBBT glasses even in the case of high concentration doping of Eu 3+ . The analysis based on spontaneous-radiative rate, energy gap and Raman scattering reveals that the obtaining of the abundant multichannel emissions of Eu 3+ is due to the higher refractive index and the lower phonon energy in LKBBT glass system

    Tb3+/Eu3+ co-doped lanthanum molybdate nanophosphors were synthesized by conventional co-precipitation method. The Powder X-ray diffractogram revealed the formation of highly crystalline tetragonal nanocrystals with space group I41/a and the detailed analysis of the small variation of lattice parameters with Tb/Eu co-doping on the host lattice were carried out based on the ionic radii of the dopants. The FTIR spectra is employed to identify the fundamental vibrational modes in La2-x-y (MoO4)3:xTb, yEu nanocrystals. The formation of nanocrystals by oriented attachment was recognized from the HR TEM images and the d-spacing calculated was in accordance with that corresponding to highest intensity diffraction peak in the XRD patterns. The constituent elements present in the samples were identified with the aid of EDAX and elemental mapping analysis. The broad Mo6+- O2- CTB and the sharp excitation peaks of Tb and Eu identified from the UV-Vis absorption spectra facilitates the suitability of exciting the phosphors effectively over NUV and visible region of the spectra. The possibility of energy transfer from host to Tb3+/Eu3+ ions and from Tb3+ to Eu3+ ions were confirmed from the PL excitation spectra monitoring 5D0→7F2 transition of Eu3+ ions around 615 nm. The correlated analysis of PL emission spectra, life time measurements and CIE diagram, upon different excitation channels elucidate the excellent luminescent properties of La2-x-y (MoO4)3:xTb, yEu nanophosphors with tunable emission colours in a wide range varying from yellow green region to reddish orange region and the efficient energy transfer from Tb3+ to Eu3+ ions in lanthanum molybdate host lattice. The Tb→Eu energy transfer efficiency and probability were calculated from the decay measurements and the values were found to be satisfactory for exploiting the prepared nanophosphors for the development of multifunctional luminescent nanophosphors.

    CERN defines and implements a Safety Policy that sets out the general principles governing safety at CERN. As an intergovernmental organisation, CERN further establishes its own Safety Rules as necessary for its proper functioning. In this process, it takes into account the laws and regulation of the Host States (France and Switzerland), EU regulations and directives, as well as international regulations, standards and directives. For the safety of cryogenic equipment, this is primarily covered by the Safety Regulation for Mechanical Equipment and the General Safety Instruction for Cryogenic Equipment. In addition, CERN has also developed Safety Guidelines to support the implementation of these safety rules, covering cryogenic equipment and oxygen deficiency hazard assessment and mitigation. An overview of the cryogenic safety rules and these safety guidelines will be presented.

    [RE(TMA)] anhydrous complexes (RE{sup 3+}: Y, Gd and Lu) present high red emission intensity with a quantum efficiency (~45%) for the [Y(TMA):Eu{sup 3+}] complexes, due to the absence of non-radioactive decay pathways mediated by water molecules. The complexes were prepared in mild conditions. All the compounds are crystalline and thermostable up to 460 °C. Phosphorescence data of the complexes with Y, Gd and Lu show that the T{sub 1} state of the TMA{sup 3−} anion has energy higher than the {sup 5}D{sub 0} emitting level of the Eu{sup 3+} ion, indicating that the ligand can act as an intramolecular energy sensitizer. The photoluminescence properties of the doped materials were studied based on the excitation and emission spectra and luminescence decay curves. The experimental intensity parameters (Ω{sub λ}), lifetimes (τ), radiative (A{sub rad}) and non-radiative (A{sub nrad}) decay rates were determined and discussed. - Highlights: • Highly luminescent Europium doped anhydrous complexes. • Efficient monochromatic red light conversion molecular devices (LCMDs). • High emission quantum efficiencies.

  17. Economic Impacts of the 1997 EU Energy Tax: Simulations with Three EU-Wide Models

    International Nuclear Information System (INIS)

    Jansen, H.; Klaassen, G.

    2000-01-01

    In March 1997 the European Commission adopted a proposal that increases existing minimum levels of taxation on mineral oils by around 10 to 25% and introduces excises for other energy products. This paper analyses the macroeconomic impacts of the proposal. It employs three models: HERMES, GEM-E3, and E3ME. All models confirm that the proposal will have positive macroeconomic impacts when the tax revenues are used to reduce social security contributions paid by employers. For the EU as a whole, both GDP and employment are expected to be higher and CO2 emissions are 0.9 to 1.6 percent lower. The positive EU-wide effects can be observed in practically all member states. The sector impacts are modest, with the energy sector expected to face the most negative impacts. Differences between model results are due to the model type (general equilibrium or macro-econometric), the EU countries covered and the way tax exemptions were handled. Crucial assumptions to obtain the 'double dividend' are the modelling of the labour market and the impacts on EU external trade. The sensitivity of the results for the use of tax revenues, tax exemptions and tax rate increases is assessed. 21 refs

The identification of these three aspects for assessing the evolution of EU — Russia energy relations is the novelty in the author’s approach. This study aims to identify the previous stages and assess the current state of EU — Russia energy dialogue, since they set out conditions for energy cooperation in the Baltic Sea region. This research is based on a political and legal analysis of various documents and employs various international relations theories (including integration theories. The article demonstrates that the EU nd Russia have made a transition to the integration agenda manifested in the Energy Dialogue (its current goal is the creation of a common European energy market. The author describes the process of gradual consolidation of transgovernmental and transnational institutions, which leads to depoliticization of cooperation and mutual socialization of the partners. Finally, legal discussions on the development of common rules have become more constructive. In sum, the current situation in EU — Russia energy relations is favourable and positively affects cooperation in the Baltic Sea region.

    A family of apatite-type fluorophosphate phosphors with general formula Sr3Gd(1-m-n)Na(PO4)3F:mTb3+,nEu3+ (SGN:mTb3+,nEu3+) have been synthesized via the high-temperature solid-state reaction method. Triple energy transfer processes from Gd3+ in the host to both Tb3+ and Eu3+, as well as from Tb3+ to Eu3+ have been verified by the photoluminescence spectra. Under the excitation of UV light, both green line from the transitions of Tb3+ and red line origin from the transitions of Eu3+ have been simultaneously observed in a single phase phosphor, which makes a promise for tunable color emissions from yellowish-green through yellow and ultimately to reddish-orange by simply adjusting the Eu3+ content (n) in SGN:0.20Tb3+,nEu3+ phosphors. Additionally, the energy transfer from the Tb3+ to the Eu3+ ions has been demonstrated to be a resonant type via a quadrupole-quadrupole mechanism based on the Dexter's theoretical model, and the energy transfer efficiency increases with an increase in Eu3+ concentration.

    The isostructral Zintl compounds EuIn2X2 (X = P,As) are investigated within density functional theory. We employ the local spin density approximation with onsite interaction (LSDA + U) for varying U from 0 eV to 7 eV to model the Coulomb repulsion of the Eu 4f electrons. The LSDA + U optical conductivity disagrees with the experimental spectrum, while the simple LSDA is successful. Contrary to the expectation, it is found that EuIn2X2 (X = P,As) has a large oscillator strength for the f → d transitions in the low-energy range (below 1.5 eV) in which effects of the joint density of states play a key role. The materials show a sizeable magneto-optical Kerr effect.

We employ the local spin density approximation with onsite interaction (LSDA + U) for varying U from 0 eV to 7 eV to model the Coulomb repulsion of the Eu 4f electrons. The LSDA + U optical conductivity disagrees with the experimental spectrum, while the simple LSDA is successful. Contrary to the expectation, it is found that EuIn2X2 (X = P,As) has a large oscillator strength for the f → d transitions in the low-energy range (below 1.5 eV) in which effects of the joint density of states play a key role. The materials show a sizeable magneto-optical Kerr effect.

  6. EU's external energy governance: A multidimensional analysis of the southern gas corridor

    2014-01-01

    The major objective of this paper is to apply a multidimensional lens to the European Union's (EU's) vision to the yet to be establish Southern Gas Corridor. I will argue that, the EU's natural gas vision towards the Caspian basin is based not only on bringing additional gas volumes to the EU markets in order to ensure physical security of supply. It is rather multidimensional external governance geared, firstly, towards absorbing all the actors along the whole value chain in to the EU's common energy regulatory framework and shifting energy provision from a bilateral political domain onto a multilateral market domain. Secondly, it is a process of diffusion of norms and values into the governance system of the energy partners. - Highlights: • EU's Southern Gas Corridor strategy is structurally embedded in its external governance. • The counterpart of the EU's energy imports is its attempt to export its acquis. • EU's energy security necessitates diffusion of norms and values to producers

    2016-01-01

    Full Text Available The energy issue is a long-term one of the most discussed, controversial topics in relations between the European Union and the Russian Federation. The intention of the present article is an attempt to overcome the largely non-discursive and in the security conditions anchored way of looking at the energy interaction of the EU and the RF and through an integration discourse to analyze EU energy relations with Russia in the years 2004 - 2014. In the theoretical level, the article is based on a critical constructivism, which in relation to the discourse as the main concept reflects a number of fundamental knowledge. At the methodological level, the article is based on the discourse analysis as a basic methodological tool through which the author examines the EU text documents.

    A dose of 2 mSv close to the body surface of a pregnant woman is considered by ICRP to assure a dose limit of 1 mSv to the foetus. Such an assumption depends on the energy spectrum and composition of the external radiation field and it was tested in radiation fields containing high-energy particles similar to those found around high-energy particle accelerators and in air-craft. Measurements of dose and dose equivalent were performed as a function of wall thickness using a tissue-equivalent proportional counter (TEPC) in radiation fields at the CERN-EU Reference Radiation Facility. Results are presented both with respect to integral quantities and event size spectra. The decrease in dose and dose equivalent at a depth equivalent to that of the foetus was typically 10% in a high-energy stray radiation field and in the case of PuBe source neutrons amounted to only 30%. It is concluded that it would be prudent under such exposure conditions to limit the dose of a pregnant woman to 1 mSv in order to assure that the dose to the foetus remains below the same limit.

  14. Nordic views on the next generation of EU energy efficiency targets

    2012-11-15

    EU has a target for energy efficiency for 2020, namely a 20 % reduction in the primary energy consumption relative to the PRIMES 2007 forecast for 2020. According to the new energy efficiency directive, that was agreed upon in June 2012, the target is that primary energy consumption must be no more than 1,474 Mtoe or that final energy consumption must be no more than 1,078 Mtoe by 2020. This is an absolute target for EU as a whole. There are no binding targets for member states. Due to the time lapse from goal setting, to policy formulation and practical implementation it is found that 2020 is just around the corner, and that it is high time to start discussion about the next goals. This could be concrete targets for 2030 and indicative targets for 2050. In this report target design and policy instruments are discussed from a Nordic perspective: Is it relevant to have an energy efficiency target? Should targets for energy efficiency be set in terms of primary energy or final energy? In absolute numbers or in relative numbers? Whether and how to divide the burden sharing? What are the Nordic positions of strength with regard to policy instruments? (LN)

  15. Extended Challenges for the EU's Climate and Energy Policy

    International Nuclear Information System (INIS)

    Haslauer, F.

    2015-01-01

    Market-driven climate and energy policies are far more effective than regulation-driven policies. It is time for the EU to rethink its energy strategy. The world is in the throes of a global energy transition as countries seek to meet rising demand by fundamentally changing their energy sectors. Global energy demand is expected to increase by 1.4 percent through 2030, with demand for electricity (a renewable) rising by more than 2 percent during this time period. The European Union has been front and center in this energy transition, seeking to meet three climate and energy targets by 2020: (1) reduce CO2 emissions, (2) increase renewables, and (3) become more energy efficient. Most countries are on track to meet the first two targets but meeting the third one has proved to be more difficult. This is largely because there is no single European power market. Energy policies and regulations are still driven by individual nations. If this continues, the EU energy transition will be costly - prices will shoot up and global competitiveness will suffer. It's time for the EU to work as one large entity and adopt market-driven policies. The advantages include a smoother energy transition in a growing economy, ability to leverage size for more competitive energy costs, and lower prices for consumers. In an ideal scenario, there is one overriding EU target for reducing CO2 emissions, and then the other two - renewables and energy efficiency - act as levers to meet that target. Essentially, the market decides which solutions are the most efficient. A market-driven energy strategy is funded from a CO2-emissions certificate market - to send the right price signals - or a CO2 tax to allocate costs to CO2 emissions. Rather than concentrating funds on feed in tariffs, funds are geared toward improving energy efficiency, research and development of renewables and running pilot programs. In this way, the EU 'incentivizes' innovation and funding is far less than what

    Full Text Available The luminescence of a Eu complex (EuL is enhanced by stabilization of the coordination structure in highly viscous ionic liquids. The EuL was found to maintain a stable single helical structure both in organic solvents and in the ionic liquids [BMIM][PF6] and [EMIM][PF6]. A colorless solution of EuL dissolved in [BMIM][PF6] exhibits bright red luminescence with a quantum yield of 32.3%, a value that is much higher than that in acetonitrile (12%. Estimated rate constants for the energy relaxation pathway indicate that the energy transfer efficiency is enhanced in [BMIM][PF6] as a result of the suppression of molecular fluctuations in the ligands. Additionally, a highly luminescent helical structure is preserved in [EMIM][PF6] up to 120 °C.

    1987-01-01

    QCD lattice calculations predict that, at sufficiently high energy densities, hadronic matter undergoes a transition to a new phase of matter, the quark-gluon plasma, in which quarks and gluons are deconfined over a relatively large volume. It has been suggested that collisions between heavy nuclei at ultrarelativistic energies may produce the energy densities, estimated to be greater than 2 to 3 GeV/fm 3 , necessary for this phase transition to occur. An important goal of the first experiments with ultrarelativistic heavy-ion beams at the SPS accelerator at CERN is to investigate the extent to which this suggestion is correct. The primary experimental quantity used for estimating the energy density is the transverse energy, E/sub T/. We present here energies measured at zero degrees, together with transverse energy measurements. Estimates of attained energy densities and preliminary transverse momentum distributions of neutral products are also presented. 24 refs., 7 figs

    In 2020, some leading EU energy and climate policies will expire. At present, the EU and its Member States are discussing the design of a post-2020 policy portfolio. In a discussion paper commissioned by the European Copper Institute, Ecofys shows that an EU-wide renewable energy target is a necessary part of a 2030 portfolio. The paper analyses, in detail, two realistic policy portfolio options for renewable energy, target-setting in particular: one 'decarbonisation-only' EU target with voluntary national targets for renewable energy, and one that includes an EU-wide renewable energy target, broken down into binding national targets. The analysis shows that the latter option, when supported by appropriate and improved EU and Member States' policies and measures, is most suitable in facilitating a European low-carbon economy.

    Full Text Available The evolution of the energy market and the intrinsic worldwide scope of environmental threats, such as climate change, are two elements that have pushed the world towards shared approaches to global governance via bilateral institutions and international regimes. This article, with the aid of an institutionalist approach, presents the current status of the EU-China relationship, which is characterised by high institutionalisation, and it underlines how their bilateral cooperation has progressively focused on energy and climate change-related issues. In particular, the article sheds some light on the linkages between energy, environment and climate change and how these have created the basis for the upgrade of the EU-China bilateral relationship to its current level. To do so, it underlines some of the tools, the main frameworks and some of the key outcomes of their bilateral cooperation in these fields.

    This paper explores the incentives for energy efficiency induced by the European Union Emissions Trading Scheme (EU ETS) for installations in the energy and industry sectors. Our analysis of the National Allocation Plans for 27 EU Member States for phase 2 of the EU ETS (2008-2012) suggests that the price and cost effects for improvements in carbon and energy efficiency in the energy and industry sectors will be stronger than in phase 1 (2005-2007), but only because the European Commission has substantially reduced the number of allowances to be allocated by the Member States. To the extent that companies from these sectors (notably power producers) pass through the extra costs for carbon, higher prices for allowances translate into stronger incentives for demand- side energy efficiency. With the cuts in allocation to energy and industry sectors these will be forced to greater reductions, thus the non-ET sectors like household, tertiary and transport will have to reduce less, which is more in line with the cost-efficient share of emission reductions. The findings also imply that domestic efficiency improvements in the energy and industry sectors may remain limited since companies can make substantial use of credits from the Kyoto mechanisms. The analysis of the rules for existing installations, new projects and closures suggests that incentives for energy efficiency are higher in phase 2 than in phase 1 because of the increased application of benchmarking to new and existing installations and because a lower share of allowances will be allocated for free. Nevertheless, there is still ample scope to further improve the EU ETS so that the full potential for energy efficiency can be realized. (orig.)

    To explore the 1 TeV energy scale where fundamental particle interactions should encounter new conditions, two major routes were proposed - a high magnetic field proton collider in the LEP tunnel, dubbed LHC for Large Hadron Collider, and the CERN Linear Collider (CLIC) to supply beams of electrons and positrons. Exploratory studies have shown that while CLIC remains a valid long-term goal, LHC appears as the most cost-effective way for CERN to enter the 1 TeV arena. High-field superconducting magnet prototype work demonstrates that a 'two-in-one' design supplying the 10 tesla fields needed to handle LHC's 8 TeV proton beams (collision energy 16 TeV) is a practical proposition.

    Full Text Available The Energy Union Strategy, launched in February 2015, is a vast project aiming at identifying a set of common responses to a series of present and future challenges in the field of energy. The question of energy security occupies a central position in EU’s relationships with its neighbours. In this context, economic and political ties with the Russian Federation in its role of major supplier of energy resources to EU member states are of crucial importance. Acquiring a higher degree of independence from the Russian supply of natural gas has been proclaimed as a national priority by several ex-Soviet republics. Moldova, Ukraine and Georgia have recently signed Association Agreements with the EU. We look into the early stages of the implementation of AA’s and analyse their consequences on the EU – Russia relations in the energy field. A series of common characteristics and possible developments in the field of energy are analysed.

CERN is an intergovernmental organisation subject to its own treaty. We are not part of the European Union, and several of our Member States, including Switzerland, in which we are headquartered, are not EU Members. Britain’s membership of CERN is not affected by the UK electorate’s vote to leave the European Union. We look forward to continuing the very constructive relationship we have shared with the UK, one of our founding members, long into the future. CERN was founded on the principle of international collaboration, and our success over the years is built on that. We will continue to work proactively to encourage ever-greater international collaboration in particle physics, and to help ensure that the UK continues to play a very active role. UK nationals remain eligible for all categories of employment at CERN, a...

    According to article 194 of the EU Lisbon Treaty, energy now falls within the province of European policy and is a sector for shared responsibility with member countries, in the same way as for the environment, transportation, the interior market and trans-European networks (article 4 of the Lisbon Treaty). The introduction in the Treaty of a chapter devoted to energy clearly has a political emphasis, as its shows the EU's attachment to the implementation of a coherent policy. However, its enactment carries with it not insignificant legal changes, because a specific and autonomous legal basis is established for the first time, thus allowing the Union to take decisions and actions in the area of energy.

    Ligand L, based on two do3a moieties linked by the methylene groups of 6,6'-dimethyl-2,2'-bipyridine, was synthesized and characterized. The addition of Ln salts to an aqueous solution of L (0.01 M Tris-HCl, pH 7.4) led to the successive formation of [LnL] and [Ln(2)L] complexes, as evidenced by UV/Vis and fluorescence titration experiments. Homodinuclear [Ln(2)L] complexes (Ln = Eu, Gd, Tb, Yb, and Lu) were prepared and characterized. The (1)H and (13)C NMR spectra of the Lu and Yb complexes in D(2)O solution (pD = 7.0) showed C(1) symmetry of these species in solution, pointing to two different chemical environments for the two lanthanide cations. The analysis of the chemical shifts of the Yb complex indicated that the two coordination sites present square antiprismatic (SAP) coordination environments around the metal ions. The spectroscopic properties of the [Tb(2)L] complex upon ligand excitation revealed conventional behavior with τ(H2O) = 2.05(1) ms and ϕ(H2O) = 51%, except for the calculation of the hydration number obtained from the luminescent lifetimes in H(2)O and D(2)O, which pointed to a non-integer value of 0.6 water molecules per Tb(III) ion. In contrast, the Eu complex revealed surprising features such as: 1) the presence of two and up to five components in the (5)D(0)→(7)F(0) and (5)D(0)→(7)F(1) emission bands, respectively; 2) marked differences between the normalized spectra obtained in H(2)O and D(2)O solutions; and 3) unconventional temporal evolution of the luminescence intensity at certain wavelengths, the intensity profile first displaying a rising step before the occurrence of the expected decay. Additional spectroscopic experiments performed on [Gd(2-x)Eu(x)L] complexes (x = 0.1 and 1.9) confirmed the presence of two distinct Eu sites with hydration numbers of 0 (site I) and 2 (site II), and showed that the unconventional temporal evolution of the emission intensity is the result of an unprecedented intramolecular Eu-to-Eu

    Luminescent and scintillation properties of polystyrene-based plastic scintillators with {beta}-diketone Eu complexes are investigated. A scintillator with dibenzoylmethane Eu complex containing two phenyl groups demonstrates the maximum scintillating efficiency. It is shown that plastic scintillators efficiency is dramatically decreased if {beta}-diketone derivatives contain no phenyl groups as substituents. This fact can be explained by exciplex mechanism of energy transfer from a matrix to Eu complex. - Highlights: > Fluorescent properties of polystyrene scintillators with {beta}-diketone complexes of Eu were studied. > Scintillating efficiency is increased with the number of phenyl groups in Eu complex. > This is related to exciplex mechanism of energy transfer from a polymer matrix to Eu complex.

    After having outlined that the Ukrainian crisis has revealed the challenge of the EU energy independence and the issue of its dependence, and also indicated the evolutions of gas imports for some European countries between 1995 and 2011, this publication discusses the level of this energy dependence as it appears through the evolution of energy resources, and through the evolution of the final energy mix. It also briefly comments the position of member states. Then, it analyses the influence of French choices on this dependence level (contribution of France to a lower dependence, evolution of energy dependence rates of European countries), and defines the potential role France could play and actions France could implement for a positive evolution of EU energy independence

    Israel (along with the US, Japan, Canada, the Russian Federation and India) is one of the CERN non- Member State nations targeted for substantial future participation in CERN's experimental programme, in particular for the LHC proton collider to be built in the 27-kilometre LEP tunnel and which was formally approved by CERN Council in December (January/February, page 1). In keeping with their illustrious scientific traditions, Israeli experimental physicists have collaborated in experiments at many of the world's major high energy Laboratories - Brookhaven, Fermilab and SLAC in the US, and in Europe, DESY, Hamburg, as well as CERN. However CERN, as the geographically closest major Laboratory (as well as the largest), plays a special role for Israeli scientists. At CERN, the advent of preparations in the early 1980s for the experimental programme at the LEP electron-positron collider was the signal for Israeli researchers to mount a concerted effort and contribute to one of the experiments - Opal - at a level comparable to that of major nations. This allowed Israeli teams to participate fully in the planning and construction phase of this branch of Big Science. Underlining this commitment, and to coordinate the various national agencies involved in this aspect of Big Science, in 1983 the Israel Commission for High Energy Physics (ICHEP) was formed. It is currently chaired by David Horn of Tel Aviv. The initial ICHEP/CERN contract established the official CERN/lsrael link under which, in the short-term, teams from three major research centres - the Weizmann Institute, Tel- Aviv University, and Haifa's Technion - contributed to Opal, as the flagship experiment, while providing a framework for longer-term collaboration. (At CERN, Israeli physicists also participate in the NA45 heavy ion experiment and the NA47 Spin Muon Collaboration - SMC.) Opal groups some 320 scientists from 32 research centres in eight countries, and includes a 21-strong Israeli

  17. Energy Vulnerability and EU-Russia Energy Relations

    Directory of Open Access Journals (Sweden)

    Edward Hunter Christie

    2009-08-01

    Full Text Available The concept of energy vulnerability is reviewed and discussed with a focus on Russia’s foreign energy relations, in particular those with European countries. A definition and a conceptual framework for quantifying energy vulnerability are proposed in the context of a review of recent research on energy vulnerability indices. In particular it is suggested that source country diversification should be reflected using the expected shortfall measure used in financial economics, rather than the Herfindahl-Hirschman or Shannon-Wiener indices, and that the former should then enter a calibrated function in order to yield expected economic loss. The issues of asymmetric failure probabilities and accidental versus intentional supply disruptions are then discussed with examples of recent Russian actions. Energy vulnerability measurement and modelling should ultimately inform policy. In particular, member states should legislate that no energy infrastructure project by one or more member states may increase the energy vulnerability of another member state. Additionally, European environmental policies, notably the EU ETS, should be amended so as to account for induced changes in energy vulnerability. Finally, member states should increase the level of transparency and disclosure with respect to gas import statistics and gas supply contracts.

  19. Modelling energy demand in the buildings sector within the EU

    Energy Technology Data Exchange (ETDEWEB)

    O Broin, Eoin

    2012-11-01

    In the on-going effort within the EU to tackle greenhouse gas emissions and secure future energy supplies, the buildings sector is often referred to as offering a large potential for energy savings. The aim of this thesis is to produce scenarios that highlight the parameters that affect the energy demands and thus potentials for savings of the building sector. Top-down and bottom-up approaches to modelling energy demand in EU buildings are applied in this thesis. The top-down approach uses econometrics to establish the historical contribution of various parameters to energy demands for space and water heating in the residential sectors of four EU countries. The bottom-up approach models the explicit impact of trends in energy efficiency improvement on total energy demand in the EU buildings stock. The two approaches are implemented independently, i.e., the results from the top-down studies do not feed into those from the bottom-up studies or vice versa. The explanatory variables used in the top-down approach are: energy prices; heating degree days, as a proxy for outdoor climate; a linear time trend, as a proxy for technology development; and the lag of energy demand, as a proxy for inertia in the system. In this case, inertia refers to the time it takes to replace space and water heating systems in reaction to price changes. The analysis gives long-term price elasticities of demand as follows: for France, -0.17; for Italy, -0.35; for Sweden, -0.27; and for the UK, -0.35. These results reveal that the price elasticity of demand for space and water heating is inelastic in each of these cases. Nonetheless, scenarios created for the period up to 2050 using these elasticities and an annual price increase of 3 % show that demand can be reduced by more than 1 % per year in France and Sweden and by less than 1 % per year in Italy and the UK. In the bottom-up modelling, varying rates for conversion efficiencies, heating standards for new buildings, end-use efficiency, and

    An analysis of the revised physics needs and recent progress in the technology of superconducting RF cavities have led to major changes in the speci cation and in the design for a Superconducting Proton Linac (SPL) at CERN. Compared with the rst conceptual design report (CERN 2000–012) the beam energy is almost doubled (3.5 GeV instead of 2.2 GeV), while the length of the linac is reduced by 40% and the repetition rate is reduced to 50 Hz. The basic beam power is at a level of 4–5MW and the approach chosen offers enough margins for upgrades. With this high beam power, the SPL can be the proton driver for an ISOL-type radioactive ion beam facility of the next generation (`EURISOL'), and for a neutrino facility based on superbeam C beta-beam or on muon decay in a storage ring (`neutrino factory'). The SPL can also replace the Linac2 and PS Booster in the low-energy part of the CERN proton accelerator complex, improving signi cantly the beam performance in terms of brightness and intensity for the bene t of al...

    Luminescent and scintillation properties of polystyrene-based plastic scintillators with β-diketone Eu complexes are investigated. A scintillator with dibenzoylmethane Eu complex containing two phenyl groups demonstrates the maximum scintillating efficiency. It is shown that plastic scintillators efficiency is dramatically decreased if β-diketone derivatives contain no phenyl groups as substituents. This fact can be explained by exciplex mechanism of energy transfer from a matrix to Eu complex. - Highlights: → Fluorescent properties of polystyrene scintillators with β-diketone complexes of Eu were studied. → Scintillating efficiency is increased with the number of phenyl groups in Eu complex. → This is related to exciplex mechanism of energy transfer from a polymer matrix to Eu complex.

    A summary of the present status and future plans for heavy ion experiments at CERN-SPS and CERN-LHC accelerators is given. The planned three phases give possibilities to study the properties of the quark-gluon-plasma (QGP). At the present stage the feasibility of high energy ion-ion experiments with their very abundant secondary hadron production, shows that there is a chance to obtain high densities, and to look for the onset of new, collective phenomena. In a second phase, there should be a chance to obtain more conclusive evidence for the onset of quark deconfinement. In the third stage, the average energy densities rise above the deconfinement threshold, so that a study of the properties of QGP should become possible. (G.P.)

    In this work, we study the energy transfer mechanism from ZnO nanocrystals (ZnO-nc) to Eu 3+ ions by fabricating thin-film samples of ZnO-nc and Eu 3+ ions embedded in a SiO₂ matrix using the low-cost sol-gel technique. The time-resolved photoluminescence (TRPL) measurements from the samples were analyzed to understand the contribution of energy transfer from the various ZnO-nc emission centers to Eu 3+ ions. The decay time obtained from the TRPL measurements was used to calculate the energy transfer efficiencies from the ZnO-nc emission centers, and these results were compared with the energy transfer efficiencies calculated from steady-state photoluminescence emission results. The results in this work show that high transfer efficiencies from the excitonic and Zn defect emission centers is mostly due to the energy transfer from ZnO-nc to Eu 3+ ions which results in the radiative emission from the Eu 3+ ions at 614 nm, while the energy transfer from the oxygen defect emissions is most probably due to the energy transfer from ZnO-nc to the new defects created due to the incorporation of the Eu 3+ ions.

    Industrial boilers are widely applied in such fields as factory power, building heating, and people’s lives; China is the world’s largest producer and user of industrial boilers, with very high annual energy consumption; clear requirements have been put forward by China on the energy efficiency since the “11th Five-year Plan” with the hope to save energy and reduce emission by means of energy efficiency standards and regulations on the supervision and control of various special equipment. So far, the energy efficiency of industrial boilers in China has been improved significantly but there is still a gap with the EU states. This paper analyzes the policies of energy efficiency, implementation models and methods of supervision and implementation at the EU level from laws, regulations, directives as well as standards; the paper also puts forward suggestions of energy conserving and emission reduction on the improvement of energy conserving capacity of industrial boilers in China through studying the legislations and measures of the developed countries in energy conserving of boilers.

    A group of color tunable Sr 3 LaNa(PO 4 ) 3 F:Tb 3+ ,Eu 3+ phosphors were prepared by conventional high temperature solid state method. The phase structures, luminescence properties, fluorescence lifetimes and energy transfer were investigated in detail. Under 369nm excitation, owing to efficient energy transfer of Tb 3+ →Eu 3+ , the emission spectra both have green emission of Tb 3+ and red emission of Eu 3+ . An efficient energy transfer occur in Tb 3+ , Eu 3+ co-doped Sr 3 LaNa(PO 4 ) 3 F phosphors. The most possible mechanism of energy transfer is dipole-dipole interaction by Dexter's theoretical model. The energy transfer of Tb 3+ and Eu 3+ was confirmed by the variations of emission and excitation spectra and Tb 3+ /Eu 3+ decay lifetimes in Sr 3 LaNa(PO 4 ) 3 F:Tb 3+ ,Eu 3+ . The color tone can tuned from yellowish-green through yellow and eventually to reddish-orange with fixed Tb 3+ content by changing Eu 3+ concentrations. The results show that the prepared Tb 3+ , Eu 3+ co-doped color tunable Sr 3 LaNa(PO 4 ) 3 F phosphor can be used for white LED. Copyright © 2017 Elsevier B.V. All rights reserved.

    2017-01-01

    The new albedo dosemeter-type AWST-TL-GD 04 has been calibrated in the CERF neutron field (CERN-EU high-energy Reference Field). This type of albedo dosemeter is based on thermoluminescent detectors (TLDs) and used by the individual monitoring service of the Helmholtz Zentrum Muenchen (AWST) since 2015 for monitoring persons, who are exposed occupationally against photon and neutron radiation. The motivation for this experiment was to gain a field specific neutron correction factor N n for workplaces at high-energy particle accelerators. N n is a dimensionless factor relative to a basic detector calibration with 137 Cs and is used to calculate the personal neutron dose in terms of H p (10) from the neutron albedo signal. The results show that the sensitivity of the albedo dosemeter for this specific neutron field is not significantly lower as for fast neutrons of a radionuclide source like 252 Cf. The neutron correction factor varies between 0.73 and 1.16 with a midrange value of 0.94. The albedo dosemeter is therefore appropriate to monitor persons, which are exposed at high-energy particle accelerators. (authors)

    The study attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973-87 and complements an earlier study made in 1973-75 (see CERN Report 75-5). Interviews were carried out in 160 European firms, who supplied estimates of increased sales and cost savings due to CERN contracts. This ''economic utility'' totals 3107 million Swiss francs (up to the year 1987), compared to sales to CERN amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973-82 will have generated Economic Utility amounting to about 60% of the overall cost of the Organization during the same period. In 1982, about 75% of the increased turnover due to CERN resulted from sales to markets outside high energy particle physics, for example, railways, shipbuilding, refrigeration, power generation and distribution, and health care. The quantification model used is discussed in detail and some specific cases are presented as examples.

    These Proceedings contain written versions of most of the lectures delivered at the 1988 CERN School of Computing. Five lecture series concerned different aspects of parallel and vector processing: advanced computer architectures; parallel architectures for neurocomputers; Occam and transputers; vectorization of Monte Carlo code; and vectorization of high-energy physics code. Software engineering was the topic of three series of lectures: formal methods for program design; introduction to software engineering; and tutorial lectures on structured analysis and structured design. Lectures on data-acquisition and recording were followed by lectures on new techniques for data analysis in high-energy physics. Computer-assisted design of electronic systems, and silicon compilation and design synthesis for digital systems, were the topic of two other, closely related, lecture series. Lectures on accelerator controls and on robotics are also recorded in these Proceedings. Various other aspects of computing were covered in lectures on high-speed networks document preparation systems, interpersonal communication using computers, and on Fortran 8x. Two general lectures gave an introduction to high-energy physics at CERN. (orig.)

    The Energy Transition (''Energiewende'') is one of the hot topics of the political debate in Germany for some years. As a consequence of ongoing European integration, EU level politics have gained growing importance. The focus of this study is on the interaction of German and EU energy and climate policies. How have German actors influenced EU policy-making processes and in how far are EU policies relevant for national policy-making in Germany? Three case studies look at processes in the fields of electricity market regulation, renewable energy policy and climate protection between 2007 and 2013.

    After directing the CERN physics schools since 1993, Egil Lillestøl has handed over to Nick Ellis. At the same time, Hélène Haller has taken over from Danielle Métral as the schools’ administrator. From left to right: Nick Ellis, Hélène Haller, Danielle Métral and Egil Lillestøl.The CERN physics schools for young experimentalists date back to the 1960s and as early as 1971 collaboration with the Joint Institute for Nuclear Research (JINR) in Dubna led to the Joint CERN-JINR schools, which reached beyond CERN’s Member States every two years. Then, in 1993, CERN and JINR agreed to organize the schools jointly every year, as the European School for High-Energy Physics. Egil Lillestøl, has not only run this school very successfully since then, but also created the CERN Latin American School of High-Energy Physics, beginning in 2001. Danielle Métral has been responsible for the schools’ administration since 2001, both for t...

  6. Spinoff from high energy physics

    Hoffmann, Hans

    1994-01-01

    This year the CERN Courier is featuring the spinoff and technological benefits arising from research in fundamental physics. After initial illustrations in applied data processing sectors, this article by Hans Hoffman of CERN examines the rationale and underlying objectives of the 'new awareness' of the market value of basic science. He is the Chairman of a new panel on the subject set up recently by the International Committee for Future Accelerators (ICFA). The other members are: Oscar Barbalat of CERN, Hans Christian Dehne of DESY, Sin-ichi Kurakawa of KEK, Gennady Kulipanov of the Budker Institute (Novosibirsk), Anthony Montgomery, formerly of the SSC, A. H. Walenta of Siegen, Germany, and Zhongqiang Yu of IHEP Beijing. High energy physics - the quest to find and understand the structure of matter - is mainly seen as an essential part of human culture. However this basic science increasingly has to jostle for funding attention with other branches of science. Applied sciences aim for a rapid transformation of investment cash into viable market products. In times of economic difficulties this is attractive to funding agencies and governments, and economic usefulness and technological relevance also become criteria for a basic science like high energy physics.

  7. [The Big Data Game : On the Ludic Constitution of the Collaborative Production of Knowledge in High-Energy Physics at CERN].

    Science.gov (United States)

    Dippel, Anne

    2017-12-01

    This article looks at how games and play contribute to the big data-driven production of knowledge in High-Energy Physics, with a particular focus on the Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN), where the author has been conducting anthropological fieldwork since 2014. The ludic (playful) aspect of knowledge production is analyzed here in three different dimensions: the Symbolic, the Ontological, and the Epistemic. The first one points towards CERN as place where a cosmological game of probability is played with the help of Monte-Carlo simulations. The second one can be seen in the agonistic infrastructures of competing experimental collaborations. The third dimension unfolds in ludic platforms, such as online Challenges and citizen science games, which contribute to the development of machine learning algorithms, whose function is necessary in order to process the huge amount of data gathered from experimental events. Following Clifford Geertz, CERN itself is characterized as a site of deep play, a concept that contributes to understanding wider social and cultural orders through the analysis of ludic collective phenomena. The article also engages with Peter Galison's idea of the trading zone, proposing to comprehend it in the age of big data as a Playground. Thus the author hopes to contribute to a wider discussion in the historiographical and social study of science and technology, as well as in cultural anthropology, by recognizing the ludic in science as a central element of understanding collaborative knowledge production.

  8. Energy efficiency policies for space heating in EU countries: A panel data analysis for the period 1990–2010

    Highlights: • Space heating demand between 1990 and 2010 modelled using a panel of 14 EU countries. • The impacts of 260 efficiency polices affecting space heating demand are examined. • Regulatory policies found to have had a greater success than financial or informative. • High priority should be given to regulatory policies for space heating energy goals. - Abstract: We present an empirical analysis of the more than 250 space heating-focused energy efficiency policies that have been in force at the EU and national levels in the period 1990–2010. This analysis looks at the EU-14 residential sector (Pre-2004 EU-15, excluding Luxembourg) using a panel data regression analysis on unit consumption of energy for space heating (kWh/m 2 /year). The policies are represented as a regression variable using a semi-quantitative impact estimation obtained from the MURE Policy Database. The impacts of the policies as a whole, and subdivided into financial, regulatory, and informative policies, are examined. The correlation between the actual reductions in demand and the estimated impact of regulatory policies is found to be stronger than the corresponding correlations with the respective impacts of financial policies and informative polices. Together with the well-known market barriers to energy efficiency that exist in the residential sector, these findings suggest that regulatory policy measures be given a high priority in the design of an effective pathway towards the EU-wide goals for space heating energy

    The study attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973-87 and complements an earlier study made in 1973-75 (see CERN Report 75-5). Interviews were carried out in 160 European firms, who supplied estimates of increased sales and cost savings due to CERN contracts. This economic utility totals 3107 million Swiss francs (up to the year 1987), compared to sales to CERN amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973-82 will have generated Economic high technology purchases made in 1973-82 will have generated Economic Utility amounting to about 60% of the overall cost of the Organization during the same period. In 1982, about 75% of the increased turnover due to CERN resulted from sales to markets outside high energy particle physics, for example, railways, shipbuilding, refrigeration, power generation and distribution, and health care. The quantification model used is discussed in detail and some specific cases are presented as examples. The industrial managers interviewed during both studies have confirmed that the forecasts made ten years ago were, on average, accurate. (orig.)

    The CERN Large Hadron Collider is currently being upgraded to operate at a stored beam energy of 680 MJ through the High Luminosity upgrade. The LHC performance is dependent on the functionality of beam collimation systems, essential for safe beam cleaning and machine protection. A dedicated beam experiment at the CERN High Radiation to Materials facility is created under the HRMT-23 experimental campaign. This experiment investigates the behavior of three collimation jaws having novel composite absorbers made of copper diamond, molybdenum carbide graphite, and carbon fiber carbon, experiencing accidental scenarios involving the direct beam impact on the material. Material characterization is imperative for the design, execution, and analysis of such experiments. This paper presents new data and analysis of the thermostructural characteristics of some of the absorber materials commissioned within CERN facilities. In turn, characterized elastic properties are optimized through the development and implementation of a mixed numerical-experimental optimization technique.

    The overall objective of this study is to analyse the effects of using EU ETS auction revenues to stimulate investments in energy savings in three key target sectors, i.e. Households, Tertiary and Industry (including both ETS and non-ETS industrial installations). The scenarios used refer basically to the situation before the recent agreement on the Energy Efficiency Directive (EED) and include (a mixture of) different policy options to enhance energy savings in the target sectors, in particular (1) reducing the ETS cap, (2) introducing an Energy Efficiency Obligation (EEO) for energy suppliers or distributors, and/or (3) using ETS auction revenues to support additional (private) investments in raising energy efficiency. In order to meet this objective a variety of different policy scenarios have been defined and analysed by means of the 'Energy-Environment-Economy Model for Europe (E3ME)'. The study presents and discusses a large variety of scenario modelling results by the year 2020 at the EU27 level. These results refer to, among others, energy savings, GHG emissions, the ETS carbon price, household electricity bills and to changes in some macro- or socio-economic outcomes such as GDP, inflation, employment or international trade. Finally, the study discusses some policy findings and implications, including options to enhance the effectiveness of some EE policies, in particular those having a potential adverse effect on the ETS carbon price.

  14. Big Data Challenges in High Energy Physics Experiments: The ATLAS (CERN) Fast TracKer Approach

    CERN Document Server

    Sotiropoulou, Calliope Louisa; The ATLAS collaboration

    2016-01-01

    We live in the era of “Big Data” problems. Massive amounts of data are produced and captured, data that require significant amounts of filtering to be processed in a realistically useful form. An excellent example of a “Big Data” problem is the data processing flow in High Energy Physics experiments, in our case the ATLAS detector in CERN. In the Large Hadron Collider (LHC) 40 million collisions of bunches of protons take place every second, which is about 15 trillion collisions per year. For the ATLAS detector alone 1 Mbyte of data is produced for every collision or 2000 Tbytes of data per year. Therefore what is needed is a very efficient real-time trigger system to filter the collisions (events) and identify the ones that contain “interesting” physics for processing. One of the upgrades of the ATLAS Trigger system is the Fast TracKer system. The Fast TracKer is a real-time pattern matching machine able to reconstruct the tracks of the particles in the inner silicon detector of the ATLAS experim...

  15. Fossil fuel subsidies and the new EU Climate and Energy Governance Mechanism

    Sartor, Oliver; Spencer, Thomas

    2016-07-01

    There is currently no dedicated process to track the extent of fossil fuel subsidies, nor to ensure that Member States phase them out. This situation is inconsistent with the European Union's stated decarbonization and energy efficiency dimensions under the Energy Union. The EU is therefore in need of an alternative process for tracking and ensuring the phase-out of fossil fuel subsidies by the Member States. The new Energy Union governance mechanism presents an opportunity for creating this alternative. Providing the right price signals is essential part of the policy mix that is needed to achieve Europe's climate policy goals. Phasing out fossil fuel subsidies in the EU is an important part of aligning energy prices with the EU's climate and energy goals. Depending on how they are measured, combined fossil fuel subsidies in the EU range from 39 to over euro 200 billion per annum (European Commission, 2014). They therefore constitute a significant source of incoherence between the EU's climate mitigation and fiscal policies for energy. However, there has recently been mixed progress in addressing fossil fuel subsidies in Europe. For instance, under the Europe 2020 Strategy, Member States had committed to begin developing plans for phasing out fossil fuel subsidies by 2020. Progress on implementing these plans was supposed to be monitored under the European Semester. However, the decision was taken to remove the focus on energy and fossil fuel subsidies from the European Semester in 2015. As yet, no new system for governing the phase-out of fossil fuel subsidies has been advanced, leaving the question of fossil fuel subsidy reform in limbo. The advent of the EU's Energy Union project creates an opportunity for putting the phase-out of fossil fuel subsidies back on track in Europe. This could be done by including requirements for national goal setting on specific kinds of fossil fuel subsidies in a dedicated sub-section of the National Climate and Energy Plans

  16. The role of gas in the external dimension of the EU energy transition

    2013-01-01

    As an economically attractive option for investors, a potential backup source for renewables and the cleanest fossil fuel, natural gas is expected to play an important role in the European transition towards a low-carbon economy by 2050. At a time when European primary energy resources are being depleted and energy demand is growing, the gas import dependency of the EU will continue to grow significantly in the coming years. The EU is thus facing important challenges linked to its gas policy both internally, by attempting to create a competitive, interconnected and well-functioning internal market for gas; and externally, by struggling to develop a coherent and collective external strategy, which would allow it to both diversify and secure its gas supply from abroad. Meanwhile, new sources of unconventional gas could change the world's energy markets with potential consequences for the EU. However, many uncertainties remain regarding their development within the EU. In view of all these challenges, this Policy Paper concludes by laying out concrete recommendations on how the EU could strengthen its gas strategy both internally and externally

  17. High energy hadron-hadron collisions

    Chou, T.T.

    1990-01-01

    Results of a study on high energy collision with the geometrical model are summarized in three parts: (i) the elastic hadron-hadron collision, (ii) the inelastic hadron-hadron collision, and (iii) the e + e - annihilation. The geometrical description of high-energy elastic scattering developed earlier is still in general agreement with experiments at the CERN-S bar ppS energies. A simple one-parameter expression for the blackness of bar pp system has been proposed recently which describes very well all existing data from ISR to S bar ppS energies. The geometrical description has also been extended to include processes of fragmentation and diffraction dissociation and other phenomena. In the past five years, a unified physical picture for multiparticle emission in hadron-hadron and e + e - collisions was developed. It focuses on the idea of the wide range of values for the total angular momentum in hadron-hadron collisions. An extension of this consideration yields a theory for the momentum distribution of the outgoing particles which agrees with bar pp and e + e - collision experiments. The results and conclusions of this theory have been extrapolated to higher energies and yielded many predictions which can be experimentally tested. 37 refs

    A series of Eu(2+) and Tb(3+) singly-doped and co-doped β-Ca3(PO4)2 phosphors have been synthesized via the high-temperature solid-state reaction method. Thermogravimetric (TG) analysis, fourier transform infrared (FT-IR) spectra, X-ray diffraction (XRD) patterns and Rietveld refinements, photoluminescence (PL) spectra including temperature-dependent PL and quantum efficiency, and fluorescence decay lifetimes have been used to characterise the as-prepared samples. Under UV excitation, β-Ca3(PO4)2:Eu(2+) presents a broad emission band centered at 415 nm, which can be decomposed into five symmetrical bands peaking at 390, 408, 421, 435 and 511 nm based on the substitution of five kinds of Ca(2+) sites by Eu(2+) ions. β-Ca3(PO4)2:Tb(3+) shows characteristic emission lines under Tb(3+) 4f-5d transition excitation around 223 nm. In β-Ca3(PO4)2:Eu(2+), Tb(3+) phosphors, similar excitation spectra monitored at 415 and 547 nm have been observed, which illustrates the possibility of energy transfer from Eu(2+) to Tb(3+) ions. The variations in the emission spectra and decay lifetimes further demonstrate the existence of energy transfer from Eu(2+) to Tb(3+) ions under UV excitation. The energy transfer mechanism has been confirmed to be dipole-quadrupole, which can be validated via the agreement of critical distances obtained from the concentration quenching (12.11 Å) and spectrum overlap methods (9.9-13.2 Å). The best quantum efficiency can reach 90% for the β-Ca3(PO4)2:0.01Eu(2+), 0.15Tb(3+) sample under 280 nm excitation. These results show that the developed phosphors may possess potential applications in UV-pumped white light-emitting diodes.

    2003-11-01

    The present study analyses the potential interactions between the EU Emissions Trading Scheme (EU ETS) and some selected energy and climate policy instruments in the Netherlands. These instruments include: (1) The Benchmarking Covenant (BC): a negotiated agreement with energy-intensive industries in order to improve their energy efficiency; (2) The Regulatory Energy Tax (REB): an ecotax (or levy) on the consumption of gas and electricity, including the partial exemption of this ecotax on renewable electricity; (3) The Environmental Quality of Electricity Production (MEP): a feed-in subsidy system for producers of renewable electricity; and (4) The system of Tradable Green Certificates (TGCs): a system of guarantees of origin to promote renewable electricity based on the partial exemption of the REB. A general finding of the present report is that once the EU ETS becomes operational, the effectiveness of all other policies to reduce CO2 emissions of the participating sectors becomes zero. The report explores the specific implications of this general finding for the coexistence of the EU ETS and the selected policy instruments in the Netherlands. It concludes that this coexistence will have a significant impact on the performance of both the EU ETS and the selected instruments in the Netherlands

For the longer term future, a larger detector could provide an increased yield, boosting the neutrino capture rate by up to a factor of ten. Other, more spectacular, option is to shine the CERN neutrino beam towards a detector a long way off. Such a beam is practically unimpeded by matter and could pass right through the earth. Possible contenders for underground target stations equipped with big detectors are the Italian Gran Sasso laboratory, 730 kilometres south, or Superkamiokande, 8750 kilometres away in Japan. Other major ongoing 'flagship' SPS projects include the NA48 experiment to continue precision measurements on the still unexplained phenomenon of CP violation (March 1992, page 7) and the 'Spin Muon Collaboration' looking to probe the spin structure of the proton and the neutron using high energy muon beams (April 1992, page 21). Both these experiments address important physics issues. While SMC is already taking data, NA48 will not become operational until 1995, but should run then for more than three years. Elsewhere at the SPS, ongoing studies include a programme using hyperon beams, and a study of beauty particles (WA92) which would be hampered once the new neutrino programme starts.

    2005-01-01

    In October 2003, the European Union introduced a Directive, which widens the scope of the EU's minimum taxation system from mineral oils to all energy products including coal, natural gas and electricity. It aims at reducing distortions that currently exist between Member States as well as between energy products. In addition, it increases previous minimum tax rates and thus the incentive to use energy more efficiently. The Directive will lead to changes in the energy tax schemes in a number of countries, in particular some southern Member Countries (Greece, Spain, Portugal) and most of the new Member States. In this paper, we analyze the effects of the EU energy tax harmonization with GTAP-E, a computable general equilibrium model. Particular focus is placed on the Eastern European countries, which became new members of the EU in May 2004. We investigate the effects of the tax harmonization on overall economic growth and sectoral development. Special attention is paid to international trade in order to analyze if competitiveness concerns, which have been forwarded in the context of energy taxation are valid. Furthermore, the effect on energy consumption and emissions and thus the contribution to the EU's climate change targets is analyzed

    countries like Russia. The paper concludes that the EU doesn't find it easy to fix their positioning towards these partners. However, many areas of common interest and matching objectives can be identified. In order to understand how this could fit with the Russian side, in a second step, a thorough survey of Russian energy policy and political institutions is conducted. Following an investigation of how the Russian political system including its formal and informal actors defines energy policy interest and positions, it turns out that there are major systematic differences, including very much of a top-down approach and only a few elite groups who exert some informal influence. Today's structure is quite different from the approach during the Yeltsin period. Despite differences between structures and systems, it can be shown that the overall objectives of energy policy and geopolitics are quite clear to understand and that there is a stringent logic behind them. Since it is very high on the Russian agenda to stabilize the country's investment framework, to improve technology transfer and competitiveness of non-resource-based industries, to access new resource bases (such as in the arctic or far abroad) and to attract foreign investors to help addressing the investment gap in the oil and gas production sector, it looks like there is a lot of room for cooperation and matching objectives with the EU side. In a third step then, EU and Russian agendas are compared in order to identify areas of common interest that - in theory - should lead to successful cooperation projects. The paper comes up with several of these. It uses game theory models including a theoretical concept of ''linkage deals'' to develop these thoughts. But as these ''theoretically derived'' models of cooperation can't be observed in practice widely, communicative barriers - leading to a lack of trust between the parties - must form the key obstacle

    2008-01-01

    Over last years, growing concerns related to climate changes and to the necessity of a certain and guarantee energy supply have been generating considerations that will induce to a substantial review of the current European economic and energy system. In such a developing context, governments and economic operators have been giving an important role to bio energy as an instrument to lower polluting emissions, to diversify energy supply and to increase the value of rural areas. This was also emphasized by the European Union through specific measures and incentives. The aim of this paper is to analyse the current agrofuel' role (biodiesel and bio ethanol) in the EU energy policy, considering the problems related to their use as underlined by the lively discussion at international level [it

  13. Energy Revolution. A Sustainable Pathway to a Clean Energy Future for Europe. A European Energy Scenario for EU-25

    Teske, S.; Baker, C.

    2005-09-01

    Greenpeace and the Institute of Technical Thermodynamics, Department of Systems Analysis and Technology Assessment of the German Aerospace Center (DLR),have developed a blueprint for the EU energy supply that shows how Europe can lead the way to a sustainable pathway to a clean energy future. The Greenpeace energy revolution scenario demonstrates that phasing out nuclear power and massively reducing CO2-emissions is possible. The scenario comes close to a fossil fuels phase-out by aiming for a 80% CO2 emissions reduction by 2050.The pathway in this scenario achieves this phase-out in a relatively short time-frame without using technological options (such as 'clean coal') that are ultimately dead ends, deflecting resources from the real solutions offered by renewable energy. Whilst there are many technical options that will allow us to meet short-term EU Kyoto targets (-8% GHG by 2010), these may have limited long-term potential. The Greenpeace Energy Revolution Scenario shows that in the long run, renewable energy will be cheaper than conventional energy sources and reduce EU's dependence from world market prices from imported fossil and nuclear fuels.The rapid growth of renewable energy technologies will lead to a large investment in new technologies.This dynamic market growth will result in a shift of employment opportunities from conventional energy-related industries to new occupational fields in the renewable energy industry. Renewable energy is expected to provide about 700,000 jobs in the field of electricity generation from renewable energy sources by 2010

    Full Text Available This article analyses the issues of EU energy policy in the 1990s-the beginning of the 2000s in order to identify the features of energy supply and energy safety of the Baltic region countries. The research and practical significance of the work lies in the stepwise description of actions taken by EU leaders and EU member states in order to formulate a common European energy policy. The 2004 EU enlargement posed the problem of taking into account the features of energy supply of Eastern European countries and, especially, the Baltic States. The energy industries of Lithuania, Latvia, and Estonia, as well as other Eastern European and CIS countries, are closely related to the energy industry of the Russian Federation. Trying to allow for this circumstance, EU leaders and energy structures took a number of organizational measures aimed, on the one hand, at an increase in energy independence of new members of the EU and, on the other hand, at taking into account the recent trends in the energy market development. The research shows that most of the initiatives do not take into account the perspective and interests of Russia, which has a strong presence in the energy market. The analysis conducted will help the assessment of prospects of further development of the Baltic States' energy industry and its interaction with that of the Russian Federation.

    Energy intensity in Spain has increased since 1990, while the opposite has happened in the EU15. Decomposition analysis of primary energy intensity ratios has been used to identify which are the key sectors driving the Spanish evolution and those responsible for most of the differences with the EU15 energy intensity levels. It is also a useful tool to quantify which countries and economic sectors have had most influence in the EU15 evolution. The analysis shows that the Spanish economic structure is driving the divergence in energy intensity ratios with the EU15, mainly due to strong transport growth, but also because of the increase of activities linked to the construction boom, and the convergence to EU levels of household energy demand. The results can be used to pinpoint successful EU strategies for energy efficiency that could be used to improve the Spanish metric. (author)

    In this work, structural, thermal and optical properties of Eu{sup 3+} doped TeO{sub 2}-La{sub 2}O{sub 3}-TiO{sub 2} glass were investigated. The differential scanning calorimetry (DSC) measurements reveal an important stability factor {Delta}T=143.52 K, which indicates the good thermal and mechanical stabilities of tellurite glass. From the absorption spectrum, the optical band gap was found to be direct with E{sub g}=3.23 eV. The temperature dependences of photoluminescence (PL) properties of Eu-doped and Eu-Tb codoped tellurite glass are investigated. As the temperature increases from 7 to 300 K, both the PL intensity and the PL lifetime relative to the {sup 5}D{sub 2}{yields}{sup 7}F{sub 0} are nearly constant below 230 K and then an enhancement takes place. This anomalous feature is attributed to the thermally activated carrier transfer process from charged intrinsic defects states to Eu{sup 3+} energy levels. By co-doping tellurite glasses with Eu and Tb, a strong Eu{sup 3+} PL enhancement is shown due to excitation transfer from Tb{sup 3+} and intrinsic defects to Eu ions. - Highlights: > TeO{sub 2}-La{sub 2}O{sub 3}-TiO{sub 2} glass doped Eu{sup 3+} with good thermal stability elaborated. > PL evolution of Eu{sup 3+} with temperature shows a non-conventional behavior. > Thermally activated carrier transfer from intrinsic defects states to Eu{sup 3+} shown. > Strong Eu{sup 3+} PL enhancement is shown in Eu-Tb codoped glass.

    This was the fifth of a continuing series of summer studies held at LBL to discuss high energy heavy ion collisions. Recently, a similar meeting has been held on alternate years at GSI (Darmstadt); and, in 1979, we held a meeting at LBL exclusively devoted to ultra-relativistic nuclear collisions. Two new features distinguish this study from earlier meetings in the series. First, the energy range for discussion was broadened by including collisions from about 20 MeV/nucleon to the highest available in the cosmic radiation. The lower range, particularly below 100 MeV/nucleon, will be under intense study in the near future with machines such as the upgraded Bevalac, Michigan State University Superconducting Cyclotron, GANIL in France, and the SC at CERN. Recently, the high energy collision regime has been expanded by the successful operation of the CERN ISR with alpha particles. Second, in addition to an extensive program of invited talks, we decided for the first time to actively solicit contributions. Forty-seven individual items from the conference were prepared separately for the data base

    European Union member states are facing two serious challenges: human-induced climatic changes and oil shortage. Evidence that human-induced global heating is threatening the climatic balance is piling up and the conflicts over the last oil resources are becoming critical. The European Union has neither large oil resources nor foreign-political or military power to conquer additional oil resources. The EU Commission's awareness of these facts is influencing the EU energy and climate policy. Recently EU launched the directive on carbon dioxide emissions trading within certain energy-heavy sectors. The greenhouse gas emission allowance trading directive requires a national ceiling on the allocation of CO 2 quotas for the heavy industry and energy sectors, thus adapting the quantity of quotas to the Kyoto requirements. This requirement can be quite extensive for the sectors affected by the greenhouse gas emission allowance trading directive, if national governments choose to abstain from political intervention in order to reduce release of greenhouse gases in sectors outside the emissions trading, e.g. agriculture, transportation, households, and smaller industry and service. Lack of action in these sectors will require the governments to impose either large burdens or use of national Joint Implementation and Clean Development agreements on the heavy industry and energy sectors outside national borders, thus conflicting with the Kyoto Protocol.

    The EU renewable energy (RES) directive sets a target of increasing the share of renewable energy used in the EU to 20% by 2020. The Norwegian goal for the share of renewable energy in 2020 is 67.5%, an increase from 60.1% in 2005. The Norwegian power production is almost solely based on renewable resources and the possibility to change from fossil power plants to renewable power production is almost non-existing. Therefore other measures have to be taken to fulfil the RES directive. Possible ways for Norway to reach its target for 2020 are analysed with a technology-rich, bottom-up energy system model (TIMES-Norway). This new model is developed with a high time resolution among others to be able to analyse intermittent power production. Model results indicate that the RES target can be achieved with a diversity of options including investments in hydropower, wind power, high-voltage power lines for export, various heat pump technologies, energy efficiency measures and increased use of biodiesel in the transportation sector. Hence, it is optimal to invest in a portfolio of technology choices in order to satisfy the RES directive, and not one single technology in one energy sector. - Highlights: • A new technology-rich, bottom-up energy system model is developed for Norway. • Possible ways for Norway to reach its renewable energy target for 2020 is analysed. • Results show that the renewable target can be achieved with a diversity of options. • The green certificate market contributes to increased investments in wind power

    SrF 2 :Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF 2 nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu 2+ and Eu 3+ . At low Eu concentrations the emission from Eu 2+ centered at 416 nm was more dominant. While the narrow band of Eu 3+ emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu 2+ and Eu 3+ valance states. The presence of Eu 2+ and Eu 3+ in the system largely enhanced the response of the Eu 3+ under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu 2+ rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu 2+ doped SrF 2 samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF 2 : Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu 3+ UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu 2+ to Eu 3+ is dominant

    CERN's long and distinguished neutrino tradition began in 1958 at the then new 500 MeV synchrocyclotron (SC) with the first observation of the decay of a charged pion into an electron and a neutrino. At that time, the first ideas on the special (vector/axial vector) structure of the weak interactions had been put forward by Feynman and Gell-Mann and by Marshak and Sudarshan, but the continual non-observation of that charged pion decay was holding up progress. This decay is only one part in ten thousand, and is masked by the dominant muon-neutrino channel. A special telescope was built to pick up the high energy electrons from the pion decay. In 1962 came another SC neutrino success, with the first measurement of the decay of a charged pion into a neutral one, with emission of an electron and a neutrino. Meanwhile the main thrust of CERN's neutrino effort was taking shape at the PS. By the close of 1960, CERN had decided to attack neutrino physics using several detectors - a 1m heavy liquid bubble chamber from Andre Lagarrigue's team in Paris, a CERN 1 m heavy liquid bubble chamber, and a hybrid chamber/counter from a group led by Helmut Faissner

    The EU Green Paper on energy efficiency calls for action to decrease energy use and thus achieve increased competitiveness, fulfil the environmental targets and increase security of supply. In this comment, we examine the role the EU Commission suggest that energy efficiency, and policies supporting energy efficiency, takes. The policies and the suggestions are qualitatively elaborated upon in the light of the goal of a common European electricity market. We suggest that the rationales for the energy efficiency measures are weak, and that the suggested goals of increased competitiveness, environmental targets, and security of supply are best reached with the direct measures especially designed for each goal. Some of the energy efficiency measures may counter-act other direct policies. Further, The Green Paper measures may prove detrimental to the European Electricity market insofar as the policies suggested could lead to a policy fatigue among the electricity consumers

  16. Methodological proposal for territorial distribution of the percentage reduction in gross inland energy consumption according to the EU energy policy strategic goal

    2010-01-01

    A 20% reduction in the consumption of energy is one of the main goals of the European Union's (EU) 20/20/20 Energy Strategy. But the uniform application of this overall goal to all of the countries is neither fair nor equitable, as it does not take into consideration the characteristics of the energy system in each Member State. This article therefore proposes a nonlinear distribution methodology with objective, dynamic goals for reducing gross inland energy consumption, according to the context and characteristics of each member state. We hope it will open discussion on how these overall goals can be weighted. Then we analyse the situation of the energy indicators related to energy efficiency in the reference year (2005) used by the EU for reaching its goal of reducing the gross inland consumption by 20% by 2020, and its progress from 1996 to 2007. Finally, the methodology proposed is applied to the year 2020 on the NUTS0 territorial level, that is, to members of the EU, according to the EUROSTAT Nomenclature of Territorial Units for Statistics (NUTS). Weighting is done based on energy intensity, per capita gross inland consumption and per capita energy intensity in two scenarios, the EU-15 and EU-27.

    What considerations must be addressed to ensure that efforts to achieve the EU's new 2030 emissions and renewables targets are compatible with the other energy goals of the EU and its member states: energy security, and energy affordability? How should these other energy goals be addressed when pursuing energy efficiency improvements, upgrading electricity systems to handle different renewable energy sources, and developing policies to reduce overall CO2 emissions? Markets have been defined as being central to achieving all of Europe's energy goals - both the creation of an EU internal energy market and the use of the Emissions Trading System (ETS) to allow a market for managing a portion of the continent's greenhouse gas emissions. But once these markets are in place and operational, there will still be great variances among the goals, instruments, and level of market integration available for the different countries and regions of Europe. Choosing the most cost effective mechanisms for pursuing the new goals will require effective use of the flexibility that is available - an improved ETS, tradable national targets for non-ETS emissions, and a rapidly widening array of cost-effective renewable energy options. Sufficient use of this flexibility should facilitate the flow of energy investments toward energy system improvements where there is low-hanging fruit - anywhere in the continent - without requiring that local or continental energy security goals be sacrificed.

    Today's society relies heavily on fossil fuels as a main energy source. Global energy demand increase, energy security and climate change are the main drivers of the transition towards alternative energy sources. This paper analyses algal biodiesel production for the EU road transportation and compares it to the fossil fuels and 1st generation biofuels. A cost-effectiveness analysis was used to aggregate private and external costs and derive the social cost of each fuel. The following externalities were internalized: emissions (GHG and non-GHG), food prices impact, pesticides/fertilizers use and security of supply. Currently the social cost of producing algal biodiesel at 52.3 EUR GJ -1 is higher than rapeseed biodiesel (36.0 EUR GJ -1 ) and fossil fuels (15.8 EUR GJ -1 ). Biotechnology development, high crude oil prices and high carbon value are the key features of the scenario where algal biodiesel outcompetes all other fuels. A substantial investment into the biotechnology sector and comprehensive environmental research and policy are required to make that scenario a reality. (author)

    The Large Hadron Collider (LHC) at the European Organization for Nuclear Research (CERN) near Geneva, Switzerland, is now the highest energy accelerator in the world, colliding protons with protons. On July 4, 2012, the two general-purpose experiments, ATLAS and the Compact Muon Solenoid (CMS) experiment, announced the observation of a particle consistent with the world’s most sought-after particle, the Higgs boson, at a mass of about 125 GeV (approximately 125 times the mass of the proton). The Higgs boson is the final missing ingredient of the standard model, in which it is needed to allow most other particles to acquire mass through the mechanism of electroweak symmetry breaking. We are members of the team in the CMS experiment that found evidence for the Higgs boson through its decay to two photons, the most sensitive channel at the LHC. We are proposing to carry out studies to determine whether the new particle has the properties expected for the standard model Higgs boson or whether it is something else. The new particle can still carry out its role in electroweak symmetry breaking but have other properties as well. Most theorists think that a single standard model Higgs boson cannot be the complete solution – there are other particles needed to answer some of the remaining questions, such as the hierarchy problem. The particle that has been observed could be one of several Higgs bosons, for example, or it could be composite. One model of physics beyond the standard model is supersymmetry, in which every ordinary particle has a superpartner with opposite spin properties. In supersymmetric models, there must be at least five Higgs bosons. In the most popular versions of supersymmetry, the lightest supersymmetric particle does not decay and is a candidate for dark matter. This proposal covers the period from June 1, 2013, to March 31, 2016. During this period the LHC will finally reach its design energy, almost twice the energy at which it now runs. We will

    The SET-Plan established a strategy to use Research and Innovation (R and I) to green the EU energy sector while ensuring a secure supply and increasing EU competitiveness. The strategy sets clear objectives and programming plans and takes stock of existing initiatives in the energy sector, fosters a cooperative approach to R and I, introduces a high-level steering group (the SET-Plan Steering Group) to monitor progress, creates a dedicated information system (the SETIS) to fill the void in policy information and produces estimates of financial needs over the programming period. In this respect, the SET-Plan could serve as a blueprint for R and I strategies to tackle other societal challenges. To be effective, such strategies should further clarify the hierarchy of existing objectives and instruments, introduce specific instruments to pull the demand of new technologies, strengthen links with education and training policies and formalize links with the governance structures of existing initiatives. - Highlights: > This paper assesses the impact of the SET-Plan on EU renewable energy policy. > We analyze the degree of complementarity and duplication with existing initiatives. > We discuss the role of a new system of indicators (SETIS). > The analysis of financing reveals the existence of sizeable shortfalls. > Lessons for future similar initiatives are sketched.

    Highlights: • A series of color-tunable LuBO{sub 3}: Ce{sup 3+}/Tb{sup 3+}/Eu{sup 3+} phosphors were synthesized. • Phosphors exhibit strong blue/green/red emission under UV excitation. • The reason of high Tb{sup 3+} content required for Ce{sup 3+} → Tb{sup 3+} → Eu{sup 3+} energy transfer is unveiled. • Green and red LED prototypes were fabricated and characterized. - Abstract: A series of LuBO{sub 3}: Ce{sup 3+}/Tb{sup 3+}/Eu{sup 3+} phosphors were synthesized via solid state reaction. The Ce{sup 3+}/Tb{sup 3+} co-doped and Ce{sup 3+}/Tb{sup 3+}/Eu{sup 3+} tri-doped phosphors absorb near UV light through 4f-5d transitions of Ce{sup 3+}, followed by sensitized Tb{sup 3+} green and Eu{sup 3+} red emission. Decay curves investigations for samples with various Tb{sup 3+} and Eu{sup 3+} contents reveal the occurrence of Ce{sup 3+} → Tb{sup 3+} → Eu{sup 3+} energy transfer. It is found that due to relative low Tb{sup 3+} → Eu{sup 3+} energy transfer rate, a high Tb{sup 3+} content (>40%) is required for efficient Ce{sup 3+} → Tb{sup 3+} → Eu{sup 3+} energy transfer. Emission color of LuBO{sub 3}: Ce{sup 3+}, Tb{sup 3+}, Eu{sup 3+} varies from blue through green to red with Ce{sup 3+}/Tb{sup 3+}/Eu{sup 3+} ratio. The quantum efficiency of LuBO{sub 3}: Ce{sup 3+}, Tb{sup 3+} green phosphor and LuBO{sub 3}: Ce{sup 3+}, Tb{sup 3+}, Eu{sup 3+} red phosphor is 50% and 30%, respectively. Green and red LED prototypes were fabricated. The results show that the obtained phosphors are potential candidates as down-converted phosphors for NUV LEDs.

    Energy security and gas supply have become issues of central concern for the European Union as reserves in the North Sea are dwindling. Russia is offering to replace the North Sea supplies in the future, but the EU should be aware that Moscow will not be able to fully meet Europe's demand in the future. Russia will remain a significant supplier, but the EU needs to look for other possible sources of gas supply in Northern Africa, in the Caspian Sea region, in the Barents Sea, and in the Persian Gulf. Diversification is the best strategy for enhancing European energy security. (author)

    In adopting the so-called Third Single Energy Market Package on September 9, 2007, the European Commission has initiated a comprehensive reform of the single energy market. The main item of the package is the separation of generation and supply from the transmission grids and transport networks in the electricity and gas sectors (ownership unbundling), an approach favored by the Commission. On the other hand, the Commission wants to advance protection of the European market in case firms from third countries, to the extent in which they do not comply with the EU unbundling requirements, would want to assume control over an EU grid or network. The key points of the package are presented. The legal and entrepreneurial ramifications are discussed, for instance, under the aspect of protection of ownership, and concrete as well as potential concerns about ownership unbundling are voiced.

    The origin of the ultra high energy cosmic rays (UHECR) with energies above E > 10 17 eV, is still unknown. The discovery of their sources will reveal the engines of the most energetic astrophysical accelerators in the universe. This is a written version of a series of lectures devoted to UHECR at the 2013 CERN-Latin-American School of High-Energy Physics. We present anintroduction to acceleration mechanisms of charged particles to the highest energies in astrophysical objects, their propagation from the sources to Earth, and the experimental techniques for their detection. We also discuss some of the relevant observational results from Telescope Array and Pierre Auger Observatory. These experiments deal with particle interactions at energies orders of magnitude higher than achieved in terrestrial accelerators.

    Sm 3+ , Eu 3+ , and Sm 3+ –Eu 3+ doped Ca 2 PO 4 Cl phosphors are synthesized by a solid-state method. Ca 2 PO 4 Cl:Sm 3+ can produce red emission under the 400 nm radiation excitation, and the emission peak is located at 601 nm, which is assigned to the 4 G 5/2 → 6 H 7/2 transition of Sm 3+ . Ca 2 PO 4 Cl:Eu 3+ can create red emission under the 392 nm radiation excitation, and the strongest peak is located at 620 nm, which is attributed to the 5 D 0 → 7 F 2 transition of Eu 3+ . The energy transfer from Sm 3+ to Eu 3+ in Ca 2 PO 4 Cl has been validated and the critical distance (R c ) of Sm 3+ to Eu 3+ in Ca 2 PO 4 Cl is calculated to be 1.14 nm. With increasing Eu 3+ doping concentration, the energy transfer efficiency (Sm 3+ →Eu 3+ ) gradually increases to 53.7%. The luminescence property of Ca 2 PO 4 Cl:Sm 3+ , Eu 3+ can be tuned by properly tuning the relative ratio of Sm 3+ –Eu 3+ , and the emission intensity of Ca 2 PO 4 Cl:Eu 3+ can be greatly enhanced by codoped Sm 3+ . - Highlights: • Ca 2 PO 4 Cl:Sm 3+ , Eu 3+ can produce red emission under the 400 nm radiation excitation. • The energy transfer from Sm 3+ to Eu 3+ in Ca 2 PO 4 Cl has been validated. • The critical distance of Sm 3+ to Eu 3+ in Ca 2 PO 4 Cl is calculated to be 1.14 nm

    2009-01-01

    The European Union's EU-Africa Energy Partnership, with respect to its emphasis on transport fuels, aims to ensure that Member States can fulfil agreed upon commitments to sustainable energy via the importation of biomass grown in sub-Saharan Africa. This policy aims to reduce the dependence of developing sub-Saharan nations on fossil-fuels, while ensuring the global proliferation of alternative transport energy generation as a means to combat climate change. Though the policy seems equitable in theory, and indeed mutually beneficial, several important issues arise. The paper examines the EU-Africa Energy Policy in the context of biofuels in particular, with a view to identifying potential flaws and imbalances and making policy recommendations. Aside from establishing critical uncertainties, the study adduces environmental science, historical comparanda and economic theory in order to assess the various threats associated with aspects of the policy, especially in light of previous policies that have stifled the development of sub-Saharan economies. In addition, the paper has substantial relevance to developing and newly industrialized nations in Asia and South America also seeking to invest in biomass cultivation and production.

    2014-01-01

    Costs and Benefits to EU Member States of 2030 Climate and Energy Targets is based on analyses using the POLES-Enerdata model and presents an overview of the main European energy and climate policies: reduction of CO_2 emissions, development of renewable energies, and promotion of energy efficiency. The report looks forward to 2030 and beyond to evaluate possible targets and the goal of maintaining global temperature rise to 2 deg. C. This publication was produced by Enerdata's Global Energy Forecasting team, including the modelling and scenario analysis, within the framework of an external service contract to the UK's Department of Energy and Climate Change. This project looks ahead to 2030. To do this, scenarios were developed using the POLES-Enerdata model, a world energy-economy model that fully describes the energy system and associated GHG emissions. This report analyses the costs and benefits to all EU Member States under different scenarios of the level and type of EU targets defined within a 2030 climate and energy framework. Scenarios include progressively more stringent GHG targets in 2030 (40%, 50%, and 60% reductions compared to 1990), alternative assumptions on access to international credits (0%, 5% and 10% of 1990 emissions), the addition of RES burden shares by Member State, accelerated CCS commercial availability and reduced renewables learning rates. These are the sensitivities commissioned as part of this report; however, they are not a comprehensive range covering all possible outcomes that could arise in reality. What are the costs and benefits to Member States under different scenarios of the level and type of EU targets? The analysis assesses the benefits of different scenarios to improved air quality and health, diversity of energy supply, and reduced costs of meeting longer term emission reduction targets (notably the EU's commitment to reduce emissions by 80-95% by 2050). Relying on more low-carbon, domestic, or diversified sources of

    2002-01-01

    The SPL (Superconducting Proton Linac) study at CERN foresees the construction of a 2.2 GeV linac as a high beam-power driver for applications such as a second-generation radioactive ion beam facility or a neutrino superbeam. At the same time such a high-performance injector would both modernize and improve the LHC injection chain. The 120 MeV normal-conducting section of the SPL could be used directly in a preliminary stage for H- charge-exchange injection into the PS Booster. This would increase the proton flux to the CERN experiments while also improving the quality and reliability of the beams for the LHC. The 120 MeV linac consists of a front-end, a conventional Drift Tube Linac (DTL) to 40 MeV and a Cell Coupled Drift Tube Linac (CCDTL) to the full energy. All the RF structures will operate at 352 MHz, using klystrons and RF equipment recovered from the LEP collider. This paper concentrates on the design of the 3 to 120 MeV section. It introduces the design criteria for high-stability beam optics and th...

    De Jong, Jacques [Clingendael International Energy Programme CIEP, Den Haag (Netherlands)

    2008-02-15

    The liberalisation of EU energy markets has been a key objective of EU policy makers for many years. Proposals issuing from Brussels have met with both applause and resistance from many business and political circles. Ever since the project of a 'single European market for gas and electricity' began in the early 1990s, the debate has been alternatingly dominated by rational and emotional arguments, resulting in more or less effective compromises. In this new CIEP Briefing Paper the author takes a thorough look at energy policy in the European Union. He author offers a detailed and thoughtful expose of the current discussions on European electricity and gas markets, and offers key suggestions for fruitful discussions on how to secure competitive EU markets with a reliable external security of (gas) supply.

    1993-01-01

    With the gold beam operation at the Brookhaven AGS started in 1992, and with the lead beam operation at the CERN SPS planned for 1994--1995, investigation of high nucleon density states through high energy heavy ion collisions is becoming a reality. In addition, the Relativistic Heavy Ion Collider (RHIC) at BNL, which is dedicated to the study of ultra-high energy heavy ion collisions, is under construction with a target completion date in 1997. There also is a plan to run the proposed CERN LHC for a few months a year for the heavy ion program. These colliders should provide opportunities to extend our knowledge of nuclear matter to the extraordinary states of extreme high temperature and high density, thus opening the way to the creation and study of quark-gluon plasma. The lattice gauge calculation based on the theory of strong interactions (QCD) predicts that, at such states, quarks and gluons are deconfined from individual nucleons and form a hot plasma. In this paper, the status of heavy ion stationary target programs at the BNL AGS and the CERN SPS, the progress of RHIC construction, and heavy ion research potential at LHC will be presented. The status of the CERN LHC will be covered elsewhere in these Proceedings

  3. EU energy-intensive industries and emissions trading: losers becoming winners?

    Energy Technology Data Exchange (ETDEWEB)

    Wettestad, Joergen

    2008-11-15

    The EU Emissions Trading System (ETS) initially treated power producers and energy-intensive industries similarly, despite clear structural differences between these industries regarding pass through of costs and vulnerability to global competition. Hence, the energy-intensive industries could be seen as losing out in the internal distribution. In the January 2008 proposal for a reformed ETS post-2012, a differentiated system was proposed where the energy-intensive industries come out relatively much better. What is the explanation for the change taking place? Although power producers still have a dominant position in the system, the increasing consensus about windfall profits has weakened their standing. Conversely, the energy-intensive industries have become better organised and more active. This balance shift is first and foremost noticeable in several important EU-level stake holder consultation processes. Energy-intensive industries have, however, also successfully utilised the national pathway to exert influence on Brussels policy-making. Finally, growing fear of lax global climate policies and related carbon leakage has strengthened the case of these industries further. The latter dimension indicates that although energy-intensive industries have managed to reduce internal distribution anomalies, external challenges remain. (author). 9 refs

    In addition to public policies aimed at improving the energy efficiency of buildings, EU authorities have also promoted the use of Renewable Energy Sources for heating and cooling uses (RES H and C). This paper analyses the main policy measures implemented in EU-27 countries up to 2009: i.e. subsidies, tax incentives, financial support and feed-in tariffs. Twenty-three Member States (MSs) have developed some of these policy measures. The most widespread measure is the subsidy (22 MSs have implemented these) because from a political point of view, subsidies provide a straightforward approach to promote the use of RES H and C. Secondly, tax incentives have been used for reducing investment costs and making renewable energy profitable. Thirdly, financial incentives and feed-in tariffs have been used sparingly. While financial incentives might be used more extensively for promoting RES H and C if they are accompanied by other policy measures, feed-in tariffs are not likely to be implemented significantly in the future because this measure is not designed for household heat producers. - Highlights: → Main EU policies to reduce energy consumption are focused on buildings' efficiency. → Alternative incentives to promote the use of RES H and C in EU-27 are now studied. → Subsidies are the most widespread measure. → Tax incentives are used for reducing investment costs and making RES profitable. → Financial incentives and feed-in tariffs have been used sparingly.

    Security of energy supply is a cornerstone of European energy policy. It receives specific mention both in the Constitution Treaty and in the Lisbon Treaty. Of course, energy and energy-generated revenues are vital for Russia as well. It is a common understanding that Russia and the EU are extremely interdependent in terms of energy. On the one hand, Russia is the strategic energy supplier to the EU as a whole; for some member states Russian supplies represent the only source of the external energy flows. On the other hand, the revenues generated from the west-bound supplies of oil and gas constitute a significant share of the overall export income and of the budget of Russian Federation. Taking the interdependency as a point of departure the present article answers the following questions: What are the differences and the similarities in the European and the Russian approaches towards security of energy supply? Is their understanding of energy security so different? What are the current legal instruments guiding interaction in this sphere? What are the actual trends that could give some indication of how the situation may develop in the future? - While the concepts of 'security of energy supplies' or of 'energy security' are theoretical in nature, the ways the concepts are understood and the legal framework for them directly influences the way they are applied in practice.

    Charitonidis, N; Efthymiopoulos, I

    2014-01-01

    HiRadMat (High Radiation to Materials), constructed in 2011, is a facility at CERN designed to provide high‐intensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies (e.g. vacuum windows, high power beam targets, collimators…) can be tested. The facility uses a 440 GeV proton beam extracted from the CERN SPS with a pulse length of up to 7.2 us, and with a maximum pulse energy of 3.4 MJ (3xE13 proton/pulse). In addition to protons, ion beams with energy of 440 GeV/charge and total pulse energy of 21 kJ can be provided. The beam parameters can be tuned to match the needs of each experiment. HiRadMat is not an irradiation facility where large doses on equipment can be accumulated. It is rather a test area designed to perform single pulse experiments to evaluate the effect of high‐intensity pulsed beams on materials or accelerator component assemblies in a controlled environment. The fa‐ cility is designed for a maximum of 1E16 protons per year, dist...

    In March 2007, the European heads of state and government agreed at their European Council upon a 20% greenhouse gas (GHG) emission reduction target compared to 1990-levels and a 20% share of renewable energies in EU's final energy consumption by 2020. To implement these commitments, the European Commission prepared a set of legislative proposals - the so-called 'Climate and Energy Package' - which was jointly endorsed by the European Parliament and the European Council in Dec. 2008 and formally adopted in April 2009. This new policy will run from 2013 to 2020. Hence, the reinforcement of European Union's energy and climate policy in the decade to come was decided and prepared in 2007-2008. But in the meantime, the economic conditions worldwide and in Europe more particularly have radically changed compared to what they were in 2007-2008 when the package was designed. The European Commission has drafted its proposals for the Climate and Energy Package following the outcomes of an impact assessment based on several modeling tools. These modeling tools were not used for determining the 20-20 in 2020 targets or checking their feasibility - those were political targets decided by the European Council in March 2007. The models served to assess the effects and costs of different allocation methodologies. In its drafting proposals, the Commission projected an annual Gross Domestic Product (GDP) growth of 2.2% on average until 2010 in the EU and a 2.4% growth between 2010 and 2020. But because of the economic crisis, the European Union has on the contrary seen a sharp fall of its GDP in 2009: according to the latest forecast by the International Monetary Fund (IMF), which is quite similar with forecasts from other organizations, such as the European Commission or the OECD, the EU-27 should see its GDP decrease by 4.2% in 2009. Opinions are divided when it comes to the question of when and how fast the economy recovers. The IMF has predicted a rather flat GDP growth in 2010

    A series of color-tunable blue–green emitting Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ phosphors were prepared by a high temperature solid-state reaction. Their luminescence properties reveal that there is an efficient energy transfer from Eu 2+ to Tb 3+ ions via a dipole–quadrupole mechanism where Eu 2+ ions exhibit a strong excitation band in near ultraviolet (UV) region, matching well with the dominant emission band of near UV (350–420 nm) LED chips, and Eu 2+ and Tb 3+ ions can give characteristic blue and green emission light. The varied color of the phosphors from blue to green can be achieved by properly tuning the relative ratio of Eu 2+ to Tb 3+ dopant through the energy transfer from Eu 2+ to Tb 3+ ions. Thermal quenching luminescence results reveal that Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ exhibits good thermal stability. These results demonstrate that Tb 3+ ion with low 4f–4f absorption efficiency in near UV region can play the role of an activator in narrow green-emitting phosphor through efficient energy feeding by allowing 4f–5d absorption of Eu 2+ with high oscillator strength. The present Eu 2+ –Tb 3+ codoped Na 2 Ca 4 (PO 4 ) 3 F phosphor will have potential application for the near UV white LEDs. - Highlights: ► Color-tunable blue–green Na 2 Ca 4 (PO 4 ) 3 F:Eu 2+ ,Tb 3+ phosphors were prepared. ► Eu 2+ –Tb 3+ energy transfer process and mechanism discussed. ► Thermal quenching properties of blue and green phosphors were studied.

    The EuSe nanoparticles were prepared by the thermal reduction of Europium nitrate with new organic selenium compound, tetraphenylphosphonium diphenylphosphinediselenide (PPh 4 )(Se 2 P(C 6 H 5 ) 2 ), for the first time. EuSe nanoparticles were identified by the X-ray diffraction (XRD), the transmission electron microscope (TEM) and the energy dispersive X-ray spectroscopy (EDX) measurements. The average size of the EuSe nanoparticles was found to be 19 nm. The energy gap in EuSe nanoparticles of 19 nm was estimated by edge of absorption band, giving the energy gap of 1.86 eV

    SrF{sub 2}:Eu nanophosphors were successfully synthesized by the hydrothermal method. The structure of the nanophosphors was investigated with x-ray diffraction. The average crystallite size calculated using the Scherrer equation was in the range of 7.0 nm. The photoluminescence of Eu doped as-prepared SrF{sub 2} nanophosphors were studied using different excitation sources. The samples showed emission from both the Eu oxidation states, Eu{sup 2+} and Eu{sup 3+}. At low Eu concentrations the emission from Eu{sup 2+} centered at 416 nm was more dominant. While the narrow band of Eu{sup 3+} emission intensity increased with an increase in the Eu concentration. High resolution x-ray photoelectron spectroscopy results indicated that the Eu was indeed in both Eu{sup 2+} and Eu{sup 3+} valance states. The presence of Eu{sup 2+} and Eu{sup 3+} in the system largely enhanced the response of the Eu{sup 3+} under ultraviolet excitation. The time of flight-secondary ion mass spectrometry results suggested that the energy transfer between two ions was likely to occur. The relative photoluminescence intensity of the Eu{sup 2+} rapidly decreased with an increasing laser beam irradiating time. This result would make the current Eu{sup 2+} doped SrF{sub 2} samples unsuitable candidates for several applications, such as white light-emitting diodes and wavelength conversion films for silicon photovoltaic cells. - Highlights: • SrF{sub 2}: Eu nanophosphors were successfully synthesised (hydrothermal technique). • PL and XPS results showed enhanced absorption response of Eu{sup 3+} UV excitation. • Eu concentrations more than 5 mol% improved fluorescence emission. • TOF-SIMS results suggested that the energy transfer from Eu{sup 2+} to Eu{sup 3+} is dominant.

    In relation with coping with global environmental problems in recent years, needs are increasing more than ever for enhancing fossil energy utilization rates, developing and expanding utilization of petroleum substituting energies that can substitute fossil energies. Since Japan is particularly a large energy consuming country, and cannot escape from depending on import for the majority of its energy resources, it is an urgent issue to enhance the energy utilization efficiency and further promote development and utilization of new energies. To do this, it is indispensable to exchange such item of information as identification of actual status in other countries of handling the petroleum substituting energies. Taking up geothermal energy, fiscal 1998 invited four experts from EU countries. Visits were made for about two weeks on Japanese research institutes and business enterprises related to geothermal energy, and opinions and information were exchanged. A seminar was held on the final day, where the EU experts have made presentations on the current status and future prospects on geothermal research and development in EU. Greatly valuable suggestions were given for the Japan's future geothermal research and development. (NEDO)

  2. High-Precision Measurement of Eu/Eu* in Geological Glasses via LA-ICP-MS Analysis

    2014-01-01

    Elemental fractionation during laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) analysis has been historically documented between refractory and volatile elements. In this work, however, we observed fractionation between light rare earth elements (LREEs) and heavy rare earth elements (HREEs) when using ablation strategies involving large spot sizes (greater than 100 millimeters) and line scanning mode. In addition: (1) ion yields decrease when using spot sizes above 100 millimeters; (2) (Eu/Eu*)(sub raw) (i.e. Europium anomaly) positively correlates with carrier gas (He) flow rate, which provides control over the particle size distribution of the aerosol reaching the ICP; (3) (Eu/Eu*)(sub raw) shows a positive correlation with spot size, and (4) the changes in REE signal intensity, induced by the He flow rate change, roughly correlate with REE condensation temperatures. The REE fractionation is likely driven by the slight but significant difference in their condensation temperatures. Large particles may not be completely dissociated in the ICP and result in preferential evaporation of the less refractory LREEs and thus non-stoichiometric particle-ion conversion. This mechanism may also be responsible for Sm-Eu-Gd fractionation as Eu is less refractory than Sm and Gd. The extent of fractionation depends upon the particle size distribution of the aerosol, which in turn is influenced by the laser parameters and matrix. Ablation pits and lines defined by low aspect ratios produce a higher proportion of large particles than high aspect ratio ablation, as confirmed by measurements of particle size distribution in the laser induced aerosol. Therefore, low aspect ratio ablation introduces particles that cannot be decomposed and/or atomized by the ICP and thus results in exacerbated elemental fractionation. Accurate quantification of REE concentrations and Eu/Eu* requires reduction of large particle production during laser ablation. For the reference

  4. Markets for energy efficiency: Exploring the implications of an EU-wide 'Tradable White Certificate' scheme

    International Nuclear Information System (INIS)

    Mundaca, Luis

    2008-01-01

    Recent developments in European energy policy reveal an increasing interest in implementing the so-called 'Tradable White Certificate' (TWC) schemes to improve energy efficiency. Based on three evaluation criteria (cost-effectiveness, environmental effectiveness and distributional equity) this paper analyses the implications of implementing a European-wide TWC scheme targeting the household and commercial sectors. Using a bottom-up model, quantitative results show significant cost-effective potentials for improvements (ca. 1400 TWh in cumulative energy savings by 2020), with the household sector, gas and space heating representing most of the TWC supply in terms of eligible sector, fuel and energy service demand, respectively. If a single market price of negative externalities is considered, a societal cost-effective potential of energy savings above 30% (compared to the baseline) is observed. In environmental terms, the resulting greenhouse gas emission reductions are around 200 Mt CO 2-eq by 2010, representing nearly 60% of the EU-Kyoto-target. From the qualitative perspective, several embedded ancillary benefits are identified (e.g. employment generation, improved comfort level, reduced 'fuel poverty', security of energy supply). Whereas an EU-wide TWC increases liquidity and reduces the risks of market power, autarky compliance strategies may be expected in order to capture co-benefits nationally. Cross subsidies could occur due to investment recovery mechanisms and there is a risk that effects may be regressive for low-income households. Assumptions undertaken by the modelling approach strongly indicate that high effectiveness of other policy instruments is needed for an EU-wide TWC scheme to be cost-effective

    Following the tradition, the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics are presented under a common header, they are: Department of Particle Theory (Dept 5); Department of Leptonic Interactions (Dept 11); Department of Hadron Structure (Dept 12); Department of High Energy Nuclear Interactions (Dept 13); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). The research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e + e - interactions and tests of the Standard Model (also radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY) is also presented. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy (UMM). This location, close to the Jagiellonian University (JU), facilitates the collaboration with the latter and with the UMM. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of the activities is teaching and training students from the academic community in Cracow. Joint research, teaching and academic training in the high energy physics are carried out within the M. Miesowicz

    The European Union long-term strategy for security of energy supply and its commitment to curb climate change led to the adoption of a series of Strategy Papers and EU Directives. In all these, it is clearly stated that climate change is a long-term challenge for the international community and that the commitments made in the Kyoto Protocol can only be a first step. The promotion of renewable energies is a most important element of this process. It regards industry, jobs and foreign trade balance as well, generating benefit to social sustainability. Photovoltaic is a key technology with the potential not only to serve the needs in energy supply of tomorrow in a sustainable way, but already today, it can improve security and stability of electricity services at peak times, due to its decentralized nature. This paper gives an update on the EU and National legislation in place to promote the implementation of photovoltaic. (authors)

Since several years, fast single bunch vertical instability at transition energy has been observed with the high intensity bunch serving the neu-tron Time-of-Flight facility (n-ToF). In order to better understand the instability mechanism, a dedicated meas-urement campaign took place. The results were compared with macro-particle simulations with PyHEADTAIL based on the new impedance model developed for the PS. Instability threshold and growth rate for different longitu-dinal emittances and beam intensities were studied.

    Wind energy is often said to have positive effects on employment, but few studies have systematically dealt with this matter. This article presents estimates of direct wind energy employment in all EU countries, gathered for the first time. By using a thematic survey, the authors have been able to analyse aspects such as gender distribution, company profiles and the shortage of skilled workers reported by wind energy companies. The outcomes show that wind energy deployment creates a significant number of jobs (over 104,000 in 2008), and does so at a time when other energy sectors are shrinking. There is a clear relationship between MW installed and number of jobs, but the use of a single EU job/MW ratio is not feasible, due to differences in the export/import capacity. Wind turbine manufacturers-including major sub-components-are responsible for the lion's share of the jobs, and there is a marked prevalence of males in the workforce. The scarcity of specialist roles-project managers, engineers and O and M technicians-is not likely to be solved unless a series of educational, mobility and dissemination measures are put into practice.

  16. Novel red phosphors KBaEu(XO4)3 (X = Mo, W) show high color purity and high thermostability from a disordered chained structure.

    Two novel red phosphors KBaEu(XO 4 ) 3 (X = Mo, W) have been synthesized by high-temperature solid-state reactions and the crystal structures were determined for the first time. Single-crystal X-ray diffraction data reveal that their space groups are C2/c. The crystalline structure is constituted of K/BaO 8 distorted square antiprisms and distorted EuO 8 polyhedra which form chains lying along the c-axis and two kinds of distorted XO 4 tetrahedra. This high disorder of K/Ba which might lower the crystal field symmetry around Eu 3+ results in the high purity of red emission around 615 nm originating from 5 D 0 → 7 F 2 transition under near-ultraviolet (NUV) excitation. With increasing temperature, the luminescence of KBaEu(XO 4 ) 3 (X = Mo, W) phosphors decreases almost linearly with subtle alteration for the CIE coordinate. As the temperature reaches 550 K, the red emission intensity decreases to 37.3% and 50.7% of that at 300 K for KBaEu(MoO 4 ) 3 and KBaEu(WO 4 ) 3 , respectively. The analysis of the decay curves of the 5 D 0 → 7 F 2 emission at variable temperatures indicates the weak cross relaxation and non-radiative energy transfer between Eu 3+ ions. These results demonstrate that the investigated phosphors are attractive for application in high power NUV excited white LEDs.

    Graphical abstract: Critical and precious materials requirement in the wind energy system in the EU 27 by 2020. - Highlights: • The critical and precious materials consumption were calculated in wind energy system in the EU 27. • The future requirement of critical and precious materials was estimated in the EU 27 by 2020. • Fluorspar, silver, magnesium, indium, gold and tantalum are the mainly used and required materials. • This research approach could be applied to other industrial sectors as well as other renewable technology. - Abstract: Critical materials as well as rare earth elements and precious metals such as platinum, gold and silver are used significantly for computer hard disk drives, mobile phones, hybrid electric vehicles, batteries, renewable energy system and many other applications. It is therefore important to quantify and estimate both current stocks and flows of such materials, as well as future requirement for industries and economies. In this study, which is focused on wind energy system in the European Union (EU) 27, the current consumption and future requirement of critical and precious materials were calculated and estimated using the wind power production dataset from ecoinvent and data from National Renewable Energy Action Plan (NREAP). It is shown that fluorspar has been the most consumed material to date, and will probably be the most required material in the future. Among other critical and valuable materials, the main materials used for current wind energy system are silver, magnesium, indium, gold and tantalum. These materials will also be required significantly by 2020 for the wind energy system in the EU 27. It is argued that these results should be connected to the future energy and material policy and management

  20. Energy Security of Russia and the EU: Current Legal Problems

    Energy Technology Data Exchange (ETDEWEB)

    Seliverstov, S.

    2009-07-01

    Security of energy supply is a cornerstone of European energy policy. It receives specific mention both in the Constitution Treaty and in the Lisbon Treaty. Of course, energy and energy-generated revenues are vital for Russia as well. It is a common understanding that Russia and the EU are extremely interdependent in terms of energy. On the one hand, Russia is the strategic energy supplier to the EU as a whole; for some member states Russian supplies represent the only source of the external energy flows. On the other hand, the revenues generated from the west-bound supplies of oil and gas constitute a significant share of the overall export income and of the budget of Russian Federation. Taking the interdependency as a point of departure the present article answers the following questions: What are the differences and the similarities in the European and the Russian approaches towards security of energy supply? Is their understanding of energy security so different? What are the current legal instruments guiding interaction in this sphere? What are the actual trends that could give some indication of how the situation may develop in the future? - While the concepts of 'security of energy supplies' or of 'energy security' are theoretical in nature, the ways the concepts are understood and the legal framework for them directly influences the way they are applied in practice.

  17. CERN Radiation Protection (RP) calibration facilities

    CERN Document Server

    AUTHOR|(CDS)2082069; Macián-Juan, Rafael

    Radiation protection calibration facilities are essential to ensure the correct operation of radiation protection instrumentation. Calibrations are performed in specific radiation fields according to the type of instrument to be calibrated: neutrons, photons, X-rays, beta and alpha particles. Some of the instruments are also tested in mixed radiation fields as often encountered close to high-energy particle accelerators. Moreover, calibration facilities are of great importance to evaluate the performance of prototype detectors; testing and measuring the response of a prototype detector to well-known and -characterized radiation fields contributes to improving and optimizing its design and capabilities. The CERN Radiation Protection group is in charge of performing the regular calibrations of all CERN radiation protection devices; these include operational and passive dosimeters, neutron and photon survey-meters, and fixed radiation detectors to monitor the ambient dose equivalent, H*(10), inside CERN accelera...

  18. Fermi comes to CERN

    CERN Multimedia

    2009-01-01

    In only 10 months of scientific activity, the Fermi space observatory has already collected an unprecedented wealth of information on some of the most amazing objects in the sky. In a recent talk at CERN, Luca Latronico, a member of the Fermi collaboration, explained some of their findings and emphasized the strong links between High Energy Physics (HEP) and High Energy Astrophysics (HEA). The Fermi gamma-ray telescope was launched by NASA in June 2008. After about two months of commissioning it started sending significant data back to the Earth. Since then, it has made observations that are changing our view of the sky: from discovering a whole new set of pulsars, the greatest total energy gamma-ray burst ever, to detecting an unexplained abundance of high-energy electrons that could be a signature of dark matter, to producing a uniquely rich and high definition sky map in gamma-rays. The high performance of the instrument comes as ...

  19. Incentives to improve energy efficiency in EU Grids

    Energy Technology Data Exchange (ETDEWEB)

    Papaefthymiou, G.; Beestermoeller, C.; Gardiner, A.

    2013-04-15

    The Energy Efficiency Directive (2012/27/EU) includes provisions related to network tariffs and regulation. It is timely therefore to revisit the potential options for energy efficiency in grids, the treatment of energy efficiency in network tariffs and alternative policies for improving energy efficiency. This project builds on work done previously for the European Copper Institute in this area. In this paper, we concentrate on energy efficiency in electricity network design and operation. Other articles in the Directive relate to the role of the network tariffs and regulations in enabling or incentivising the provision of energy efficiency to end users. In section 2, we describe technical efficiency measures to reduce losses (improve energy efficiency) in the grid. Section 3 reviews grid tariffs in three countries to identify whether they provide incentives or disincentives for energy efficiency in the grid. Section 4 discusses and evaluates alternative regulations for energy efficiency in grids. Section 5 concludes and discusses the main components of the optimal policy framework.

    Calliope, P.; Dalianis, C.

    1996-01-01

    Interest on energy crops varies greatly among EU regions. Certain climatic conditions prevailing in the areas, determine the coice of the energy crop which is going to be used as raw material for energy production. Furthermore, energy markets, farm structure and set aside regulations as well as national policy play a critical role to biomass exploitation for energy purposes. A common methodology was developed (Moore, 1996) for comparing costs of different options for ''biomass-to-energy systems'' across six EU countries (figure 1). This methodology was developed in the framework of an AIR Concerted Action financed by DGXII of EU and entitled ''Development of a Standard Methodology for Integrating Non-Food Crops in Rural Areas with Niche Energy Markets''. Cost estimations were done form the first stage of raw material production till the final energy product (kWh of heat and electricity or lt of liquid biofuel. In this paper, only the raw material production cost estimation phase will be presented. (Author)

    2003-01-01

    The name Horst Wenninger has been closely connected to current and future developments at CERN. On 30 September, he retired from CERN after 35 years. In the 1960s, while working as an assistant at the Institute for High Energy Physics of the University of Heidelberg, Horst Wenninger was already participating in bubble chamber experiments at CERN. From 1968 onwards, when he joint the BEBC project, he worked at CERN as member of the BEBC construction and operations team for almost 20 years, starting off as a young physicist, occupying key roles as BEBC coordinator, becoming the BEBC group leader during the time of its full exploitation, and seeing the termination of the project in 1984. (You can still see the BEBC tank and piston on the lawn in front of Microcosm.) In 1984 the Director General Herwig Schopper appointed him Leader of the Experimental Physics Facilities (EF) Division. This division continued to provide support for large experimental facilities, e.g. the OMEGA spectrometer, and experiments such ...

    Full Text Available The correct functioning of a collimation system is crucial to safely operate highly energetic particle accelerators, such as the Large Hadron Collider (LHC. The requirements to handle high intensity beams can be demanding. In this respect, investigating the consequences of LHC particle beams hitting tertiary collimators (TCTs in the experimental regions is a fundamental issue for machine protection. An experimental test was designed to investigate the robustness and effects of beam accidents on a fully assembled collimator, based on accident scenarios in the LHC. This experiment, carried out at the CERN High-Radiation to Materials (HiRadMat facility, involved 440 GeV proton beam impacts of different intensities on the jaws of a horizontal TCT. This paper presents the experimental setup and the preliminary results obtained, together with some first outcomes from visual inspection and a comparison of such results with numerical simulations.

  6. Protocol to the 1991 Co-operation Agreement between CERN and the Department of Atomic Energy of the Government of India (DAE)

    CERN Document Server

    2005-01-01

    CERN has signed a Cooperation Agreement with the Department of Atomic Energy of India (DAE) in 1991, followed in 1996 by a Protocol for collaboration within the framework of the LHC project. The work by way of Indian in-kind contributions to the LHC was coordinated by the DAE, and was compensated by CERN through payments into the 'LHC India Fund'. These payments were calculated at the level of half of the estimated European value of the in-kind contributions received. The collaboration was highly successful and was extended in 2003. In the previous year India had been granted Observer Status by the CERN Council. As the LHC Project approaches completion, the collaborations under the 1996 Protocol and the 2003 Extension are now coming to an end. With India rapidly developing into one of the world's most active and advanced accelerator centres, it seems fitting that CERN and India should continue their collaborative efforts in other accelerator areas of mutual interest. The Protocol proposed in this document has...

  7. Technical efficiency of economic systems of EU-15 countries based on energy consumption

    International Nuclear Information System (INIS)

    Bampatsou, Christina; Papadopoulos, Savas; Zervas, Efthimios

    2013-01-01

    In the present study, Data Envelopment Analysis is used to determine the Technical Efficiency index of EU-15 countries from 1980 to 2008, using cross-country comparison. Technical Efficiency index represents the capacity of an economy to produce a higher level of Gross Domestic Product for a given level of total energy input. The level of the Technical Efficiency index is determined from the energy mix (fossil fuels, non-fossil fuels, nuclear energy) of each country and depends on the maximization level of the production of the Gross Domestic Product of the economic system, without waste of energy resources. The current study is applied in the case of the EU15 countries. Its scope is to highlight the differentiations of country classifications before and after the integration of nuclear energy in the energy mix of each country. The main result is that the integration of nuclear energy as an additional input in the energy mixture affects negatively the Technical Efficiency of countries. Also, when an economy achieves a decrease of the energy consumption produced from fossil fuels, and a better exploitation of renewable energy sources, clearly improves its capacity to produce more output with the given levels of inputs. - Highlights: ► Technical efficiency index of EU-15 countries is determined through the DEA method. ► Level of the TE index is determined from the energy mix used in each country. ► TE level depends on the maximization level of GDP without waste of energy resources. ► Capacity of an economy to produce more GDP for a given energy input is determined. ► TE differentiation before and after the integration of nuclear energy is performed

  8. A harmonized calculation model for transforming EU bottom-up energy efficiency indicators into empirical estimates of policy impacts

    International Nuclear Information System (INIS)

    Horowitz, Marvin J.; Bertoldi, Paolo

    2015-01-01

    This study is an impact analysis of European Union (EU) energy efficiency policy that employs both top-down energy consumption data and bottom-up energy efficiency statistics or indicators. As such, it may be considered a contribution to the effort called for in the EU's 2006 Energy Services Directive (ESD) to develop a harmonized calculation model. Although this study does not estimate the realized savings from individual policy measures, it does provide estimates of realized energy savings for energy efficiency policy measures in aggregate. Using fixed effects panel models, the annual cumulative savings in 2011 of combined household and manufacturing sector electricity and natural gas usage attributed to EU energy efficiency policies since 2000 is estimated to be 1136 PJ; the savings attributed to energy efficiency policies since 2006 is estimated to be 807 PJ, or the equivalent of 5.6% of 2011 EU energy consumption. As well as its contribution to energy efficiency policy analysis, this study adds to the development of methods that can improve the quality of information provided by standardized energy efficiency and sustainable resource indexes. - Highlights: • Impact analysis of European Union energy efficiency policy. • Harmonization of top-down energy consumption and bottom-up energy efficiency indicators. • Fixed effects models for Member States for household and manufacturing sectors and combined electricity and natural gas usage. • EU energy efficiency policies since 2000 are estimated to have saved 1136 Petajoules. • Energy savings attributed to energy efficiency policies since 2006 are 5.6 percent of 2011 combined electricity and natural gas usage.

    A series of new emission-tunable phosphors Bi{sub 0.95−y}PO{sub 4}:0.05Tb{sup 3+},yEu{sup 3+} were synthesized by a facile hydrothermal method with surfactant-free environment. XRD results indicated that phosphors possess the standard BiPO{sub 4} monoclinic structure. From the luminescence spectra and decay curves, the energy transfer from Tb{sup 3+} to Eu{sup 3+} was confirmed. The efficient Tb{sup 3+} to Eu{sup 3+} energy transfer can be used to tune the emission color from green, yellow to orange by simply changing the concentration of europium, making the materials have potential applications in three-color-based displays and white light illumination. Finally, the energy transfer mechanism between Tb{sup 3+} and Eu{sup 3+} was demonstrated to be the electric quadrupole–quadrupole interaction based on Dexter's energy transfer formula and the Inokuti–Hirayama model. - Highlights: • BiPO{sub 4}: Tb{sup 3+}, Eu{sup 3+} phosphor was synthesized by a facile hydrothermal method. • Energy transfer from Tb{sup 3+} to Eu{sup 3+} in BiPO{sub 4} was firstly studied. • The Q–Q interaction is the main mechanism for energy transfer from Tb{sup 3+} to Eu{sup 3+}. • BiPO{sub 4}: Tb{sup 3+}, Eu{sup 3+} has potential applications in white LEDs and display devices.

    In its continual tour of CERN Member States, the European Committee for Future Accelerators (ECFA) visited Lisbon, Portugal, on 21-22 April, where it met at the Instituto Superiore Tecnico, a technical university with 9,000 students. Portuguese particle physics is in a particularly healthy situation, having developed considerably following Portugal's admission to CERN in 1985. With support from Brussels, scientific infrastructure has developed rapidly, although the science base has yet to attain the levels seen in larger nations. The 45-strong population of experimentalists in Portugal, including 14 PhDs, represents a 2.5-fold increase since Portugal joined CERN ten years ago and is in line with the goal stated at the time. This successful development of experimental particle physics has benefited much from physicists returning from abroad (mainly France and the UK). The direct result of the efforts of a few individuals (notably J.M. Gago), this splendid achievement provides an excellent role model for new and potential CERN Member States. At present, particle physics represents some 3 0% of all Portuguese physics publications. This very special role (and the financial support it implies) provides a visible target, but one which can be defended as it provides a catalyst for other national scientific developments. The national hub is the Laboratory for experimental high energy physics and related R&D projects (LIP), with centres in Lisbon (Head, J.M. Gago) and Coimbra (Head, A. Policarpo). LIP, with close links to two universities in Lisbon and to the University of Coimbra, has developed into a centre of expertise and training in electronics, computing and software engineering. Present LIP funding is some 2 million Swiss francs/year (70% in Lisbon and 3 0% in Coimbra), covering most of the salaries of the nonuniversity people, the remainder being supported by grants from Portuguese and European programmes.

    1995-01-01

    At 19.45 on 31 October, CERN's LEP electron-positron collider, equipped with superconducting radiofrequency accelerating cavities, registered its first events at a record collision energy of 130 GeV. During November, LEP went on to operate in the 130-140 GeV collision energy range. Fabrication and installation of the superconducting radiofrequency accelerating cavities needed to boost the energy of LEP's electron and positron beams have speeded up as confidence and expertise have increased. 16 additional cavities were installed in a brief technical stop during October. For the substantially upgraded machine to supply 65 GeV beams immediately and at luminosities comparable to those routinely attained before shows that the complicated technology needed for the superconducting cavities and mastering the machine itself are well under control - yet another remarkable achievement in CERN's tradition of remarkable achievements. Before the end-1995 run, LEP had been operating around the Z resonance at 91 GeV ever since its commissioning in 1989. LEP precision data on the Z, the electrically neutral carrier of the weak nuclear force, is now complete, and attention shifts toward the next major objective, accumulating data on the W, the Z's electrically charged counterpart. Unlike the Z, produced singly in electron-positron annihilations, the electrically charged Ws have to be produced in pairs. During the coming long shutdown, more superconducting modules will be installed to prepare for recommencement of operations in June, this time at collision energies of 161 GeV, allowing a first step across a longawaited 2W threshold. Later in the year more cavities will be ready to boost collision energies to 176 GeV. However in the meantime the LEP experiments, no longer blinded by the Z resonance, will be keeping a sharp eye open for new physics, and in particular for signs of as yet unseen supersymmetric particles. Theorists have long been convinced that our

    Energy Technology Data Exchange (ETDEWEB)

    2013-02-15

    The report shows where Europe needs to be by 2030 in order to reach a fully renewable energy system by 2050. The key findings are that Europe has significant untapped potential for cutting energy use and maximising indigenous power sources that could deliver cheaper and more secure energy. However, this potential is at risk because of a lack of political ambition. There is a particular need for greater clarity on policy frameworks for renewable energy and energy efficiency after 2020 just one investment cycle away. Based on recent research by ECOFYS for WWF, by 2030, the EU: (a) could be using at least 38% less energy (compared to a business as usual projection; (b) could be generating more than 40% of its energy from renewable sources, and (c), by doing both, could reduce its energy related greenhouse emissions by 50% compared to 1990 levels. Achieving such levels would put the EU on track to delivering a 100% renewably powered energy system by 2050 at the latest. It should be noted that while biomass use has been assessed based on the global model, a more detailed sustainability vision for biomass use in Europe is needed.

    In celebration of the 100th year of International Women’s Day on 8 March, a special colloquium looking at high energy physics from a gender studies perspective was held at CERN.   Addressing a packed conference room, Helene Goetschel, a visiting gender studies researcher from Uppsala University, gave a presentation on a subject unfamiliar to most physicists: sociology. And more specifically, on the findings of gender researchers examining the field of high energy physics. “It was heartening to see so many CERN physicists interested in hearing how sociologists and historians see their community,” said Helene. “Examining our personal issues with gender is difficult, and I applaud anyone who takes an interest in the subject.” Helene Goetschel began her academic career in high-energy physics, but encountered a 'glass ceiling' in her work. In 1990, she decided to change the focus of her studies to the history of science – specifically looking ...

    Many strategies have already been proposed for the decarbonisation of the EU energy system by the year 2050. These typically focus on the expansion of renewable energy in the electricity sector and subsequently, electrifying both the heat and transport sectors as much as possible...... are identified and then, the EU27 energy system is modelled to investigate the impact of district heating. The results indicate that a combination of heat savings, district heating in urban areas, and individual heat pumps in rural areas will enable the EU27 to reach its greenhouse gas emission targets by 2050...

    Both in the early universe, at time about one microsecond, and (perhaps) in the interior of neutron stars the energy density is so high that hadrons (protons, neutrons, pions ...) cannot exist : they melt down into a colour conducting "plasma" of quarks and gluons, the most primordial form of what we call matter. At CERN we create "mini-bangs" of matter by colliding heavy nuclei head-on at 33 TeV energy. it appears that such deconfined matter is indeed recreated in these experiments.

    Jones, C.; Webster, W.

    2006-06-01

    European energy markets are undergoing rapid and fundamental change. In 2005 the European Council and European Parliament adopted the second energy liberalisation package, including the new electricity and Natural Gas Directives and the Electricity Regulation. In addition, the European Commission tabled new Directives on Security of Supply and a draft Natural Gas Regulation. This is affecting markets not only in the European Union, but throughout Europe, the Mediterranean, the Balkans and Russia. These changes have affected not only energy law. Community competition law in the energy sector has been evolving quickly, reacting to the restructuring of the markets, and the new commercial partnerships that result. EU Energy Law is a complete and essential reference work for all those advising on and implementing in practice the enormous changes in today's electricity and gas markets. It is written for both legal specialists and for those working in industry responsible for overseeing the move towards open and competitive markets

  4. A study of economic utility resulting from CERN

    International Nuclear Information System (INIS)

    Schmied, H.

    1975-01-01

    The study attempts to quantify the technical and economic benefit to the manufacturing industries involved in CERN contracts, in relation to the expenditures on CERN by its Member States. Interviews were carried out in some 130 European firms, who supplied data on estimates of increased sales and decreased costs due to CERN contracts. This 'economic utility' totals 1,665 million Swiss francs (up to the year 1978), compared with a sales value to CERN of 394 MSF. Utility/sales ratios range from 0.9 to 7.3 for application fields of cables, magnets, cooling systems, vacuum equipment, electronics, and steels; they are as high as 17.3 for computers and 31.6 for precision mechanics. Some 80 per cent of the total reported utility results from sales to markets outside high-energy and nuclear physics, for example, railways, ship-building, refrigeration, power generation and power distribution. For the 877 MSF spent by CERN in European industry from its over-all budget of 3,500 MSF during 1955 to 1973, the total utility is estimated to be nearly 5,000 MSF. The method and procedure of analysis and quantification are discussed in detail and some specific cases are presented as examples. (author)

    2000-01-01

    Full text: Following our long-time tradition we will present under a common header the activities of the seven new units created in 1997 on the basis of the former Department of High Energy Physics: Department of Particle Theory (Dept. V); Department of Leptonic Interactions (Dept XI); Department of Hadron Structure (Dept XII); Department of High Energy Nuclear Interactions (Dept XIII); The ALICE Experiment Laboratory (NAL); The ATLAS Experiment Laboratory (NAT); High Energy Physics Detector Construction Group (PBD). At the end we will list our common activities: lectures and courses as well as seminars. Our research covers a variety of problems of the experimental and theoretical high energy particle physics: the hadronic and leptonic interactions with nucleons and nuclei (characteristics of particle production, including heavy quark physics), e + e - interactions and tests of the Standard Model (also evaluation of radiative corrections), ultrarelativistic heavy ion interactions and search for the quark-gluon plasma, as well as the spectra, composition and interactions of high energy cosmic ray particles. Research on detectors and accelerator components as well as the development of the apparatus for the high energy physics experiments at future accelerators: LHC (CERN, Geneva), RHIC (Brookhaven), B-Factory (KEK, Tsukuba) and TESLA (DESY, Hamburg) is also carried out. The technology of new materials with unique properties such as carbon-carbon composites is also worked on from the point of view of their application in high energy physics experiments. The Division is located in a separate building on the campus of the University of Mining and Metallurgy. This location, close to the Jagiellonian University, facilitates the collaboration with the latter and with the University of Mining and Metallurgy. The joint weekly seminars carried out for nearly 40 years prove this long term tradition. A substantial part of our activities is teaching and training students from

    Rather than examining aggregate emissions trends, this study delves deep into the dynamics affecting each sector of the EU energy system. It examines the structural changes taking place in power production, transport, buildings and industry, and benchmarks these with the changes required to reach the 2030 and 2050 targets. In so doing it aims to influence both the ambition and direction of future policy decisions, both at Member State and EU level. In order to assess the adequacy of the EU and its Member States policies with the 2030 and 2050 decarbonization objectives, this study goes beyond the aggregate GHG emissions or energy use figures and analyse the underlying drivers of emission changes, following a sectoral approach (power generation, buildings, industry, and transport). Historical trends of emission drivers are compared with the required long-term deep decarbonization pathways, which provide sectoral 'benchmarks' or 'corridors' against which to analyse the rate and direction of historical change for each Member State and the EU in aggregate. This approach allows the identification of the necessary structural changes in the energy system and policy interventions to reach deep decarbonization, and therefore the comparison with the current policy programs at European and Member State level. The EU has made significant progress in the structural decarbonization of its energy system. However, despite of this progress, the EU is currently 'off-track' to achieve its objectives by 2030 and 2050. First, the rate of change is insufficient across a large number of the indicators assessed. Second, too much of the change in aggregate emissions has been driven by cyclical effects rather than structural decarbonization, notably the impact of the financial crisis and subsequent slow recovery. Third, long-term decarbonization options, for example to decarbonize industrial processes and materials, are not being adequately prepared. While some policies under the EU's 2030

    High Energy Physics (HEP) benchmark programs are indispensable tools to select suitable computer for HEP application system. Industry standard benchmark programs can not be used for this kind of particular selection. The CERN and the SSC benchmark suite are famous HEP benchmark programs for this purpose. The CERN suite includes event reconstruction and event generator programs, while the SSC one includes event generators. In this paper, we found that the results from these two suites are not consistent. And, the result from the industry benchmark does not agree with either of these two. Besides, we describe comparison of benchmark results using EGS4 Monte Carlo simulation program with ones from two HEP benchmark suites. Then, we found that the result from EGS4 in not consistent with the two ones. The industry standard of SPECmark values on various computer systems are not consistent with the EGS4 results either. Because of these inconsistencies, we point out the necessity of a standardization of HEP benchmark suites. Also, EGS4 benchmark suite should be developed for users of applications such as medical science, nuclear power plant, nuclear physics and high energy physics. (author)

  15. Performance Limitations in High-Energy Ion Colliders

    CERN Document Server

    Fischer, Wolfram

    2005-01-01

    High-energy ion colliders (hadron colliders operating with species other than protons) are premier research tools for nuclear physics. The collision energy and high luminosity are important design and operations considerations. However, the experiments also expect flexibility with frequent changes in the collision energy, lattice configuration, and ion species, including asymmetric collisions. For the creation, acceleration, and storage of bright intense ion beams, attention must be paid to space charge, charge exchange, and intra-beam scattering effects. The latter leads to luminosity lifetimes of only a few hours for heavy ions. Ultimately cooling at full energy is needed to overcome this effect. Currently, the Relativistic Heavy Ion Collider at BNL is the only operating high-energy ion collider. The Large Hadron Collider, under construction at CERN, will also run with heavy ions.

    This final report summarizes activities of the Florida Tech High Energy Physics group supported by DOE under grant #DE-SC0008024 during the period June 2012 – March 2015. We focused on one of the main HEP research thrusts at the Energy Frontier by participating in the CMS experiment. We were exploiting the tremendous physics opportunities at the Large Hadron Collider (LHC) and prepared for physics at its planned extension, the High-Luminosity LHC. The effort comprised a physics component with analysis of data from the first LHC run and contributions to the CMS Phase-2 upgrades in the muon endcap system (EMU) for the High-Luminosity LHC. The emphasis of our hardware work was the development of large-area Gas Electron Multipliers (GEMs) for the CMS forward muon upgrade. We built a production and testing site for such detectors at Florida Tech to complement future chamber production at CERN. The first full-scale CMS GE1/1 chamber prototype ever built outside of CERN was constructed at Florida Tech in summer 2013. We conducted two beam tests with GEM prototype chambers at CERN in 2012 and at FNAL in 2013 and reported the results at conferences and in publications. Principal Investigator Hohlmann served as chair of the collaboration board of the CMS GEM collaboration and as co-coordinator of the GEM detector working group. He edited and authored sections of the detector chapter of the Technical Design Report (TDR) for the GEM muon upgrade, which was approved by the LHCC and the CERN Research Board in 2015. During the course of the TDR approval process, the GEM project was also established as an official subsystem of the muon system by the CMS muon institution board. On the physics side, graduate student Kalakhety performed a Z' search in the dimuon channel with the 2011 and 2012 CMS datasets that utilized 20.6 fb⁻¹ of p-p collisions at √s = 8 TeV. For the dimuon channel alone, the 95% CL lower limits obtained on the mass of a Z' resonance are 2770 Ge

    At CERN, scientists from all over the world design and build innovative instruments to be implemented in the cutting-edge machines used in high-energy physics. Those instruments go on to become part of the world’s most powerful accelerators, Nobel-prize-winning detectors, unique antimatter machines, the first web servers… These are historical pieces and belong to our common heritage. But, what happens to them once they are no longer in use?   New endeavours consistently require new technical developments, and the list of “old” objects belonging to a laboratory like CERN increases over time. As innovative as they might have been when they were created, they are often bulky, sometimes very delicate, and do not always look like everyday tools when they are dismantled. How best to deal with them? “A database of objects suitable for scientific exhibitions has been available on CDS for many years,” says Gigi Rolandi, Chair of CER...

    This report, written in partnership with I4CE and IFPen, provides the first complete and comprehensive assessment of the EU Commission's proposal and its coherence with the 2030 Framework for Climate and Energy policies, demonstrating that: 1 - Re-calibrating the EU ETS requires considering its interactions with complementary climate and energy policies by 2030. Interactions between different policies may induce additional costs vis-a-vis an optimal transition to a low-carbon economy. 2 - Introducing the Market Stability Reserve is necessary to support the ambition of the EU ETS. Guaranteeing MSR effectiveness calls for a governing framework to be established before 2030. 3 - The free allocation mechanism for Phase IV requires more flexible and targeted allocation to sectors most exposed to carbon leakage risk. 4 - Expanding the EU ETS scope with the inclusion of the road transport sector may not necessarily be the most cost-effective way to achieve the GHG 2030 target. 5 - Considering the large scale of ETS auction revenues by 2030, the use of ETS proceeds by the European Commission and by Member States constitutes an increasingly relevant funding source to support decarbonization efforts in non-ETS sectors and to finance R and D in low carbon technologies

    Na{sub 3}Bi(PO{sub 4}){sub 2}:Eu{sup 3+}/Tb{sup 3+}/Dy{sup 3+}/Sm{sup 3+} phosphors were synthesized via a high-temperature solid-state reaction method. The X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), diffuse reflection, photoluminescence (PL) and fluorescent decay curves were utilized to characterize the obtained phosphors. Under n-UV excitation, Na{sub 3}Bi(PO{sub 4}){sub 2}:Eu{sup 3+}/Tb{sup 3+}/Dy{sup 3+}/Sm{sup 3+} samples show the characteristic f-f emissions and present red, green, yellow and orange emission, respectively. When Tb{sup 3+}, Dy{sup 3+} and Sm{sup 3+} were co-doped into the Na{sub 3}Bi(PO{sub 4}){sub 2}:Eu{sup 3+} phosphors, tunable emission colors can be obtained and can be efficiently adjusted by varying the doping ions and the doping concentration. The energy transfer mechanisms were investigated in detail and demonstrated that there is an efficient energy transfer from Tb{sup 3+}, Dy{sup 3+} and Sm{sup 3+} to Eu{sup 3+} via a dipole-dipole interaction mechanism. Additional, as the temperature increases from RT to 150 °C, the PL intensity of Tb{sup 3+}-Eu{sup 3+}, Dy{sup 3+}-Eu{sup 3+} and Sm{sup 3+}-Eu{sup 3+} co-doped phosphors decreased to 86%, 85% and 88%, respectively, which prove good thermal stability. All the CIE coordinates of as-prepared phosphors are displayed and show abundant colors, making these materials have potential applications for n-UV-excited white-LEDs.

    Gd{sup 3+} and Eu{sup 3+} ions co-doped CaCO{sub 3} nanoparticles have been successfully synthesized via carbonization method. The emission spectra of co-doped CaCO{sub 3} phosphors in the range of VUV–vis spectral were studied. The results reveal that the co-doped CaCO{sub 3} phosphors show intense red emission in the VUV range because of the Gd{sup 3+} ions as sensitizers. The energy transfer process from Gd{sup 3+} to Eu{sup 3+} in CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} phosphors was investigated and discussed in terms of the luminescence spectra and the decay curves, which demonstrated that the energy transfer of Gd{sup 3+}→Eu{sup 3+} is efficient. The mechanism of energy transfer from Gd{sup 3+} to Eu{sup 3+} is a resonant transfer, in which electric dipole–dipole interaction plays a leading role. Furthermore, the effect of doping concentration of Eu{sup 3+} ions on the energy transfer efficiency was also investigated. From the photoluminescence (PL) spectra, it was also found that the incorporation of Na{sup +} ions into CaCO{sub 3}:Gd{sup 3+}/Eu{sup 3+} could lead to a remarkable increase of luminescent intensity due to the charge compensation.

    Slovenia was the first EU acceding country which has managed to successfully reach consensus with the European Commission (EC) on the chapters Energy, which comprises nuclear energy, and Environment, which comprises nuclear safety and radiation protection. This practically meant that the EU adopted the position that these two chapters did not, at that stage, require further negotiation. The EC will continue to monitor the progress in adoption and implementation of the EU legislation throughout the negotiations. The activities in relation to the accession of Slovenia to the EU in the area of nuclear energy and nuclear safety are reflected in the transposition of the legislation and establishing the institutions capable of implementing the EU legislation. The importance of regular reporting to the EC on the status is vital for monitoring the progress. The EC issues progress reports for all candidate countries on annual basis and the action plan has been devised by the EC to put some extra pressure on the candidate countries. The position of the EU in the area of nuclear legislation is reflected in the so called Non-binding EU acquis. The actual position of the EU towards each Candidate Country and to these countries as a whole is contained in the document Report on Nuclear Safety in the Context of the Enlargement. The Act on Nuclear and Radiation Safety had been drafted and is planned to be passed by the Parliament in the first half of 2002. The EC is willing to provide support in implementation of projects to strengthen nuclear safety in Slovenia (assistance to the regulatory authority, review of seismic studies, support with the periodic safety review, review and application of PSA studies). The recent status in the preparation of the position of Slovenia in negotiations in to the EU in the field of nuclear energy, nuclear safety and radiation protection shows that Slovenia has still some tasks to be done, but there are no pending issues which might hinder the

    The present report is prepared as part of the project 'Poland - Electricity and gas market development study and practical guidelines for using EU - funds'. The EU structural and cohesion funds are presently considered the most relevant funds concerning support to energy projects. In general, the Polish administration of the EU structural funds is strongly decentralized. The eligible project types to be supported from the various structural funds are described in a number of sector programmes. The sector programmes are described in vertical view, meaning that it is difficult to assess what kind of energy projects are eligible for support and, if eligible, then under which programme. This report presents a horizontal view of the various programmes in order to give an overview of the possibilities of support to energy related projects. The background for this report is a study of the following sector programmes: 1. Improvement of the competitiveness of enterprises. 2. Human resources development. 3. Restructuring and modernization of food sector and rural development. 4. Fisheries and fish processing. 5. Transport - maritime economy. 6. Integrated regional operational programme. 7. Technical assistance. Based on this review, it can be stated that energy projects in general have a low priority but can be supported under various measures within the programmes. (BA)

  20. Energy efficiency in the transport sector in the EU-27: A dynamic dematerialization analysis

    Energy use in the European Union's (EU) transport sector amounted to 340 Mtoe in 1999 with the following increasing trend up to 379 Mtoe in 2007 and a decrease from 2008 on, down to 365 Mtoe in 2010. This changing pattern posed several fundamental questions and uncertainties regarding the broader picture of energy efficiency and environmental protection. One of them refers to absolute changes in energy use efficiency in the transport sector over time and the ways of measuring efficiency. Traditional scientific approaches conceptualized to measure efficiency of energy use do not address annual dynamics of changes in the energy use in a given sector per capita. Thus, they are not precise enough for political and methodological purposes as they do not reflect the exact amount of energy consumed in the respective countries and societies. This paper shows a possible solution to this problem and a new perspective on measuring energy efficiency by using the product generational dematerialization (PGD) indicator. The PGD indicator allows for measuring energy efficiency as a dynamic change of consumption and population occurring simultaneously. Thus, it provides an extension to the traditional methodology commonly used for measuring efficiency. To visualize a practical application of this approach, the paper provides an example of evaluating energy efficiency in the transport sector in the EU-27 in 2000–2010. The results of the analysis show a clear materialization tendency in the transport sector (the energy consumption change exceeded the population growth) until 2007 and a reverse tendency (dematerialization) between 2008 and 2010. As energy consumption has a direct impact on environmental quality and exhaustion of natural resources, the paper points out the necessity of extending sustainable resource management policies by new methodologies and providing more efficient solutions for energy consumption in the transport sector. - Highlights: • PGD indicator proves a

    The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events; CERN elections and appointments; Collaboration agreement between Italian IN FN and the Sinic Academy of Sciences. In 1979, the CERN Committee of Council invited Armin Hermann of the University of Stuttgart to carry out a feasibility study, financed by the Volkswagen Foundation, on the writing of a history of CERN. On the basis of its findings, and a recdmmendation of the CERN History Advisory Committee, the Committee of Council has now authorized the history study which will be carried out by three European Science historians, led by Professor Hermann based at CERN. A few years ago the National Norwegian CERN Committee proposed that CERN might open its doors also to visitors from technical fields in the Member States. The idea is that visitors spending up to a year working in a CERN group, which is doing some front-line work in a technological field, will benefit personally and will carry further expertise back to the home country. A two-day workshop was held at Cornell in November to introduce the high energy physics community to the design of Q new 50 GeV electron- positron storage ring aimed at neutral intermediate boson physics. A very thorough polarization experiment for the direct determination of the amplitude in proton-proton elastic scattering has been carried out at the SIN cyclotron. A workshop is being held at DESY on 10-11 February to discuss the physics with the 2x5 GeV electronpositron DORIS storage ring and potential DORIS improvements; As an appropriate 'Goodwill to all men' message in this first issue of the New Year we reproduce the guidelines proposed by the International Committee for Future Accelerators for the 'interregional utilization of major regional experimental facilities for high energy particle physics research'

    2009-01-01

    In order to study the matter originating from the universe, a new particle accelerator named the Large Hadron Collider (LHC) has been built at CERN. The radiation environment generated by the hadrons collisions in the high energy physics experiments of the LHC will be complex and locally very intense. For monitoring this complex radiation field, dosimeters have been installed in the LHC experiments. In previous study, RadFET dosimeters and PIN diodes have been characterized for their use in the particle accelerator. However, even if the RadFETs sensors have been already extensively characterized, their radiation response can be affected by their package. Depending on the material and the geometry, the package can induce errors in the dose measurement. In this thesis, a complete study has been carried out in order to evaluate its influence. Concerning the PIN diodes, the readout protocol used for the LHC is no longer valuable for the Super-LHC. Therefore, a complete study on their radiation response has been p...

    Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV-1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(α)( 151 Eu) = 9180+-150 b at 0.0253 eV; sigmasub(α)( 153 Eu) = 375+-20 b at 0.0253 eV; sigmasub(α)(Eu) = 4600+-120 b at 0.0253 eV

    A series of novel color-tunable Ba3Y4O9:Bi(3+),Eu(3+) phosphors were prepared for the first time via the high-temperature solid-state reaction route. The effect of Bi(3+) concentration on the emission intensity of Ba3Y4O9:Bi(3+) was investigated. The emission spectra of the Ba3Y4O9:Bi(3+),Eu(3+) phosphors present both a greenish yellow band of Bi(3+) emission centered at 523 nm, and many characteristic emission lines of Eu(3+), derived from the allowed (3)P1-(1)S0 transition of the Bi(3+) ion and the (5)D0-(7)FJ transition of the Eu(3+) ion, respectively. The energy transfer phenomenon from Bi(3+) to Eu(3+) ions is observed under UV excitation in Bi(3+), Eu(3+) co-doped Ba3Y4O9 phosphors, and their transfer mechanism is demonstrated to be a resonant type via dipole-quadrupole interaction. The critical distance between Bi(3+) and Eu(3+) for the energy transfer effect was calculated via the concentration quenching and spectral overlap methods. Results show that color tuning from greenish yellow to orange red can be realized by adjusting the mole ratio of Bi(3+) and Eu(3+) concentrations based on the principle of energy transfer. Moreover, temperature-dependent PL properties, CIE chromaticity coordinates and quantum yields of Ba3Y4O9:Bi(3+),Eu(3+) phosphors were also supplied. It is illustrated that the as-prepared Ba3Y4O9:Bi(3+),Eu(3+) phosphors can be potential candidates for color-tunable phosphors applied in UV-pumped LEDs.

    2014-01-01

    This paper aims at analysing the factors behind the change in aggregate energy consumption in the EU-27, also identifying differences between member states. The logarithmic-mean Divisia index method (LMDI) is applied to multiplicatively decompose, at the country level, the variation in aggregate energy consumption in the EU-27 member states for the 2001–2008 period. We also analyse the sensitivity of the results when several aggregation levels are considered, with energy intensity used as the criterion to aggregate countries. This allows us to check robustness of results, also enabling an improved understanding of both inter and intra-unit effects. Results indicate that improvements in energy efficiency in the EU-27 were not enough to overcome the pressure of European economic activity on aggregate energy consumption. Mediterranean countries, and especially former communist states, increased their energy consumptions, most of them favoured by structural change. The analysis also reveals that the impact of intra-group movements on aggregate energy consumption is partially offset when moving from higher to lower aggregation levels. - Highlights: • Increase in EU-27 aggregate energy consumption is decomposed through LMDI at 3 levels. • We present the subgroup activity effect and we demonstrate its nulls consequences. • Structural and intensity group effects lose influence when moving to a higher level. • R and D, quality energies, efficient technologies, are main tools to lower energy consumption. • Structural effect: “Green” attitudes and changes in consumer choices, also necessary

    The Compact Linear Collider (CLIC) study at CERN proposes a linear collider with nanometer-size colliding beams at an energy of 3 TeV c.m. ("colliding high energy nanobeams"). The transport, demagnification and collision of these nanobeams imposes magnet vibration tolerances that range from 0.2 nm to a few nanometers. This is well below the floor vibration usually observed. A test stand for magnet stability was set-up at CERN in the immediate neighborhood of roads, operating accelerators, workshops, and regular office space. It was equipped with modern stabilization equipment. The experimental setup and first preliminary results are presented. (10 refs).

    The EU Emission Trading Scheme (EU ETS) for CO 2 -emissions from energy and industry installations reflects a paradigm shift towards market-based instruments for environmental policy in the EU. The centerpieces of the EU ETS are National Allocation Plans (NAPs), which individual Member States (MS) design for each phase. NAPs state the total quantity of allowances available in each period (ET-budget) and determine how MS allocate allowances to individual installations. The NAPs thus govern investments and innovation in energy efficient technologies and the energy sector. In terms of distribution, they predetermine winners and losers. In this paper we analyze and evaluate 25 NAPs submitted to the European Commission (EC) for phase 2 (2008-2012) of the EU ETS. At the macro level, we assess whether the submitted ET-budgets are stringent, and whether they imply a cost-efficient split of the required emission reductions between the EU ETS sectors (energy and industry) and the remaining sectors (transportation, tertiary and households). Comparing the submitted ET-budgets with those already approved by the EC suggests that the EC's decisions significantly improved the effectiveness and economic efficiency of the EU ETS. But given the high share of Kyoto Mechanisms companies are allowed to use, the EU ETS is unlikely to require substantial emission reductions within the EU. At the micro level, we assess (across countries and phases) the allocation methods for existing and new installations, for closures and for clean technologies. A comparison of the NAPs for the second phase and the first phase (2005-2007) provides insights into the (limited) adaptability and flexibility of the scheme. The findings provide guidance for the future design of the EU ETS and applications to other sectors and regions

    1975-01-01

    The study attempts to quantify the technical and economic benefit to the manufacturing industries involved in CERN contracts, in relation to the expenditures on CERN by its Member States. Interviews were carried out in some 130 European firms, who supplied data on estimates of increased sales and decreased costs due to CERN contracts. This 'economic utility' totals 1,665 million Swiss francs (up to the year 1978), compared with a sales value to CERN of 394 MSF. Utility/sales ratios range from 0.9 to 7.3 for application fields of cables, magnets, cooling systems, vacuum equipment, electronics, and steels; they are as high as 17.3 for computers and 31.6 for precision mechanics. Some 80 per cent of the total reported utility results from sales to markets outside high-energy and nuclear physics, for example, railways, ship-building, refrigeration, power generation and power distribution. For the 877 MSF spent by CERN in European industry from its over-all budget of 3,500 MSF during 1955 to 1973, the total utility is estimated to be nearly 5,000 MSF. The method and procedure of analysis and quantification are discussed in detail and some specific cases are presented as examples. (author) [fr

    2012-11-01

    This study examines the lobbying strategies employed by the interest organizations of Germany's energy industries in the process leading up to the EU's Renewable Energy Directive. How did they lobby, and what does this reveal about their perceptions of power relations in the EU? This report focuses on the most controversial part of the Directive: legal prescriptions for support mechanisms to increase the production of renewable energy in Europe. The utilities and the renewables industries disagreed deeply, with the utilities industry favouring an EU-wide green certificate scheme, while the renewables industry pressed for national feed-in tariffs. Nine interest organizations representing these sectors, five German and four at the EU level, serve as cases in this study. Expectations as to lobbying behaviour based on the two theories/theory perspectives of liberal intergovernmentalism (LI) and multi-level governance (MLG) are formulated and tested in a most-likely case design. Result: observations are better described by the MLG perspective than by LI.(auth)

    In case of a resistive transition (quench), fast and reliable extraction of the magnetic energy, stored in the superconducting coils of the electromagnets of a particle collider, represents an important part of its magnet protection system. In general, the quench detectors, the quench heaters and the cold by-pass diodes across each magnet, together with the energy extraction facilities provide the required protection of the quenching superconductors against damage due to local energy dissipation. In CERN's LHC machine the energy stored in each of its eight superconducting dipole chains exceeds 1300 MJ. Following an opening of the extraction switches this energy will be absorbed in large extraction resistors located in the underground collider tunnel or adjacent galleries, during the exponential current decay. Also the sixteen, 13 kA quadrupole chains (QF, QD) and more than one hundred and fifty, 600 A circuits of the corrector magnets will be equipped with extraction systems. The extraction switch-gear is bas...

    This article compares the development of transport and energy use with a focus on carbon dioxide (CO 2 ) emissions in the EU15 countries between 1960 and 2000, and separately by each individual EU country between 1970 and 2000. Based on a review on the literature, immaterialisation can be defined as the reduction of energy intensity and transport intensity; dematerialisation can be defined as the reduction in carbon intensity of energy production and the carbon intensity of transport; decarbonisation can be defined as the reduction in (total and transport) carbon intensity of the whole economy. Although there is a clear pattern of reduction in energy intensity of the economy and carbon intensity of energy production, a similar patter cannot be found in transport. Neither the transport intensity of the economy nor the carbon intensity of transport has been reduced. In particular, freight transport intensity has grown between 1985 and 2000. Data presented by country have shown even more variation. The EU15 countries were aggregated into six groups by cluster analysis to establish the different patterns on each of the three measures. It is concluded that the EU15 countries will have problems in achieving the EU White Paper target of decoupling transport growth from economic growth and the Kyoto target of reducing total CO 2 emissions by 8% from the 1990 level between 2008 and 2012. However, there are some weak signals suggesting a more sustainable passenger transport system. (author)

    "Russia and the EU are the strongest actors on the European continent of the 21st century. Will the strategic partnership between the EU and Russia unite the entire continent under a 'common European home' or will the continent be split in two? Russia joining the rest of Europe is set to proceed initially through the Energy Alliance." (author's abstract)

    EuAl 2 O 4 powder phosphor was prepared by solid-state reaction of EuO and Al 2 O 3 oxides in vacuum. The influence of conditions of preparation on spectral lineshape of Eu 2+ emission was analyzed. It was found that the fluorescence spectra of vacuum-prepared EuAl 2 O 4 samples at 300 K present the superposition of three bands peaked at 430, 500 and 528 nm, corresponding to the 4f 6 5d 1 →4f 7 ( 8 S 7/2 ) transition of Eu 2+ ions in the different sites of EuAl 2 O 4 lattice. The luminescence of Eu 2+ centers in EuAl 2 O 4 host was also studied using the high-pressure spectroscopy up to 67 kbar. It was found that the bright green-yellow fluorescence of EuAl 2 O 4 at 300 K in the band peaked at 520-530nm range can be presented by superposition of two Gaussian sub-bands. The different pressure shifts -23 and -27cm -1 /kbar for two sub-bands were found. Such a structure of the emission spectrum was attributed to the existence of two different Eu 2+ centers in the Eu II 2+ sites of EuAl 2 O 4 lattice with higher coordination number

    The world's highest energy electronpositron collider - CERN's LEP, with a circumference of 27 kilometres - will also be the last such machine to be built as a storage ring. With interest growing in electronpositron physics at energies beyond those attainable at LEP, the next generation of electron-positron colliders must be linear if prohibitive synchrotron radiation power losses are to be avoided. Very high energy linear colliders present many technical challenges but mastery of SLC at Stanford, the world's first electron-positron linear collider, is encouraging. The physics issues of a linear collider have been examined by the international community in ICFA workshops in Saariselka, Finland (September 1991) and most recently in Hawaii (April 1993). The emerging consensus is for a collider with an initial collision energy around 500 GeV, and which can be upgraded to over 1 TeV. A range of very different collider designs are being studied at Laboratories in Europe, the US, Japan and Russia. Following the report of the 1987 CERN Long Range Planning Committee chaired by Carlo Rubbia, studies for a 2 TeV linear collider have progressed at CERN alongside work towards the Laboratory's initial objective - the LHC high energy proton-proton collider in the LEP tunnel.

    On 4 December 2003 a Memorandum of Understanding (MoU) between CERN and the government of New Zealand was signed in the presence of Peter Hamilton, New Zealand's ambassador to Switzerland. This MoU concerns the further development of scientific and technical co-operation in high-energy particle physics between Ernest Rutherford's birthplace and CERN, which now hosts one of the world's most ambitious scientific endeavours, the Large Hadron Collider (LHC).    In anticipation of the MoU, two New Zealand universities (the University of Auckland and the University of Canterbury in Christchurch) have already joined the CMS collaboration to work on pixel detectors, where they can benefit from the expertise of the pixel group at the Paul Scherrer Institute. These detectors are not only valuable in high-energy particle physics, but also serve medical applications.

    The article reports on achievements of various people, staff changes and position opportunities within the CERN organization and contains news updates on upcoming or past events. From 4-6 May 1981 a Topical Conference on the Application of Microprocessors to High Energy Physics will be held at CERN. On 17 October, for the first time at Fermilab, a 'hot' proton beam was cooled by a beam of electrons. In September, two more significant milestones were passed at Fermilab in providing the massive liquid helium temperature refrigeration for the Energy Doubler/Saver. The ZING-P' pulsed neutron facility at Argonne was closed down in August. After the meeting at the Max Planck Institute in Munich on 24 and 25 October, there was no doubt that the high energy physics community fully supports ECFA's recommendation that two big accelerators should be constructed in Europe

    The Eu-doped Cu(In,Eu)Te2 semiconductors with chalcopyrite structures are promising materials for their applications in the absorption layer for thin-film solar cells due to their wider band-gaps and better optical properties than those of CulnTe2.In this paper,the Eu-doped CulnTe2 (Culn1-xEuxTe2,x =0,0.1,0.2,0.3) are studied systemically based on the empirical electron theory (EET).The studies cover crystal structures,bonding regularities,cohesive energies,energy levels,and valence electron structures.The theoretical values fit the experimental results very well.The physical mechanism of a broadened band-gap induced by Eu doping into CuInTe2 is the transitions between different hybridization energy levels induced by electron hopping between s and d orbitals and the transformations from the lattice electrons to valence electrons for Cu and In ions.The research results reveal that the photovoltaic effect induces the increase of lattice electrons of In and causes the electric resistivity to decrease.The Eu doping into CuInTe2 mainly influences the transition between different hybridization energy levels for Cu atoms,which shows that the 3d electron numbers of Cu atoms change before and after Eu doping.In single phase CuIn1-xEuxTe2,the number of valence electrons changes regularly with increasing Eu content,and the calculated band gap Eg also increases,which implies that the optical properties of Eu-doped CuIn1-xEuxTe2 are improved.

  15. Temperature dependent luminescence and energy transfer properties of Na2SrMg(PO4)2:Eu2+, Mn2+ phosphors.

    Eu(2+) singly and Eu(2+)/Mn(2+) co-doped Na2SrMg(PO4)2 (NSMP) phosphors have been prepared via a high-temperature solid-state reaction process. Upon UV excitation of 260-360 nm, the NSMP:xEu(2+) phosphors exhibit a violet band located at 399 nm and a blue band centered at 445 nm, which originate from Eu(2+) ions occupying two different crystallographic sites: Eu(2+)(I) and Eu(2+)(II), respectively. Excitation wavelengths longer than 380 nm can selectively excite Eu(2+)(II) to emit blue light. Energy transfer processes in the Eu(2+)(I)-Eu(2+)(II) and Eu(2+)-Mn(2+) pairs have been observed and investigated by luminescence spectra and decay curves. The emission color of as-prepared samples can be tuned by changing the relative concentrations of Eu(2+) and Mn(2+) ions and adjusting the excitation wavelength. Under UV excitation of 323 nm, the absolute quantum yield of NSMP:0.005Eu(2+) is 91%, which is higher than most of the other Eu(2+)-doped phosphors reported previously. The temperature dependent luminescence properties and decay curves (4.3-450 K) of NSMP:Eu(2+) and NSMP:Eu(2+), Mn(2+) phosphors have been studied in detail. Thermal quenching of Eu(2+) has been observed while the emission band of Mn(2+) shows a blue-shift and an abnormal increase of intensity with increasing temperature. The unusual thermal quenching behavior indicates that the NSMP compound can serve as a good lattice host for Mn(2+) ions which can be used as a red-emitting phosphor. Additionally, the lifetimes for Eu(2+)(I) and Eu(2+)(II) increase with increasing temperatures.

    Full text: The future high energy physics experiments are characterized by an enormous amount of data delivered by the large detectors presently under construction e.g. at the Large Hadron Collider and by a large number of scientists (several thousands) requiring simultaneous access to the resulting experimental data. Since it seems unrealistic to provide the necessary computing and storage resources at one single place, (e.g. CERN), the concept of grid computing i.e. the use of distributed resources, will be chosen. The DataGrid project (under the leadership of CERN) develops, based on the Globus toolkit, the software necessary for computation and analysis of shared large-scale databases in a grid structure. The high energy physics group Innsbruck participates with several resources in the DataGrid test bed. In this presentation our experience as grid users and resource provider is summarized. In cooperation with the local IT-center (ZID) we installed a flexible grid system which uses PCs (at the moment 162) in student's labs during nights, weekends and holidays, which is especially used to compare different systems (local resource managers, other grid software e.g. from the Nordugrid project) and to supply a test bed for the future Austrian Grid (AGrid).

  18. EU Energy Strategy and The Role of Fission Energy

    European Council in its conclusions of 8/9 March 2007 endorsed conditionally as EU objective a 30 percent reduction of GHG emission by 2020 compared to 1990 with a firm commitment to achieve at least 20 percent reduction. Further commitments are reduction of energy consumption by 20 percent compared with projections for 2020 and a 20 percent share of renewable energy sources in overall energy consumption in 2020. Assuming that the reduction of energy consumption by 20 percent relative to projections for 2020, is achieved, as well as increase of renewable in total energy consumption from 4.4 percent share in 1990 to 20 percent in 2020, and provided that nuclear contribution is not reduced, then the CO 2 emission reduction target of 20 percent by 2020 relative to 1990 could be attained. However, both these commitments on consumption decrease and share of renewable in 2007 EC conclusions are in comparison with the 2006 Green Paper so ambitious that reserve measures should be considered. The 2006 Green Paper projected an increase of a share of renewable in total energy production to 12.2 percent by 2030. According to IEA World Energy Outlook 2004 projections, used in Green Paper, wind power would in 2030 contribute with 11 percent in electricity production, on the level of 480 TWh. This projection would require installed wind power of 170 to 180 GW. With new, considerably higher target for renewable by 2020 and limited scope for hydro and solar power increase, wind power would probably have to be increased by at least 50 percent, to about 250-270 GW, to bring renewable share to the 20 percent in overall energy consumption. At present installed wind power in EC amounts to about 50 GW, so to reach a 20 percent target for renewable by 2020 over 200 GW of new wind power would have to be built in not much more than 10 years, unless some spectacular advance with solar energy. Assuming that mass installations start by 2010 the required annual construction would be about 20 GW

    Experiments have been done at the CERN HiRadMat (High Radiation to Materials) facility in which large cylindrical copper targets were irradiated with 440 GeV proton beam generated by the Super Proton Synchrotron (SPS). The primary purpose of these experiments was to confirm the existence of hydrodynamic tunneling of ultra-relativistic protons and their hadronic shower in solid materials, that was predicted by previous numerical simulations. The experimental measurements have shown very good agreement with the simulation results. This provides confidence in our simulations of the interaction of the 7 TeV LHC (Large Hadron Collider) protons and the 50 TeV Future Circular Collider (FCC) protons with solid materials, respectively. This work is important from the machine protection point of view. The numerical simulations have also shown that in the HiRadMat experiments, a significant part of thetarget material is be converted into different phases of High Energy Density (HED) matter, including two-phase solid-liquid mixture, expanded as well as compressed hot liquid phases, two-phase liquid-gas mixture and gaseous state. The HiRadMat facility is therefore a unique ion beam facility worldwide that is currently available for studying the thermophysical properties of HED matter. In the present paper we discuss the numerical simulation results and present a comparison with the experimental measurements.

    As a basis for the design and development of molten salt mixtures, thermodynamic calculations of the phase diagrams and thermodynamic properties were carried out on the EuBr 2 unary and LiBr-EuBr 2 and NaBr-EuBr 2 binary systems over a wide temperature and composition range, respectively. The Gibbs energy of EuBr 2 was evaluated using an independent polynomial to fit the experimental heat capacity, the thermodynamic parameters for each phase in the LiBr-EuBr 2 and NaBr-EuBr 2 systems were optimized by using available experimental information on phase diagrams. A regular substitutional solution model for the liquid phase and Neumann-Kopp rule for the stoichiometric compound LiEu 2 Br 5 were adopted to reproduce the experimental data with reasonable excess Gibbs energy. Comparisons between the calculated phase diagrams and thermodynamic quantities show that all reliable experimental information is satisfactorily accounted for by the present thermodynamic description. Some thermodynamic properties were predicted to check the suitability of the present calculation.

The test has been conducted in a high-energy electron beam facility at the CERN PS in the energy range of 1-10 GeV showing an energy dependence of the TR X-ray photon produced and hence the value γ=E/mc 2 of the charged particle

    Comparative analysis of bulk, non-coated and core-shelled nanocrystalline YVO{sub 4}:Eu was performed by means of time-resolved luminescence and VUV excitation luminescence spectroscopy techniques. Nanocrystalline YVO{sub 4}:Eu samples – both as-prepared and YF{sub 3} core-shelled – have been synthesized by means of a microwave-assisted synthesis in ionic liquids, which allows to obtain 10–12 nm nanoparticles with high crystallinity. The results show noticeable differences between bulk and nanocrystalline YVO{sub 4}:Eu in photoluminescence experimental data, which explains by influence of the nanocrystal surface. A YF{sub 3} core-shell layer around YVO{sub 4}:Eu nanoparticles partially recovers the intensity of the Eu{sup 3+} emission. It is demonstrated that the Eu{sup 3+} luminescence recovery is achieved at the expense of the suppression of the intrinsic emission but not due to the passivation of surface loss centers in core-shelled nanocrystals. It is also shown that surface loss processes are the reason of the degradation of energy transfer efficiency from the host lattice to Eu{sup 3+} under high-energy excitations in vacuum ultraviolet spectral range.

    The main focus of the workshop was on collimators and beam absorbers for (mainly) High Energy Hadron Accelerators, with the energy stored in the beams far above damage limit. The objective was to better understand the technological limits imposed by mechanisms related to beam impact on materials. The idea to organise this workshop came up during the High Intensity High Brightness Hadron Beams, ICFA-HB2006 in Japan [1]. The workshop was organised 3-5 September 2007 at CERN, with about 60 participants, including 20 from outside CERN. About 30 presentations were given [2]. The event was driven by the LHC challenge, with more than 360 MJoule stored in each proton beam. The entire beam or its fraction will interact with LHC collimators and beam absorbers, and with the LHC beam dump blocks. Collimators and beam absorbers are also of the interest for other labs and accelerators: - CERN: for the CNGS target, for SPS beam absorbers (extraction protection) and collimators for protecting the transfer line between SPS an...

    Red luminescence emission in ZrO2:Gd 3+ –Eu 3+ nanocrystal under 250 nm radiation excitation is achieved. These materials exhibit a tetragonal phase that is retained by the presence of lanthanide ions. Thus, a study of the optical properties as a function of the dopant concentration was been carried out without the deleterious effects of having segregation of other crystalline phases. We analyze the emission and lifetime curves as a function of dopant concentration through a rate equation simulation, finding an excellent fitting. As results, the nonradiative and radiative relaxation constants, as well as a quantitative estimation of the energy transfer processes among Eu 3+ , Gd 3+ and O 2− ions are reported for the first time. The proposed model can be extended (or applicable) to explain the fluorescence dynamics in other nanomaterials doped with Eu 3+ and Gd 3+ under UV excitation. -- Highlights: • ZrO 2 nanocrystal exhibits a tetragonal phase in the presence of Eu and Gd dopants. • Emission and lifetimes as a function of dopant concentration were analyzed by rate equation model. • Quantitative estimation of the energy transfer processes among Eu 3+ , Gd 3+ and O 2− ions are reported

    A condensed version is given of CERN report ''Economic utility resulting from CERN contracts'' by the same authors, which attempts to quantify the economic benefit to high technology manufacturing industries involved in CERN contracts, in relation to their sales to CERN. It covers the period 1973 to 1987 and complements an earlier study made in 1973-1975. Interviews were carried out in 166 European firms of which the majority supplied estimates of increased sales and cost savings due to CERN contracts. This ''economic utility'' totals 3107 million Swiss francs (up to the year 1987) compared to sales to CERN in 1973 to 1982 amounting to 748 million Swiss francs in 1982 prices. It is estimated that, by 1987, CERN's high technology purchases made in 1973 to 1982 will have generated economic utility amounting to about 60% of the overall cost of the organization during the same period.

    The construction of the Large Hadron Collider at CERN is in its final phase, and commissioning with beam is scheduled to begin before the end of 2007. It is now time to prepare for increasing as much as possible the performance of this unique instrument to maximize the benefits for physics. An essential part of the proposed luminosity upgrade plan is the replacement of the CERN PS and its injectors by a 50 GeV proton synchrotron (PS2) and a 4 GeV superconducting linac (SPL). The design of the SPL has recently been updated and the optimization of its high-energy part will continue until ~2010. For the foreseen luminosity upgrade of the LHC a low-power version of the SPL (LP-SPL) is under study, which can be upgraded to a multi-megawatt machine providing beam to high-power proton users such as neutrino facilities and/or radio-active beam facilities. The construction start of the low-energy normal conducting SPL front-end, the 160 MeV "Linac4", is scheduled for January 2008, with the goal of being operational as...

Plasmas 21, 080701 (2014)], we reported results on beam-target interaction experiments that have been carried out at the CERN HiRadMat (High Radiation to Materials) facility using extended solid copper cylindrical targets that were irradiated with a 440-GeV proton beam delivered by the Super Proton Synchrotron (SPS). On the one hand, these experiments confirmed the existence of hydrodynamic tunneling of the protons that leads to substantial increase in the range of the protons and the corresponding hadron shower in the target, a phenomenon predicted by our previous theoretical investigations [Tahir et al., Phys. Rev. ST Accel. Beams 25, 051003 (2012)]. On the other hand, these experiments demonstrated that the beam heated part of the target is severely damaged and is converted into different phases of high energy density (HED) matter, as suggested by our previous theoretical studies [Tahir et al., Phys. Rev. E 79, 046410 (2009)]. The latter confirms that the HiRadMat facility can be used to study HED physics. In the present paper, we give details of the numerical simulations carried out to understand the experimental measurements. These include the evolution of the physical parameters, for example, density, temperature, pressure, and the internal energy in the target, during and after the irradiation. This information is important in order to determine the region of the HED phase diagram that can be accessed in such experiments. These simulations have been done using the energy deposition code fluka and a two-dimensional hydrodynamic code, big2, iteratively.

  15. A Low Carbon EU Energy System and Unconventional Sources

    The paper investigates the potential role of unconventional fossil fuels in a global low carbon energy system. Making use of a systemic approach, the paper presents an original application of a global partial equilibrium energy system model (TIAM-JET). In order to give a worldwide perspective with higher detail on European energy systems, the model links a set of extra-European macro-regions to the 30 European countries. First, a review of the most recent estimates of the available stocks of unconventional hydrocarbon resources is used to build the set of assumption for the scenario analysis. Secondly, a set of scenarios assuming different availability and cost of unconventional fuels are added to both a Current Trend scenario and a Carbon Constrained (CC) scenario, to explore the perspectives of unconventional gas and oil in a scenario halving CO 2 emissions by 2050, which is consistent with a 2 degree temperature increase. The results show if/how unconventional sources can contribute to the robustness of the European energy system with respect to the stress of a strong carbon constraint. We define this robustness as the capacity of the energy system to adapt its evolution to long-term constraints and keep delivering energy services to end users. In our approach robustness represents the long-term dimension of energy security. Assessing this ''system property'' requires analysing the wide range of factors that can exercise a stabilizing influence on the energy services delivery system, together with their relations, actual interactions and synergies. The energy system approach used for the analysis seeks to take into account as much of this complexity as possible. We assess the robustness of the EU system to the carbon constraint by looking at how the CC scenario affects energy system costs and energy prices under scenarios with different deployment of unconventional sources. This provides insights on the synergies and/or trade-offs between energy security and

    EuCARD-2 is a project partly supported by FP7 European Commission aiming at exploring accelerator magnet technology for 20-T dipole operating field. The EuCARD-2 collaboration is liaising with similar programs for high-field magnets in the U.S. and Japan. EuCARD-2 focuses, through the work package 10 “future magnets,” on the development of a 10-kA-class superconducting high-current-density cable suitable for accelerator magnets, for a 5-T stand-alone dipole of 40-mm bore and about 1-m length. After stand-alone testing, the magnet will be inserted in a large bore background dipole, 10-18 T. This paper reports on the design and development of models, which are called Feather0, wound with REBCO Roebel cable. Based on aligned block design to take advantage of the anisotropy of the REBCO tapes, Feather0 is a precursor of Feather2, which should reach the project goals in 2016. Feather0 is planned to be tested both in stand alone and as an insert mounted in the CERN Fresca facility providing 10-T background fiel...

    Hyperfine interactions in europium orthophosphate EuPO{sub 4} were investigated using {sup 151}Eu Mössbauer spectroscopy from 6 to 300 K. The value of the quadrupole splitting and the asymmetry parameter were refined and further substantiated by nuclear forward scattering data obtained at room temperature. The temperature dependence of the relative absorption was modeled with an Eu specific Debye temperature of 221(1) K. Eu partial lattice dynamics were probed by means of nuclear inelastic scattering and the mean force constant, the Lamb-Mössbauer factor, the internal energy, the vibrational entropy, the average phonon group velocity were calculated using the extracted density of phonon states. In general, Eu specific vibrations are characterized by rather small phonon energies and contribute strongly to the total entropy of the system. Although there is no classical Debye like behavior at low vibrational energies, the average phonon group velocity can be reasonably approximated using a linear fit.

  20. ChemicalVia: a CERN-patented technology for use in high-density circuits

    2003-01-01

    High-density multilayer printed circuits such as those pictured here are found in miniaturized modern equipment from video cameras to mobile phones. Adjacent layers in these circuits are electrically connected by microvias, consisting of a small-diameter hole (usually 50 µm) with a thin metal-deposited surface covering their cylindrical walls to ensure local conductivity between the two layers. ChemicalVia is a new method, patented by CERN, to make microvias on high-density multilayer printed circuits using chemicals rather than complex laser, plasma or photoimaging technology. The process is compatible with all standard printed-circuit assembly lines, and has the advantages of low initial investment and reduced manufacturing costs. http://www.cern.ch/ttdatabase

    A multi-functional ligand, 5-acryloxyethoxymethyl-8-hydroxyquinoline (Hamq), was synthesized, which contained a polymerizable C=C double bond for the copolymerization with other vinyl monomers and acted as photon antenna able to transfer energy to Eu{sup 3+} ions effectively. The triplet state energy of Hamq was determined to be 22,370 cm{sup -1} via the phosphorescence spectra of Hamq and its gadolinium complex. The title complex monomer Eu(tta){sub 2}(amq) was prepared by coordination reaction of Hamq with europium isopropoxide and 2-thenoyltrifluoroacetone (Htta) in dry organic solvents under argon atmosphere and characterized by elemental analysis and IR spectrum. The photophysical properties of the complex were studied in detail with UV-vis, luminescence spectra, luminescence lifetime and quantum yield. The complex exhibited nearly monochromatic red emission at 612 nm, a remarkable luminescence quantum yield at room temperature (30.6%) upon ligand excitation and a long {sup 5}D{sub 0} lifetime (389 {mu}s), which indicated that the ligand Hamq could sensitize the luminescence of Eu(III) ion efficiently in Eu(tta){sub 2}(amq), resulting in a strong luminescence of its copolymer poly[MMA-co-Eu(TTA){sub 2}(amq)] under UV excitation. The excellent luminescence properties of the complex made it not only a promising light-conversion molecular device but also an excellent luminescent monomer. - Highlights: >iWe designed and synthesized a highly luminescent Eu-complex monomer. > Quantum yield and lifetime of the complex are 30.6% and 389 {mu}s, respectively. > Excellent luminescence of the complex made it an excellent luminescent monomer.

    The paper investigates and reports policies for and the developmental trend of petroleum substitution energy in the E.U. The technology of 18 wind turbine makers in West Europe is on a level that they can almost sell MW-class turbines for practical use. The wind turbine industry in Denmark is on a level of No.1 of the world, and occupies approximately 50% of the world market share. The capacity of the wind power generation in Germany which finished the installation at the end of 1995 exceeded 1000 MW. EEWC has recently been established as an organization for using waste as energy. Municipal solid wastes discharged in West Europe are regarded to be equivalent to 5% of all the power demand there. In Spain, biomass is a petroleum substitution energy source which is most used. A target amount for the use set by the government is equal to 427000 tons in oil. Biomass is most used in the residential field, and it is mainly the use of agricultural and forestry wastes as fuel. Rapeseed oil is studied as fuel for bio car. In Denmark, production of rapeseed as fuel use crop is increasing. 14 refs.

  7. Decarbonising the energy intensive basic materials industry through electrification – Implications for future EU electricity demand

    2016-01-01

    The need for deep decarbonisation in the energy intensive basic materials industry is increasingly recognised. In light of the vast future potential for renewable electricity the implications of electrifying the production of basic materials in the European Union is explored in a what-if thought-experiment. Production of steel, cement, glass, lime, petrochemicals, chlorine and ammonia required 125 TW-hours of electricity and 851 TW-hours of fossil fuels for energetic purposes and 671 TW-hours of fossil fuels as feedstock in 2010. The resulting carbon dioxide emissions were equivalent to 9% of total greenhouse gas emissions in EU28. A complete shift of the energy demand as well as the resource base of feedstocks to electricity would result in an electricity demand of 1713 TW-hours about 1200 TW-hours of which would be for producing hydrogen and hydrocarbons for feedstock and energy purposes. With increased material efficiency and some share of bio-based materials and biofuels the electricity demand can be much lower. Our analysis suggest that electrification of basic materials production is technically possible but could have major implications on how the industry and the electric systems interact. It also entails substantial changes in relative prices for electricity and hydrocarbon fuels. - Highlights: • Energy intensive basic materials industry has a high share in EU greenhouse gas emissions. • Decarbonising these industries is very important, but still relatively unexplored. • Electrification is possible regarding renewable energy resources and technologies. • Combination with energy and materials efficiency, biofuels and CCS is crucial. • Electrification needs very high amounts of electricity and strong policies.

    The ISR results on the differential cross-sections for pp and anti-pp show unambiguously that the crossing-odd amplitude is still important at very high energies. Comparison of ISR and CERN collider anti-pp data suggests that the crossing-odd amplitude is growing maximally fast with energy. We explore the phenomenological consequences of such a ''maximal odderon'' behaviour at TeV energies

    Optimum distribution of energy supply systems can result in large savings in industrial facilities and production devices. Identifying the configuration of existing equipment and its loading, in order to minimize total energy consumption and at the same time satisfy given load demands, has very high payback potential. This paper presents the principle of trigeneration, the technology that can offer a highly efficient way of converting primary fuel (gas, oil) into useful energy as electricity, heat and chilled water simultaneously. It explains different factors that must be considered for such systems to be economically feasible. Some examples of industrial trigeneration systems are analysed and discussed to illustrate the application. Also the possibility of implementation of trigeneration at CERN is discussed, taking into account the existing cogeneration system, power supply structure, secondary energy demands, as well as future developments in our energy policy.

    Graphical abstract: - Highlights: • Silver nanoparticles are precipitated from the borate glasses during the melting process without any further heat treatment. • The reduction of Eu 3+ ions to Eu 2+ ions is presented in this material. • The intensity of Ag + luminescence. • The introduction of Eu ions accelerated the reaction between Eu 2+ ions and silver ions inducing the silver clusters formation. - Abstract: Ag + doped sodium borate glasses with different Eu ions concentration were prepared by the melt-quenching method. The absorption at about 410 nm which was caused by the surface plasmon resonance (SPR) of Ag nanoparticles (NPs) is promoted with increasing of Eu ions concentration. Meanwhile, the luminescent spectra showed that the emission intensity of Ag + decreased while that of the Ag aggregates increased simultaneously. The results indicated that the Ag ions intend to form the high-polymeric state such as Ag aggregates and nanoparticles with increasing of europium ions. Owing to the self-reduction of Eu 3+ to Eu 2+ in our glass system, it revealed that Ag + has been reduced by the neighboring Eu 2+ which leads to the formation of Ag aggregates and the precipitation of Ag NPs in the matrix. In addition, energy transfer (ET) process from Ag + /Ag aggregates to the Eu 3+ was investigated for the enhancement of Eu 3+ luminescence

    Understanding of chemical behavior of actinide in a groundwater flow is important for assessing the possibility of their migration with water flows in a radioactive waste disposal site. Uranium is ubiquitous in the environment and a major actinide in a nuclear fuel cycle. Americium and curium having isotopes of long half life are minor actinides in a spent fuel. If a minor actinide coexists with uranium in a groundwater flow, some interactions between them could be expected such as minor actinide adsorption onto uranium precipitates and competition with each other for an adsorption to a mineral surface site. Eu(III) ion is frequently used as a chemical analogue of Am(III) and Cm(III) ions in a migration chemistry. The luminescent spectra of U(VI) and Eu(III) ions show a dependency on the coordination symmetry around them, and the changes in intensity or bandwidth of spectra can yield valuable information on their local environment. The luminescent lifetime also strongly depends on the coordination environment, and its measurement is valuable in probe studies on micro-heterogeneous systems. The excited U(VI) ion can be quenched through Stern.Volmer process, hydrolysis of excited species, exciplex formation, electron transfer or energy transfer. In case of U(VI)-Eu(III) system, the interaction between two ions can be studied by measuring the effect of Eu(III) ion on the quenching of U(VI) ion luminescence. There are only a few investigations on the interaction between an excited U(VI) ion and a lanthanide(III) ion. In perchlorate solution, the energy transfer to Eu(III) ion occurred only in solutions of pH>3.87. In this study, the quenching of U(VI) luminescence by Eu(III) on a silica surface was measured. The results will be discussed on the basis of a chemical interaction between them

  20. EU initiative on energy infrastructures and continuity of supply

    2004-01-01

    On December 10, 2003, the European Commission presented a comprehensive legislative package about energy infrastructure and continuity of supply. The proposals result in an agglomeration and extension of Community law provisions in the energy sector. A key role is played by the proposed directive ensuring the continuity of electricity supply and investments into infrastructure. This implies the need for the member countries henceforth to define the roles and responsibilities of grid operators and suppliers. The Energy Services Directive is to create a harmonized framework in the field of energy services and energy efficiency by providing common definitions, instruments, and methods. The legislative package has been forwarded to the European Parliament and to the Council. A first reading in the European Parliament is to be completed still in this legislative term by early May 2004. The Energy Ministers of the EU member countries were presented the package on continuity of supply on December 15, 2003. European legislation in the energy sector is keeping member countries busy, leaving them fewer and fewer possibilities for shaping policies of their own. There is danger of overregulation. (orig.)

    Optical and spectroscopic properties of 2.0% Eu(PO 3 ) 3 singly doped and 5.0% Tb(PO 3 ) 3 –2.0% Eu(PO 3 ) 3 codoped zinc–sodium–aluminosilicate glasses were investigated. Reddish-orange light emission, with x=0.64 and y=0.36 CIE1931 chromaticity coordinates, is obtained in the europium singly doped glass excited at 393 nm. Such chromaticity coordinates are close to those (0.67,0.33) standard of the National Television System Committee for the red phosphor. When the sodium–zinc–aluminosilicate glass is co-doped with Tb 3+ and Eu 3+ , reddish-orange light emission, with (0.61,0.37) CIE1931 chromaticity coordinates, is obtained upon Tb 3+ excitation at 344 nm. This reddish-orange luminescence is generated mainly by 5 D 0 → 7 F 1 and 5 D 0 → 7 F 2 emissions of Eu 3+ , europium being sensitized by terbium through a non-radiative energy transfer. From an analysis of the Tb 3+ emission decay curves it is inferred that the Tb 3+ →Eu 3+ energy transfer might take place between Tb 3+ and Eu 3+ clusters through a short-range interaction mechanism, so that an electric dipole–quadrupole interaction appears to be the most probable transfer mechanism. The efficiency of this energy transfer is about 62% upon excitation at 344 nm. In the singly doped and codoped glasses multimode optical waveguides were successfully produced by Ag + –Na + ion exchange, and they could be characterized at various wavelengths. -- Highlights: • Reddish-orange light emission can be generated from Tb 3+ and Eu 3+ codoped zinc–sodium–aluminosilicate glasses excited at 344 nm. • The Eu 3+ is sensitized by Tb 3+ through a non-radiative energy transfer. • Highly multimode waveguides can be fabricated by diluted silver–sodium exchange. • This type of AlGaN LEDs pumped glass phosphors might be useful for generation of reddish-orange light

    In order to investigate the excitation processes in Eu,O-codoped GaN (GaN:Eu,O), the time-resolved photoluminescence signal including the rising part is analyzed. A rate equation is developed based upon a model for the excitation processes in GaN:Eu to fit the experimental data. The non-radiative recombination rate of the trap state in the GaN host, the energy transfer rate between the Eu3+ ions and the GaN host, the radiative transition probability of Eu3+ ion, as well as the ratio of the number of luminescent sites (OMVPE 4α and OMVPE 4β), are simultaneously determined. It is revealed and quantified that radiative transition probability of the Eu ion is the bottleneck for the enhancement of light output from GaN:Eu. We also evaluate the effect of the growth conditions on the luminescent efficiency of GaN:Eu quantitatively, and find the correlation between emission intensity of GaN:Eu and the fitting parameters introduced in our model.

    This paper aims to improve mutual understanding between the EU and US with regard to climate change and energy policy, suggesting specific opportunities for transatlantic cooperation in this area. A background on the environmental, legislative, and economic contexts of the EU and US as they relate to climate policy sets the context. This is followed by an overview of how cap and trade, renewable energy, and sustainable transportation policies have taken shape in the EU and the US. Some observations and lessons learnt within each of these areas are highlighted. Building on these insights, recommendations are made regarding the carbon market, possibilities for new technologies to bridge the valley of death, and best practices and standards.

    Total neutron cross-section measurements have been carried out for natural Eu and its stable isotopes in the energy range from 3 meV to 1 eV. The measurements were performed using two time-of-flight spectrometers installed in front of two of the horizontal channels of the ET-RR-1 reactor. The following results have been obtained: sigmasub(a) ( 151 Eu) = (9180 +- 150) b at 0.0253 eV, sigmasub(s) ( 153 Eu) = (375 +- 20) b at 0.0253 eV, sigmasub(d) (Eu) = (4600 +- 120) b at 0.0253 eV. The contribution of the resonance to the total neutron cross-sections, in the thermal region, was calculated using the single-level Breit-Wigner formula. (orig.)

    Transport activities are essential for economic and social development. Nevertheless, the transport sector has also shown the fastest growth in energy consumption in the European Union and its contribution to increasing greenhouse gas emissions merits the thorough attention of academics and policy makers. In this paper we analyze the relationship of economic growth and transport activities with transport final energy consumption. Energy Kuznets curves are estimated for a panel data set covering the EU27 countries in the period 1995–2009 for total transport energy use, household transport energy use, and productive transport energy use (all three in absolute and per capita energy use terms). The productive transport energy use and gross value added relationship are further considered as per hour worked. Finally, the control variables of energy prices and differences in the economic structures are tested. Empirical results show that the elasticity of transport energy use with respect to gross value added in per capita terms decreases from a threshold for the three transport energy consumption variables, but the turning point of improved environmental quality is not reached in any instance. - Highlights: • Transport EKCs are estimated for the EU countries in the 1995–2009 period. • Total, household and production activity transport energy uses are analyzed. • Data support a concave shape, but the turning point is not reached. • Richer countries have more limited potential for energy efficiency policies. • EKCs elasticity values are considered to support policy interpretations.

    BaSO4:Eu nanophosphor is delicately optimized by varying the concentration of the impurity element and compared to the commercially available thermoluminescent dosimeter (TLD) LiF:Mg,Ti (TLD-100) and by extension also to CaSO4:Dy (TLD-900) so as to achieve its maximum thermoluminescence (TL) sensitivity. Further, the energy dependence property of this barite nanophosphor is also explored at length by exposing the phosphor with 1.25 MeV of Co-60, 0.662 MeV of Cs-137, 85 MeV and 65 MeV of Carbon ion beams. Various batches of the phosphor at hand (with impurity concentrations being 0.05, 0.10, 0.20, 0.50 and 1.00 mol%) are prepared by the chemical co-precipitation method out of which BaSO4:Eu with 0.20 mol% Eu exhibits the maximum TL sensitivity. Further, the optimized nanophosphor exhibits a whopping 28.52 times higher TL sensitivity than the commercially available TLD-100 and 1.426 times higher sensitivity than TLD-900, a noteworthy linear response curve for an exceptionally wide range of doses i.e. 10 Gy to 2 kGy and a simple glow curve structure. Furthermore, when the newly optimized nanophosphor is exposed with two different energies of gamma radiations, namely 1.25 MeV of Co-60 (dose range- 10-300 Gy) and 0.662 MeV of Cs-137 (dose range- 1-300 Gy), it is observed that the shape and structure of the glow curves remain remarkably similar for different energies of radiation while the TL response curve shows little to no variation. When exposed to different energies of carbon ion beam BaSO4:Eu displays energy independence at lower doses i.e. from 6.059 to 14.497 kGy. Finally, even though energy independence is lost at higher doses, the material shows high sensitivity to higher energy (85 MeV) of carbon beam compared to the lower energy (65 MeV of C6+) and saturation is apparent only after 121.199 kGy. Therefore the present nanophosphor displays potential as an energy independent TLD.

  7. Estimating broad-brush rebound effects for household energy consumption in the EU 28 countries and Norway: some policy implications of Odyssee data

    Currently there is a strong policy commitment in European Union (EU) and Organisation for Economic Co-operation and Development (OECD) countries to increase the energy efficiency of residential buildings, and it is widely assumed that this will naturally and automatically reduce domestic energy consumption. However, other factors such as fuel prices, wages, attitudes and lifestyles also influence energy consumption. This paper calculates broad-brush rebound effects based on changes in energy efficiency and energy consumption in each of the 28 EU countries plus Norway, for the years 2000–2011. In doing so, it tests how well the assumption of energy efficiency leading to energy reduction stands up to scrutiny in these lands. It uses the EU’s Odyssee database for efficiency and consumption figures and a commonly employed econometric definition of the rebound effect as an energy-efficiency elasticity. Most older EU lands show rebound effects in the expected range of 0–50%. However, the range for newer EU countries is 100–550%, suggesting that energy efficiency increases are not a good predictor of energy consumption. A more in-depth look at one country, Germany, suggests these results underestimate the rebound effect significantly. This also identifies research needs for specific energy consumption determinants in each country, to find more precisely what is driving consumption levels. - Highlights: • Policymakers frequently link energy efficiency gains with energy consumption falls. • Household energy rebound effects are calculated for EU lands using Odyssee data. • Most older EU lands show results in the range of 0–50% but newer lands show 100–552%. • Energy efficiency gains are not always a reliable predictor of energy consumption. • Targeted research could explore why consumption is often so unrelated to efficiency

    These proceedings contain written versions of lectures delivered at the 1986 CERN School of Computing. Two lecture series treated trends in computer architecture and architectural requirements for high-energy physics. Three other courses concentrated on object-oriented programming, on objects in Ada, and on modularization and re-usability. Expert systems, their applications, and knowledge engineering for graphics were treated by three lectures. The programme of the School covered, in addition, practical aspects of networks, buses for high-energy physics, the design of data-acquisition systems, and examples of on-line systems for particle physics experiments. Optical storage methods, software for distributed systems, symbolic formula manipulation, and solid modelling and rendering were also covered. Experience with transputers was the subject of an unscheduled presentation. (orig.)

    The recent epoch-making scientific discoveries at CERN of the intermediate vector bosons marked the culmination of what could perhaps be described as the most challenging and exciting adventure in the field of accelerator physics. The success of this daring enterprise required the utmost in the physics and engineering of accelerators and levels of reliability reminiscent of the Apollo space program. In what follows, I hope to be able to at least whet your appetites for what may well prove to be the beginning of a new era in High Energy Particle Accelerators

  10. The Gamma Factory proposal for CERN

    2015-01-01

    This year, 2015, marks the centenary of the publication of Einsteins Theory of General Relativity and it has been named the International Year of Light and light-based technologies by the UN General Assembly. It is thus timely to discuss the possibility of broadening the present CERN research program by including a new component based on a novel concept of the light source which could pave a way towards a multipurpose Gamma Factory. The proposed light source could be realized at CERN by using the infrastructure of the existing accelerators. It could push the intensity limits of the presently operating light-sources by at least 7 orders of magnitude, reaching the flux of the order of 10^17 photons/s, in the particularly interesting gamma-ray energy domain of 1 < Ephoton < 400 MeV. This domain is out of reach for the FEL-based light sources. The energy-tuned, quasi-monochromatic gamma beams, together with the gamma-beam-driven, high intensity secondary beams of polarized positrons, polarized muons, neutro...

  11. CERN Enters the Second Year AD

    2001-01-01

    2001 is the year that physics at CERN's new Antiproton Decelerator (AD) really gets up to speed. Changes to the AD since 2000 mean that this year the three experiments, ASACUSA, ATHENA, and ATRAP have had more intense antiproton beams to work with since physics started on 7 May. CERN's Antiproton Decelerator - major improvements for 2001. The AD is a unique machine. Its job is to decelerate not accelerate particle beams, and it has to handle beam energies that vary by an unprecedented factor of 35 from injection to ejection. Since the machine was designed to operate at fixed energy in its first incarnation as a collector of antiprotons for CERN's 1980s proton antiproton collider, this factor of 35 presented a big challenge to the AD team. The team's design goal was to hang onto a quarter of the injected antiprotons through their vertiginous fall in energy, and to repeat the deceleration cycle once per minute. Improvements to the machine over the winter shutdown and through the first four weeks of 2001 run...

    This paper describes the design, calibration and applications at high-energy accelerators of an extended-range Bonner Sphere neutron Spectrometer (BSS). The BSS was designed by the FLUKA Monte Carlo code, investigating several combinations of materials and diameters of the moderators for the high-energy channels. The system was calibrated at PTB in Braunschweig, Germany, using monoenergetic neutron beams in the energy range 144 keV-19 MeV. It was subsequently tested with Am-Be source neutrons and in the simulated workplace neutron field at CERF (the CERN-EU high-energy reference field facility). Since 2002, it has been employed for neutron spectral measurements around CERN accelerators.

    The study evaluates the impacts of EU climate policy on the emission allowance price, electricity prices, the competitiveness of industry and macroeconomic developments in the third EU emission trading period 2013-2020. The economic impacts of climate policy on Finland are compared to the impacts on the entire EU area. It turns out that due to its cold climate and heating energy demand, higher export intensity of the economy and higher energy intensity of the industry Finland pays a higher price for EU climate policy in terms of output and employment losses than the EU on average. The study examines the macroeconomic effects of climate policy also in the more distant future, assuming that climate policy is tightened further in the 2020s. Climate policy implemented by emission trading means that the long-term economic growth in the EU area depends essentially on emission-free electricity production, and no longer on other growth factors, such as the labour supply and productivity growth.
