    There is an ever increasing demand for gamma-ray detectors which can achieve good energy resolution, high detection efficiency, and room-temperature operation. We are working to address each of these requirements through the development of large volume SrI{sub 2}(Eu) scintillator detectors. In this work, we have evaluated a variety of SrI{sub 2} crystals with volumes >10 cm{sup 3}. The goal of this research was to examine the causes of energy resolution degradation for larger detectors and to determine what can be done to mitigate these effects. Testing both packaged and unpackaged detectors, we have consistently achieved better resolution with the packaged detectors. Using a collimated gamma-ray source, it was determined that better energy resolution for the packaged detectors is correlated with better light collection uniformity. A number of packaged detectors were fabricated and tested and the best spectroscopic performance was achieved for a 3% Eu doped crystal with an energy resolution of 2.93% FWHM at 662keV. Simulations of SrI{sub 2}(Eu) crystals were also performed to better understand the light transport physics in scintillators and are reported. This study has important implications for the development of SrI{sub 2}(Eu) detectors for national security purposes.

    Y2O2S:Eu laboratory prepared screens were evaluated as mammographic image receptors and were compared to similarly prepared screens of Gd2O2S:Tb and Y2O2S:Tb phosphor materials, often used in X-ray imaging detectors. The evaluation was performed by determining the Modulation Transfer Function (MTF) and the spatial frequency dependent Detective Quantum Efficiency (DQE). Y2O2S:Eu exhibited higher DQE values at low frequencies and given its good spectral matching with digital optical detectors, it may be appropriate for use in X-ray digital mammography

    In this work, the property of the n-{gamma} discrimination and the response functions of the developed phoswich detector were measured with gamma rays from radioactive sources and neutrons from a Be+Cu target bombarded by protons from the RIKEN ring cyclotron at the Institute of Physical and Chemical Research. The measured response functions were compared with Monte Carlo calculations. We also tested to measure a small amount of neutrons under the intense charged-particles mixed field which was realized in the RIKEN ring cyclotron for the space application. (J.P.N.)

    Granulated BGO, GSO:Ce, YAG:Ce, and CaF sub 2 :Eu; CaF sub 2 :Eu coated with a fluorescent polymer, and combinations of coated and uncoated CaF sub 2 :Eu with ZnS:Ag were evaluated for their ability to discriminate between alpha and beta particles in a flow-cell radiation detector. The evaluations were based on the analysis of pulse shape spectra. Various granulated scintillators were packed into flow cell detectors that were coils of 3.0 mm ODx1.5 mm ID fluorinated ethylene propylene Teflon[reg] tubing positioned between dual photomultiplier tubes for analysis. The best pulse shape discrimination was obtained for a combination of equal masses of uncoated CaF sub 2 :Eu (63-90 mu m) and ZnS:Ag (10 mu m), which had a 9% spillover. Additional research is needed to reduce the spillover.

    Polymer-based scintillator composites have been produced by combining polystyrene (PS) and Gd{sub 2}O{sub 3}:Eu{sup 3+} scintillator nanoparticles. Polystyrene has been used since it is a flexible and stable binder matrix, resistant to thermal and light deterioration and with suitable optical properties. Gd{sub 2}O{sub 3}:Eu{sup 3+} has been selected as scintillator material due to its wide band gap, high density and visible light yield. The optical, thermal and electrical characteristics of the composites were studied as a function of filler content, together with their performance as scintillator material. Additionally 1 wt.% of 2,5-diphenyloxazole (PPO) and 0.01 wt.% of 1,4 di[2-(5phenyloxazolyl)]benzene (POPOP) were introduced in the polymer matrix in order to strongly improve light yield, i.e., the measured intensity of the output visible radiation, under X-ray irradiation. Increasing scintillator filler concentration (from 0.25 to 7.5 wt.%) increases scintillator light yield and decreases the optical transparency of the composite. The addition of PPO and POPOP strongly increased the overall transduction performance of the composite due to specific absorption and re-emission processes. It is thus shown that Gd{sub 2}O{sub 3}:Eu{sup 3+}/PPO/POPOP/PS composites with 0.25 wt.% of scintillator content with fluorescence molecules are suitable for the development of innovative large-area X-ray radiation detectors with huge demand from the industries.

  10. Experimental determination of sensitivity of DN-A-1 dosimeter and 6LiJ(Eu) scintillation detector in sphere polyethylene moderators in the 30 keV neutron energy range

    International Nuclear Information System (INIS)

    DH-A-1 dosimeter and 6LiJ(Eu) detector, located in the center of polyethylene spheres with various diameters, were calibrated by means of neutrons with the energy of about 30 keV. The data on the detectors responses enable one to determine the shape of responses as a function of neutron energy more definitely at the energy range from some keV to some tens of keV. For DN-A-1 dosimeter response at neutrons and at neutrons in the energy range of about 30 keV the agreement is better than the uncertainties of measurements (about 20%)

    A water-stable Eu-coordination polymer (CP), namely [HMIm]Eu(DHBDC)2 (1) (HMIm = 1-hexyl-3-methylimidazolium; H2DHBDC = 2,5-dihydroxytelephthalic acid), was obtained using ionothermal synthesis. 1 represents the first coordination polymer capable of qualitative and quantitative detection of Ba(2+) in aqueous solutions with a fluorescent enhancement that is visible to the human eye, which can be ascribed to the formation of fluorescent compound Ba(DHBDC) (2) during the detection process. Temperature-dependent photoluminescence (PL) makes 1 a potential material for a fluorescence thermometer. Furthermore, the detection process for Ba(2+) using 1 turns the one-PL transition fluorescence thermometer into a two-PL transition fluorescence thermometer, increasing the accuracy of the fluorescence thermometer.

    In recent work, Na co-doping have found to improve the light output of Eu doped LiCaAlF{sub 6} (Eu:LiCAF) for thermal neutron scintillator. We grew Eu 2% and alkali metal 1% co-doped LiSAF crystals by Micro-Pulling down method to understand the effect of alkali metal co-doping on scintillation properties and mechanism compared with LiCAF. In photo- and {alpha}-ray induced radio-luminescence spectra of the all grown crystals, the emissions from d-f transition of Eu{sup 2+} were observed. Without relation to excitation source, decay times of co-doped LiSAF were longer than Eu only doped one. The light yield of Na, K and Cs co-doped LiSAF under {sup 252}Cf neutron excitation were improved. Especially, K co-doped Eu:LiSAF reached 33200 ph/n, which outperformed Eu only doped one by approximately 20% (copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    The European Security and Defence Policy (ESDP) comprises an important part of the EU's Common Foreign and Security Policy (CFSP). The aim of ESDP is to strengthen the EU's external ability to act through the development of civilian and military capabilities for international conflict prevention and crisis management. In December 2003, the EU adopted its first European Security Strategy (ESS). Ever since then, the implementation of the ESS has been regarded as one of the biggest challenges for the EU in CFSP/ESDP matters. Although much progress has been made in its independent security and defence-building process, EU still faces serious problems and difficulties in this policy area. This paper tries to examine these recent developments, assess their impacts in regional-global security, and analyze existing problems and future trends. Finally, the author also examines EU-China engagements in recent years and explores possibilities for their future cooperation in the area of international security.

    The decay of 146Gd to levels of 146Eu has been studied using high resolution x-ray and γ-ray detectors. γ-γ directional correlation studies, using x and γ-ray Ge(Li) detectors, were made to assign the spins of the low lying states in 146Eu. γ-γ coincidence experiments with two Ge(Li) detectors and between Eu x rays and γ rays were performed to pin down the levels of 146Eu. On the basis of these measurements, Jsup(pi) of 4-, 3-, 2-, and 1- have been assigned respectively to the ground, 115.66, 230.51, and 385.11 keV states in 146Eu. More accurate evaluation of the E2 admixtures in the M1 transitions, 114.85, 115.66, and 154.60 keV, have been obtained.

  17. The EU's Convergence Dilemma

    Full Text Available As economic stagnation continues to mark the EU in the fifth year of the euro zone crisis, political support for integration is waning. The European Parliament elections of 2014 returned a hitherto unparalleled number of Eurosceptic MEPs, with EU-critical parties becoming the largest ones in several Member States. Much of this Euroscepticism is driven by economic polarisation between core and peripheral countries. While an increasing number of voters in the northwestern creditor countries resent having to foot the bill for what they consider economic mismanagement in the periphery, voters in peripheral countries increasingly rebel against what they deem to be an economically catastrophic Diktat from Germany and its allies. Continued political support for European integration will hinge on successful income convergence in the EU but the current dilemma is that such policies might not be politically feasible. Periods of rapid convergence would seem to suggest that success depends on two main policy strategies. First, a monetary policy that promotes credit for productive purposes, leaves inflation control to other instruments, and employs selective credit rationing to prevent asset booms. Second, a vertical industrial policy prioritising selected industrial sectors. The first policy conflicts with the present framework of euro zone monetary policy, but that framework was only installed in the first place because many peripheral countries were desperately in search of an external constraint on domestic distributional conflict. Industrial policies, in turn, require a sufficient degree of state autonomy from business elites in order to be effective, but it is highly questionable whether most states in the EU possess such autonomy. Though there are, as yet hesitant, signs of a reorientation of both monetary and cohesion policy in the EU, the question of the institutional and political preconditions for their successful implementation has been largely

    The {sup 57}Fe Moessbauer spectroscopy is a nuclear, non-destructive technique used for the investigation of structural, magnetic and hyperfine properties of several materials. It is a powerful tool in characterizing materials in physics, metallurgy, geology and biology field areas, especially magnetic materials, alloys and minerals containing Fe. Lately, the Conversion Electron Moessbauer Spectroscopy (CEMS) is widely used in making studies on ultra-thin magnetic films, as well as other nanostructured materials. In case of magnetic nanostructures, low temperature (LT) studies are especially important due to the possibility of dealing with superparamagnetic effects. In this work it was developed a CEMS measurement system for low temperatures (<20 K) based on a solid-state electron multiplier (Channeltron{sup R}) and an optical cryostat (Model SVT-400, Janis Research Co, USA), from which the project was originally conceived at the Applied Physics / Moessbauer spectroscopy Department from University of Duisburg-Essen, Germany.

To answer...... this question, one must first take a step back. Trade policy is only one of many areas in the EU. And human rights in trade is one of the latest developments. The earliest development came originally within the EU itself and related to the absorption of Portugal and Spain in the 70s and 80s. The country had...... no tradition of democracy, the EU insisted that they adopted a certain level of human rights. At about the same time there was an innovation in development policy and a desire to link development aid with the promotion of human rights. Only then began to find a way into trade policy. Historically, the EU...

    Full Text Available VAT is one of the newest tools of the global economy and is widely adopted in most of the countries. For EU Member States is required not only the existence of VAT, but also that its main characteristics to be uniformly implemented. This should facilitate intra-Community transactions, but in practice does not as there are many local variations which can lead to costly errors and penalties. The objective of this paper is to collate data about the main characteristics of VAT in EU Member States and to highlight the key differences between them. This survey shows that there continue to be opportunities and risks for businesses trading cross border, as a result of differences in application of Community legislation on VAT. This led to the necessity of VAT reform. On this basis, the Commission adopted on the end of the last year a Communication on the future of VAT. This sets out the fundamental characteristics that must underlie the new VAT regime, and priority actions needed to create a simpler, more efficient and more robust VAT system in the EU.

    In September 2004 David Shambaugh, of George Washington University, published a small article under the heading: “China and Europe: The Emerging Axis.” In his view, one “of the most important, yet least appreciated developments … has been the dramatic growth in ties between China and Europe......” (Shambaugh 2004, 243). He pointed, firstly, at the strong growth in trade relations; the EU also became the largest foreign supplier of technology and equipment, in the form of direct investment, but also through a number of joint technology projects. The EU-China Framework Program became the world’s largest...... is impressive.” To be sure, there were also points of frictions such as the European arms embargo (introduced after the Tianmen massacre in 1989), but Shambaugh saw it as highly likely that the relationship between EU and China would continue to grow and develop. “Over time it will become a new axis in world...

  11. Neutron capture cross sections of 151,153Eu

    International Nuclear Information System (INIS)

    The neutron capture cross section of 151,153Eu nuclei was measured using the Detector for Advanced Neutron Capture Experiments (DANCE) at the Los Alamos Neutron Science Center (LANSCE). Neutrons were produced at the Lujan Neutron Scattering Center and their energies were determined by the time-of-flight technique. The relative yield versus neutron incident energy from 0.1 eV to 2.0 keV for both 151Eu(n,) and 153Eu(n,) reactions was derived from events gated on the total energy and multiplicity measured by the DANCE array. The absolute cross section was determined by scaling the relative yield to the measured cross sections of well-known resonances. The shape of the yield curve agrees well with previous measurements in the resonance region for both 151Eu and 153Eu capture cross sections. New data are reported for neutron incident energies between 100 eV and 2.0 keV. The trend of data in the 0.3 keV to 2.0 keV region of neutron incident energy is consistent with the ENDF/BVI and the measurements of Macklin and Young. Crucial skills, acquired from these measurements in the early implementation of DANCE, are important to plan future experiments, which will yield results up to a few hundred keV neutron incident energy

    We investigated Eu3+ and Eu2+ ion incorporation and the reduction of Eu3+ ions in a LiBaPO4 lattice using atomistic simulations based on lattice energy minimization. We predicted the most probable sites occupied by Eu3+ and Eu2+ ions, and the related charge-compensation mechanisms involved in these substitutions to the most provable reduction agent for Eu reduction. It was found that Eu3+and Eu2+ ions are the most energetically favorable for incorporation at Ba site. In the case of the Eu3+ ion, charge compensation by the LiBa‧ antisite is the most provable. Eu3+ reduction involving a H2 reduction atmosphere is the most favorable. Our results reveal that Eu3+ and Eu2+ position plays an important role in the luminescence characteristic and in the persistent luminescence mechanisms related to LiBaPO4.

    Full Text Available This article analyzes the link between culture and diplomacy between Russia and the European Union, and shows the importance of cultural relations. It examines the common space of science, education and culture introduced at the 2003 EU-Russia Summit in St. Petersburg and the application of the principles of this concept that were established at the 2005 EU-Russia Summit in Moscow. It then considers EU-Russia collaboration on humanitarian action and the challenges that both parties face in this sphere. It also explains the formation of EU domestic and foreign cultural policy, and the role of European institutions and states in cultural affairs and diplomacy, as well as key elements and mechanisms of contemporary Russian foreign cultural policy. In addition, the article focuses on the European side of post-Soviet EU-Russia cultural relations. This cultural collaboration is defined as a competitive neighbourhood. EU and Russian interests collide: while Europeans try to promote their values, norms and standards within the framework of the European Neighbourhood Policy, Russia seeks to culturally influence and engage in this region for geostrategic and historical reasons. Finally, the article assesses the prospects for the EU-Russia cultural relations and emphasizes the role of ideology in improving such relations.

The paper wants to outline which future EU draws for the city, through an integrated and contextual reading of addresses and strategies contained in the last documents, a future often suggested as Smart City. Although the three main documents (Cohesion Policy 2014-2020 of European Community, Digital Agenda for Europe and European Urban Agenda face the issue of the future development of European cities from different points of view, which are respectively cohesion social, ICT and urban dimension, each of them pays particular attention to urban and territorial dimension, identified by the name of Smart City. In other words, the paper aims at drawing the scenario of evolution of Smart Cities that can be delineated through the contextual reading of the three documents. To this end, the paper is divided into three parts: the first part briefly describes the general contents of the three European economic plan tools; the second part illustrates the scenarios for the future of the European city contained in each document; the third part seeks to trace the evolution of the Smart Cities issue developed by the set of the three instruments, in order to provide the framework of European Community for the near future of our cities.

    Good eyesight is often taken for granted, a situation that everyone appreciates once vision begins to fade with age. New eyeglasses or contact lenses are traditional ways to improve vision, but recent new technology, i.e. LASIK laser eye surgery, provides a new and exciting means for marked vision restoration and improvement. In mass spectrometry, detectors are the 'eyes' of the MS instrument. These 'eyes' have also been taken for granted. New detectors and new technologies are likewise needed to correct, improve, and extend ion detection and hence, our 'chemical vision'. The purpose of this report is to review and assess current MS detector technology and to provide a glimpse towards future detector technologies. It is hoped that the report will also serve to motivate interest, prompt ideas, and inspire new visions for ion detection research.

    The 155Eu nuclide was investigated by the directional angular correlation technique following the β decay of 155Sm. The angular correlation measurements were carried out using a setup with 4 Ge detectors and a multi parametric data acquisition system. To perform the data analysis a new methodology was developed . The multipole mixing ratios of twenty sixty γ- transitions were determined. Seven of them agreed with the results of earlier angular correlation studies and nineteen obtained for the first time confirmed the multipolarity suggested in earlier electron capture studies. Besides, the spin of the level at 1106.83 keV as well as the parity of the level at 1301.41 keV have also been suggested. The nuclear structure of 155Eu was discussed successfully in terms of the single particle model using a deformed Woods-Saxon potential plus residual pairing interaction permitting the description of the rotational quasi-proton band heads.

    1995-10-01

    J. Seguinot and T. Ypsilantis have recently described the theory and history of Ring Imaging Cherenkov (RICH) detectors. In this paper, I will expand on these excellent review papers, by covering the various photon detector designs in greater detail, and by including discussion of mistakes made, and detector problems encountered, along the way. Photon detectors are among the most difficult devices used in physics experiments, because they must achieve high efficiency for photon transport and for the detection of single photo-electrons. For gaseous devices, this requires the correct choice of gas gain in order to prevent breakdown and wire aging, together with the use of low noise electronics having the maximum possible amplification. In addition, the detector must be constructed of materials which resist corrosion due to photosensitive materials such as, the detector enclosure must be tightly sealed in order to prevent oxygen leaks, etc. The most critical step is the selection of the photocathode material. Typically, a choice must be made between a solid (CsI) or gaseous photocathode (TMAE, TEA). A conservative approach favors a gaseous photocathode, since it is continuously being replaced by flushing, and permits the photon detectors to be easily serviced (the air sensitive photocathode can be removed at any time). In addition, it can be argued that we now know how to handle TMAE, which, as is generally accepted, is the best photocathode material available as far as quantum efficiency is concerned. However, it is a very fragile molecule, and therefore its use may result in relatively fast wire aging. A possible alternative is TEA, which, in the early days, was rejected because it requires expensive CaF{sub 2} windows, which could be contaminated easily in the region of 8.3 eV and thus lose their UV transmission.

The image noise in photon counting systems is investigated theoretically and experimentally and is shown to be given by Poisson statistics. The rate capability of the LAD1 was measured to be 250 kHz per pixel. Theoretical and experimental studies of the difference in contrast for ideal charge integrating and photon counting imaging systems were carried out. It is shown that the contrast differs and that for the conventional definition (contrast = (background - signal)/background) the photon counting device will, in some cases, always give a better contrast than the integrating system.

    Detectors used for gamma spectrometry must be calibrated for each geometry considered in environmental radioactivity laboratories. This calibration is performed using a standard solution containing gamma emitter sources. Nevertheless, the efficiency curves obtained are periodically checked using a source such as {sup 152}Eu emitting many gamma rays that cover a wide energy range (20-1500 keV). {sup 152}Eu presents a problem because it has a lot of peaks affected by True Coincidence Summing (TCS). Two experimental measures have been performed placing the source (a Marinelli beaker) at 0 and 10 cm from the detector. Both spectra are simulated by the MCNP 4C code, where the TCS is not reproduced. Therefore, the comparison between experimental and simulated peak net areas permits one to choose the most convenient peaks to check the efficiency curves of the detector.

  6. Synthesis and luminescence of Eu3+ doped hydroxyapatite nanocrystallines: Effects of calcinations and Eu3+ content

    International Nuclear Information System (INIS)

    Eu3+ doped hydroxyapatite (Eu-HAP) luminescent nanocrystallines were prepared by ultrasound assisted precipitation method. Aiming to seek a compromise proposal for achieving high luminescence and nanocrystallines, the effects of calcinations temperature and Eu3+ doping content on luminescence property as well as phase composition, crystal size and crystallinity of Eu-HAP crystals were investigated. The results showed that the luminescence of Eu-HAP was enhanced by the thermal treatment and the increasing Eu doping content. However, the higher temperature and the excess Eu resulted in the size increase and phase composition change of HAP respectively. The 2% Eu doping content and calcinations temperature of 600 °C were preferred for preparing Eu-HAP nanocrystallines with strong luminescence. The Eu-HAP nanocrystallines were about 20–40 nm in diameter (TEM) and could be well dispersed in water to form aqueous suspension of about 140 nm (DLS intensity-averaged diameter). Eu-HAP nanocrystalline could be used as a fluorescent probe for cell labeling. - Highlights: ► 20–40 nm Eu-HAP luminescent nanocrystallines were prepared by the precipitation method. ► 2% Eu doping content and calcinations at 600 °C were preferred to prepare Eu-HAP. ► Eu-HAP nanocrystallines could be well dispersed to form aqueous suspension. ► Eu-HAP nanocrystallines could be used as cell labels.

  12. Intrinsic radioactivity of KSr2I5:Eu2+

    Science.gov (United States)

    Rust, M.; Melcher, C.; Lukosi, E.

    2016-10-01

    A current need in nuclear security is an economical, yet high energy resolution (near 2%), scintillation detector suitable for gamma-ray spectroscopy. For current scintillators on the market, there is an inverse relationship between scintillator energy resolution and cost of production. A new promising scintillator, KSr2I5:Eu2+, under development at the University of Tennessee, has achieved an energy resolution of 2.4% at 662 keV at room temperature, with potential growth rates exceeding several millimeters per hour. However, the internal background due to the 40K content could present a hurdle for effective source detection/identification in nuclear security applications. As a first step in addressing this question, this paper reports on a computational investigation of the intrinsic differential pulse height spectrum (DPHS) generated by 40K within the KSr2I5:Eu2+ scintillator as a function of crystal geometry. It was found that the DPHS remains relatively equal to a constant multiplicative factor of the negatron emission spectrum with a direct increase of the 1.46 MeV photopeak relative height to the negatron spectrum with volume. Further, peak pileup does not readily manifest itself for practical KSr2I5:Eu2+ volumes.

  13. Radioactive contamination of SrI2(Eu) crystal scintillator

    International Nuclear Information System (INIS)

    A strontium iodide crystal doped by europium (SrI2(Eu)) was produced by using the Stockbarger growth technique. The crystal was subjected to a characterization that includes relative photoelectron output and energy resolution for γ quanta. The intrinsic radioactivity of the SrI2(Eu) crystal scintillator was tested both by using it as scintillator at sea level and by ultra-low background HPGe γ spectrometry deep underground. The response of the SrI2(Eu) detector to α particles (α/β ratio and pulse shape) was estimated by analysing the 226Ra internal trace contamination of the crystal. We have measured: α/β=0.55 at Eα=7.7MeV, and no difference in the time decay of the scintillation pulses induced by α particles and γ quanta. The application of the obtained results in the search for the double electron capture and electron capture with positron emission in 84Sr has been investigated at a level of sensitivity: T1/2∼1015–1016yr. The results of these studies demonstrate the potentiality of this material for a variety of scintillation applications, including low-level counting experiments.

    A neutron detector has a volume of neutron moderating material and a plurality of individual neutron sensing elements dispersed at selected locations throughout the moderator, and particularly arranged so that some of the detecting elements are closer to the surface of the moderator assembly and others are more deeply embedded. The arrangement captures some thermalized neutrons that might otherwise be scattered away from a single, centrally located detector element. Different geometrical arrangements may be used while preserving its fundamental characteristics. Different types of neutron sensing elements may be used, which may operate on any of a number of physical principles to perform the function of sensing a neutron, either by a capture or a scattering reaction, and converting that reaction to a detectable signal. High detection efficiency, an ability to acquire spectral information, and directional sensitivity may be obtained.

Some authors have wondered if this concept is a fashion, comprising some older ideas and principles, while other authors have asserted that the reasons why different methods of governance appear in the EU are based on “the complexity and the uncertainty of the problems on the agenda, an irreducible, the new approaches on public administration and law, hidden competencies, legitimacy and subsidiarity”. At a normative level, the White Paper of European Governance consecrated five principles on which good governance is based upon: openness, participation, responsibility, efficiency and coherence.

    Full Text Available The issue of admissibility of evidence has been regulated only very scarcely in the EU. Judicial cooperation in criminal matters has been embracing the increasing number of instruments, covering plethora of aspects, however, the field of admissibility of evidence remains almost untouched. Can the Area of Freedom, Security and Justice be called the Common Evidence Area? From the national perspective, the issue of admissibility of evidence is still subject to divergent solutions in the Member States, concerning the common law and continental law systems, i.e. the right of access to a lawyer. Thus, the paper aims to take into account the tendencies of legal rule in matter of admissibility of evidence, the dynamic of evidence movement within EU area.

    As in previous years, an intercomparison of passive radon detectors was held at NRPB in 2001. Forty-seven laboratories submitted 62 sets of passive detectors to this intercomparison. The exercise included three exposures to radon and its decay products at different equilibrium factors. An additional exposure at the CERN - EU high Energy Reference Facility (CERF) to a simulated cosmic ray spectrum was also offered to participants. After exposure, the detectors were returned to their originating laboratories for assessment. Participants reported the estimated exposure for each detector before they were notified of the exposures given to the detectors. The results obtained by participating laboratories were classified according to the spread of results from detectors exposed together and by the difference between the mean result of each group and the actual exposure given. Thirty-five percent of the laboratories achieved the highest classification for accuracy, while 9% were in the lowest category. The proportio...

  2. Governance in EU illicit drugs policy.

    Science.gov (United States)

    Edwards, Carel; Galla, Maurice

    2014-09-01

    This commentary represents the authors' views on EU governance in illicit drug policy, a field in which they were active for more than 10 years between them. EU drug policy has a narrow legal basis in the European Treaties and is mostly non-binding. The main policy instruments are 8-year EU Drug Strategies, underpinned by 4-year Action Plans which set out specific objectives at national, EU or international level. The approach that guides EU drug policy is known as the 'balanced approach'. It is remarkably restrained and reflects the reality that very few Member States have either the socio-political culture or the resources to consistently apply the punitive sanctions foreseen by the UN conventions. An important feature of EU governance in the field of drugs is the proactive support that is provided to non-governmental organisations both within the EU as well as in accession, associated or third countries. At a global level, the EU is a major financial aid donor also in this field. This position is not however reflected in corresponding political clout for the EU within the UN system. EU governance on drugs has made it possible for many of its Member States to accommodate the problem rather than to "solve" what by all the evidence from the last 100 years may well be insoluble, at least by means of criminalisation and prohibition. The big question is where EU drug policy is headed in the next few years. The EU has been promoting measures and practices that target real problems. It has done so without indulging too much in unhelpful rhetoric. However, like all successful formulae this one also has a sell-by date. EU governance in the field of drugs cannot afford to stand still. It needs to find a second wind.

  8. Issues Related to EU's Foreign Policy

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    @@ The European Union (EU) is widely regarded as an important international actor, and usually referred to as a big power like the U. S. , Russia, China and Japan. So naturally the foreign policy of the EU has caught attention of both officials and scholars over the world. However, the EU is also a combination of sovereign states, its foreign policy is different from others, and perhaps this is often ignored. For instance, unlike a single nation state, the EU's influence and power are different in various policy fields due to its different ways of decision-making and implementation. Also, different from the common currency, the forming of the common foreign policy of the EU doesn't mean the disappearance of respective member state's foreign policy. Only seeing or emphasizing one respect will lead to a misunderstanding of the EU. Moreover, as a unique "supranational and intergovernmental" organization in the world, the EU has too many complex institutions, names and terms. Of course, the situation is not better in the field of foreign policy, and it easily leads to confusion and misunderstanding. It is also necessary to point out that the EU is still in the process of evolvement, and in particular, as one of the major reforms of the EU in recent years, the foreign policy-making mechanism has been in the center of change and adjustment. It is no doubt that this adds to the difficulties of studying and understanding the EU's foreign policy. In a word, the author thinks it is necessary to raise some major issues related to the EU's foreign policy and delve into it in connecting with the EU's current development.

    Neutron capture for incident neutron energies <1eV up to 100 keV has been measured for {sup 151,153}Eu targets. The highly efficient DANCE (Detector for Advanced Neutron Capture Experiments) array coupled with the intense neutron beam at Los Alamos Neutron Science Center is used for the experiment. Stable Eu isotopes mass separated and electroplated on Be backings were used. Properties of well-resolved, strong resonances in two Eu nuclei are examined. The parameters for most of these resonances are known. Detailed multiplicity information for each resonance is obtained employing the high granularity of the DANCE array. The radiative decay cascades corresponding to each resonance are obtained in the experiment. The measurements are compared to simulation of these cascades which calculated with various models for the radiative strength function. Comparison between the experimental data and simulation provides an opportunity to investigate the average quantities.

    Cooperative performance of mixed-valent Eu(2+) /Eu(3+) in single-compound phosphors offers significant advantages in color rendering and luminescence efficiency, but their synthesis is challenging because of Eu(2+) oxidation. Using the tunable nature of the metal-ion nodes in metal-organic frameworks (MOFs), we present an in situ reduction and crystallization route for preparing MOFs and doping Eu(2+) /Eu(3+) with a controlled ratio. These materials exhibit rich photoluminescence, including intrinsic- and sensitized-emissions of Eu(2+) and Eu(3+) , and long-lived luminescence from charge transfer. Color rendering can be easily achieved by fine-tuning the valence states of Eu. A linear relation between temperature and the intensity ratio of Eu(2+) /Eu(3+) emissions provides outstanding properties for applications as self-calibrated luminescent thermometers with a wide working temperature range. Further incorporation of Tb(3+) into the MOFs results in white light, utilizing all Eu(2+) ,Tb(3+) , and Eu(3+) emissions in a single crystalline lattice. PMID:27305606

  3. Renewable energies in the EU

    International Nuclear Information System (INIS)

    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.)

  4. EU environmental policy and competitiveness

    2006-01-01

    Full Text Available Protection of the environment was not a specific importance to the Community although the Treaty of Rome expressly specified that "health, safety environmental protection" shall be based on "a high level of protection". In deciding upon a framework for a European environmental policy, the Community was also responding to increased public awareness of the problem and concerns about the state of the natural and man-made environment. During the past years, competitiveness concerns have dominated the EU policy debate, in the course of which a growing consensus is being developed on the importance of eco-innovations and resource efficiency for EU competitiveness and on the market opportunities they offer. There is an increasing evidence that environmental policy and eco-innovations can promote economic growth, as well as maintain and create jobs, contributing both to competitiveness and employment. Environmental constraints to rapid economic growth are increasingly recognized by countries, leading to a rising awareness of the need for sustainable development. Implementation of an environmental policy however, generates significant implications for competition among countries.

    Nanocrystallic europium-activated lutetium oxide (Lu{sub 2}O{sub 3}:Eu) is a strong candidate for use in digital medical imaging applications, due to its spectroscopic and structural properties. The aim of the present study was to investigate the imaging and efficiency properties of a 33.3 mg/cm{sup 2} Lu{sub 2}O{sub 3}:Eu scintillating screen coupled to a high resolution RadEye HR CMOS photodetector under radiographic imaging conditions. Since Lu{sub 2}O{sub 3}:Eu emits light in the red wavelength range, the light emission efficiency and the imaging performance were compared with results for a Gd{sub 2}O{sub 2}S:Eu phosphor screen. Parameters such as the Absolute Efficiency (AE), the X-ray Luminescence Efficiency (XLE), and the Detector Quantum Gain (DQG), were investigated. The imaging characteristics of Lu{sub 2}O{sub 3}:Eu nanophosphor screen were investigated in terms of the Modulation Transfer Function (MTF), the Normalized Noise Power Spectrum (NNPS) and the Detective Quantum Efficiency (DQE). It was found that Lu{sub 2}O{sub 3}:Eu nanophosphor has higher AE and XLE by a factor of 1.32 and 1.37 on average, respectively, in the whole radiographic energy range in comparison with the Gd{sub 2}O{sub 2}S:Eu screen. DQG was also found higher in the energy range from 50 kVp to 100 kVp and comparable thereafter. The imaging quality of Lu{sub 2}O{sub 3}:Eu nanophosphor coupled to the CMOS sensor was found to outmatch in any aspect in comparison with the Gd{sub 2}O{sub 2}S:Eu screen. These results indicate that Lu{sub 2}O{sub 3}:Eu nanophosphor could be considered for further research in order to be used in medical imaging applications. - Highlights: • AE and XLE of Lu{sub 2}O{sub 3}:Eu nanophosphor were higher by a factor of 1.32 and 1.37 than Gd{sub 2}O{sub 2}S:Eu. • DQG was higher from 50 to 100 kVp and comparable thereafter. • Imaging performance of Lu{sub 2}O{sub 3}:Eu/CMOS was better than that of Gd{sub 2}O{sub 2}S:Eu/CMOS.

  6. MCNP Analysis and Optimization of a Triple Crystal Phoswich Detector

    International Nuclear Information System (INIS)

    Researchers at the University of Missouri-Columbia have designed a triple crystal phoswich detector that allows for simultaneous detection of alpha, beta, and gamma radiation. A ZnS:Ag layer detects alpha particles, a CaF2:Eu scintillator preferentially interacts with beta particles, and a NaI:Tl cell is used for gamma detection. The detector output is digitally collected, processed, and analyzed by a personal computer using custom software. MCNP simulations of this detector found that the phoswich design has inherent minimum energy limits of 250 keV Emax for beta particles and 50 keV for gamma-rays. For a 2.54 cm thick NaI:Tl crystal, intrinsic gamma efficiency for photons ranges from a maximum of 80% at 100 keV to 26% for 2 MeV photons. Mischaracterized gamma events in the CaF2:Eu crystal above 175 keV can be corrected by subtracting 26 +/- 4% of the total number of counts in the NaI:Tl crystal from the CaF2:Eu response. Beta induced events in the NaI:Tl crystal primarily result from Bremsstrahlung interactions and can be estimated by multiplying the CaF2:Eu energy spectrum by a normalizing factor

  14. Intra-EU Direct Investment and Enlargement

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available This paper examines the determinants of the intra-EU direct investment (IDI into the New Member States (NMS using a panel dataset of bilateral capital flows for the period 1993-2013. It is found out by using a simple gravity model that EU membership is the most important determinant. Unlike previous studies including non-EU countries, the distance is insignificant, which is caused by proximity of these countries to one another. A separate analysis focused on subgroups of accession countries gives some evidence that even when size of their economy, distance, institutional quality and EU accession are taken into account, Central European countries receive more IDI than the Baltic and the Balkan states. On the contrary to that, the analysis restricted to the Balkan countries which have joined the EU shows the inexistence of a negative Balkans effect in attracting foreign investment. This finding is relevant because previous studies demonstrate a persistent negative Balkans effect for non-EU Balkan countries and suggests a crucial impact of the EU accession in determining the intra-EU capital flows.

    The EU's strategy for Russia since the end of the cold war has to a large extent failed, and the direct consequences are the currently deadlocked EU-Russia relationship. There are three reasons for this: the EU and Russia's respective strength and status relative to each other have been changing since the beginning of this century; the EU's strategy towards Russia has been more fragmenting in recently years; and the American factor. The EU-Russia relations could continue to be in poor shape in the years to come, and it is very likely sometimes even further worsening. But the two sides would refrain from extreme measures and prevent their relations from sliding into real cold war.

The missing 8 (4 in YB-1 and 4 in YB-2) chambers can be installed only after the lowering of the two wheels into the UX cavern, which is planned for the last quarter of the year. Cabling on the surface of the negative wheels was finished in May after some difficulties with RPC cables. The next step was to begin the final commissioning of the wheels with the final trigger and readout electronics. Priority was giv¬en to YB0 in order to check everything before the chambers were covered by cables and services of the inner detectors. Commissioning is not easy since it requires both activity on the central and positive wheels underground, as well as on the negative wheels still on the surface. The DT community is requested to commission the negative wheels on surface to cope with a possible lack of time a...

For the author, the experience of ECHO shows the "limits of what is humanitarian": that is, the lack of security for humanitarian workers, the still-to-beoperational Permanent Tribunal for Crimes Against Humanity, the difficult access to refugees, and the fact that humanitarian efforts are not a substitute for policy and, therefore, that humanitarian efforts can not resolve a crisis that has a political origin and solution. The challenges to be faced in the coming years include denouncing the violations of humanitarian values, transferring these values into a future CFSP, organizing humanitarian aid efficiently, combating “donor fatigue” and supporting conflict prevention.

  8. Characterization of the lanthanum chloride scintillation detector

    International Nuclear Information System (INIS)

    This paper reports about the investigations on the performance of the new earth-rare halide Scintillator, the LaCl3:10%Ce, which has been discovered with attractive scintillation properties: fast, efficient, and high-energy resolution. The combination of good brightness and linear response has naturally resulted in a very good energy resolution, whereas the fast decay time promoted counting applications at very high rate and very fast timing resolution. Energy resolutions of (2.99±0.02) %, (8.66±0.02) %, and (2.05±0.01) % have been achieved by exciting the detector with 662 keV 137Cs, 122 keV 152Eu, and 1332.5 keV 60Co sources respectively, at room temperature. The variations of the resolution as a function of both shaping time and high voltage have been studied and found to be relatively linear. The timing resolution was also studied. The value of 1.07 ns FWHM has been recorded with LaCl3:10%Ce and BaF2 detectors operating in coincidence mode, using 1333.5 keV γ-ray 60Co peak. Compared to similar studies, this timing resolution was worse than expected even if the exciting radioactive sources used in the two experiments were different. The efficiency values of (0.24±0.01)%, (0.01±0.01)% and (0.09±0.01)% were obtained with laboratory 137Cs, 152Eu, 60Co isotopes respectively. These detector efficiency values were very low, due to the smaller detector sizes used in these earlier crystals and to the large detector-source-distance used in this experiment. The Lanthanum Chloride Scintillator detector is hygroscopic and relatively expensive compared to established scintillators. In addition, it carries internal contamination in 138La and 227Ac for larger thicknesses. Nevertheless, the energy resolution figures achieved, twice as good as that of NaI(Tl), are in good agreement with those reported elsewhere. They credit the scintillation detectors as good challengers of semiconductor-based detectors, allowing their application fields to be extended. (author)

  10. Normative power Europe? EU relations with Moldova

    Directory of Open Access Journals (Sweden)

    Tessa de Wekker

    2010-10-01

    Full Text Available This article analyses the extent to which the European Union (EU constitutes a normative power in its relations with Moldova. ‘Normative power Europe’ is examined along three dimensions: (i normative intent; (ii normative process; and (iii normative impact. Our empirical analysis focuses on two norms: democracy and good governance. In addition, we ask how ‘normatively’ the EU has acted regarding a solution to the Transnistrian conflict. On the basis of our three-dimensional framework, we find that EU normative power can be judged as only moderate in EU-Moldovan relations. As for intent, while norms of democracy and good governance seem to play a central role in EU-Moldovan relations, the Union tends to apply double standards in terms of what it expects from (EU Member States and what it asks of Moldova, and also seems to be inconsistent in its policies towards Moldova and Ukraine. In terms of process, the degree of inclusiveness on the part of the Union has not been satisfactory. Neither has the extent of reflexivity, but more recently the Commission seems to have developed a more reflexive behaviour. In regards to impact, while norm changes in Moldova have been modest/moderate, it seems that the EU has substantially contributed to these changes.

    We succeeded in growing single crystals of the ferromagnets EuPd2 and EuPt2 with the Laves-type cubic structure by the Bridgman method, namely, heating constituting materials in a Mo crucible up to a high temperature of about 1500 °C. The ferromagnetic properties of EuPd2 and EuPt2 with Curie temperatures of 74 and 100 K, respectively, were confirmed from the results of electrical resistivity, specific heat, and magnetization measurements. The ordered moment is 7 μB/Eu, revealing the Eu-divalent ferromagnetism. The present Eu-divalent electronic state is found to be robust against high pressures of up to 8 GPa and is not changed into the Eu-trivalent state. We also carried out de Haas-van Alphen (dHvA) experiments for EuPd2. The detected dHvA branches in EuPd2 are well explained by the relativistic linearized augmented plane wave (RLAPW) energy band calculations for SrPd2, revealing a closed hole Fermi surface and compensated four closed electron Fermi surfaces.

  12. Emerging food safety issues: An EU perspective.

    Science.gov (United States)

    McEvoy, John D G

    2016-05-01

    Safe food is the right of every citizen of the European Union (EU). A comprehensive and dynamic framework of food and feed safety legislation has been put in place and the EU's executive arm - the European Commission - is responsible for ensuring that the EU member states apply food law consistently. Similarly, the Commission plays an important role in ensuring that imported food meets the EU's stringent food safety standards. Consumer perceptions of unsafe food tend to focus on acute outbreaks of bacterial or viral origin. In recent years there have been a number of diverse food crises associated with fraudulent activity which may (e.g. melamine in dairy products in China) or may not (e.g. the horse meat scandal in the EU) represent a genuine food safety risk. Well publicized incidents of chronic exposure to chemical contamination in the EU (e.g. dioxins in meat and mycotoxins in nuts) have required robust coordinated policy responses from the Commission. Despite the decreasing incidence of non-compliant residues of veterinary medicinal products and banned substances in animal products, EU consumers are increasingly concerned about the use of such products in food-producing animals, including in the context of the build-up of antimicrobial resistance in animals and transfer to humans. The Commission plays a key role in coordination of the EU member states' responses to such incidents, in risk management, and in preparation for emerging issues. This paper focuses on how the EU as a whole has dealt with a number of food crises, and what can be learned from past incidents. Copyright © 2016 John Wiley & Sons, Ltd. PMID:27443205

    Full Text Available On average, EU countries allocate 6.4% of total public expenditure for the direct support of the public sector at all levels of education. In view of a more rational allocation of resources seriously diminished by the crisis there are made efforts to identify educational areas considered problematic in terms of accessing various education programs. This paper presents pre-school funding policies and policies to support families with preschool and school age children in the European Union through a comparative analysis of the focus group type. There are also presented concrete ways of achieving that family support such as tax cuts, family allowances or by taking into account certain factors in order to establish fees. In all countries where taxes are paid for pre-compulsory education (ISCED A there is a mechanism by which parental contributions can be adjusted according to the means available taking into account criteria such as family income, number of children, family status (children who live with one parent geographic area, etc.

    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.

    Full Text Available The paper answers at two important questions: Is the EU able to support new adhering processes? and Is the Euro area able to enlarge in 2014? The comparative analysis in the paper covers four economic competitors: EU, USA, China and Japan, and is based on GDP growth rate, unemployment and inflation rates. The second part of the paper deals with an economic forecast during 2015-2016, focused on EU27, Euro area, Croatia and Latvia, in order to discuss the effects of the adhering to EU and Euro area. The results of the two-level analysis are supported by pertinent diagrams and annexes. The analysis uses a neutral statistical database – Eurostat – and dedicated forecast software. The main conclusion of the paper is that the adhering processes from 2013 and 2014 are based on economic and political criteria.

    The Gamma Detector Response and Analysis Software (GADRAS) applies a Detector Response Function (DRF) to compute the output of gamma-ray and neutron detectors when they are exposed to radiation sources. The DRF is fundamental to the ability to perform forward calculations (i.e., computation of the response of a detector to a known source), as well as the ability to analyze spectra to deduce the types and quantities of radioactive material to which the detectors are exposed. This document describes how gamma-ray spectra are computed and the significance of response function parameters that define characteristics of particular detectors.

    2010-12-01

    Full Text Available China’s investments in the European Union are much lower than what you may expect given the economic size of both entities. These relatively low investments in Europe are a combination of priority and obstacles. The priority for investments is clearly in Asia, Africa and Latin America. This regional pattern is heavily influenced by the need to solve the resource shortage in the medium and long term. The investments in Europe and the United States are mostly market seeking investments. Research specifically focused on Chinese M&A abroad comes to the same conclusion. The success rate of Chinese M&A abroad is much lower than what we see with respect to American or European investments abroad. In this paper, we examine why Chinese firms are facing more difficulties in the European Union than in other regions. The paper focuses on Chinese M&A as proxy for total foreign direct investments abroad. By looking at the factors that have been documented as influencing the level of M&A abroad, it becomes clear that Chinese firms in Europe are hindered by many factors. For example, the trade between China and the EU is relatively low, the institutional quality is lower compared to the United States, there is less experience with respect to Europe and relatively many deals relate to State Owned Enterprises (SOE which makes the deal sensitive. So it is logical that Chinese investments are not very high in Europe. However, the research makes clear that the obstacles for Chinese investments in Europe are disappearing step by step. In that sense, we expect a strong increase of Chinese investments in Europe in the future.

    Childress, N L

    2002-01-01

    Researchers at the University of Missouri-Columbia have designed a triple crystal phoswich detector that allows for simultaneous detection of alpha, beta, and gamma radiation. A ZnS:Ag layer detects alpha particles, a CaF sub 2 :Eu scintillator preferentially interacts with beta particles, and a NaI:Tl cell is used for gamma detection. The detector output is digitally collected, processed, and analyzed by a personal computer using custom software. Monte Carlo N-Particle version 4C simulations of this detector found that the phoswich design has inherent minimum energy limits of 250 keV E sub m sub a sub x for beta particles and 50 keV for gamma-rays. For a 2.54 cm thick NaI:Tl crystal, intrinsic gamma efficiency for photons ranges from a maximum of 80% at 100 keV to 26% for 2 MeV photons. Mischaracterized gamma events in the CaF sub 2 :Eu crystal above 175 keV can be corrected by subtracting 26+-4% of the total number of counts in the NaI:Tl crystal from the CaF sub 2 :Eu response. Beta induced events in the N...

    The lattice site location of excited states of $^{149}$Eu was studied by means of the emission channeling technique. 60 keV implantation of $^{149}$Tb into a GaN thin film was performed at room temperature up to a dose of 2.0 $\\times 10^{13}$ cm$^{-2}$. This radioactive isotope eventually decays into short-lived excited states of $^{149}$Eu. The conversion electrons emitted in the subsequent decay to the $^{149}$Eu ground state were detected with a position sensitive detector. We measured their angular distributions around the [0001], [1102], [1101] and [2113] axes in the as-implanted state and after 600°C and 900°C vacuum annealing. Already in the as-implanted state around 65% of $^{149^{*}}$Eu atoms were found on substitutional Ga sites. The root mean square (rms) displacements from the substitutional sites in the as-implanted state were found to be around 0.13-0.16 . Annealing up to 600$^\\circ$C increased the substitutional fraction by a few percent and slightly reduced the rms displacements, most likely...

  8. Succession of States in the EU

    Full Text Available A specter is haunting Europe – the specter of separatism. Scotland, Catalonia, Flanders, South Tyrol – all these regions have separatist movements pursuing independence from their current National State. The breakup of an EU Member State no longer seems impossible. To date, it is unclear what impact this would have on the EU membership of the new entities (with consequences for the character of citizenship, voting rights in the council, number of MEPs etc. that emerge from the old States. The common rules of Public International Law governing the succession of States are insufficient in the case of a succession of States in the EU. Although the Treaties do not provide for such a situation and the past 60 years of European history offer only a few and not really persuasive precedents, the nature of the EU as a joint association of sovereign States (“Staatenverbund” demands a special approach: A separated State will neither be automatically excluded from the EU nor will it automatically become a new Member State. Drawing on the ideas of Articles 49 and 50 TEU this essay develops a procedure for balancing the interests of the EU, its Member States, and the people living in the seceding State, who are likely to be pro-EU. If a Member State breaks up, both the remaining State and the new entity will continue to represent the former Member State in the European institutions. The former Member State will provisionally continue to exist for both the EU and its Member States with respect to European matters. A process of negotiation between the two “new” States themselves and with the other Member States will lead to a new balance within the EU and the adaption of the Treaties – the solution has to be a political one. If the negotiations are successful, the former Member State can finally be dissolved at the EU level. In this case either both new States will become new Members or the remaining State will continue the membership (with

    In a representative UK study (N = 1000) the link between distributive fairness perceptions, outcome favorability, identity, and tax compliance was researched in the context of European transfer payments. Results showed that both forms of tax compliance (i.e., individual and collective EU-tax compliance) were influenced by perceived distributive fairness judgments of EU transfer payments. Fairness itself was related to perceived outcome favorability (i.e., whether their own nation benefits from the EU in financial as well as socio-political terms). Additionally, national identifiers (i.e., people identifying with their own nation, but not with Europe) perceived EU membership as unbeneficial in financial as well as in socio-political terms and thus considered the transfer payments as less fair. Dual identifiers (i.e., people identifying with their own nation and with Europe) perceived the socio-political outcomes from EU membership as more beneficial and thus evaluated the transfer payments as fairer.

  14. Do supranational EU institutions make a difference? EU asylum law before and after ‘communitarization’

    ABSTRACT This article examines whether the empowerment of the European Union's (EU) supranational institutions has had an impact on the development of EU asylum. By systematically investigating EU asylum law before and after ‘communitarization’, it argues that its ‘policy core’ has maintained a high degree of continuity. An advocacy coalition under the leadership of the interior ministers managed to co-opt pivotal actors in the newly empowered European Commission and European Parliament. By contenting themselves with changes of secondary order, these EU institutions accepted and institutionalized the restrictive and weakly integrated core of EU asylum set by the Council in the first negotiation round. Their role and decisions were driven not only by the negotiation dynamics and political expediency, but also by new inter- and intra-institutional norms fostering consensual practices. PMID:26924934

Therefore, the aim of this research is to identify how EU states contribute to helping poor countries, members of the World Trade Organization. For the beginning, we define the EU’position before, during and after the Doha Round – a round of WTO multilateral trade negotiations. Moreover, we analyse the development dimension, focusing on countries „marginalized” until early of XXI century in terms of international trade, because this represents the idea-axis of the Doha Round. In this context, the EU – one of the leading global commercial players and a key member of the institution mentioned above – has set several objectives to achieve the basic goal of negotiations and several ways to support developing countries. To conclude, we propose to define the key points of the European aid for least developed and developing countries.

    The preferred embodiments are directed to a high-energy detector that is electrically shielded using an anode, a cathode, and a conducting shield to substantially reduce or eliminate electrically unshielded area. The anode and the cathode are disposed at opposite ends of the detector and the conducting shield substantially surrounds at least a portion of the longitudinal surface of the detector. The conducting shield extends longitudinally to the anode end of the detector and substantially surrounds at least a portion of the detector. Signals read from one or more of the anode, cathode, and conducting shield can be used to determine the number of electrons that are liberated as a result of high-energy particles impinge on the detector. A correction technique can be implemented to correct for liberated electron that become trapped to improve the energy resolution of the high-energy detectors disclosed herein.

  9. The Impact of the Explosion of EU News on Voter Choice in the 2014 EU Elections

    2016-02-01

    Full Text Available The European elections in 2014 were the first to be held after a long period in which EU-related news was prominent in the media. They were held after years of daily news about the euro crisis and after months of news about the popular uprising in the Ukraine against president Yanukovych, who had refused to sign the association agreement with the EU. This could have invited political parties to overcome the usual problem of low salience of EU issues by strongly profiling themselves on EU issues. Turnout at the 2014 EU elections, however, remained low, hinting that parties were unable to convert the attention for European issues into enthusiasm for their party at the European elections. This paper asks how vote choice was influenced by party campaigning on EU related issues. A news effects analysis based on a content analysis of Dutch newspapers and television, and on a panel survey among Dutch voters revealed that EU issues functioned as wedge issues: the more strongly parties were associated in the news with the euro crisis and the Ukraine, the less they succeeded in mobilizing voters.

    International Nuclear Information System (INIS)

    We have studied the effect of segmentation on the full energy energy deposition of a gamma-ray through the studies on fold distribution. The response of seven segmented TIGRESS detectors up to an energy of 8 MeV has been studied by utilizing standard sources of 152Eu, 56,60Co and a radioactive 11Be beam with an energy of 16.5 MeV. Experiment was performed at the ISAC-II facility at TRIUMF, using a thick gold target. The β¯ decay of 11Be (τ1/2 = 13.81(8) sec) produces high energy gamma-rays up to 7974 keV. A 1 mm thick annular double-sided silicon detector of the BAMBINO detector, was mounted 19.4 mm downstream of the target position and used for detection of the electrons in coincidence with the gamma-rays from the seven TIGRESS detectors. The master trigger allowed data to be collected either in Ge singles mode or with a Ge-Si coincidence condition. Standard sources of 152Eu and 56,60Co were also used to obtain low energy data

    2013-03-01

    An increasing number of area detectors, in use at Diamond Light Source, produce high rates of data. In order to capture, store and process this data High Performance Computing (HPC) systems have been implemented. This paper will present the architecture and usage for handling high rate data: detector data capture, large volume storage and parallel processing. The EPICS area Detector frame work has been adopted to abstract the detectors for common tasks including live processing, file format and storage. The chosen data format is HDF5 which provides multidimensional data storage and NeXuS compatibility. The storage system and related computing infrastructure include: a centralised Lustre based parallel file system, a dedicated network and a HPC cluster. A well defined roadmap is in place for the evolution of this to meet demand as the requirements and technology advances. For processing the science data the HPC cluster allow efficient parallel computing, on a mixture of ×86 and GPU processing units. The nature of the Lustre storage system in combination with the parallel HDF5 library allow efficient disk I/O during computation jobs. Software developments, which include utilising optimised parallel file reading for a variety of post processing techniques, are being developed in collaboration as part of the Pan-Data EU Project (www.pan-data.eu). These are particularly applicable to tomographic reconstruction and processing of non crystalline diffraction data.

  3. EuO and Gd-doped EuO thin films. Epitaxial growth and properties

    Energy Technology Data Exchange (ETDEWEB)

    Sutarto, Ronny

    2009-07-06

    Europium oxide (EuO) based materials exhibit a wealth of spectacular phenomena, including half-metallic ferromagnetism, metal-insulator transition, colossal magneto-resistance, large magneto-optical Kerr effect, tunable ferromagnetic ordering temperatures, and large and long-lived photo-induced conductivity. These extraordinary properties make EuO an ideal candidate for implementation in device applications, in particular, for spintronics. Most of the work in the past has been carried out on bulk EuO, but for device applications it is preferred to have the EuO in thin lm form. A urry of studies have therefore emerged in the last decade in order to explore a wide variety of preparation routes and to investigate the properties of the resulting EuO thin films. A recent highlight is the demonstration that doped EuO films can be fabricated on Si and GaN, thereby exhibiting the expected spin-polarized transport effects. Nevertheless, it is still far from a trivial task to prepare EuO thin films with well de ned properties. For bulk EuO, it is already known that stoichiometry is the key issue, and that the presence of small amounts of defects or impurities quickly lead to very large deviations of the material properties. In fact, to make bulk EuO to be stoichiometric one needs temperatures as high as 1800 C. It is obvious that such high temperatures are not compatible with device engineering processes. The preparation of thin films must therefore involve much lower temperatures, preferably not higher than 400-500 C. The consequences are very dear. It turned out that many of the recent studies on EuO thin films are suffering from sample quality problems, due to the presence of, e.g., trivalent Eu species (Eu{sub 3}O{sub 4}, Eu{sub 2}O{sub 3}), oxygen vacancies, or even Eu metal clusters. Controlled doping of the EuO with trivalent rare-earth ions is also not trivial, since most often even the actual doping concentrations were not known. In fact, one could also question in

  4. Radiation damage in barium fluoride detector materials

    Energy Technology Data Exchange (ETDEWEB)

    Levey, P.W.; Kierstead, J.A.; Woody, C.L.

    1988-01-01

    To develop radiation hard detectors, particularly for high energy physics studies, radiation damage is being studied in BaF/sub 2/, both undoped and doped with La, Ce, Nd, Eu, Gd and Tm. Some dopants reduce radiation damage. In La doped BaF/sub 2/ they reduce the unwanted long lifetime luminescence which interferes with the short-lived fluorescence used to detect particles. Radiation induced coloring is being studied with facilities for making optical measurements before, during and after irradiation with /sup 60/C0 gamma rays. Doses of 10/sup 6/ rad, or less, create only ionization induced charge transfer effects since lattice atom displacement damage is negligible at these doses. All crystals studied exhibit color center formation, between approximately 200 and 800 nm, during irradiation and color center decay after irradiation. Thus only measurements made during irradiation show the total absorption present in a radiation field. Both undoped and La doped BaF/sub 2/ develop damage at minimum detectable levels in the UV---which is important for particle detectors. For particle detector applications these studies must be extended to high dose irradiations with particles energetic enough to cause lattice atom displacement damage. In principle, the reduction in damage provided by dopants could apply to other applications requiring radiation damage resistant materials.

    Full Text Available This article provides a critical review of the “terms” of the ongoing EU enlargement, in the light of the European public interest. The European public interest ought to include the prospective (Central European members, within a perspective of an enlarged Union in 2010, or so. The following forms a personalised summary of a major report published (in Dutch in September 2001 by the WRR in The Hague (a think-tank, formally under the Dutch Prime Minister, but by statute fully independent. The author was one of the lead-writers of this report. The present article merely focuses on the policy recommendations of the report. It is hoped that these kinds of critical analyses will help to stimulate solid policy debate on the EU in Romania, on the road to EU membership. The article discusses why the notion of a “core-acquis” would improve the enlargement strategy; the application of the core acquis to the internal market, environment and justice and home affairs; judicial and administrative capacity; accession to “euro-land”; the rapid reform of the CAP; a reform of “cohesion” approaches; and a note on the EU budgetary implications.

    2010-11-01

    In order to allow for the detection of low momentum particles, originating from the scattering of a 27.6 GeV lepton beam off a fixed gaseous target at the HERMES experiment at DESY in Hamburg (Germany), a dedicated recoil detector was installed. It consists of a silicon strip detector, located inside the beam vacuum, a scintillating fiber tracker and a photon detector, around a 150 mm long target cell made out of a 75{mu}m thick aluminum tube. The full detector assembly is mounted inside a 1 T super-conducting solenoid and is able to detect protons and pions with momenta up to 1.40 GeV/c and photons in the region surrounding the target cell. The detector has been operational from February 2006 until June 2007. The commissioning and performance of the detector are presented in this paper.

    This article brings to light several inconsistencies within the narrative of the EU policy on institutional multilingualism. The EU has invoked fundamental EU principles of democracy, equality and transparent government, to publically bolster the need for its institutions to communicate and operate in the languages of its citizens. However, these principles do not allow for the pragmatic and budgetary arguments that the EU uses to justify the in reality limited number of official and de facto...

  14. Optical properties of CdBr2:Eu and CdBr2:Eu, Mn crystals

    International Nuclear Information System (INIS)

    Optical and luminescent properties of the CdBr:Eu and CdBr2:Eu, Mn crystals, grown through the Stockbarger-Bridgman method in evacuated quartz ampoules, are studied within the temperature range of 85-295 K. The results obtained are compared with spectral characteristics of the CdBr2 and CdBr2:Mn crystals. The band with the maximum about 254 nm, observed in the absorption spectra of mono- and polyactivated crystals of cadmium bromide, is attributed to the 4f7 -> 4f65d electron transitions in the Eu2+ ions. The manganese sensitized luminescence is identified by excitation of the CdBr2:Eu, Mn crystals by the light from the area of this band. The nature of the capture centers, responsible for thermostimulated fluorescence, and excitation mechanisms of recombination luminescence in the studied crystals are considered

  17. Modeling indirect detectors for performance optimization of a digital mammographic detector for dual energy applications

    International Nuclear Information System (INIS)

    Dual Energy imaging is a promising method for visualizing masses and microcalcifications in digital mammography. The advent of two X-ray energies (low and high) requires a suitable detector. The scope of this work is to determine optimum detector parameters for dual energy applications. The detector was modeled through the linear cascaded (LCS) theory. It was assumed that a phosphor material was coupled to a CMOS photodetector (indirect detection). The pixel size was 22.5 μm. The phosphor thickness was allowed to vary between 20mg/cm2 and 160mg/cm2 The phosphor materials examined where Gd2O2S:Tb and Gd2O2S:Eu. Two Tungsten (W) anode X-ray spectra at 35 kV (filtered with 100 μm Palladium (Pd)) and 70 kV (filtered with 800 pm Ytterbium (Yb)), corresponding to low and high energy respectively, were considered to be incident on the detector. For each combination the contrast- to-noise ratio (CNR) and the detector optical gain (DOG), showing the sensitivity of the detector, were calculated. The 40 mg/cm2 and 70 mg/cm2 Gd2O2S:Tb exhibited the higher DOG values for the low and high energy correspondingly. Higher CNR between microcalcification and mammary gland exhibited the 70mg/cm2 and the 100mg/cm2 Gd2O2S:Tb for the low and the high energy correspondingly

    The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) at CERN. The experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons. In this paper the performance of the various LHCb sub-detectors and the trigger system are described, using data taken from 2010 to 2012. It is shown that the design criteria of the experiment have been met. The excellent performance of the detector has allowed the LHCb collaboration to publish a wide range of physics results, demonstrating LHCb's unique role, both as a heavy flavour experiment and as a general purpose detector in the forward region.

  6. Detector support head

    International Nuclear Information System (INIS)

    The support head of detectors for densitometric measurements of the regional function of lungs using gamma radiation consists of a group of detectors placed in a common rack. The detectors are placed on holders with adjustable height which allow side movement. The holders are slidably connected to the converging quide rail on the frame via arms. Between the holders and the rack is fitted the drive mechanism consisting of a screw. The design allows the stable adjustment of detectors on the lung field during examination and thereby allows the comparison of results of measurements carried out at different times. (J.B.). 2 figs

  7. alpha/beta radiation detector using wavelength and delayed fluorescence discrimination

    This paper describes a novel two-layer radiation detector for alpha/beta simultaneous counting for dust radiation monitoring in nuclear power plants. For alpha/beta discrimination, wavelength and delayed fluorescence discrimination techniques were newly developed. To establish the wavelength discrimination, we adopted a two-layer scintillator consisting of the plastic scintillator (NE-111A) and Y sub 2 O sub 2 S(Eu) whose emission spectra are quite different. To reject the mixed beta signal in the alpha detection layer, we used the delayed fluorescence characteristics of Y sub 2 O sub 2 S(Eu) in the signal processing. We manufactured the detector and tested its feasibility and the detection performance for dust radiation monitoring. Finally, we concluded that the performance of this new alpha/beta detector using the new discrimination methods is suitable for dust radiation monitoring.

  8. EU Climate Policy Tracker 2011. Main report

    Energy Technology Data Exchange (ETDEWEB)

    Limiting the rise in the average global temperature to 2C has been the EU goal since 1996, and in December 2010 the UN recognised the need to consider a 1.5C limit. Avoiding overshooting these levels will require massive emissions reductions - in the order of 80-95% for industrialised countries, like those in the EU. The next ten years are crucial in establishing whether society will be able to make this transition, or whether temperature increase limits will be irreversibly missed. Last year, the European Union Climate Policy Tracker (EU CPT) investigated each member state's implementation of policy and legislation, and rated their progress towards a 2050 vision of deep decarbonisation using renewable energy. The uniquely developed rating scheme, modelled on appliance efficiency labels (A-G), gave an indication of how member states were doing compared to a 'low-carbon policy package'. The average score was an 'E', indicating that the level of effort needed to treble, to be on a pace to reach the 2050 vision. However, aggregating best practices across sectors and countries doubled the score - meaning that the tools are already at hand for major improvements across Europe. This report builds on last year's EU CPT by giving an update on action in member states, and an indicative trend in the rating, as well as adding a new section on EU policy. The addition of an EU section is appropriate, with the Commission having produced a roadmap on a low-carbon economy by 2050, a transport white paper, and with another roadmap for 2050 focused on energy anticipated by the end of 2011. This report seeks to answer the question of whether these and other related initiatives are sufficient to help Europe reach its low-carbon goals. When interpreting the results of this report, it is important to understand that the goal underlying the vision here is not the same as the one in the European Commission's 'low-carbon economy' roadmap

  9. The EU's cybercrime and cyber-security rulemaking: mapping the internal and external dimensions of EU security

    OpenAIRE

    Fahey, E.

    2014-01-01

    By taking the EU Cyber Strategy as a case in point, this contribution examines how the distinction between external and internal security in contemporary EU law manifests itself in large-scale risk regulation and in particular, how the EU relies upon external norms to regulate risk. This article also maps the evolution of the rule-making processes themselves.

    2015-01-01

    In the recently issued Opinion 2/13, the EU Court of Justice ruled that EU accession to the European Convention on Human Rights on the basis of the current Draft Accession Agreement would be incompatible with the EU Treaties. This article examines the impact of Opinion 2/13 on European fundamental...... rights protection. It argues that the concerns for EU law autonomy expressed in the Opinion for the most part are unwarranted and that the Court, through the use of classic constitutionalist language, seeks to position EU law as the superior European fundamental rights regime. The article furthermore...... and coherence of fundamental rights in Europe....

    A strontium iodide crystal doped by europium (SrI{sub 2}(Eu)) was produced by using the Stockbarger growth technique. The crystal was subjected to a characterization that includes relative photoelectron output and energy resolution for {gamma} quanta. The intrinsic radioactivity of the SrI{sub 2}(Eu) crystal scintillator was tested both by using it as scintillator at sea level and by ultra-low background HPGe {gamma} spectrometry deep underground. The response of the SrI{sub 2}(Eu) detector to {alpha} particles ({alpha}/{beta} ratio and pulse shape) was estimated by analysing the {sup 226}Ra internal trace contamination of the crystal. We have measured: {alpha}/{beta}=0.55 at E{sub {alpha}}=7.7MeV, and no difference in the time decay of the scintillation pulses induced by {alpha} particles and {gamma} quanta. The application of the obtained results in the search for the double electron capture and electron capture with positron emission in {sup 84}Sr has been investigated at a level of sensitivity: T{sub 1/2}{approx}10{sup 15}-10{sup 16}yr. The results of these studies demonstrate the potentiality of this material for a variety of scintillation applications, including low-level counting experiments.

    Atomic distribution in phosphors for neutron detection has not been fully elucidated, although their ionization efficiency is strongly dependent on the state of the rare earth in the matrix. In this work, we examine optical properties of Eu-doped 80LiF-20CaF2 eutectics for neutron detector applications based on the Eu distribution. At low concentrations, aggregation of Eu cations is observed, whereas homogeneous atomic dispersion in the CaF2 layer, to substitute Ca(2+) ions, is observed in the eutectics at high concentrations. Eu LIII edge X-ray absorption fine structure (XAFS) analysis suggests that neutron responses do not depend on the amount of Eu(2+) ions. However, transparency, which depends on an ordered lamellar structure, is found to be important for a high light yield in neutron detection. The results confirm the effectiveness of the basic idea concerning the separation of radiation absorbers and activators in particle radiation scintillation and present potential for further improvement of novel bulk detectors.

    The next big project in high energy physics should be a high energy e /sup +/e/sup -/ linear collider, operating at energies up to around 1 TeV. A vigorous R&D program has started to prepare the grounds for a detector at such a machine. The amounts of precision data expected at this machine make a novel approach to the reconstruction of events necessary; the particle flow ansatz. This in turn influences significantly the design of a detector for such an experiment. Apart from work ongoing for the linear collider detector, preparations are under way for an update of the LHC. This requires extremely radiation hard detectors. In this paper the state of the different detector development projects is reviewed. (21 refs).

    We investigated the effect of Mg codoping on luminescence properties of AlGaN:Eu to improve emission through synergy effect between an increase in bandgap by AlGaN and the Mg codoping technique. The luminescence properties of AlGaN:(Eu, Mg) are strongly influenced by the Mg concentration and Al composition. Mg codoping in AlGaN was observed to contribute to increasing photoluminescence (PL) integrated intensity and to improve thermal quenching from 7.3% to 60% while the dominant optical site remained site B (622.3-nm peak) with low excitation cross section. The total concentration of optically activated Eu at 25 K was a constant at for either optical site, indicating that Mg codoping did not affect the formation of optical sites. The PL decay times at room temperature (RT) increased with Mg concentration because of suppression of the back-transfer process. For optimized Mg concentration, an increase in the Al composition contributed to the total activated Eu concentration and changed the dominant optical site from A (620.3-nm peak) to B. The activation energy E{sub a}, which is the difference in energy between the {sup 5}D{sub 0} energy level and the trap level in the host material, was estimated from temperature dependence of PL decay time. The E{sub a} for site A was larger than that for site B, suggesting that the back-transfer rate for site A was less than that for site B. - Highlights: • Eu and Mg codoped AlGaN was grown on GaN template by NH{sub 3}-MBE. • The effect of Mg codoping on optical properties of Eu doped AlGaN was investigated. • Mg codoping contributed to increase PL intensity at RT and improve thermal quenching. • An increase in the Al content affected total activated N{sub Eu} and dominant optical site.

  9. Consequences of EU air quality directives for spatial development plans in various EU countries

    International Nuclear Information System (INIS)

    Over the past few years, the highest Dutch court of justice has rejected many building plans for new homes, roads and businesses because of reasons related to EU air quality limit values. This has made it clear that detailed impact assessments are necessary to having plans approved for permits, and that failure to achieve limit values can be a reason to reject a plan. An investigation to see whether such issues have also played a role in other EU countries has proven the contrary. Only a few similar court cases have taken place in other countries, while air quality limit values are breached in other EU countries as well. The reason is that the Netherlands has implemented the first EU Daughter Directive in a relatively strict manner in comparison to other countries, in particular: Adopting a strict legal coupling of air quality and spatial planning policies, with many types of plans being subject to an air quality impact assessment; Perceiving limit values as absolute limit values, whereas in many other countries a need to meet a limit value is weighted with other interests in granting permits; Applying limit values to the whole country. Although this application is, in principle, valid for all EU member states, some member states apply limit values only to locations where people can be exposed; Since air quality assessment is detailed in the Netherlands, many locations are appointed where air quality limit values are breached. Clearly, the role of limit values in granting permits for plans differs considerably among the EU countries, while the underlying EU legislation is the same, and while limit values are breached in other countries as well

  10. Rethinking EU Citizenship: Towards the Postmodern Ethics of Citizenship

    2009-11-01

    Full Text Available The concept of EU citizenship reflects EU politics of (fixed identity, which guarantees rights only to the homogenous groups (and individuals as representatives of these groups. Hence, it leaves room for marginalizing, othering, excluding and other forms of discrimination, by creating binary oppositions: we/they, citizen/alien, EU/non-EU and so forth. EU citizenship is based on the modernist ethics of priority of right over the good. It is created to promote European idea, so it has only instrumental value. On the other hand, the politics of affinity leads to the substantive EU citizenship founded on multiple identities. The politics of affinity requires a new ethics which will lead to transformation of the main concepts of EU legal discourse.

    Full Text Available The paper deals with the analysis of informational efficiency of the European emissions trading scheme (EU ETS with the goal of stating whether or not the system has been able to achieve its proclaimed cost-efficiency within the first two trading periods. The efficient market hypothesis suggests that profiting from predicting price behaviour is difficult as the market price should incorporate all available information at any time. I analyse the EU emission market to see if it shows evidence of the weak form of informational efficiency. In order to analyse the weak form of informational efficiency assessments I analyse random walk properties such as, the unit root, autocorrelation and variance ratio tests. The results reveal the existence of informational efficiency only in the second trading period.

  7. EU Cooperation in the Energy Sector

    International Nuclear Information System (INIS)

    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)

  12. EU Film Policy: between Art and Commerce

    Directory of Open Access Journals (Sweden)

    Anna Herold

    2004-12-01

    Full Text Available The establishment of the European internal market has involved the cinematographic sector as a result of its economic nature. However, film, as a cultural medium, does not lend itself easily to the trends towards uniformity, inherent in the process of economic integration. This becomes visible in the relationship between national cinematographic legislation, reflecting cultural values, and the free market philosophy pursued within the European integration process. There seems to be a contradiction between national measures, which seek to correct the workings of the market, and the efforts to establish a European common market for audiovisual goods and services. This situation has been further complicated by the introduction of Article 151 into the EU legal order by the Maastricht Treaty, which recognised protection of cultural values as one of the EU constitutional tasks. However, it happened without calling into question the acquis communautaire on cultural matters. As a result, the audiovisual policy at the EU level is characterised by a contradiction between the economic logic of market integration and the goal of preservation of cultural diversity. The inherent conflict between these two objectives becomes very clear when looking at the development of the European film policy. This policy agenda creates an amalgam of two not easily reconcilable aims: promotion of cultural diversity and establishment of an internal film market. This horizontal tension is exacerbated by the clash between the European competition policy measures affecting the film sector and the national cultural policy considerations, which demonstrates how controversial remains the vertical power sharing within the EU. The aim of this paper is to investigate, on the basis of the European Commission policy documents and practice, these two-level tensions within the framework of the European film policy and draw conclusions for its future sustainability.

  14. EU developments of the ITER ECRH system

    International Nuclear Information System (INIS)

    The EU will be providing the largest contribution to the ITER electron cyclotron (EC) heating and current drive (H and CD) system (20 MW, CW at 170 GHz). The contribution includes one third of the H and CD gyrotrons, their associated power supplies and four upper port launcher antennas. In all areas of participation, the EU EC partnership (coordinated by the European Fusion Development Agreement) aims toward advancing the technology, while staying within a specified cost envelope. This is portrayed in the co-axial gyrotron development that offers the potential to double the output power per source (2.0 MW), increasing the delivered power for a fixed number of auxiliary systems. The EU partnerships also attempt to increase performance for the entire EC system, in particular the launching antennas. The proposed front steering launcher design offers greater control of MHD activity than the previous remote steering design and opens up the possibility of an enhanced performance UL. The EC physics requirements are repartitioned between the upper and equatorial launchers for a synergetic balance, which increases the EC physics capabilities while relaxing some of the engineering requirements

    Full Text Available As the importance of tariffs in international trade has declined with the reduction of tariff rates under the GATT/WTO programs of multilateral trade liberalization, most governments prefer to protect domestic industries from foreign competitors through a variety of non-tariff barriers. Antidumping actions have recently become the world's biggest trade impediment due to their specific features and the antidumping activity of new users. Since China has become the major engine of world trade growth in recent years, it also has become the largest anti-dumping target in the world. However, the present world competition situation implies that world trade liberalization might arouse regional trade friction. The objective of this research is to identify whether China's WTO accession changed China's situation with regard to EU antidumping actions. The research analysis empirically proved that trade liberalization could partly affect the EU's antidumping actions against Chinese exports and the higher degree of industrial concentricity becomes a motive to increase the EU's antidumping activities against China.

  17. Eu(III)-doped aluminium yttrium oxide

    International Nuclear Information System (INIS)

    In this work, we report the synthesis and the photoluminescence features of Eu(III)-doped yttrium-aluminium oxide obtained by non-hydrolytic sol-gel routes. After heating the powders above 600 deg C the XRD patterns show the presence of the Y4Al2O9 (YAM) and Y3Al5O12 (YAG) phases. At 800 and at 1500 deg C the PL spectra display the Eu(III) lines characteristic of the YAM monoclinic phase. The 5D0→7F2 transition is favored relatively to the 5D0→7F1 lines. However, at 1100 deg C the cubic YAG is the preferential phase and the 5D0→7F1 transition dominates the spectrum. The Eu(III) ions lie in a centro symmetrical site. The different solvents used in the sol-gel synthesis also change the relative proportion between these two phases. This is monitored analyzing the modifications in the relative intensity between the 5D0→7F2 and the 5D0→7F1 transitions. (author)

    Full Text Available EU has 27 Member States representing a community and a market of 493million citizens, which creates further economic and social disparities between thestates and their 271 regions. In a region in four, the GDP (gross domestic product percapita is 75% below the average for the EU-27. Based on the concepts of solidarity andcohesion, regional policy of the European Union favors reducing structural disparitiesbetween EU regions, the balanced development of the community and promoting aneffective equality of opportunity between people. Over the past 50 years, Europeancooperation has helped build highways, sewage plants, bridges, laboratories forbiotechnology. She helped to revive urban areas and neglected activities, throughcountless projects in the poorest regions of the Union.. Two key values: solidarity andcohesion, underlying these projects and the regional policy of the European Union. Theeconomic, social and territorial cohesion will always be at the heart of Europe Strategy2020, a key mechanism for achieving the priorities for a smart growth, sustainable andinclusive in the Member States and regions.

  19. Additive Technology for EU Ecolabel Formulations

    Currently, Bio -lubricants are still regarded as niche products. Within the global lubricant market, however, the ar-ea of environmentally acceptable fluids represents one of the fast growing markets with an estimated annual growth of more than 6% per year. This growth is supported by various market drivers such as legal regulations, public subsidies and the im-plementation of national or international labeling schemes.With the implementation of the European Ecolabel for lubricants in 2005, a common standard specifying ecological and performance requirements for Bio - lubricants was defined. Applying for the EU Ecolabel requires a comprehensive assess-ment, not only of the final formulation, but also of the additives used. Additives are required to meet specifications for oxi-dation and thermal stability, as well as to impart metal protection (of both steel and yellow metals), thus improving corro-sion protection and wear performance of the formulation. Therefore, it is challenging in terms of formulation technology to develop the right formulation that meets the technical specifications as well as the stringent requirements of the EU - Ecola-bel.The paper describes how, by using ester base fluids and additives currently available in the market, lubricants can be developed to meet the technical and eco - toxicological requirements of the EU - Ecolabel, approaching the performance lev-els of lubricants formulated with traditional base fluids.

    2004-07-01

    Full Text Available This article deals with one of the most important, but also challenging economic issues nowadays, which is economic competitiveness. The literature is not unanimous in recognizing the importance of competitiveness, especially where it concerns the state level. However, the relevance of international competitiveness is increasingly brought into light by theory, specific policy measures and by periodical evaluations made by international organizations. Against this background, the EU is one of the main players whose position is still lagging behind the USA, and, according to recent evaluations, behind the other OECD countries. The European Council in March 2000, held in Lisbon, had launched a very inciting challenge – that of transforming the EU economy into the most competitive and dynamic knowledge-based economy in the world, by 2010. Such an ambitious target requires an evaluation of the competitiveness level and also new measures to be taken in order to accomplish this objective.The article presents opinions on the EU competitiveness issue, and on the main weak and strong points, concluding that even the target and especially the schedule seem to be unrealistic, the new direction of action, i.e. towards better business conditions for enterprises being correct.

    The fluorescent complex Eu(TTA)2(Phen)(MA) (HTTA=2-Thenoyltdfluoroacetone, Phen=l,10-phenanthroline, MA=Maleic an-hydrider) was synthesized and characterized with elemental analysis, infrared spectrum (IR), scanning electron microscope (SEM), X-ray Diffraction(XRD), differential scanning calorimetry(DSC), and fluorescent measurement. To explore the effect of different physical disper-sion state of Eu-complex on the fluorescent property of the Eu-complex/silicon rubber composites, various quantities of Eu(TTA)2(phen) (MA) were mixed with silicon rubber (SIR) and peroxide to form uncured composites. These composites were vulcanized to obtain cured Eu-complex/SiR composites at 250 ℃, which was higher than the melting-point of Eu-complex. The SEM, XRD, DSC, and the fluorescent measurement of these composites showed that both the complex molecules dispersed in the silicon rubber during the melting process and the parent Eu-complex particles had positive effects on fluorescent property, whereas the re-crystallized Eu-complex particles and the ggregating complexes formed during the melting-process had negative effects on fluorescent property. For the uncured composites, their fluorescent intensities almost did not change with the increasing amount of Eu-complex. Furthermore, for the composites with small content of Eu-complex, their fluorescent intensities decreased significantly after curing, and this difference in fluorescent intensity became smaller as the content of Eu-complex increases.

  2. Distribution of 152Eu and 154Eu in the ‘alluvial soil–rhizosphere–plant roots’ system

    International Nuclear Information System (INIS)

    Accumulation of 152Eu and 154Eu isotopes in bulk soil and rhizosphere soil in the near-field zone of influence of the Krasnoyarsk Mining and Chemical Combine was studied. An uneven distribution of specific activity of Eu isotopes was observed, with the gross specific activities of the isotopes in the bulk soil exceeding those of the rhizosphere. In the most contaminated locations the fine and the coarse granulometric fractions are enriched with the isotopes. A laboratory experiment indicated potential removal of soluble Eu isotopes by river flood waters may amount to 3% of the total Eu in both bulk and rhizosphere soils. The root system of plants growing in the contaminated territory accumulates 152Eu and 154Eu, although the isotopes were not discovered in aboveground parts of plants. Root-hairs were found to be the most contaminated. - Highlights: ► Gross specific activities of Eu isotopes in bulk soil exceed those in the rhizosphere. ► The fine and the coarse granulometric fractions are enriched with Eu isotopes. ► The removal of Eu isotopes by high waters amounts to 3%. ► Only root system of plants accumulates Eu isotopes. ► Root-hairs were found to be the most contaminated.

    . The variation of the excitation wavelength can tune the emission spectra as well as Commission Internationale de L’Eclairage (CIE) chromaticity coordinates of Eu/Tb co-doped glasses for specific applications. The energy transfer from Tb3+ to Eu3+ ions is investigated by analyzing fluorescence spectra and decay...... such as B2O3, Al2O3 and CaF2 on the luminescent properties of the above-mentioned glasses. We explore the role of Eu3+ ions as a structural probe of the glasses by determining the asymmetry factor, i.e., the ratio of the emission intensity of the 5D0→7F2 transition to that of the 5D0 →7F1 transition....... The results show that the asymmetry factor and luminescence lifetimes of as-prepared materials are dependent on composition. White fluorescence is achieved in Eu/Tb co-doped glasses, which can be attributed to the simultaneous generation of red, green and blue wavelengths from Eu3+ and Tb3+ ions...

  4. EU Think Tank Fora as Transaction Cost Reducers: A Study of Informal Interest Intermediation in the EU

    Full Text Available By examining the organisational structure of EU think tank fora (seminars, workshops and conferences, this article proposes that fora can play the role of transaction cost reducers in EU policymaking. I argue that certain aspects of EU policymaking, including i controlled processes of consultation, ii diminishing costs of management, and iii the risk of state capture, incentivise EU institutions to outsource part of the consultation activity to policy actors that can help EU institutions fulfil their informational and legitimacy needs. I argue that think tanks are able to play this role because they i reduce information asymmetries by connecting a wide variety of policy actors and ii act as intermediaries that mitigate opportunistic behaviour. The empirical assessment reveals that the dimensions characterising transactions are present in EU think tank fora. It shows that policy actors that do not usually participate in formal consultation processes frequently attend fora where they meet representatives of EU institutions, particularly Parliament and Commission representatives.

    For the final running period of HERA, a recoil detector was installed at the HERMES experiment to improve measurements of hard exclusive processes in charged-lepton nucleon scattering. Here, deeply virtual Compton scattering is of particular interest as this process provides constraints on generalised parton distributions that give access to the total angular momenta of quarks within the nucleon. The HERMES recoil detector was designed to improve the selection of exclusive events by a direct measurement of the four-momentum of the recoiling particle. It consisted of three components: two layers of double-sided silicon strip sensors inside the HERA beam vacuum, a two-barrel scintillating fibre tracker, and a photon detector. All sub-detectors were located inside a solenoidal magnetic field with an integrated field strength of 1Tm. The recoil detector was installed in late 2005. After the commissioning of all components was finished in September 2006, it operated stably until the end of data taking at HERA end of June 2007. The present paper gives a brief overview of the physics processes of interest and the general detector design. The recoil detector components, their calibration, the momentum reconstruction of charged particles, and the event selection are described in detail. The paper closes with a summary of the performance of the detection system.

    Originally organised as a sub-system in the DAQ/EF-1 Prototype Project, the Detector Interface Group (DIG) was an information exchange channel between the Detector systems and the Data Acquisition to provide critical detector information for prototype design and detector integration. After the reorganisation of the Trigger/DAQ Project and of Technical Coordination, the necessity to provide an adequate context for integration of detectors with the Trigger and DAQ lead to organisation of the DIG as one of the activities of Technical Coordination. Such an organisation emphasises the ATLAS wide coordination of the Trigger and DAQ exploitation aspects, which go beyond the domain of the Trigger/DAQ project itself. As part of Technical Coordination, the DIG provides the natural environment for the common work of Trigger/DAQ and detector experts.

    The development of europium-doped strontium iodide (SrI2(Eu)) has attracted considerable attention, because of its excellent material properties as regards gamma-ray scintillator applications. These include its excellent energy resolution, high light output (> 80 , 000 ph / MeV), and high effective atomic number (Z=49). Here we report on the performance of ϕ 1 in×1 in SrI2(Eu) cylindrical crystals newly fabricated by Union Materials Inc. In this study, we measured the energy resolution and light output at 10 °C temperature intervals between -40 and 40 °C, using an optically coupled 2-in photomultiplier tube (PMT) (Super Bialkali, Hamamatsu). The SrI2(Eu) light output increased by 0.12%/°C as the temperature decreased. At -40 °C, we obtained the optimal energy resolution recording 2.91±0.02% full width at half maximum (FWHM) for 662 keV gamma rays measured with 137Cs. For comparison, we also measured the same crystal using both a large-area (19×19 mm2) avalanche photodiode detector (APD) and 8×8 multi-pixel photon counter (MPPC) arrays of 3×3 mm2 pixels. The energy resolutions of 2.94±0.02%, 3.14±0.06% and 3.99±0.01% were obtained using PMT, APD, and MPPC, respectively, as measured at -20 °C. We also measured the inherent background of SrI2(Eu) in a cave composed of Cu-Pb blocks with their thickness of 5-10 cm confirming that SrI2(Eu) has an extremely low inherent background radiation. In this study, we have shown that SrI2(Eu) is a promising scintillator that can be utilized for radiation measurements incorporating low-energy X-rays to high-energy gamma rays, and can thus be applied in various medical, industrial, and environmental treatment fields in the near future.

    A review of the application of PIN diodes as radiation detectors in particle counting, X- and γ-ray spectroscopy, medical applications and charged particle spectroscopy is presented. As a practical example of its usefulness, a PIN diode and a low noise preamplifier are included in a nuclear spectroscopy chain for X-ray measurements. This is a laboratory session designed to review the main concepts needed to set up the detector-preamplifier array and to make measurements of X-ray energy spectra with a room temperature PIN diode. The results obtained are compared with those obtained with a high resolution cooled Si-Li detector.

    A new experimental device, the Silicon Cube detector, consisting of six double-sided silicon strip detectors placed in a compact geometry was developed at CENBG. Having a very good angular coverage and high granularity, it allows simultaneous measurements of energy and angular distributions of charged particles emitted from unbound nuclear states. In addition, large-volume Germanium detectors can be placed close to the collection point of the radioactive species to be studied. The setup is ideally suited for isotope separation on-line (ISOL)-type experiments to study multi-particle emitters and was tested during an experiment at the low-energy beam line of SPIRAL at GANIL.

  12. Microfluidic Scintillation Detectors

    CERN Multimedia

    Microfluidic scintillation detectors are devices of recent introduction for the detection of high energy particles, developed within the EP-DT group at CERN. Most of the interest for such technology comes from the use of liquid scintillators, which entails the possibility of changing the active material in the detector, leading to an increased radiation resistance. This feature, together with the high spatial resolution and low thickness deriving from the microfabrication techniques used to manufacture such devices, is desirable not only in instrumentation for high energy physics experiments but also in medical detectors such as beam monitors for hadron therapy.

    Room temperature operating solid state hand held neutron detectors integrate one or more relatively thin layers of a high neutron interaction cross-section element or materials with semiconductor detectors. The high neutron interaction cross-section element (e.g., Gd, B or Li) or materials comprising at least one high neutron interaction cross-section element can be in the form of unstructured layers or micro- or nano-structured arrays. Such architecture provides high efficiency neutron detector devices by capturing substantially more carriers produced from high energy .alpha.-particles or .gamma.-photons generated by neutron interaction.

    Most of the important physics processes to be studied in the international linear collider (ILC) experiment have multi-jets in the final state. In order to achieve better jet energy resolution, the so-called particle flow algorithm (PFA) will be employed and there is a general consensus that PFA derives overall ILC detector design. Four detector concepts for the ILC experiment have been proposed so far in the world; the GLD detector that has a large inner calorimeter radius, which is considered to have an advantage for a PFA, is one of them. In this paper, general scheme and performance of the GLD-PFA will be presented.

    The ATLAS experiment is a multi-purpose particle detector that will study high-energy particle collisions produced by the Large Hadron Collider at CERN. In order to achieve its physics goals, the ATLAS tracking requires that the positions of the silicon detector elements have to be known to a precision better than 10 μm. Several track-based alignment algorithms have been developed for the Inner Detector. An extensive validation has been performed with simulated events and real data coming from the ATLAS. Results from such validation are reported in this paper.

  16. Business interest of Gazprom in the EU-27 in 2007

    International Nuclear Information System (INIS)

    Gazprom is an important supplier of gas to the EU. Liberalisation of the EU gas market has also influenced the gas relations with Russia and the way the Russian Gas company Gazprom is securing its interest in this internal EU market. From a relationship of bilateral gas contracts with EU member states and their companies before gas market liberalisation, a new approach to secure its market share is beginning to evolve. The positioning of Gazprom in the EU market has raised concerns of EU policy makers. There is some trepidation that the investment strategy of Gazprom in the EU gas market will lead to a position of market dominance in an increasingly import dependent EU market. The discussion on Gazprom's market strategy needs to be fed with factual information on its activities and it is exactly what this new report is providing because information on the activities of Gazprom in the various member states' gas sector was incomplete. In this factual report in Dutch, the author presents a comprehensive oversight and characterisation of Gazprom's downstream assets in the EU-27. Through four layers - long-term contracts, company stakes, asset swaps and political support - a detailed insight is given in Gazprom's downstream activities in the EU-27.

    2015-10-01

    Full Text Available Conditionality is mostly defined as the EU policy engendered for candidate countries. However, the mere use of conditionality by the EU does not essentially explain transferring of policies and EU rules towards the candidate countries. EU conditionality may be considered as a comprising approach but in certain policy areas or countries it might not be as successful as it was on other ones. The EU conditionality basically defined as a bargaining policy of affecting through reward, under which the EU provides inducements to candidate or neighbor countries to aligning with the conditions of the EU. In this study the explanatory power of conditionality would be questioned; so the main question will be “to what extent does the EU have influence on policy convergence in a candidate country that does not have a clear membership perspective? Taxation chapter in accession negotiations between Turkey and the EU has been chosen as the case of this research as providing to have an answer on this question. The main objective of this paper is ‘analyzing the extent of EU conditionality on Turkish taxation policy.’ Furthermore, it is argued in this study that “without a concrete incentive, European Union’s impact on a candidate country would be limited.”

    Effective photoswitchable europium sulfide nanocrystals with gold nanoparticles using dithiol (DDT: 1,10-decanedithiol) joint molecules, EuS-Au nanosystems, are demonstrated. The TEM image indicates the formation of EuS-Au nanosystems composed of cube-shaped EuS nanocrystals and spherical Au nanoparticles. Under visible-light irradiation, a drastic change of absorption band of EuS-Au nanosystems at around 600 nm was observed. The Faraday effects of EuS-Au nanosystems were estimated using magnetic circular dichroism (MCD) measurements. The effective change of the MCD spectra of EuS-Au nanosystems under visible-light irradiation was successfully observed at around 670 nm for the first time. The effective reversible changes in MCD spectra with the alternative irradiation cycles of visible light (>440 nm) and dark are also presented. The decrease rate of rotation angle at 670 nm of EuS-Au nanosystems is larger than that of absorbance. These results indicate that the effective change of MCD spectra of EuS-Au nanosystems would be dominated not only by a drastic change of absorption band related to enhanced LSPR of Au nanoparticles but also by specific interaction between EuS and Au in nanosystem under irradiation.

  19. Should the EU climate policy framework be reformed?

    Directory of Open Access Journals (Sweden)

    David ELLISON

    2011-12-01

    Full Text Available Though to-date the European Union (EU has played the most significant leadership role in international negotiations to reduce greenhouse gas (GHG emissions, the emission-reducing performance of individual EU Member states has for many been less than stellar. Several EU15 Member states continue to raise rather than lower emissions. Analysing the most successful policy instruments, this paper argues EU policy efforts could benefit from three important innovations. The following strategies – the adoption of an EU-wide FIT (feed-in tariff, an EU-wide carbon tax and more flexibility in the trading of carbon credits – could significantly improve emission reductions, their relative cost-efficiency and spread burden-sharing more evenly across technologies and Member states. This raises important questions, both about the effectiveness of EU and Kyoto-style commitments, as well as the EU Emission Trading Scheme (ETS. The commitment strategy, and in particular the EU ETS mechanism, have had the smallest impact on emission reductions. The proposed set of strategies could make a far greater contribution to future EU efforts and potentially lock in the impressive progress already made. Such a policy shift, if successful, would also greatly enhance the EU’s already significant credibility and bargaining power in international climate negotiations.

  20. EU import restrictions on genetically modified feeds: impacts on Spanish, EU and global livestock sectors

    Philippidis, G.

    2010-07-01

    Over the last decade, much controversy has surrounded the usage of genetically modified organism (GMO) technology in commercial agriculture. More specifically, it is feared that GMOs may introduce new allergens into the food chain or contribute to antibiotic resistance. At the current time, the European Union (EU) adopts a zero tolerance policy toward non-approved GMO imports, whilst the approval process has not kept pace with the proliferation of new GMO varieties. In the EU livestock sectors, this apparent mis-match threatens to interrupt supplies of high protein feed inputs (e.g., soy meal) from countries with more relaxed regulations regarding GMOs. Employing a well known multi-region computable general equilibrium framework, this study quantitatively assesses the impact of a hypothetical EU import ban on unapproved GMO varieties of soybean and maize imports on livestock, meat and dairy sectors. The model code is heavily modified to improve the characterisation of the agricultural sectors and land usage, whilst a realistic baseline is employed to update the global database to 2008, the year the hypothetical ban is implemented. In the worst case scenario, there are significant competitive losses in EU livestock, meat and dairy sectors. In Spain, the negative impacts are particularly pronounced given the importance of pig production in agriculture. In contrast, all non-EU regions trade balances improve, with notable trade gains in the USA and Brazil. To conclude, the EU must urgently find a long term strategy for GMOs if it is to reconcile political expediency with pragmatic economic concerns. (Author) 21 refs.

    This study described the performance of an array of high-purity Germanium detectors, designed with two different end cap materials-steel and carbon fibre. The advantages and disadvantages of using this detector type in the estimation of the minimum detectable activity (MDA) for different energy peaks of isotope (152)Eu were illustrated. A Monte Carlo model was developed to study the detection efficiency for the detector array. A voxelised Lawrence Livermore torso phantom, equipped with lung, chest plates and overlay plates, was used to mimic a typical lung counting protocol with the array of detectors. The lung of the phantom simulated the volumetric source organ. A significantly low MDA was estimated for energy peaks at 40 keV and at a chest wall thickness of 6.64 cm.

  5. The CLIC Detector Concept

    CERN Document Server

    Pitters, Florian Michael

    2016-01-01

    CLIC is a concept for a future linear collider that would provide e+e- collisions at up to 3 TeV. The physics aims require a detector system with excellent jet energy and track momentum resolution, highly efficient flavour-tagging and lepton identification capabilities, full geometrical coverage extending to low polar angles and timing information in the order of nanoseconds to reject beam-induced background. To deal with those requirements, an extensive R&D programme is in place to overcome current technological limits. The CLIC detector concept includes a low-mass all-silicon vertex and tracking detector system and fine-grained calorimeters designed for particle flow analysis techniques, surrounded by a 4 T solenoid magnet. An overview of the requirements and design optimisations for the CLIC detector concept is presented.

  6. Multiple detectors "Influence Method".

    2016-05-01

    The "Influence Method" is conceived for the absolute determination of a nuclear particle flux in the absence of known detector efficiency and without the need to register coincidences of any kind. This method exploits the influence of the presence of one detector in the count rate of another detector, when they are placed one behind the other and define statistical estimators for the absolute number of incident particles and for the efficiency (Rios and Mayer, 2015a). Its detailed mathematical description was recently published (Rios and Mayer, 2015b) and its practical implementation in the measurement of a moderated neutron flux arising from an isotopic neutron source was exemplified in (Rios and Mayer, 2016). With the objective of further reducing the measurement uncertainties, in this article we extend the method for the case of multiple detectors placed one behind the other. The new estimators for the number of particles and the detection efficiency are herein derived. PMID:26943904

    After decades of development, the Advanced LIGO gravitational wave detectors are now operating, and they completed their first observational run in early 2016. Advanced LIGO consists of two 4-km scale interferometric detectors located at separate sites in the US. The first year of detector commissioning that led to the first observation run produced instruments that have several times better sensitivity to gravitational-wave strain than previous instruments. At their final design sensitivity, the detectors will be another factor of 2-3x more sensitive than current performance. This talk will cover the design of Advanced LIGO, explain how the sensitivity improvements have been achieved, and lay out the path to reaching final design sensitivity.

    International Nuclear Information System (INIS)

    A detector testing device is described which provides consistent, cost-effective, repeatable results. The testing device is primarily constructed of PVC plastic and other non-metallic materials. Sensitivity of a walk-through detector system can be checked by: (1) providing a standard test object simulating the mass, size and material content of a weapon or other contraband, (2) suspending the test object in successive positions, such as head, waist and ankle levels, simulating where the contraband might be concealed on a person walking through the detector system; and (3) swinging the suspended object through each of the positions, while operating the detector system and observing its response. The test object is retained in a holder in which the orientation of the test device or target can be readily changed, to properly complete the testing requirements. 5 figs

    The ATLAS Inner Detector consists of three layers of silicon pixels, four double layers of silicon microstrips and a Transition Radiation Tracker (straw tubes). The good performance of the track and vertex reconstruction algorithms is a direct consequence of the small radius (4.3, 10.1 and 13.2 cm), fine pitch ($50 \\times 300~\\mu$m) and low occupancy ($<3 \\times 10^{-4}$ at design luminosity) of the pixel detectors, and of the good tracking capabilities of the SCT and the TRT. The full detector simulation is used to evaluate the performance of the detector and of the reconstruction algorithms. Results are presented on track and vertex reconstruction efficiencies and resolutions, and on the separation between $b$-jets and jets produced by light quarks.

    A high sensitivity, CO{sub 2} lidar detector, based on recent advances in ultra-low noise, readout integrated circuits (ROIC), is being developed. This detector will combine a high speed, low noise focal plane array (FPA) with a dispersive grating spectrometer. The spectrometer will filter the large background flux, thereby reducing the limiting background photon shot noise. In order to achieve the desired low noise levels, the HgCdTe FPA will be cooled to {approximately}50K. High speed, short pulse operation of the lidar system should enable the detector to operate with the order of a few noise electrons in the combined detector/ ROIC output. Current receiver design concepts will be presented, along with their expected noise performance.

    A modular optical detector system. The detector system is designed to detect the presence of molecules or molecular species by inducing fluorescence with exciting radiation and detecting the emitted fluorescence. Because the system is capable of accurately detecting and measuring picomolar concentrations it is ideally suited for use with microchemical analysis systems generally and capillary chromatographic systems in particular. By employing a modular design, the detector system provides both the ability to replace various elements of the detector system without requiring extensive realignment or recalibration of the components as well as minimal user interaction with the system. In addition, the modular concept provides for the use and addition of a wide variety of components, including optical elements (lenses and filters), light sources, and detection means, to fit particular needs.

    CERN Document Server

    D'Ambrosio, C

    2003-01-01

    Hybrid photon detectors detect light via vacuum photocathodes and accelerate the emitted photoelectrons by an electric field towards inversely polarized silicon anodes, where they are absorbed, thus producing electron-hole pairs. These, in turn, are collected and generate electronic signals on their ohmic contacts. This review first describes the characteristic properties of the main components of hybrid photon detectors: light entrance windows, photocathodes, and silicon anodes. Then, essential relations describing the trajectories of photoelectrons in electric and magnetic fields and their backscattering from the silicon anodes are derived. Depending on their anode configurations, three families of hybrid photon detectors are presented: hybrid photomultiplier tubes with single anodes for photon counting with high sensitivity and for gamma spectroscopy; multi-anode photon detector tubes with anodes subdivided into square or hexagonal pads for position-sensitive photon detection; imaging silicon pixel array t...

    Thermally stimulated luminescence (TSL) investigations of SrBPO5:Eu3+ and SrBPO5:Eu2+ phosphors were carried out in the temperature range of 300–650 K. In order to characterize the phosphors, X-ray diffraction and photoluminescence (PL) techniques were used. The emission spectrum of air heated SrBPO5:Eu3+ phosphor exhibited emission bands at 590, 614, 651 and 702 nm under 248 nm excitation, assigned to transitions of Eu3+ ion. In phosphor prepared in reducing (Ar + 8% H2) atmosphere, a broad emission band due to Eu2+ ranging from 350 to 400 nm was observed with 340 nm excitation. EPR studies have confirmed the presence of Eu2+ ions in the samples prepared in reducing atmosphere. TSL glow curve of SrBPO5:Eu3+ had shown intense peaks around 397, 510, 547 K and a weak peak around 440 K whereas in case of SrBPO5:Eu2+ system, glow peaks at 414, 478 and weak peak at 516 nm were observed. The shift in TSL glow pattern can be attributed to stabilization of different oxidation states of the dopant ion in the host lattice. Apart from this, TSL trap parameters such as trap depth and frequency factor were determined. Spectral characteristics of TSL emission have shown that Eu3+/Eu2+ ion acts as the luminescent centre in the respective phosphors.

    Eu-doped ZnS quantum dots (QDs) have been synthesized by wet-chemical method and found to form in zinc blende (cubic) structure. Both Eu2+ and Eu3+ doped ZnS can be controllably synthesized. The Eu2+ doped ZnS QDs show broad photoluminescence emission peak around 512 nm, which is from the Eu2+ intra-ion transition of 4f6d1 - 4f7, while the Eu3+ doped samples exhibit narrow emission lines characteristic of transitions between the 4f levels. The investigation of the magnetic properties shows that the Eu3+ doped samples exhibit signs of ferromagnetism, on the other hand, Eu2+ doped samples are paramagnetic of Curie-Weiss type. The incident photon to electron conversion efficiency is increased with the Eu doping, which suggests the QD solar cell efficiency can be enhanced by Eu doping due to widened absorption windows. This is an attractive approach to utilize benign and environmentally friendly wide band gap ZnS QDs in solar cell technology.

    expected after 200 ps in most cases. The effect of reducing the charge carrier lifetime and examining the charge collection efficiency has been utilised to explore how these detectors would respond in a harsh radiation environment. It is predicted that over critical carrier lifetimes (10 ps to 0.1 ns) an improvement of 40 % over conventional detectors can be expected. This also has positive implications for fabricating detectors, in this geometry, from materials which might otherwise be considered substandard. An analysis of charge transport in CdZnTe pixel detectors has been performed. The analysis starts with simulation studies into the formation of contacts and their influence on the internal electric field of planar detectors. The models include a number of well known defect states and these are balanced to give an agreement with a typical experimental I-V curve. The charge transport study extends to the development of a method for studying the effect of charge sharing in highly pixellated detectors. The ...

We suggest that the EU has a rational economic interest in forcing the technological development of renewable energy sources to get a first-mover advantage, which will only pay if a sufficient number of countries implement sufficiently stringent GHG reductions. The Kyoto Protocol, which imposes...... binding reductions on 38 OECD countries, implies that, as a first-mover, the EU will be to sell the necessary new renewable technologies, most prominently wind mills, to other countries, when they ratify and implement the Kyoto target levels. In the latest EU proposal made in Johannesburg, the EU pushed...... for setting a target of 15% of all energy to come from sources such as windmills, solar panels and waves by 2015.

    We present magnetocaloric effect measurements of the ferromagnetic semiconductor EuS in the vicinity of its ordering temperature. Single phase EuS powder was synthesized by CS2 gas sulfurization of Eu2O3. A sintered compact with relative density over 95% was prepared by pulsed electric current sintering of the powder. Temperature and magnetic field dependence of the magnetization and specific heat were characteristic of a paramagnetic to ferromagnetic second order phase transition. The entropy change induced by an external magnetic field and the specific heat were both close to those of a single crystal. We obtained an entropy-temperature (S-T) diagram of the EuS sintered compact. Carnot cycle liquefaction of hydrogen using EuS was compared with several other materials, with results indicating that sintered EuS is an excellent magnetic refrigerant for hydrogen liquefaction.

  4. An Update on the Consequences of EU Sugar Reform

    Directory of Open Access Journals (Sweden)

    2011-10-01

    Full Text Available Since its formation the European Union (EU has employed a rather complicated policy to ensure high prices to domestic sugar growers and trade preferences to certain sugar exporting countries, e.g. the African Caribbean and Pacific (ACP group. One result of this policy is that the EU has been both the second largest importer and second largest exporter in the world market. Under pressure from the World Trade Organization (WTO, the EU agreed to reform its policies toward sugar in 2001, with the full effect of the reforms being fully implemented in 2006. In this paper, the impact of the sugar reform on EU production, consumption, imports, and exports is examined especially with regard to how it all affects the ACP countries who receive preferential treatment regarding access to EU sugar markets. Preliminary analysis indicates that lowering domestic EU prices, while quotas requirements for ACP countries remain intact might have negative revenue implications for poor sugar producers.

    Full Text Available Although it has become a common place to blame austerity policies for lengthening the economic downturn of EU economies, the figures reveal that public spending increased in most of the EU countries between 2007 and 2013. Although budget deficits from EU countries were indeed reduced in the last 4 years, the cutbacks were more the result of increasing government revenues and hiking taxes than of decreasing public expenditures. The article will feature: (1 a brief analysis of the evolution of public spending compared to government revenues in EU countries and also, (2 a concise literature review on austerity, highlighting some of the most important theoretical controversies on this topic. The main thesis defended in the article is that – although EU type of austerity, narrowly focusing on fiscal consolidation, drove indeed to unfavorable economic consequences – the criticism formulated by pro stimulus economists is rather flimsy, given the fact that public expenditures actually increased in most of the EU countries.

    This report was commissioned by the Energy Market section of the Dutch Ministry of Economic Affairs (Ministerie van Economische Zaken). The study comprises three tasks: (1) An assessment of the economic reasoning behind the current concentration mechanisms in European electricity markets; (2) A multiple scenario analysis which may help to predict the possible development of market structure in the future, and a comparison of the original EU liberalisation goals with the various scenario outcomes; and (3) An assessment of the effectiveness of current regulatory regimes, with a special focus on competition law, given any revealed mismatch between the original goals of the liberalisation process and the various scenario outcomes. The scope of this assignment is clarified as covering three major aspects of competition policy and its application to the EU electricity sector: EU jurisdiction versus national (Member State) jurisdiction; National government interests versus national competition policy; and The application of standard competition policy guidelines to the specific conditions of electricity markets. In accordance with the terms of reference, this report begins by setting out the goals of liberalisation (chapter 2). In chapters 3 to 6, we consider the motives that drive mergers, we define certain market scenarios and we analyse the observed trends for consolidation in the European electricity industry. Chapter 7 summarises the future trends that we expect to see driving the structure of the electricity industry (in the absence of direct government intervention). In chapters 8 and 9, we analyse European competition law and sector-specific legislation that provides the means to influence the future structure of the electricity industry. Chapter 10 then considers the powers in this legislation, to see whether the future trends in industry structure will conflict with the goals of liberalisation. We identify a number of conflicts. Chapter 11 therefore sets out the

Allerdings helfen sie nicht durch Zuschüsse, sondern durch die Vergabe von Krediten und Garantien. Ognian Hishow bezweifelt, dass die betroffenen Länder - vor allem Griechenland und Portugal - die damit verbundene neuerliche Belastung tragen können. Daher plädiert er dafür, dass die übrigen Euroländer einen Teil der Last übernehmen.

    Eu{sub 2}SiN{sub 3}, a mixed valence europium nitridosilicate, has been prepared via solid-state reaction synthesis and its oxidation behavior and optical properties have been determined. Furthermore, the stability of several isostructural compounds of the type M{sup 2+}L{sup 3+}SiN{sub 3} has been predicted by using the density functional theory calculations, and verified by the actual synthesis of CaLaSiN{sub 3}, CaEuSiN{sub 3} and EuLaSiN{sub 3}. The band gap of CaLaSiN{sub 3} was found around 3.2 eV giving the material its yellow color. Eu{sub 2}SiN{sub 3} on the other hand is black due to a combination of the 4f–5d absorption band of Eu{sup 2+} and the charge transfer band of Eu{sup 3+}. Thermogravimetric analysis and Raman spectroscopic study of Eu{sub 2}SiN{sub 3} revealed that oxidation of this compound in dry air takes place via a nitrogen retention complex. - Graphical abstract: Energy level scheme of Eu{sub 2}SiN{sub 3} showing the occupied N{sup 3−} 2p band (blue rectangle), unoccupied Eu{sup 2+} 5d band (white rectangle), occupied Eu{sup 2+} 4f ground states (filled red circles) and unoccupied Eu{sup 2+} ground states (open red circles). - Highlights: • Density functional theory calculations on the stability of M{sup 2+}L{sup 3+}SiN{sub 3} compounds. • Solid-state reaction synthesis of Eu{sub 2}SiN{sub 3}, CaLaSiN{sub 3}, EuLaSiN{sub 3} and CaEuSiN{sub 3}. • Determination of the Eu{sup 2+} 4f–5d and Eu{sup 3+} CT transitions in M{sup 2+}L{sup 3+}SiN{sub 3} compounds. • Oxidation of Eu{sub 2}SiN{sub 3} in dry air takes place via a nitrogen retention complex.

    At Lisbon in 2000, the European Union (EU) set itself a new strategic goal, namely to become the world's leading economy and to enhance social cohesion across the union, all within a decade. It is argued in this article that one fundamental barrier to the fulfilment of this dream is the fact...... EU budget. Here, the two main redistribution policies, (1) Common Agricultural Policy (CAP) and (2) the Structural Funds, consume more than four fifths of the total annual EU budget. Thus, if the EU is to achieve its strategic goal, a strong cure is needed to reduce redistribution and encourage more...

  6. Limiting emissions trading. The EU proposal on supplementarity

    Energy Technology Data Exchange (ETDEWEB)

    Woerdman, E.

    2001-06-01

    The issue of supplementarity is one of the main reasons for the failure of the sixth Conference of Parties (CoP6). This research memorandum contains both theoretical and empirical analyses to answer the question why the European Union (EU) has proposed to elaborate supplementarity by limiting the use of the Kyoto Mechanisms. Sixteen hypotheses have been formulated and tested by analyzing (a) the content of twelve EU documents, (b) the opinions of fifteen key EU civil servants (who prepare decision-making), including an official from the European Commission, and (c) the behaviour of the EU at CoP6. Firstly, the most surprising result of this study is that the EU environmental bureaucracy is internally divided on the supplementarity issue, because 40% of the approached key officials from different Member States declares - in a personal capacity - to disagree with the official EU proposal to restrict trade by means of a quantitative ceiling (as decided upon by the Ministers). Secondly, the EU documents principally mention hot air to explain the EU position on supplementarity, whereas Peter Vis reflecting the views of the European Commission sees compliance (with a view to strengthening the targets of a second commitment period) as the major reason to restrict emissions trading. Remarkably, the vast majority of the interviewed EU officials do not so much refer to hot air or compliance, but rather to equity as the primary motivation behind the EU proposal to prevent that industrialized countries 'buy their way out'. These and other differences found in the empirical analysis are not only signs of the absence of a coherently composed EU view on the social, economic and environmental effects of a trade restriction, but they are also indications of the presence of internal political divisions within the EU on the issue of emissions trading. This does not strengthen the bargaining position of the EU, although the EU Ministers will try to close their ranks (in

    This paper assesses policy options to stimulate the use of carbon capture and storage (CCS) in the EU. It examines the impacts of enabling CCS under the EU emission trading scheme, making CCS mandatory and subsidies to accompany climate mitigation efforts of the EU. The analysis uses a partial equilibrium energy model and external data. The results suggest that enabling CCS as part of the EU CO{sub 2} trading scheme could save 60 billion - with small impacts on employment. The additional costs of making CCS mandatory or using subsidies are not warranted by the additional cost savings and benefits

  10. Optical properties of Eu3+-doped zinc borate glasses

    International Nuclear Information System (INIS)

    Photoluminescence, absorption and optical excitation spectra of undoped and Eu3+-doped binary zinc borate glasses of varied composition prepared by the melt quenching technique in air atmosphere were investigated. From photoluminescence measurements it was found that growing Eu3+ concentration leads to gradual disappearance of the broadband glass emission in the near-UV spectral range, while the red Eu3+ emission at 613 nm shows a considerable increase. This result together with excitation spectra suggests that the Eu3+ ions are excited via energy transfer from the initially excited glassy host. The glass composition strongly affects the position of the excitation maximum in the UV energy range

    At the beginning of his term of office, the new EU Commissioner for Energy, Andris Piebalgs, announced that controlling the demand for energy was a focal area of interest of the EU Commission. Against this backdrop, the initiative taken by the EU was reasonable to establish a new program promoting energy efficiency at all levels of European society. Accordingly, the EU Commission adopted the announced Energy Efficiency Green Paper (Green Paper on Energy Efficiency or Doing More With Less. Document COM (2005) 265, final date: June 10, 2005). In its Federal Council Document 554/05 of July 4, 2005, the German federal government informed the German federal states about the EU initiative on energy efficiency or 'More with Less'. Green papers by the EU prepare initiatives. This one is to spark off a broadbased discussion involving all stakeholders. The process of opinion forming now due to begin is something to be watched with interest. (orig.)

  19. The CLIC Vertex Detector

    Dannheim, D.

    2015-03-01

    The precision physics needs at TeV-scale linear electron-positron colliders (ILC and CLIC) require a vertex-detector system with excellent flavour-tagging capabilities through a measurement of displaced vertices. This is essential, for example, for an explicit measurement of the Higgs decays to pairs of b-quarks, c-quarks and gluons. Efficient identification of top quarks in the decay t → Wb will give access to the ttH-coupling measurement. In addition to those requirements driven by physics arguments, the CLIC bunch structure calls for hit timing at the few-ns level. As a result, the CLIC vertex-detector system needs to have excellent spatial resolution, full geometrical coverage extending to low polar angles, extremely low material budget, low occupancy facilitated by time-tagging, and sufficient heat removal from sensors and readout. These considerations challenge current technological limits. A detector concept based on hybrid pixel-detector technology is under development for the CLIC vertex detector. It comprises fast, low-power and small-pitch readout ASICs implemented in 65 nm CMOS technology (CLICpix) coupled to ultra-thin planar or active HV-CMOS sensors via low-mass interconnects. The power dissipation of the readout chips is reduced by means of power pulsing, allowing for a cooling system based on forced gas flow. This contribution reviews the requirements and design optimisation for the CLIC vertex detector and gives an overview of recent R&D achievements in the domains of sensors, readout and detector integration.

    The dependences of the sensitivities of the LiI(Eu) thermal neutron detector and the DN-A-1 dosimeter on the isotopic source neutron energy are analyzed. It is shown that the results obtained permit to choose the most confident values for sensitivity of the thermal neutron detectors in moderators. The given data are compared with the experimental and calculated data of other authors. A conclusion is made that the DN-A-1 dosimeter in the energy range from several fractions of eV Up to dozens of keV, as calibrated using a Pu+Be-neutron source, is close to an ''ideal'' dosimeter.

  1. Technology Transfer in the EU: Exporting Strategically Important ICT Solutions to Other EU Member States

    2015-10-01

    Full Text Available The fast development of ICTs pose new challenges to the European Union and its Member States. Every EU country has its own policies regarding technology transfer, ownership of state e-services, and the possibilities how the state-owned or licensed e-service could be exported. Taking into account the free movement of goods, the EU has created a platform to cooperate and export IT solutions. However, the lack of preparedness of infrastructures, legislation and stakeholders for cross-border exchanges poses a threat to IT transfer and should be taken into consideration in the EU as well. In the coming decades the number of outsourced ICT solutions, strategically important ICT solutions, public services and critically important information exchange platforms developed on behalf of the states, will grow exponentially. Still, digital development is uneven across the EU, they grow at different speeds and the performance is quite splintered. There are legal provisions which are outdated and therefore impede technological cooperation and export of IT solutions. A Member State may restrict the ICT licensing based on national security and policy reasons and the ownership of intellectual property might pose a threat to technology transfer or further development of the IT solution. There are examples of strategically important export of ICT solutions, the experience at which can be expanded to cover other EU Member States. Strong collaboration would enable mutual learning from past experiences along with the opportunities for better use of technology. Parallels can be drawn with military technology transfers, as the policies and legal framework was first developed and mostly used with them.

    Some Eu-doped scintillators, such as Eu:SrI{sub 2}, emit around 400-nm wavelength that originates from 5d-4f transition of Eu{sup 2+}, while some Eu-doped crystals have emissions from Eu{sup 3+} (f-f emission). In this report, effect of Eu-doping on optical and scintillation properties of SrF{sub 2} crystals with Core-valence luminescence is discussed. The samples had 0.1, 0.2, 0.5, 1.0, and 2.0 mol% of Eu and were grown by an annealing method. As a result, {sup 5}D{sub 0}-{sup 7}F{sub i} (i =1, 2) transition (Eu{sup 3+}) was detected in the SrF{sub 2}, containing over 0.5 mol% of Eu, while emission from 0.1 and 0.2-mol% Eu:SrF{sub 2} originated from 5d-4f transition of Eu{sup 2+} and Core-valence luminescence. The light output of SrF{sub 2} doped with 0.1, 0.2, 0.5, 1.0 and 2.0 mol% Eu was estimated to be 13,000 {+-} 1,000, 12,000 {+-} 1,000, 13,000 {+-} 2,000, 8,000 {+-} 1,000 and 7,000 {+-} 1,000 photons/MeV, respectively.

    Full Text Available An alarming decision “to pause” the process of Ukrainian Eurointegration taken by the previous government of Ukraine, turned out to be highly disturbing, both to the Ukrainian people and the EU in terms of planned partnership. Following the country’s course change a series of dramatic events unraveled triggering a mass protest movement called Euromaidan across major part of Ukraine, indicating the position of Ukrainian society towards the events. The further unfolding of the events in the Ukraine starting from November 22, 2013 diminished the “euro” direction making it solemnly “MAIDAN”. The direction of Eurointegration in Ukraine’s foreign policy was no longer the priority of the rebel movement, shifting the focus of those protesting to the internal issues. During the Maidan the EU’s representatives initiated and participated in the negotiation process between the government and the opposition, thus demonstrating support to Ukraine on its way to democracy. In the meantime, Maidan expected stricter sanctions towards representatives of the state at that time: freezing of the accounts of those associated with corruption as well as their visa bans and restrictions for travel and business conduction in the EU, etc.. The EU’s lasting conservative behavior was regarded negatively by protesters and lead to disappointment.

    2013-01-01

    For the final running period of HERA, a recoil detector was installed at the HERMES experiment to improve measurements of hard exclusive processes in charged-lepton nucleon scattering. Here, deeply virtual Compton scattering is of particular interest as this process provides constraints on generalised parton distributions that give access to the total angular momenta of quarks within the nucleon. The HERMES recoil detector was designed to improve the selection of exclusive events by a direct measurement of the four-momentum of the recoiling particle. It consisted of three components: two layers of double-sided silicon strip sensors inside the HERA beam vacuum, a two-barrel scintillating fibre tracker, and a photon detector. All sub-detectors were located inside a solenoidal magnetic field with an integrated field strength of 1 Tm. The recoil detector was installed in late 2005. After the commissioning of all components was finished in September 2006, it operated stably until the end of data taking at HERA end...

    Nonequilibrium superconducting detectors exploit the early stages of the energy down cascade which occur after the absorption of radiation. They operate on a short temporal scale ranging from few microseconds down to tens of picoseconds. In such a way they provide fast counting capability, high time discrimination and also, for some devices, energy sensitivity. Nonequilibrium superconducting detectors are developed for their use both in basic science and in practical applications for detection of single photons or single ionized macromolecules. In this paper we consider two devices: distributed readout imaging detectors (DROIDs) based on superconducting tunnel junctions (STJs), which are typically used for high-speed energy spectroscopy applications, and hot-electron superconductive detectors (HESDs), which are typically used as fast counters and time discriminators. Implementation of the DROID geometry to use a single superconductor is discussed. Progress in the fabrication technology of NbN nanostructured HESDs is presented. The two detectors share the high sensitivity that makes them able to efficiently detect even single photons down to infrared energy.

    Free Electron Lasers opened a new window on imaging the motion of atoms and molecules. At SLAC, FEL experiments are performed at LCLS using 120Hz pulses with 1012 - 1013 photons in 10 femtoseconds (billions of times brighter than the most powerful synchrotrons). This extreme detection environment raises unique challenges, from obvious to surprising. Radiation damage is a constant threat due to accidental exposure to insufficiently attenuated beam, focused beam and formation of ice crystals reflecting the beam onto the detector. Often high power optical lasers are also used (e.g., 25TW), increasing the risk of damage or impeding data acquisition through electromagnetic pulses (EMP). The sample can contaminate the detector surface or even produce shrapnel damage. Some experiments require ultra high vacuum (UHV) with strict design, surface contamination and cooling requirements - also for detectors. The setup is often changed between or during experiments with short turnaround times, risking mechanical and ESD damage, requiring work planning, training of operators and sometimes continuous participation of the LCLS Detector Group in the experiments. The detectors used most often at LCLS are CSPAD cameras for hard x-rays and pnCCDs for soft x-rays.

  13. The ZEUS microvertex detector

    Garfagnini, A

    1999-01-01

    A new vertex detector for the ZEUS experiment at HERA will be installed during the 1999-2000 shutdown, for the high-luminosity runs of HERA. It will allow to reconstruct secondary vertex tracks, coming from the decay of long-lived particles with a lifetime of about 10 sup - sup 1 sup 2 s, and improve the global momentum resolution of the tracking system. The interaction region will be surrounded with single-sided silicon strip detectors, with capacitive charge division: three double layers in the central region (600 detectors), and 4 'wheels' in the forward region (112 silicon planes). Due to the high number of readout channels, 512 readout strips per silicon plane in the barrel region and 480 in the forward part, and the large coverage of the vertex detector (almost 1 m long), the front-end electronics has to be placed on top of the detectors and has to be radiation tolerant since doses up to 2 kGy are expected near the interaction region. The HELIX chip has been chosen as analog chip with a low-noise, charg...

  14. Eu2+/Eu3+-doped oxyfluoride glass ceramics with LaF3 for white LED color conversion

    2015-03-01

    SiO2-Na2O-Al2O3-LaF3 glasses doped with Eu2+ and Eu3+ were synthesized to realize an inorganic color converter for white LED using 400 nm UV LED. Among various rare earth ions, Eu2+ and Eu3+ showed prominent emission under 400 nm LED excitation. Carbon and EuF3 content were varied to control the ratio of Eu2+ and Eu3+ during the melting process. When the ratio of Eu2+ and Eu3+ within the glass matrix was properly controlled, color coordinates of the photoluminescence spectra could be adjusted to make white colors under 400 nm LED excitation. The emission intensity was increased with subsequent heat treatment which led to the formation of LaF3 nano-crystals. However, almost no conversion was observed when the glasses were actually mounted on UV-LED to make a white LED. Heavy crystallization of the oxyfluoride glasses was thus investigated to improve its scattering of the light source and color conversion efficiency, and its practical feasibility as an inorganic UV-LED color converter was demonstrated.

  15. The Delphi outer detector

    International Nuclear Information System (INIS)

    The design criteria, construction and performance of the Delphi outer detector are discussed. The detector is a 5-layer, 5 m long, 2 m inner radius, 2.1 m outer radius 'cylindrical' drift chamber consisting of 3480 individual 1.65x1.65 cm2 drift tubes operating in limited streamer mode. The drift time-distance relationship for a single tube has been measured using a pulsed laser as a function of both track angle and longitudinal magnetic field. These data have been used to reconstruct cosmic rays in a completed detector module and yield a transverse resolution of 80 μm per point over most of the cell, rising to 90 μm near the corners of the tubes. The detection efficiency per cell for minimum ionising particles is greater than 98.5%. (orig.)

  16. The H1 detector

    International Nuclear Information System (INIS)

    The H1 detector presently operating at the HERA e-p collider is described. A general overview of the detector is given with particular emphasis on the calorimeters, the main element of which is a liquid Argon calorimeter enclosed within a large radius solenoid. Calorimetry in the proton direction, close to the beam-pipe is provided by a copper-silicon pad hadronic calorimeter. In the electron direction a lead-scintillator electromagnetic calorimeter closes the solid angle between the rear part of the liquid Argon calorimeter and the beam-pipe. An iron limited streamer tube tail catcher using the return yoke of the solenoid as absorber completes the calorimetry of the detector. The hardware triggers derived from the calorimeters are also described and some performance details of the calorimeters are given

    The recent advances in Si and diamond detector technology give hope of a simple solution to the radiation hardness problem for vertex trackers at the LHC. In particular, we have recently demonstrated that operating a heavily irradiated Si detector at liquid nitrogen (LN$_2$) temperature results in significant recovery of Charge Collection Efficiency (CCE). Among other potential benefits of operation at cryogenic temperatures are the use of large low-resistivity wafers, simple processing, higher and faster electrical signal because of higher mobility and drift velocity of carriers, and lower noise of the readout circuit. A substantial reduction in sensor cost could result The first goal of the approved extension of the RD39 program is to demonstrate that irradiation at low temperature in situ during operation does not affect the results obtained so far by cooling detectors which were irradiated at room temperature. In particular we shall concentrate on processes and materials that could significantly reduce th...

    2012-01-01

    We review the basic features of transition radiation and how they are used for the design of modern Transition Radiation Detectors (TRD). The discussion will include the various realizations of radiators as well as a discussion of the detection media and aspects of detector construction. With regard to particle identification we assess the different methods for efficient discrimination of different particles and outline the methods for the quantification of this property. Since a number of comprehensive reviews already exist, we predominantly focus on the detectors currently operated at the LHC. To a lesser extent we also cover some other TRDs, which are planned or are currently being operated in balloon or space-borne astro-particle physics experiments.

    The Juvenile Salmon Acoustic Telemetry System (JSATS) Detector is a software and hardware system that captures JSATS Acoustic Micro Transmitter (AMT) signals. The system uses hydrophones to capture acoustic signals in the water. This analog signal is then amplified and processed by the Analog to Digital Converter (ADC) and Digital Signal Processor (DSP) board in the computer. This board digitizes and processes the acoustic signal to determine if a possible JSATS tag is present. With this detection, the data will be saved to the computer for further analysis. This document details the features and functionality of the JSATS Detector software. The document covers how to install the software, setup and run the detector software. The document will also go over the raw binary waveform file format and CSV files containing RMS values

    The Transition Radiation Detector (TRD) is the main electron detector in ALICE. In conduction with the TPC and the ITS, it provides the necessary electron identification capability to study: - Production of light and heavy vector mesons as well as the continuum in the di-electron channel, - Semi leptonic decays of hadrons with open charm and open beauty via the single-electron channel using the displaced vertex information provided by the ITS, - Correlated DD and BB pairs via coincidences of electrons in the central barrel and muons in the forward muon arm, - Jets with high Pτ tracks in one single TRD stack.

    The KEDR detector is a universal magnetic detector designed for studying the c- and b-quarks and two-photon physics, and is employed at the VEPP-4M e + e - collider. A specific feature of the experiment is the measurement of absolute beam energy using two methods: the resonant depolarization and the faster but less precise Compton backscattering of laser photons. This allowed a large series of measurements to be performed, in which the accuracy of determination of such fundamental parameters of particles as mass and total and leptonic widths was improved.

    We report measurements in a high-energy pion beam of the sensitivity of the edge region in "edgeless" planar silicon pad diode detectors diced through their contact implants. A large surface current on such an edge prevents the normal reverse biasing of the device, but the current can be sufficiently reduced by the use of a suitable cutting method, followed by edge treatment, and by operating the detector at low temperature. The depth of the dead layer at the diced edge is measured to be (12.5±8 stat..±6 syst.) μm.

    2001-01-01

    The liquid argon imaging technique, as proposed for the ICARUS detector, offers the possibility to perform complementary and simultaneous measurements of neutrinos, as those of CERN to Gran Sasso beam (CNGS) and those from cosmic ray events. For the currently allowed values of the Super-Kamiokande results, the combination of both CNGS and atmospheric data will provide a precise determination of the oscillation parameters. Since one can observe and unambiguously identify nu /sub e/, nu /sub mu / and nu /sub tau / components, this technology allows to explore the full (3*3) mixing matrix. The same class of detector can be proposed for high precision measurements at a neutrino factory. (3 refs).

    The PLUME (Pixelated Ladder with Ultra-Low Material Embedding) Collaboration is developing ultra-light ladders for the vertex detector for a future linear collider. The double-sided ladder will integrate the sensors, readout infrastructure and mechanical supports with the aim of total material budget of 0.3% of radiation length. The requirement of as light as possible construction is driven by physics, in particular by measurements requiring determination of the quark charge sign. The first prototype ladders were prepared and tested in the beam. The alignment issues for the ladders will be tested within the AIDA (Advanced European Infrastructures for Detectors at Accelerators) EU FP7 project.

    2010-12-01

    Full Text Available The paper is focused on the European Union (EU trade and trade policy in the time of global financial and economic crisis. The analysis of the EU exports and imports points out that the financial crisis has had a negative impact on the intra as well as on the extra-EU trade in the period 2007-2009, but differences among the EU member states have existed. Although the EU tries to support trade development in the world and remove barriers to trade, some protectionist tendencies were recorded in the time of the economic crisis. The last part of the paper gives emphasis to the EU trade policy and some trade measures which have been taken in the EU and its member states to support trade development or vice versa, to protect domestic industries. The results of the analysis show that, although some protectionist tendencies have been recorded both in extra and intra-EU trade, trade relations which are provided among member states are of significant importance all the time.

  1. Solar Energy: Incentives to Promote PV in EU27

    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.

    Manners, Ian James; Whitman, Richard

    2013-01-01

    The emphasis in this chapter is on the future of EU public diplomacy in a more globalised, mulitipolar, multilateral world. The chapter does not seek to explore the role of EU member states within this future shift but clearly, as Mai’a Davis Cross discusses in her chapter, if the EU and its member...... states are to have a future role at all, they must develop synergies not antergies in external actions and public diplomacy. As the next five sections set out, this fundamental shift in the role of the EU in global politics requires a recognition of how the EU has ‘“gone global’” (section II); how EU...... diplomacy is ‘“going public’” (section III); and how EU public diplomacy needs to consider ‘“sharing minds’” (section IV); how the normative power of public diplomacy can ensure the EU is ‘“remaining distinctive’” in global politics (section V); and before concluding on the normative power approach...

  8. Guidelines for an EU waste management policy

    International Nuclear Information System (INIS)

    The Commission believes that a legally binding Community instrument is the only option, which will give sufficient assurances to European citizens on a high level of nuclear safety. The first objective of the legislative proposals is, therefore, to guarantee a high level of nuclear safety. The proposals will also enable the European nuclear industry to evolve within a stable legal framework. In addition, in a ruling on 10 December 2002, the Court of Justice of the EU stated that there were clear Community competencies for a) the establishment of a legislative and regulatory framework to govern the safety of nuclear installations, b) the implementation of measures relating to the assessment and verification of safety, c) the emergency preparedness and d) the siting of a nuclear installation and the design, construction and operation of nuclear installations. The European Commission, like the NEA and the IAEA, considers that nuclear safety should be looked at as a whole. All the civil nuclear facilities should be addressed, from their design to their end of lifetime, including the radioactive waste. Three fundamental topics for nuclear safety are consequently part of our proposals: the safety of nuclear facilities, the decommissioning of them at the end of their lifetime and the safe management of spent fuel and of radioactive waste. The proposed Waste Directive encourages progress on the safe management of all forms of radioactive waste, but clearly puts the emphasis on the need for greater progress on the safe long-term management of high-level waste and spent fuel. In particular, it urges Member States to develop repositories, in deep geological structures. Programmes will require the selection of at least one site, the launching of the licensing procedure, the building of the repository and its entry into operation. Member States will have to report on this programme at regular intervals. The reports will be subject to peer reviews by national experts. The

    The D0 experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid-argon calorimeters and central muon detector, remaining from Run I, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to D0.

    The author recalls the elevator experiment which ultimately led Einstein to his formulation of General Relativity. In addition to the classical falling weights, flashlights, etc, the author suggests the experimenter also take along a particle detector. This detector will be a particularly simple detector consisting of a Schroedinger particle of mass m in a box with walls impermeable to the detector particle. From the equivalence principle, the detector particle in the accelerated elevator will be in an effective potential maz where z is the coordinate in the direction of the acceleration a, measured from let's say, the center of the detector. The author gives a derivation of the detection process. (Auth.)

    2013-01-01

    The European X-ray Free Electron Laser (XFEL.EU) will provide as-yet-unrivaled peak brilliance and ultra-short pulses of spatially coherent X-rays with a pulse length of less than 100 fs in the energy range between 0.25 and 25 keV. The high radiation intensity and ultra-short pulse duration will open a window for novel scientific techniques and will allow to explore new phenomena in biology, chemistry, material science, as well as matter at high energy density, atomic, ion and molecular physics. The variety of scientific applications and especially the unique XFEL.EU time structure require adequate instrumentation to be developed in order to exploit the full potential of the light source. To make optimal use of the unprecedented capabilities of the European XFEL and master these vast technological challenges, the European XFEL GmbH has started a detector R&D program. The technology concepts of the detector system presently under development are complementary in their performance and will cover the require...

    2012-04-15

    The EU Ecodesign Directive aims at reducing the environmental impact of a number of products sold in the EU, with emphasis on their energy consumption. Ecofys investigated economic benefits related to the Directive. A correct implementation of the EU Ecodesign Directive would yield yearly savings of up to 600 TWh of electricity and 600 TWh of heat in 2020. In addition to these environmental benefits, this study identified important economic advantages like: Net savings for European consumers and businesses of 90 billion euro per year (1% of EU's current GDP) in the year 2020; Reinvesting these savings in other sectors of the economy would result in the creation of one million jobs; Dependency on imports of energy would be reduced by 23% and 37% for natural gas and coal, respectively. This means the EU could slash natural gas imports from Russia by more than half and imports of coal from Russia could be stopped altogether.

  15. Involving the citizens. Radioactive waste management and the EU

    International Nuclear Information System (INIS)

    The European Union (EU) has been often criticized for its democratic deficit, which has been studied in the academic literature at multiple levels: in the polity (macro-level), the institutions (meso-level) and the policies (micro-level) of the EU. The paper presents counter-arguments in favour of the democratic nature of the EU and focuses on the micro-level, particularly the process of implementation of EU policies. Policy implementation and the democratic involvement of citizens are discussed with regard to radioactive waste management and the Directive 2011/70/EURATOM. The Directive's clause on transparency and the recent development of a centre of knowledge for public participation in energy policy implementation by the European Commission (EC) are expression of the democratic nature of the EU and provide further counter-arguments to the claim of democratic deficit.

    2014-05-01

    Full Text Available Although sustainable development plays an important role in EU law, neither EU law nor EU policy clearly explains what the concept means and how it must be put into practice. Policy-makers, NGOs, politicians and businesses do, however, need guidance on sustainable development for the purpose of good policy-making, for effectively holding the EU accountable, and for the design of CSR programmes. To that end, this article will first explain the guidance which EU law and policy already offer on sustainable development. Subsequently, this article will propose (I a more workable definition of sustainable development than the one (the Brundtland definition which is currently used, and (II a framework of application for sustainable development. This framework of application (which will have the form of a sustainability impact assessment provides practical guidance for policy-makers, politicians, NGOs and businesses when dealing with sustainable development in their day-to-day work.

  17. Epistemic Dependence and the EU Seal Ban Debate

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available On September 2009 the European Union (EU adopted a regulation banning the import of seal products into the EU or placing seal products on the EU market. The European Parliament was the main driving force behind the regulation and the EU has been criticised by affected countries outside the EU for not basing this decision on the available expert knowledge. The questions asked are how, given epistemic dependence, non-experts may challenge an expert based policy proposal. Can non-experts hold experts accountable, and if so in what way? Three main tests and ten subtests of expert knowledge are proposed and these tests are then used to assess whether the European Parliament did in fact argue in a way consistent with available expert knowledge in amending the Commission proposal for a regulation.

    The anion photoelectron (PE) spectra of EuH{sup −} and the PE spectrum of overlapping EuOH{sup −} and EuO{sup −} anions are presented and analyzed with supporting results from density functional theory calculations on the various anions and neutrals. Results point to ionically bound, high-spin species. EuH and EuOH anions and neutrals exhibit analogous electronic structures: Transitions from {sup 8}Σ{sup −} anion ground states arising from the 4f{sup 7}σ{sub 6s}{sup 2} superconfiguration to the close-lying neutral {sup 9}Σ{sup −} and {sup 7}Σ{sup −} states arising from the 4f{sup 7}σ{sub 6s} superconfiguration are observed spaced by an energy interval similar to the free Eu{sup +} [4f{sup 7}6s] {sup 9}S - {sup 7}S splitting. The electron affinities (EAs) of EuH and EuOH are determined to be 0.771 ± 0.009 eV and 0.700 ± 0.011 eV, respectively. Analysis of spectroscopic features attributed to EuO{sup −} photodetachment is complicated by the likely presence of two energetically competitive electronic states of EuO{sup −} populating the ion beam. However, based on the calculated relative energies of the close-lying anion states arising from the 4f{sup 7}σ{sub 6s} and 4f{sup 6}σ{sub 6s}{sup 2} configurations and the relative energies of the one-electron accessible 4f{sup 7} and 4f{sup 6}σ{sub 6s} neutral states based on ligand-field theory [M. Dulick, E. Murad, and R. F. Barrow, J. Chem. Phys. 85, 385 (1986)], the remaining features are consistent with the 4f{sup 6}σ{sub 6s}{sup 2}  {sup 7}Σ{sup −} and 4f{sup 7}σ{sub 6s}{sup 7}Σ{sup −} anion states lying very close in energy (the former was calculated to be 0.15 eV lower in energy than the latter), though the true anion ground state and neutral EA could not be established unambiguously. Calculations on the various EuO anion and neutral states suggest 4f-orbital overlap with 2p orbitals in species with 4f{sup 6} occupancy.

    This article explores the rise of the European ‘First Amendment’ beyond national and Strasbourg law, offering a fresh look into the previously under-theorised issue of hate speech in EU law. Building its argument on (1 the scrutiny of fundamental rights protection, (2 the distinction between commercial and non-commercial speech, and, finally, (3 the looking glass of critical race theory, the paper demonstrates how the judgment of the ECJ in the Feryn case implicitly consolidated legal narratives on hate speech in Europe. In this way, the paper reconstructs the dominant European theory of freedom of expression via rhetorical and victim-centered constitutional analysis, bearing important ethical implications for European integration.

    Full Text Available The purpose of the paper is to determine whether after joining European Union, Romanian agriculture became more competitiveness on Unique Market. Romania need significant financial help to solve various structural problems, one of the main problems being the low competitiveness in attracting European funds. Taking all the aspects into consideration, this paper trying to develop an objective analysis of the current state of Romanian agriculture competitiveness, by means of pertinent data and statistics. Competitiveness increase, not only in agriculture, has become a primordial framework of the economic development strategies of most world countries. Agriculture can be an important asset for Romania, in the battle to become more competitive to the European level. Romania should win the market share and increase its exports to the EU market. According to European officials, Romania should find gaps on an already competitive market or to become competitive on new markets.

  1. Explaining Variations in Implementation of EU Directives

    Esther Versluis

    2004-11-01

    Full Text Available Uneven implementation of Community law across the European Union is common practice. Differences in implementation of EU directives differences in degree of domestic adjustment are, according to variables identified in the Europeanization literature, to be explained by variations in the degree of fit and the availability of mediating factors. The analysis of the implementation of the Seveso II and Safety Data Sheets Directives in the Netherlands, Germany, the United Kingdom and Spain shows, however, that these identified factors alone do not suffice to explain the observed differences. This article pleas for a closer look at the role of 'issue salience' as a complementary factor that constraints or stimulates the existing mediating factors in the Europeanization literature.

  2. The EU Comprehensive Approach on Somali Piracy

    2015-07-01

    Full Text Available The Gulf of Aden represents a strategic issue for the international community, as its geographical position is fundamental as the major trade maritime route. About 50 percent of the world container ships pass through the Gulf of Aden each year, 80 percent of those cargos coming from Europe. For this reason, the piracy issue affecting Somalia is a problem affecting EU member states’ security and economy. This paper is focused on the comprehensive approach acted by the European Union, with a special attention on proposing the implementation of programs against illegal fishing and waste dumping in order to fight Somali piracy. The evaluation of the military mission offers an overview on a solution for the near future, while the training missions and the development funds sustain the build-up of national tools and focus on the solving of the roots of the issue.

The interrater reliability for 87 products available on the market in all five Member States was considered...

  4. Containment performance analysis for EU APR1400

    International Nuclear Information System (INIS)

    During a severe accident, as the last barrier of DID (Defense In Depth) strategy, the containment has an important role to limit the release of the radioactive material to environment. The containment should be able to maintain its structural integrity to prevent the release of the radioactive materials contained in it. In this paper, the behavior of pressure and temperature in the containment is evaluated for various accident conditions. EU APR1400 (European APR1400) is equipped with RDS (Rapid Depressurization System), HMS (Hydrogen Mitigation System), SACSS (Severe Accident Containment Spray System), and PECS (Passive Ex vessel Cooling System) to mitigate the severe accident consequences and eventually to keep the containment integrity. Depending on the availabilities of these mitigation systems, the containment undergoes different transients in pressure and temperature

    Land-use changes (intensification, extensification and abandonment) in agriculture and forestry are considered to be the major driving forces for changes in ecosystem function and dynamics, and in landscape patterns in Europe. The aim of the EU project ECOMONT is to investigate the potential risks due to land-use change in the mountainous ecosystem. Fluxes of sensible and latent heat, water vapour, CO{sub 2} and pollutants between the vegetation and the atmosphere are sensitive and critical factors characterising landscape function. The Atmospheric Pollution Section of the PSI contributes to this project with the measurements of these fluxes. The measuring techniques, the experimental setup and first results are presented.

  6. EU Emission Trading - better job second time around?

    International Nuclear Information System (INIS)

    The EU Emission Trading Scheme (EU ETS) for CO2-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

    The F-Gas Ordinance is an important step in minimizing greenhouse-gas emissions. The contribution shows how this can be put into practice. The authors start by presenting the legal framework as well as the sources of F-gases, e.g. electric appliances and trashed vehicles. The situation of implementation into national law of this directive in the various EU member states is discussed. Existing structures are presented, differences are highlighted, and potential obstacles to a harmonized solution are identified. Finally, a producer of refrigerants presents his view of the minimum requirements on an EU-wide system for disposal of fluorinated climate-relevant gases, which should be compatible with existing disposal infrastructures and should focus on prevention rather than recycling and/or disposal.

  11. The CLIC Vertex Detector

    CERN Document Server

    Dannheim, D

    2015-01-01

    The precision physics needs at TeV-scale linear electron-positron colliders (ILC and CLIC) require a vertex-detector system with excellent flavour-tagging capabilities through a meas- urement of displaced vertices. This is essential, for example, for an explicit measurement of the Higgs decays to pairs of b-quarks, c-quarks and gluons. Efficient identification of top quarks in the decay t → W b will give access to the ttH-coupling measurement. In addition to those requirements driven by physics arguments, the CLIC bunch structure calls for hit tim- ing at the few-ns level. As a result, the CLIC vertex-detector system needs to have excellent spatial resolution, full geometrical coverage extending to low polar angles, extremely low material budget, low occupancy facilitated by time-tagging, and sufficient heat removal from sensors and readout. These considerations challenge current technological limits. A detector concept based on hybrid pixel-detector technology is under development for the CLIC ver- tex det...

    P. Paolucci

    2012-01-01

    The RPC system is operating with a very high uptime, an average chamber efficiency of about 95% and an average cluster size around 1.8. The average number of active channels is 97.7%. Eight chambers are disconnected and forty are working in single-gap mode due to high-voltage problems. The total luminosity lost due to RPCs in 2012 is 88.46 pb–1. One of the main goals of 2012 was to improve the stability of the endcap trigger that is strongly correlated to the performances of the detector, due to the 3-out-3 trigger logic. At beginning of 2011 the instability of the detector efficiency was about 10%. Detailed studies found that this was mainly due to the strong correlation between the performance of the detector and the atmospheric pressure (P). Figure XXY shows the linear correlation between the average cluster size of the endcap chamber versus P. This effect is expected for gaseous detectors and can be reduced by correcting the applied high-voltage working point (HVapp) according to the followi...

  3. First ALICE detectors installed!

    CERN Multimedia

    2006-01-01

    Detectors to track down penetrating muon particles are the first to be placed in their final position in the ALICE cavern. The Alice muon spectrometer: in the foreground the trigger chamber is positioned in front of the muon wall, with the dipole magnet in the background. After the impressive transport of its dipole magnet, ALICE has begun to fill the spectrometer with detectors. In mid-July, the ALICE muon spectrometer team achieved important milestones with the installation of the trigger and the tracking chambers of the muon spectrometer. They are the first detectors to be installed in their final position in the cavern. All of the eight half planes of the RPCs (resistive plate chambers) have been installed in their final position behind the muon filter. The role of the trigger detector is to select events containing a muon pair coming, for instance, from the decay of J/ or Y resonances. The selection is made on the transverse momentum of the two individual muons. The internal parts of the RPCs, made o...

  4. Development of new radiation detectors

    International Nuclear Information System (INIS)

    The works on the development of radiation detectors performed at Waseda University are described. As the fundamental studies on radiation detectors, measurement was made for the Z3 dependence of the power of metal targets to stop alpha particles or C-ions, the Fano factor in rare gas, the peak value of the energy given by fast charged particles to materials and its fluctuation, the W-value and the Fano factor of liquid rare gas, and the LET dependence of the luminescence efficiency of liquid rare gas by radiation. The development of liquid rare gas detectors has been made. The considered detector types were a pulse ionization chamber with grid (liquid Xe), a proportional luminescent counter (liquid Xe), an electromagnetic calorimeter (liquid Ar, liquid Xe), and a photo-ionization detector. The development of silicon detectors is also in progress. The silicon detectors under development are a silicon detector telescope for satellite experiment, a silicon shower detector for balloon experiment, and a micron strip silicon detector for synchrotron radiation or elementary particle experiment. The use of plastic track detectors for cosmic ray observation has been examined. The discrimination of isotopes by using a new plastic CR-39 was able to be done. The detectors for low level alpha and gamma spectroscopy have been investigated. For alpha particles, a pulse ionization chamber with a cylindrical grid has been used. For gamma-ray, a Compton-suppressed Ge(Li) detector has been used. (Kato, T.)

  5. PUBLIC DEBT SUSTAINABILITY ANALYSIS: EU CASE

    Directory of Open Access Journals (Sweden)

    Botoc Claudiu

    2011-07-01

    Full Text Available The global crisis has caused a serious fiscal deterioration that leaves the world economy with serious challenges. In many developed markets as well as in a few emerging markets (Emerging markets public finances have already become, or are at least at risk of becoming, unsustainable. Commonly, public debt sustainability is defined as a sovereign's ability to service debt without large adjustments to public revenue and/or expenditure and without ever-increasing public-debt-to-GDP ratios. Hence, this definition refers to both a country's ability and willingness to repay its debt. We also have to add the fact that there isn`t an universal accepted definition of fiscal or debt sustainability. In light of the growing public debt, the issue of debt sustainability has increasingly attracted attention. In this paper we analyse public debt sustainability scenario in EU economies. At least half of the EU countries will have to implement stringent fiscal consolidation programmes over the next few years in order to prevent already high public-debt-to-GDP ratios from a further significant rise, also the case of Romania. However, drastic fiscal policy adjustment may be not feasible in the short term and hence public debt is likely to grow further. In some scenarios the public-debt-to-GDP ratio is predicted to soar to 133% in 2020, from just over 100% in 2010. By contrast, nearly all EM countries, including major economies, appear to be well positioned to stabilise or even outgrow their current debt ratios without drastic fiscal adjustment. Institutional improvements may help European countries to maintain fiscal credibility. In light of the future fiscal challenges, many European governments may introduce new or more effective national debt limits, similar to those put in place in the past with good results by some Emerging markets. Such institutional reforms could help to insulate fiscal policies from political pressure and to anchor financial market

    Reaction between Eu(NO{sub 3}){sub 3} and NH{sub 4}F in aqueous media was applied to produce EuF{sub 3} doughnut-like aggregates with a diameter of 200–500 nm and thickness of 50–150 nm composed of nanoparticles with a mean diameter of 16 nm. The impregnation, sorption and mechanochemical treatment were used for surface modification of EuF{sub 3} doughnut-like particles with 1,10-phenanthroline and sodium dibenzoylmethanate which are sensitizing ligands for Eu{sup 3+} luminescence. The data of transmission electron microscopy, elemental analysis, Fourier transform infrared spectroscopy, and luminescence spectroscopy have proved that the organic ligands are coordinated to surface Eu{sup 3+} ions, forming surface complexes. The surface modification of the EuF{sub 3} nanoparticles with sodium dibenzoylmethanate and 1,10-phenanthroline leads to increase in the luminescence intensity at 612 nm ({sup 5}D{sub 0} → {sup 7}F{sub 2} transition) in comparison with the luminescence intensity of the unmodified EuF{sub 3} nanoparticles. Energy transfer from the ligand to Eu{sup 3+} ion in the surface complexes makes a main contribution to this effect.

    2000-12-01

    One of the most essential means to reach an increased sustainability in the world is to increase the use of economical means and hereby extend the polluter-pay-principle. The EU-commission, OECD and other governments in the EU-countries recommend an increased use of green taxes. This book takes as its starting point the implementation of a green tax reform, where the taxation is moved from tax on manpower to tax on resource consumption and pollution. Hereby both the environmental effort and the economic development are strengthened. The book briefly examines the different definitions of sustainability and outlines the principles for a green tax reform. The elaboration of green taxes, the reversing entry to environmental aims or to the Exchequer, the relation to the social distribution, the financing of the welfare state, the development of the green taxes in the EU countries, removal of environmentally damaging subsidies and the positive effect of the existing green taxes are subjects treated in the book. Finally the book presents a proposal for some Danish possibilities to increase existing green taxes or to introduce new Danish green taxes. (EHS)

    Non-stoichiometric (Eu,Ca):WO3 and Eu:CaWO4 nanoparticles with anti-tumor activity are synthesized in a sol–gel method by adding excessive Eu3+ and Ca2+ ions to tungsten oxide crystal structure. Colorimetric assay shows that 10 nm (Eu,Ca):WO3 and Eu:CaWO4 nanoparticles can effectively inhibit growth of mammary cancer cells without any harm to normal cells. Nanoparticles are characterized by X-ray diffraction, high resolution transmission electron microscopy and fluorescence optical spectrometry. Nanomaterials, insoluble in synthesized water, have complicated self-charging surfaces that trap mammary cancer cells. Surface self-charging effect is suggested as the inhibition mechanism.

    The decays of $^{152m,g}$Eu $\\to ^{152}$Sm have been studied by $\\gamma$-ray spectroscopy using the $8\\pi$ Spectrometer, an array of 20 Compton-suppressed Ge detectors. Very weak $\\gamma$-decay branches in $^{152}$Sm were investigated through $\\gamma - \\gamma$ coincidence spectroscopy. All possible $E2$ transitions between states below 1550 keV with transition energies $> 130$ keV are observed, including the previously unobserved $2^+_3 \\to 0^+_2$ 401 keV transition. The results, combined with existing lifetime data, provide a number of new or revised $E2$ transition strengths which are critical for clarifying the collective structure of $^{152}$Sm and the N=90 isotones.

  17. EU Engagement in the Arctic: Do the Policy Responses from the Arctic States Recognise the EU as a Legitimate Stakeholder?

    Directory of Open Access Journals (Sweden)

    Kamrul Hossain

    2015-11-01

    Full Text Available The Arctic states are bound in an institutional relationship by means of their actions through the Arctic Council (AC—an organisation created by the eight Arctic states. Although a number of its European Union (EU states are both members and observers in the AC, the EU is not, despite its clear stake in the Arctic, for of a number of reasons. The AC twice postponed the application of the EU in 2013; however, it granted the EU the right to observe the AC meetings as an “observer in principle.” In addition to the significant resource and commercial interests of the EU in the Arctic, it assumes a stewardship role in the Arctic. As the leader in combating global climate change, for example, the EU is committed to assuming responsibility for protecting the Arctic environment given that climate change does have a devastating impact in the Arctic. Moreover, the EU is also concerned about its and continental Europe's only indigenous people, the Sámi, a significant proportion of whom live in its Arctic member states of Finland and Sweden. Thus, in recent years, the EU has endorsed a series of policy documents concerning the Arctic. Against the background of this development, this article examines whether the policy responses of the Arctic states with regard to the EU's increased ambition to engage in Arctic matters make it a legitimate actor or stakeholder. The article concludes that even though the Arctic states, as the primary actors, determine the region's governance approach, they see also a general partnership role for the EU with regard to the common goals of knowledge-based responsible governance and sustainable development of the Arctic.
