    The new-generation spectrometer AGATA, the Advanced GAmma Tracking Array, requires sub-nanosecond clock synchronization among readout and front-end electronics modules that may lie hundred meters apart. We call GTS (Global Trigger and Synchronization System) the infrastructure responsible for precise clock synchronization and for the trigger management of AGATA. It is made of a central trigger processor and nodes, connected in a tree structure by means of optical fibers operated at 2Gb/s. The GTS tree handles the synchronization and the trigger data flow, whereas the trigger processor analyses and eventually validates the trigger primitives centrally. Sub-nanosecond synchronization is achieved by measuring two different types of round-trip times and by automatically correcting for phase-shift differences. For a tree of depth two, the peak-to-peak clock jitter at each leaf is 70 ps; the mean phase difference is 180 ps, while the standard deviation over such phase difference, namely the phase equalization repeatability, is 20 ps. The GTS system has run flawlessly for the two-year long AGATA campaign, held at the INFN Legnaro National Laboratories, Italy, where five triple clusters of the AGATA sub-array were coupled with a variety of ancillary detectors

  6. Optimized high energy resolution in γ-ray spectroscopy with AGATA triple cluster detectors

    The AGATA demonstrator consists of five AGATA Triple Cluster (ATC) detectors. Each triple cluster detector contains three asymmetric, 36-fold segmented, encapsulated high purity germanium detectors. The purpose of the demonstrator is to show the feasibility of position-dependent γ-ray detection by means of γ-ray tracking, which is based on pulse shape analysis. The thesis describes the first optimization procedure of the first triple cluster detectors. Here, a high signal quality is mandatory for the energy resolution and the pulse shape analysis. The signal quality was optimized and the energy resolution was improved through the modification of the electronic properties, of the grounding scheme of the detector in particular. The first part of the work was the successful installation of the first four triple cluster detectors at INFN (National Institute of Nuclear Physics) in Legnaro, Italy, in the demonstrator frame prior to the AGATA commissioning experiments and the first physics campaign. The four ATC detectors combine 444 high resolution spectroscopy channels. This number combined with a high density were achieved for the first time for in-beam γ-ray spectroscopy experiments. The high quality of the ATC detectors is characterized by the average energy resolutions achieved for the segments of each crystal in the range of 1.943 and 2.131 keV at a γ-ray energy of 1.33 MeV for the first 12 crystals. The crosstalk level between individual detectors in the ATC is negligible. The crosstalk within one crystal is at a level of 10{sup -3}. In the second part of the work new methods for enhanced energy resolution in highly segmented and position sensitive detectors were developed. The signal-to-noise ratio was improved through averaging of the core and the segment signals, which led to an improvement of the energy resolution of 21% for γ-energies of 60 keV to a FWHM of 870 eV. In combination with crosstalk correction, a clearly improved energy resolution was

    High-resolution gamma-ray detectors based on high-purity germanium crystals (HPGe) are one of the key workhorses of experimental nuclear science. The technical development of such detector technology has been dramatic in recent years. Large volume, high-granularity, electrically segmented HPGe detectors have been realised and a methodology to improve position sensitivity using pulse-shape analysis coupled with the novel technique of gamma-ray tracking has been developed. Collaborations have been established in Europe (Advanced GAmma Tracking Array (AGATA)) [J. Simpson, Acta Phys. Pol. B 36 (2005) 1383] and the USA (GRETA/GRETINA) [C.W. Beausang, Nucl. Instr. and Meth. B 204 (2003)] to build gamma-ray tracking spectrometers. This paper discusses the performance of the first AGATA asymmetric detector that has been tested at the University of Liverpool. The use of a fully digital data acquisition system has allowed detector charge pulse shapes from a selection of well-defined photon interaction positions to be analysed, yielding important information on the position sensitivity of the detector.

  13. Gamma ray tracking with the AGATA demonstrator. A novel approach for in-beam spectroscopy

    The Advanced GAmma Tracking Array (AGATA) employs the novel method of γ-ray tracking (GRT), where all locations of energy depositions within the Ge crystal detector volume are used by computer algorithms to reconstruct the various simultaneous interactions of the measured radiation. The interaction positions are determined by Pulse Shape Analysis (PSA) algorithms that compare the measured and digitized signals with the information of a signal database comprising position dependent calculated sets of detector signals. The result of a detailed comparison between measured and calculated signals yields the position of each interaction point. The GRT algorithms rely on this precise position of the deposited energy as an input to reconstruct the initial γ-rays from the full sequence of the different interactions in the detector. Within this thesis a computer program library was developed, providing software routines to calculate the position dependent detector signals of the highly segmented HPGe detectors. The currently used signal databases of all AGATA detectors were generated by this software package and computer library. Part of the computing is based on individual detector properties which were deduced from detailed characterisation measurements. Details of the library, the used routines and the needed characteristics of the detector system are described, this includes a precise measurement of the crystal axis orientation of the AGATA HPGe crystals. The second part of this thesis is dealing with the analysis of one of the first in-beam experiments performed with the AGATA demonstrator setup at the LNL in Italy. The experiment aimed for a spectroscopic investigation of neutron rich actinides from Thorium to Plutonium produced after multi-nucleon transfer reactions. For this purpose a 136 Xe beam with an energy of 1 GeV bombarded onto a 238 U target. The fast beam like particles after the transfer reactions were identified by the magnetic spectrometer PRISMA.

    Available studies on surrogacy are extremely limited. Findings suggest that surrogacy is experienced as problem free, with a significant number of commissioning mothers maintaining contact with the surrogates over time. To explore the experiences of Greek commissioning women regarding the surrogacy arrangement and birth of a child through surrogacy. The data of this study were collected from 7 intended mothers who had either a long history of infertility or serious health problems. Interviews were tape-recorded, transcribed and analysed employing content analysis. The analysis of the women's accounts revealed three themes: (a) a shared journey, (b) the birth of a long-awaited child, and (c) the surrogacy disclosure. The surrogacy process became the women's affairs, with their partners offering backstage support. A very close bond was developed with the surrogates, characterised by daily contacts and care-giving behaviours. While this bond was abruptly discontinued after the child's birth, it was interiorised with all participants being grateful to their surrogate. The timing and content of the surrogacy disclosure to family and child(ren) were carefully chosen by participants, who avoided providing information when egg donation was involved. Findings are reassuring for women who want to parent a child through a surrogate arrangement, and suggest that the availability of counselling services may help intended mothers to cope with disclosure issues.

    The main objective of the Advanced GAmma Tracking Array (AGATA) is the investigation of the structure of exotic nuclei at the new generation of RIB facilities. As part of the preparatory phase for FAIR-NUSTAR, AGATA is going to be installed at the FRS fragmentation facility of the GSI centre for an experimental campaign to be performed in 2012 and 2013. Owing to its γ-ray tracking capabilities and the envisaged enhancement in resolving power, a series of in-flight γ-ray spectroscopy experiments are being planned. The present work describes the conceptual design of this first implementation of AGATA at GSI-FRS, and provides information about the expected performance figures. According to the characteristics of each particular experiment, it is foreseen that the target-array distance is adjusted in order to achieve the optimum compromise between detection efficiency and energy resolution, or to cover an specific angular range of the emitted electromagnetic radiation. Thus, a comprehensive Monte Carlo study of the detection sensitivity in terms of photopeak efficiency, resolution and peak-to-total ratio, as a function of the target-array distance is presented. Several configurations have been investigated, and MC-calculations indicate that a remarkable enhancement in resolving power can be achieved when double-cluster AGATA detectors are developed and implemented. Several experimental effects are also investigated. This concerns the impact of passive materials between the target and the array, the angular distribution of the detection efficiency and the influence of target thickness effects and transition lifetimes in the attainable detection sensitivity. A short overview on half-life measurements via lineshape effects utilizing AGATA is also presented.

    The AEgIS Experiment is an international collaboration based at CERN whose aim is to perform the first direct measurement of the gravitational acceleration g of antihydrogen in the gravitational field of the Earth. Cold antihydrogen will be produced with a pulsed charge exchange reaction in a cylindrical Penning trap where antiprotons will be cooled to 100mK. The cold antihydrogen will be produced in an excited Rydberg state and subsequently formed into a beam. The deflection of the antihydrogen beam will be measured by using Moire deflectometer gratings. After being approved in late 2008, AEgIS started taking data in a commissioning phase early 2012. This report presents an overview of the AEgIS experiment, describes its current status and shows the first measurements on antiproton catching and cooling in the 5 T Penning catching trap. We will also present details on the techniques needed for the 100mK antihydrogen production, such as pulsed positronium production and its excitation with lasers.

  3. Lifetime measurement in the mass region A∼100 with the PreSPEC-AGATA setup

    2015-06-24

    Mid-shell nuclei in the mass region A∼100 show collective behavior. For instance, neutron rich even-even molybdenum isotopes are associated with a shape-phase transition. A spherical vibrator nucleus is observed for N=48 neutrons, while measurements indicate a deformed rotor nucleus for N=64 neutrons. In order to characterize the shape of molybdenum nuclei better, thus the shape-phase transition in molybdenum isotopes, a PreSPEC-AGATA experiment was performed at GSI. In particular, the experiment aimed at measuring the lifetime of the 4{sup +}{sub 1} excited state of {sup 108}Mo to deduce the decay transition rate of the 4{sup +}{sub 1} state. The production of {sup 108}Mo was performed in two steps. First, the GSI Fragment-Separator (FRS) selected {sup 109}Tc ions produced via fission of a {sup 238}U beam. Then, {sup 109}Tc ions underwent a fragmentation reaction on a beryllium secondary target. Half-speed of light fragments produced in this second reaction were identified by the Lund-York-Cologne CAlorimeter (LYCCA). γ-rays were detected by the AGATA array positioned around the secondary target at forward angles. A complex electronics and data-acquisition system was set up to record the coincidences between a flying ion and the γ-rays it emitted. The interaction position of γ-rays inside an AGATA crystal is determined with good resolution. Therefore, combined with the large Doppler shift of the γ-ray, it provides a unique possibility to measure lifetime with the Geometrical-Doppler-Shift-Attenuation method. From the data analysis which included several new techniques, the half-life of T{sub 1/2}=11{sup +16}{sub -6} ps was extracted for the first 4{sup +}{sub 1} state of {sup 108}Mo. The statistics recorded in this experiment is relatively low which leads to a large uncertainty on this measurement. With this large uncertainty, it is not possible to conclude on the exact behavior of the {sup 108}Mo nucleus, even though the comparison of our measurement with

    After completing design, construction, commissioning, operation and maintenance experience of the reprocessing plants at Tarapur, Mumbai and Kalpakkam a new reprocessing plant is commissioned and put into operation at BARC, Tarapur since 2011. Subsequent to construction clearance, commissioning of the plant is taken in many steps with simultaneous review by design and safety committees. In spite of vast experience, all the staff was retrained in various aspects of process and utility operations and in operation of innovative changes incorporated in the design. Operating personnel are licensed through an elaborate procedure consisting of various check lists followed by personnel interview. Commissioning systems were divided in sub-systems. Sub-systems were commissioned independently and later integrated testing was carried out. For commissioning, extreme operating conditions were identified in consultation with designers and detailed commissioning procedures were made accordingly. Commissioning was done in different conditions to ensure safety, smooth operation and maintainability. Few modifications were carried out based on commissioning experience. Technical specifications for operation of the plant are made in consultation with designers and reviewed by safety committees. Operation of the plant was carried out after successful commissioning trials with Deep Depleted Uranium (DDU). Emergency operating procedures for each design basis accident were made. Performance of various systems, subsystems are quite satisfactory and the plant has given very good capacity factor. (author)

    There are a few studies about commissioning mothers' understanding from the surrogacy during 9 months of waiting for delivery in Iran and other countries. This study was conducted with an aim to explore and explain the nature of concerns (experiences) of commissioning mothers. A qualitative design with a conventional content analysis approach was used to gather and analyze the experiences of commissioning mothers. They were selected from Royan Research Centre and other infertility centers in Iran. After purposive sampling for the selection of the participants, unstructured interviews were held for data collection. Twenty-four unstructured interviews were conducted with 12 commissioning mothers, 2 surrogate mothers, and 2 infertility center social workers who directly and continuously dealt with these mothers. TWO MAIN THEMES EMERGED FROM THE DATA ANALYSIS: 1. cultural dilemma (consisting of three subthemes: Social taboo, concerns about disclosure to others and the child, concerns about altering maternal and child's identity, and 2. uncertain waiting (consisting of three subthemes: Concerns about health of fetus and surrogate, concerns about an unfamiliar surrogate, and concerns about lack of preparation for maternal role). The study reveals the importance of maternal emotional care in this group and introduces a new arena for nurses' activity. These findings help the mothers by nurses' activities in health care clinics and anywhere they deliver nursing care.

Materials and Methods: A qualitative design with a conventional content analysis approach was used to gather and analyze the experiences of commissioning mothers. They were selected from Royan Research Centre and other infertility centers in Iran. After purposive sampling for the selection of the participants, unstructured interviews were held for data collection. Twenty-four unstructured interviews were conducted with 12 commissioning mothers, 2 surrogate mothers, and 2 infertility center social workers who directly and continuously dealt with these mothers. Results: Two main themes emerged from the data analysis: 1. cultural dilemma (consisting of three subthemes: Social taboo, concerns about disclosure to others and the child, concerns about altering maternal and child's identity, and 2. uncertain waiting (consisting of three subthemes: Concerns about health of fetus and surrogate, concerns about an unfamiliar surrogate, and concerns about lack of preparation for maternal role). Conclusions: The study reveals the importance of maternal emotional care in this group and introduces a new arena for nurses’ activity.

    Starting this summer, Fermilab will host a key experiment dedicated to the search for signals of new physics: The Fermilab Muon g-2 Experiment. Its aim is to precisely measure the anomalous magnetic moment of the muon. In full operation, in order to avoid contamination, the newly born secondary beam is injected into a 505 m long Delivery Ring (DR) wherein it makes several revolutions before being sent to the experiment. Part of the commissioning scenario will execute a running mode wherein the passage from the DR will be skipped. With the aid of numerical simulations, we provide estimates of the expected performance.

    In order to ease the management of their infrastructure, most of the WLCG sites are adopting cloud based strategies. In the case of CERN, the Tier 0 of the WLCG, is completely restructuring the resource and configuration management of their computing center under the codename Agile Infrastructure. Its goal is to manage 15,000 Virtual Machines by means of an OpenStack middleware in order to unify all the resources in CERN's two datacenters: the one placed in Meyrin and the new on in Wigner, Hungary. During the commissioning of this infrastructure, CERN IT is offering an attractive amount of computing resources to the experiments (800 cores for ATLAS and CMS) through a private cloud interface. ATLAS and CMS have joined forces to exploit them by running stress tests and simulation workloads since November 2012. This work will describe the experience of the first deployments of the current experiment workloads on the CERN private cloud testbed. The paper is organized as follows: the first section will explain the integration of the experiment workload management systems (WMS) with the cloud resources. The second section will revisit the performance and stress testing performed with HammerCloud in order to evaluate and compare the suitability for the experiment workloads. The third section will go deeper into the dynamic provisioning techniques, such as the use of the cloud APIs directly by the WMS. The paper finishes with a review of the conclusions and the challenges ahead.

    The ATLAS Semiconductor Tracker (SCT) has been installed, and fully connected to electrical, optical and cooling services. Commissioning has been performed both with calibration data and cosmic ray events. The cosmics were used to align the detector, measure the hit efficiency and set the timing. The SCT is now ready to take data when the LHC turns on this autumn. At the same time, it is clear that the present ATLAS tracker will need to be renewed for projected luminosity upgrade of the LHC, the SLHC. This is mainly driven by occupancy and radiation hardness issues. The new tracker will likely be entirely made of silicon, with the space of the present SCT largely taken up by detectors with much shorter strips. Several large-scale R and D projects on the sensors and module concepts for this upgrade are running, including sensor and module prototyping. We will report upon the commissioning experience from the SCT, use it to extract valuable lessons for future silicon tracker projects, and give an up-to-date overview of the status and results of the R and D efforts for the ATLAS tracker upgrade.

    This work presents the neutronic calculation results, most of which were carried out after such experiences, to verify the calculation methodology developed at the Analysis and Calculation Department of the National Atomic Energy Commission (CNEA). The results obtained were satisfactory, proving that the calculation methodology used is adequate for the design of this type of reactors. The only important disagreement is to evaluate the reactivity excess and cut reactivity, but this responds to a criterion difference and/or that of definition for these parameters. The positions of criticality with errors lower than 100 pcm were predicted. The differential and integral reactivities for the calibration of bars, as well as the flux distribution, are reproduced in a reasonable degree in relation to differences inferior to 10%.

  1. Nuclear structure studies towards superheavy elements and perspectives with AGATA

    International Nuclear Information System (INIS)

    Korichi, A.

    2005-01-01

    A variety of theoretical approaches have been used to calculate the shell closure of spherical Super Heavy Elements (SHE) but the predictions of the location of the 'island of stability' vary from Z=114 to 120 and 126, with neutron numbers around N=172 or N=184 depending on the model employed. A deformed minimum around Z=108 and N=162 is predicted and an increase of the half-life of Hassium (Z=108) is experimentally observed when approaching the neutron number N=162. Super heavy nuclei are produced with very low cross-section (a few picobarns) and this makes their spectroscopic study impossible with today's beam intensities and detectors. However, important information can be obtained from the structure of mid-shell deformed nuclei (Z∼104) where selected single particle orbitals, which lie close to the spherical shell gap in SHE, are close to the Fermi level. The information will come from decay and in-beam spectroscopy. A promising area of progress, using the state-of-the art instruments, is represented by the observation of rotational gamma-ray transitions in No and Fm isotopes showing the deformed character of these nuclei. One of the objectives and focus of the nuclear structure community is related to the investigation of Single particle excitations beyond the N=152 neutron gap and collective properties of heavier systems towards Z∼104. The IN2P3-JINR collaboration has launched a project of electron and gamma-ray spectroscopy studies of heavy nuclei at the FLNR. This project benefits from the radioactive actinide targets uniquely available at Dubna and from the very intense stable beams provided by the U400 cyclotron. This offers a unique opportunity for the study of nuclei above Z=100 along an isotopic chain approaching N=162. In this contribution, the emphasis will be on the GABRIELA project and its issues. I will finally point out the perspectives with the new generation of gamma detectors such as AGATA

    Objectives To explore the 'added value' that general practitioners (GPs) bring to commissioning in the English NHS. We describe the experience of Clinical Commissioning Groups (CCGs) in the context of previous clinically led commissioning policy initiatives. Methods Realist evaluation. We identified the programme theories underlying the claims made about GP 'added value' in commissioning from interviews with key informants. We tested these theories against observational data from four case study sites to explore whether and how these claims were borne out in practice. Results The complexity of CCG structures means CCGs are quite different from one another with different distributions of responsibilities between the various committees. This makes it difficult to compare CCGs with one another. Greater GP involvement was important but it was not clear where and how GPs could add most value. We identified some of the mechanisms and conditions which enable CCGs to maximize the 'added value' that GPs bring to commissioning. Conclusion To maximize the value of clinical input, CCGs need to invest time and effort in preparing those involved, ensuring that they systematically gather evidence about service gaps and problems from their members, and engaging members in debate about the future shape of services.

In this report the authors illustrate the results achieved so far and the difficulties encountered in commissioning, with the hope that this material might be some of help to those who intend to start the enterprise of building a SC linac in a non specialized environment. The part concerning the SC system is particularly stressed, but a relevant attention is also devoted to the traditional room temperature injector, the proper setting of which is fundamental to achieving the high beam quality that such a machine allows

    The DSP-based bunch-by-bunch feedback system installed in the PEP-II HER has been used to damp HOM-induced instabilities at beam currents up to 6-5 mA during commissioning. Beam pseudospectra calcualted from feedback system data indicate the presence of coupled bunch modes that oincide with the 0-M-2 cavity HOM. Bunch current and synchronous phase measurements are also extracted from the data. These measurements reveal the impedance seen by the beam at revolution harmonics. The impedance peak at 3*frev indicates incorrect parking of the idle cavities, and explains the observed instability of mode 3. Bunch synchrotron tunes are calculated from lorentzian fits to the data. Bunch-to-bunch time variation due to the cavity transient is shown to be large enough to result in Landau damping of coupled bunch modes

    The AGATA Detector Library (ADL) was developed for the calculation of signals from highly segmented large volume high-purity germanium (HPGe) detectors. ADL basis sets comprise a huge amount of calculated position-dependent detector pulse shapes. A basis set is needed for Pulse Shape Analysis (PSA). By means of PSA the interaction position of a γ -ray inside the active detector volume is determined. Theoretical concepts of the calculations are introduced and cover the relevant aspects of signal formation in HPGe. The approximations and the realization of the computer code with its input parameters are explained in detail. ADL is a versatile and modular computer code; new detectors can be implemented in this library. Measured position resolutions of the AGATA detectors based on ADL are discussed. (orig.)

The next major step in gamma-ray spectroscopy involves achieving the goal of a 4pi ball of Germanium detectors by using the technique of gamma-ray energy tracking in electrically segmented Germanium crystals. The resulting spectrometer will have an unparalleled level of detection power for nuclear electromagnetic radiation. Collaborations have been established in Europe (AGATA) [J. Simpson, Acta Phys.

    Data from the highly segmented High-Purity Germanium (HPGe) detectors of the AGATA spectrometer show that segments are more sensitive to neutron damage than the central core contact. Calculations on the collection efficiency of charge carriers inside the HPGe detector were performed in order to understand this phenomenon. The trapping sensitivity, an expression based on the collection efficiencies for electrons and holes, is put forward to quantify the effect of charge carrier trapping. The sensitivity is evaluated for each position in the detector volume with respect to the different electrodes and the collected charge carrier type. Using the position information obtained by pulse shape analysis from the position-sensitive AGATA detectors, it is possible to correct for the energy deficit employing detector specific sensitivity values. We report on the successful correction of the energy peaks from heavily neutron-damaged AGATA detectors for core and segment electrode signals. The original energy resolution can optimally be recovered up to a certain quantifiable limit of degradation due to statistical fluctuations caused by trapping effects. (orig.)

    To evaluate the measured of all photon beam data of first Varian True Beam version 2.0 slim model, recently commissioned at Nordland Hospital Trust, Bodø. To compare and evaluate the possibility of beam matching with the Clinac2300, for the energies of 6MV and 15 MV. Materials/Methods: Measurements of PDD, OAR, and Output factors were realized with the IBA Blue-phantom with different detectors and evaluated between them for all photon energies: 6MV, 15MV, 6MV FFF and 10MV FFF. The ionization chambers used were Pin Point CC01, CC04, Semiflex CC13 and photon diode by Iba dosimetry. The data were processed using Beizer algorithm with a resolution of 1 mm. The measured depth dose curves, diagonals, OAR, and output factors were imported into Eclipse in order to calculate beam data for the anisotropic analytical algorithm (AAA version 10.0.28) for both the dataset measured with CC04 and CC13 and compared. The model head of 23EX was selected as the most near model to True Beam as a restriction of our version of Aria. It was seen that better results were achieved with the CC04 measured data as a result of better resolution. For the biggest field after 10 cm depth a larger difference is seen between measured and calculated for both dataset, but it is within the criteria for acceptance. Results: The Beam analysis criteria of 2 mm at 50% dose is achieved for all the fields accept for 40x40 that is within 3%. Depth difference at maximum dose is within 1 mm for all the fields and dose difference at 100 mm and 200 mm is lower than 1% for or all the fields. The PDD between two machines for all the fields differ after Dmax with less than 1%. For profiles in the field zone and outside field the difference is within 1% for all the fields. In the penumbra region the difference is from 2% up to 12% for big fields. As for diagonals they differ as a result of the head construction at the edge of the field and the penumbra region. The output factors differ for big fields

    In order to conduct the production experiments with polarized deuterium target and (un)polarized proton beam at ANKE/COSY, a commissioning experiment of the polarized internal target with deuterium is imperative. The commissioning experiment includes the measurements of both the vector (Q{sub y}) and tensor (Q{sub yy}) polarization of the deuterium gas target through the nuclear reactions with large and well known analyzing powers, which can be detected in ANKE. The dependence of the polarizations along the storage cell is also determined. The poster presents the physics case for the experiments with deuterium polarized internal target and the apparatus needed for the commissioning experiment, as well as the procedure of extraction for spin observables.

    Reorganization and dismantling have been part of the CEA's facility renewal process for more than twenty years now. Many facilities have already been downrated or will be in the near future. The strategy developed so far is founded on acquired experience, on the basis of which it may be said that: nuclear facilities are reversible in full and strict compliance with safety and security rules; a field of competence has been developed that will help French industries to land on their feet when the time comes on the dismantling market; public opinion has been informed as to the soundness of the energy alternatives chosen

    The ALPHA experiment at CERN creates antihydrogen by mixing antiproton and positron plasmas. Diagnostic measurements of the precursor plasmas are performed using a diagnostic suite, colloquially known as the ``stick.'' This stick has a variety of sensors and is able to move to various heights to align the desired diagnostic with the beamline. A cylindrical electrode, a faraday cup, an electron gun, and a microchannel-plate detector (MCP) are regularly used to control and diagnose plasmas in ALPHA. We have designed, built, and tested a new, upgraded stick which includes measurement capabilities in both beamline directions.

    The SLC Arc System is designed to transport beams of electrons and positrons from the end of the SLAC Linac to the beginning of the Final Focus System where they are made to collide head on. To minimize phase space dilution caused by quantum processes in the synchrotron radiation energy loss mechanism, the bending radii are large (279 m) and very high gradient (n = 32824) AG cells are arranged in trains of low dispersion, terrain following achromats. First experiences in operating a system of over 900 magnets, each with beam position monitors and corrector magnet movers, spanning 9000 feet, are described

    The reconstruction of the missing mass is limited by the position and momentum resolution of the HERMES spectrometer. In order to reach a higher accuracy in the measurements the backscattered nucleon must also be detected. A detector suited for this must give the possibility, to determine the momentum of the particles over a very large range: from minimally ionizing particles up to protons, which are stopped in the detector. The detector must also be able to discriminate hadrons and mesons as well as cover the complete spatial region around the target. In the winter 2005-2006 such a recoil detector was installed in the HERMES experiment. The detector sonsists of three partial detectors, a silicon counter within the scattering chamber, a sintillating-fiber detector and a photon detector. Before the installation of the detector the silicon modules were tested in a bench test and checked together with the other particle detectors in a test experiment. A large part of this dissertation is dedicated to the planning and performance of these tests as well to the evaluation of them. It could be show, that the modules worked accordly to their specifications, however because of unexpectedly high noise a signal correction became necessary. Different models for the correction were developed and tested in the framework of these thesis. In spite of the high noise cosmic muons could be detected and their energy deposition measured with a signal-to-noise ratio of 2:1. In the winter break 2005-2006 the recoil detector was installed into the HERMES experiment. First diagnosis and analysis software was developed. The silicon detector measured successfully energy depositions of minimally ionizing particles up to protons stopped in the sensor. Minimally ionizing particles could be detected with a signal-to-noise ratio of 5:1. By means of track information of the scintillating-fiber detector protons could be discriminated from pions and other mesons by the silicon detector. The HERMES

    The CMS Collaboration conducted a month-long data-taking exercise known as the Cosmic Run At Four Tesla in late 2008 in order to complete the commissioning of the experiment for extended operation. The operational lessons resulting from this exercise were addressed in the subsequent shutdown to better prepare CMS for LHC beams in 2009. The cosmic data collected have been invaluable to study the performance of the detectors, to commission the alignment and calibration techniques, and to make several cosmic ray measurements. The experimental setup, conditions, and principal achievements from this data-taking exercise are described along with a review of the preceding integration activities.

    The development of highly segmented germanium detectors as well as the algorithms to identify the position of the interaction within the crystal opens the possibility to locate the γ-ray source using Compton imaging algorithms. While the Compton-suppression shield, coupled to the germanium detector in conventional arrays, works also as an active filter against the γ rays originated outside the target, the new generation of position sensitive γ-ray detector arrays has to fully rely on tracking capabilities for this purpose. In specific experimental conditions, as the ones foreseen at radioactive beam facilities, the ability to discriminate background radiation improves the sensitivity of the gamma spectrometer. In this work we present the results of a measurement performed at the Laboratori Nazionali di Legnaro (LNL) aiming the evaluation of the AGATA detector capabilities to discriminate the origin of the γ rays on an event-by-event basis. It will be shown that, exploiting the Compton scattering formula, it is possible to track back γ rays coming from different positions, assigning them to specific emitting locations. These imaging capabilities are quantified for a single crystal AGATA detector.

    The NEutron Detector Array (NEDA) project aims at the construction of a new high-efficiency compact neutron detector array to be coupled with large γ-ray arrays such as AGATA. The application of NEDA ranges from its use as selective neutron multiplicity filter for fusion-evaporation reaction to a large solid angle neutron tagging device. In the present work, possible configurations for the NEDA coupled with the Neutron Wall for the early implementation with AGATA has been simulated, using Monte Carlo techniques, in order to evaluate their performance figures. The goal of this early NEDA implementation is to improve, with respect to previous instruments, efficiency and capability to select multiplicity for fusion-evaporation reaction channels in which 1, 2 or 3 neutrons are emitted. Each NEDA detector unit has the shape of a regular hexagonal prism with a volume of about 3.23l and it is filled with the EJ301 liquid scintillator, that presents good neutron- γ discrimination properties. The simulations have been performed using a fusion-evaporation event generator that has been validated with a set of experimental data obtained in the 58Ni + 56Fe reaction measured with the Neutron Wall detector array.

    The commissioning of nine Magnox and two Advanced Gas-cooled Reactor Nuclear Power Plants in the United Kingdom during the last sixteen years under the regulatory control of the Nuclear Installations Inspectorate of the Health and Safety Executive has been based on a Stage Approval Philosophy starting with proof-testing of the primary gas circuit and concluding with tests on the reactor at full power. The practical experience gained during this period has enabled the Nuclear Installations Inspectorate to rationalise the procedures and test requirements without comporomising safety standards. The Operating Rules and Maintenance Schedules are approved for commissioning and during this period are reviewed for their adequacy for future power operation of the plant. The organisation, documentation, test procedures and the commissioning programme used for the Advanced Gas-cooled Reactors are briefly explained. (author)

    The RHIC Beam Abort Kicker Power Supply Systems commissioning experience and the remaining issues will be reported in this paper. The RHIC Blue Ring Beam Abort Kicker Power Supply System initial commissioning took place in June 1999. Its identical system in Yellow Ring was brought on line during Spring 2000. Each of the RHIC Beam Abort Kicker Power Supply Systems consists of five high voltage modulators and subsystems. These systems are critical devices for RHIC machine protection and environmental protection. They are required to be effective, reliable and operating with sufficient redundancy to safely abort the beam to its beam dump at the end of accumulation or at any time when they are commanded. To deflect 66 GeV ion beam to the beam absorbers, the RHIC Beam Abort Kicker Power Supply Systems were operated at 22 kV level. The RHIC 2000 commissioning run was very successful

    In this paper authors describe the experience gained during commissioning and trial operation of Mochovce NPP (EMO). The first year of EMO operation from the point of view of safety and reliability was successful. Evidently we were challenged with certain problems characteristic to this stage of operation which resulted in automatic reactor shutdown. There were 11 automatic shutdowns in 1998 by action of the quick emergency protection AO-1 and two manual shutdowns by the AO-1 key. In 1999, there were 6 automatic shutdowns by action of the quick emergency protection AO-1. Three of them was connected to the falsely activated binary signal of MCP switch of, in two cases the reason came out from the turbo-generator (TG) cooling water system. Very positive trend in the operation of both units shows the fact that during all commissioning period of the second unit there were only three automatic reactor shutdowns by the signal AO-1. All these actions were done in frame of commissioning tests. All causes which activated the automatic unit shutdowns were found out and rectified, the overall tuning of the cooling water system is on the process now. The solution of this problem is possible only power commissioning, and in the stage of the trial operation had no direct impacts on the nuclear, radiation, or technical safety respectively. In 1998 two events according to the INES scale after second unit commissioning because of two unit links of the cooling water system. The operational events during the commissioning tests, start-up tests, physical commissioning, were ranked the category 1 ('Action of SIS U040 p po <8,34 MPa at the system 2 and 3' and 'Breaching the L and C'). In 1999 only events occurred that were ranked in the category safety insignificant events and lower (category 0, or off the scale respectively). In the frame of the safety culture principles adopted, such as critical attitude, exact and careful approach, and communication, these problems were given the

  12. Construction and commissioning experience of evolutionary water cooled nuclear power plants

    Electricity market liberalization is an established fact in several countries and there is a trend to adopt it in other countries. The essential aim of market liberalization is to improve the overall economic efficiency. In order that nuclear power remains a viable option for electricity generation, its costs should be competitive with alternative sources while, at the same time, it should have a safe and reliable operation record. The capital cost of nuclear power plants (NPPs) generally accounts for 43-70% of the total nuclear electricity generation costs, compared to 26-48% for coal plants and 13-32% for gas plants. Most of these expenditures are incurred during the construction phase of a NPP. The achievement of shorter construction periods using improved technology and construction methods has a significant benefit on the costs incurred prior to any production of electricity. This document is intended to make the recent worldwide experience on construction and commissioning of evolutionary water cooled NPPs available to Member States and especially to those with nuclear power plants under construction/planning, and to those seriously considering nuclear power projects in the future. The final aim is to assist utilities and other organizations in Member States to improve the construction of nuclear power plants and achieve shortened schedules and reduced costs without compromising quality and safety. This document aims to provide an overview of the most advanced technologies, methods and processes used in construction and commissioning of recent nuclear projects. To better achieve this objective the presentation is selectively focused more on the new developments rather than providing a full review of all issues related to construction and commissioning. The experience described in this TECDOC applies to managers, engineers, supervisors, technicians and workers in various organizations dealing with the site construction and commissioning of nuclear power plants

    In the German Democratic Republic two nuclear power plants equipped with four pressurized-water WWER-440-type reactors were commissioned in the years 1973-1979 and have since been in routine operation. The nuclear power plants (NPPs) in the GDR were constructed on the basis of projects developed and tested in the Soviet Union. Their main equipment was also supplied by the USSR. Under the technical supervision of USSR scientific institutions and design organizations, the construction, commissioning and operation of NPPs had to be prepared and organized by the design organizations, scientific institutions and the prospective user in the German Democratic Republic. To this effect, and to ensure nuclear safety, availability and maximum exploitation of nuclear fuel, it was necessary to develop national scientific capacities. The organizations of the USSR supply basic and supplementary documents prescribing the required extent of investigations to prove that the equipment and systems will meet the projected and operational conditions from loading to commercial operation. Concrete test programmes for commissioning and operational instructions are elaborated by national organizations. Pre-operational and initial startup tests are performed by the personnel of the plant, of enterprises and scientific institutions under the technical supervision of the design organizations of the USSR and the German Democratic Republic. Proceeding from experience gained for more than 15 years in the scientific support of commissioning and operation, the required training and disciplines of personnel are reported. The tasks to be met by the various disciplines are described. Furthermore, information is given on the main stages of commissioning and on a number of results. Finally, selected results of work in connection with operational assistance are reported

    A new experimental setup to measure prompt-delayed γ-ray coincidences from isotopically identified fission fragments, over a wide time range of 100 ns-200 μs, is presented. The fission fragments were isotopically identified, on an event-by-event basis, using the VAMOS++ large acceptance spectrometer. The prompt γ rays emitted at the target position and corresponding delayed γ rays emitted at the focal plane of the spectrometer were detected using, respectively, thirty two crystals of the AGATA γ-ray tracking array and seven EXOGAM HPGe Clover detectors. Fission fragments produced in fusion and transfer-induced fission reactions, using a {sup 238}U beam at an energy of 6.2 MeV/u impinging on a {sup 9}Be target, were used to characterize and qualify the performance of the detection system.

    The next generation of γ-ray spectrometers like AGATA will provide high quality γ-ray spectra by the new Gamma-Ray Tracking technique (GRT). Position sensitive HPGe detectors will allow for precise Doppler correction and small broadening of lines for spectroscopy at relativistic energies. GRT is based on the interaction position of the γ-rays within the volume of the highly segmented germanium detectors provided by Pulse Shape Analysis (PSA) methods. The proof of principle of GRT was already demonstrated with great success however systematic deviations from expected results occur. The parameterization of the following detector properties and their impact on PSA were thoroughly investigated and optimized: electron and hole mobility, crystal axis orientation, space charge distributions, crystal impurities, response functions of preamplifiers and digitizers, linear and differential crosstalk, time alignment of pulses and the distance metric. Results of an improved PSA performance are presented.

    Agata is the European project for a 4π gamma-ray tracking array of 180 Ge detectors and is expected to have a detection sensitivity higher by 3 orders of magnitude than that of the present generation of gamma spectrometers. The trajectories of the photons inside a Ge crystal are reconstituted, which allows the determination of the initial energy of the incident photons as the total energy deposited along the track. The sequence of a γ-ray scattering process is too fast compared with the time resolution of the detector to be measured electronically, so tracking algorithms are necessary. Gamma-ray tracking detectors are operating in position sensitive mode it means that Ge crystal are segmented in order to facilitate the localization of the gamma interactions. It is possible to improve the position resolution by using the information conveyed by the shape of the detector signal. The task of the PSA (Pulse Shape Analysis) algorithm is to analyze this signal and extract the number of interactions, the position and the energy of each interaction. PSA algorithms rely on a basis of reference signals given by single interactions and that are obtained through an experimental characterization of the detector with scanning systems. The matrix method is a new PSA algorithm that consists in fitting linearly the detector signal with a set of calculated signals. We have tested this method with both simulated and measured signals. In the case of simulated single interactions the position resolution is 1.4 mm which is within Agata's specifications. For measured signals we have obtained mean positional errors of 3.2 mm at the front end of the detector an 4.8 mm at the back end

    The atomic nucleus can adopt a very elongated shape with an axis ratio 2:1, this is the superdeformation phenomenon. Nowadays more than 300 superdeformed bands have been identified at high spin, but the determination of excitation energies, spins and parities of the associated states have been established for only one tenth of these bands. The former quantities (E{sup *}, I, {pi}) can only be determined via the linking gamma-transitions between the superdeformed (sd) and the normally deformed (nd) states. Within the framework of this thesis, we have investigated the Hg{sup 192} nucleus in order to establish E{sup *}, I and {pi}. This nucleus is predicted to be doubly magic at superdeformation and hence is taken as a reference in the mass {approx} 190 region. The experiment was carried out at Strasbourg using the Euroball-IV array and the vivitron accelerator. The obtained results are not convincing and seem to be at the limit of the performances of Euroball. Next generation of arrays will abandon the Compton-shields and use tracking concept to reconstruct the trajectories of incident photons, and therefore we expect a huge increase of efficiency. The second part of this work was focused on the research and development work for the AGATA (Advanced GAmma Tracking Array) project. We have performed simulations with the GEANT-4 code and developed tracking methods to reconstruct pair-creation events. The full AGATA will be operational around 2015 and will enhance by around two orders of magnitude the observational limits. (author)

    To review the evidence on commissioning schemes involving clinicians in the United Kingdom National Health Service, between 1991 and 2010; report on the extent and impact of clinical engagement; and distil lessons for the development of such schemes both in the UK and elsewhere. A review of published evidence. Five hundred and fourteen abstracts were obtained from structured searches and screened. Full-text papers were retrieved for UK empirical studies exploring the relationship between commissioners and providers with clinician involvement. Two hundred and eighteen published materials were reviewed. The extent of clinical engagement varied between the various schemes. Schemes allowing clinicians to act autonomously were more likely to generate significant engagement, with 'virtuous cycles' (experience of being able to make changes feeding back to encourage greater engagement) and 'vicious cycles' (failure to influence services generating disengagement) observed. Engagement of the wider general practitioner (GP) membership was an important determinant of success. Most impact was seen in GP prescribing and the establishment of services in general practices. There was little evidence of GPs engaging more widely with public health issues. Evidence for a significant impact of clinical engagement on commissioning outcomes is limited. Initial changes are likely to be small scale and to focus on services in primary care. Engagement of GP members of primary care commissioning organizations is an important determinant of progress, but generates significant transaction costs. © The Author(s) 2015.

    The Advanced Rare IsotopE Laboratory (ARIEL) is a major expansion of the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. A key part of the ARIEL project is a 10 mA 50 MeV continuous-wave superconducting radiofrequency (SRF) electron linear accelerator (e-linac). The 1.3 GHz SRF cavities are operated at 2 K. HELIAL LL helium liquefier by Air Liquide Advanced Technologies (ALAT) with a tuneable liquid helium (LHe) production was installed and commissioned in Q4’2013 [1]. It provides 4 K liquid helium to one injector and one accelerator cryomodules that were installed and tested in 2014. The 4 K to 2 K liquid helium transition is achieved on-board of each cryomodule. The cryoplant, LHe and LN2 distributions, sub-atmospheric (S/A) system and cryomodules were successfully commissioned and integrated into the e-linac cryogenic system. Required pressure regulation for both 4 K cryoplant in the Dewar and 2 K with the S/A system was achieved under simulated load. Final integration tests confirmed overall stable performance of the cryogenic system with two cryomodules installed. The paper presents details of the cryogenic system commissioning tests as well as highlights of the initial operational experience. (paper)

    The PreSPEC setup for high-resolution γ-ray spectroscopy using radioactive ion beams was employed for experimental campaigns in 2012 and 2014. The setup consisted of the state of the art Advanced GAmma Tracking Array (AGATA) and the High Energy γ deteCTOR (HECTOR+) positioned around a secondary target at the final focal plane of the GSI FRagment Separator (FRS) to perform in-beam γ-ray spectroscopy of exotic nuclei. The Lund York Cologne CAlorimeter (LYCCA) was used to identify the reaction products. In this paper we report on the trigger scheme used during the campaigns. The data-flow coupling between the Multi-Branch System (MBS) based Data AcQuisition (DAQ) used for FRS-LYCCA and the “Nouvelle Acquisition temps Réel Version 1.2 Avec Linux” (NARVAL) based acquisition system used for AGATA are also described.

    The ATLAS experiment at CERN developed an automated system for distribution of simulated and detector data. Such system, which partially consists of various ATLAS specific services, strongly relies on the WLCG infrastructure, both at the level of middleware components, service deployment and operations. Because of the complexity of the system and its highly distributed nature, a dedicated effort was put in place to deliver a reliable service for ATLAS data distribution, offering the necessary performance, high availability and accommodating the main use cases. This contribution will describe the various challenges and activities carried on in 2008 for the commissioning of the system, together with the experience distributing simulated data and detector data. The main commissioning activity was concentrated in two Combined Computing Resource Challenges, in February and May 2008, where it was demonstrated that the WLCG service and the ATLAS system could sustain the peak load of data transfer according to the computing model, for several days in a row, concurrently with other LHC experiment activities. This dedicated effort led to the consequential improvements of ATLAS and WLCG services and to daily operation activities throughout the last year. The system has been delivering to WLCG tiers many hundreds of terabytes of simulated data and, since the summer of 2008, more than two petabytes of cosmic and beam data.

    With the launching and commissioning of the Millennium ship during spring year 2000, technology and experience around podded propulsors were brought significantly forward. Millennium, a cruise liner built at Chantiers de l'Atlantique for Celebrity Cruises, is equipped with the most powerful podded propulsors ever built, the 19.5 MW Kamewal Alstom Mermaids, and is also the fastest pod propelled ship so far. This paper describes some experience from sea trials and ship operation. Results from full scale measurements and observations, ranging from cavitation performance to hydro acoustic noise, are discussed and compared to model scale results and predictions. The importance of model scale hydrodynamic testing, in combination with full scale observations, is emphasized as instrumental for a further development of podded propulsors towards naval applications.

    The Cryogenic Underground Observatory for Rare Events (CUORE) is a 1-ton scale bolometric experiment. The CUORE detector is an array of 988 TeO crystals arranged in a cylindrical, compact, and granular structure of 19 towers. These detectors will need a base temperature lower than 10 mK in order to meet the performance specifications. To cool the CUORE detector, a large cryogen free cryostat with five pulse tubes and one custom designed high power dilution refrigerator has been designed. The three vessels that form the outer shell of the CUORE cryostat were produced in 2012 and are now assembled in the Gran Sasso National Laboratories (LNGS). We report here the detailed description of the 4 K outer cryostat for the CUORE experiment together with the results of the validation tests done at the production site in 2012 and of the first commissioning to 4 K at LNGS in 2013.

    2012-01-01

    Spectroscopy of exotic nuclei has allowed numerous discoveries in nuclear structure: the shell structure changes and the magic numbers are not persistent when moving toward the drip lines. The study of exotic nuclei requires experimental spectroscopic data which give information on the deformation and the nature of excited states of the studied nucleus. Around 68 Ni, which presents signs of shell closure at N=40 (high excitation energy of the 2 + 1 and low B(E2; 2 + →0 + ) exotic nuclei, like Cr, Fe, Zn and Ge, present deformation and recent experiments point to a rapid development of collectivity. The experiment done at LNL (Laboratori Nazionali di Legnaro) on 70,72,74 Zn isotopes concluded a surprisingly long life time for the 4 + states of 74 Zn, leading to a ratio of B(E2; 4 + → 2 + ) to B(E2; 2 + → 0 + ) very low, not explained by calculations beyond mean field or shell models. This experiment was one of the first with the AGATA demonstrator. Two types of direct reactions are used to extract spectroscopic factors: knockout and low energy transfer reactions. The experimental values are not consistent between the two case s for the removal of one deeply bound nucleon in the nuclei. This difference could come from an incorrect modeling of the reaction mechanism of knockout reactions. Calculations based on intra-nuclear cascade followed by an evaporation phase show weaknesses in the sudden approximation. (author) [fr

  8. Experience with the use of ''Macintrotte'' for commissioning process equipment of the LEP Pre-injector

    International Nuclear Information System (INIS)

    1987-01-01

    ''Macintrotte'' is a CAMAC control system which is composed of a Macintosh computer and a dedicated software package. The purpose of this system is to be a versatile and user-friendly tool in the field of equipment commissioning or local interaction. The CERN interpreter Nodal has been implemented as the programming language and integrated into the Macintosh environment. The primary function of Macintrotte is to provide a stand-alone CAMAC control system with a high-level user interface for programmers and end users. In this kind of application, a CERN-made CAMAC interface is used. This has been the main use of the system during the early phase of the LPI commissioning. A secondary function of Macintrotte is to act as a front-end computer for the SMACC, a 68000-based auxiliary crate controller used in the PS central control network. In this configuration, the Macintosh is connected as a terminal to the SMACC to provide local access, basic input/output and autonomous computational facilities. This is currently used for LPI equipment which is interfaced with the main control system. A third function of the system is to interconnect, in a LAN (local area network), SMACCs and Macintoshes in order to provide high-level local control facilities for machine development and to extend the functionality of the main consoles. This is still experimental and has not yet been used in operation. This paper gives an overview of the system and describes its use for the commissioning of the LPI equipment and the experience the authors gained from this application

    In 1989, after only four and a half years of construction, the second unit of the Neckar Joint Nuclear Power Station (GKN-II) was commissioned as the third convoy type nuclear power plant. Its gross power of 1314 MWe makes the pressurized water reactor of GKN-II a unit in the highest power category so far of Siemens/KWU. Delivery to the operators ahead of schedule and observance of the budget are conclusive proof of the advantages of the convoy principle. In addition, GKN-II was able to benefit from the experience accumulated in the construction and commissioning of the two earlier convoy plants. This was reflected in the speedy completion, without major disturbances, of the warranty tests and the trial period of operation. It also has an impact on power operation, the first cycle of which showed the plant to have an availability of 100% throughout and is considered to be a full success by the operators. A special feature of GKN-II is the hybrid cooling tower ensuring that no heated cooling water is returned from the plant into the Neckar river. (orig.) [de

    We have investigated the ability of AGATA triple clusters to measure the linear polarization of gamma rays, exploiting the azimuthal-angle dependence of the Compton scattering differential cross section. To this aim, partially polarized gamma rays have been produced by Coulomb excitation of the first excited state of {sup 104}Pd and {sup 108}Pd, which decay to the ground state by emission of gamma rays of 555.8 keV and 433.9 keV, respectively. Pulse-shape analysis and gamma-ray tracking techniques have been used to determine the position and time sequence of the interaction points inside the germanium crystals. Anisotropies in the detection efficiency have been taken into account using 661.6 keV gammas from a {sup 137}Cs radioactive source. We obtain an average analyzing power of 0.451(34) at 433.9 keV and 0.484(24) at 555.8 keV. (orig.)

    The Radiation and Air Activity Monitoring System (RAAMS) at Fast Breeder Test Reactor (FBTR) is meant to monitor and record the radiation and air activity levels at various potentially active areas in FBTR complex. Health Physics Group, FBTR was associated during commissioning of RAAMS in fixing the alarm settings for the monitors, their relocation and in formulating the surveillance procedures. The areas were surveyed to check for any release of activity for confirming the observed readings during operation of the reactor. In such cases, augmentation of shielding was recommended and was promptly implemented by the station management. The details of the long and fruitful experience gained by the Health Physics Group, FBTR are described in this paper. (author)

    AUTHOR|(INSPIRE)INSPIRE-00439451; Dobos, Daniel; Rembser, Christoph

    Todays research in particle physics offers a wide field of opportunities for scientists from a variety of different subjects. Discoveries can only be made, with hundreds up to thousands of people working together in collaborations. Designing high precision detectors that can be up to several stories tall, followed by production, construction, commissioning and successful operation is only achievable with the combined effort of skilled and experienced detector physicists and engineers, while the vast amount of data recorded with those detectors calls for specialists in data analysis which are able to find the needle in a haystack or in other words the higgs in a sea of underground events. One of the biggest science collaborations worldwide is the ATLAS collaboration with more than 5000 members from around 180 institutes. ATLAS is one of four big particle physics experiments at the LHC. Its tracking system has been upgraded with a new innermost layer, referred to as Insertable B-Layer (IBL), in 2014. This thesi...

    The NOνA experiment is a long baseline neutrino experiment designed to make precision measurements of the oscillation probabilities for ν{sub µ} → ν{sub e} and ν{sub µ} → ν{sub µ} for both neutrinos and anti-neutrinos. These measurements will provide new information on the neutrino mass hierarchy, improve our knowledge of whether θ{sub 23} is non-maximal and possibility provide information on the CP violating phase δ{sub CP} of the PMNS neutrino mixing matrix. We present the observations of the first neutrino event in the NOνA far and near detectors along with data obtained during the first year of detector commissioning and operations. We use the data to demonstrate the detector’s ability to identify electron and muon neutrino events and to reject cosmic ray induced backgrounds at a level of 4 × 10{sup 7}:1. New estimates for the signal and background sensitivities of the NOνA experiment during the first year of full detector running are presented.

    Female professional contributions in nuclear science and technology are no longer a novelty. Names such as Marie Curie, Chen Shiung Wu and Rosalyn Yalow are evidence of the incessant, worldwide efforts of women to take part in fields largely reserved for men. Although society has witnessed high level female achievements as early as in the 1800s, female scientists and technicians still face a long journey ahead in empowering themselves into full and equal participation in these areas. Today, the Laboratory of Poços de Caldas of the Brazilian Commission for Nuclear Energy (CNEN/LAPOC) experiences a process of women empowerment at all levels of the institution. At the Technical Section, two of the seven research departments are headed by female researchers who play essential roles in the institution’s quest for excellence. Today, their work include coordination of a major environmental research project involving most researchers at LAPOC, successful participations on international intercomparisons of radiometric analysis and development of new methodologies in nuclear field applications. At the administrative level, female collaborators lead the Administration Section, improving several aspects of internal management, promoting further interaction at the workplace and strengthening cooperation among all departments. Regarding the capacitation level, the Commission has a long tradition of welcoming students and junior researchers through institutional programmes of training and collaboration in several projects. Today CNEN/LAPOC works with twenty scholarship grantees — half of which are women. Not only the Laboratory has reached equality in participation, but unarguably the female participants have demonstrated the most remarkable achievements among the group, attested by their continuous academic pursuit through Master’s and Doctoral degrees, full collaboration in scientific publishing and attendance in training programmes at international level.

    The ALICE experiment at the CERN LHC will study the properties of matter at the extreme temperature and energy density conditions produced in heavy ion collisions. The impact parameter of the collision will be estimated by means of the Zero Degree Calorimeters (ZDC), that measure the energy carried away by the non-interacting (spectator) nucleons. All the spectator nucleons have the same energy, therefore the calorimeter response is proportional to their number, providing a direct information on the centrality of the collision. Two identical sets of hadronic calorimeters are located at opposite sides with respect to the interaction point, 116 m away from it, where the two LHC beams circulate in two different pipes. Each set of detectors consists of a neutron (ZN) calorimeter, placed between the two beam pipes and a proton (ZP) calorimeter, positioned externally to the outgoing beam pipe. The ZDC are spaghetti calorimeters, which detect the Cherenkov light produced by the charged particles of the shower in the quartz fibers, acting as the active material embedded in a dense absorber matrix. In summer 2007 the ZN and ZP calorimeters have been placed on a movable platform and then installed in the LHC tunnel. The results of the commissioning studies are shown. The monitoring systems adopted to control the stability of the PMT responses, i.e. light injection with a laser diode and cosmic rays, are described in detail. The foreseen calibration with e.m. dissociation events in Pb-Pb collisions will also be discussed. Finally the first measurements carried out during the commissioning in the LHC tunnel will be presented.

    1979-01-01

    From among the nuclear facilities constructed in France the authors cite eight large reactors, ranging from critical assemblies to power reactors, that have been finally shut-down since 1965. A brief account is given of the way in which the various operations were carried out after the final control rod drop, a distinction being drawn between the shut-down proper and the containment and dismantling work. A description is also given, from the technical and regulatory standpoint, of the final stage attained, and mention is made of French safety arrangements and of the part played by the safety services during decommissioning operations. Among the lessons derived from French experience, the authors mention the completion of operations without any serious safety problems, and with guarantees for the protection of personnel and the population as a whole, by conventional techniques; the advantage of planning decommissioning operations from the very beginning of construction of the facilities; and the importance of filing descriptive documents. In view of the experience gained, the French Atomic Energy Commission has devised internal procedures for facilitating the application of regulations governing the shut-down and decommissioning phases, which are aimed at preserving surveillance procedures similar to those in force during normal operation.

    As the first Canadian users of the Velocity™ program offered by Siemens, we would like to share our experience with the program. The Velocity program involves the measurement of the commissioning data by an independent Physics consulting company at the factory test cell. The data collected was used to model the treatment beams in our planning system in parallel with the linac delivery and installation. Beam models and a complete data book were generated for two photon energies including Virtual Wedge, physical wedge, and IMRT, and 6 electron energies at 100 and 110 cm SSD. Our final beam models are essentially the Velocity models with some minor modifications to customize the fit to our liking. Our experience with the Velocity program was very positive; the data collection was professional and efficient. It allowed us to proceed with confidence in our beam data and modeling and to spend more time on other aspects of opening a new clinic. With the assistance of the program we were able to open a three-linac clinic with Image-Guided IMRT within 4.5 months of machine delivery. © 2008 American Association of Physicists in Medicine.

    The COMPASS-II experiment is a fixed target experiment situated at CERN. A tertiary myon beam from the SPS scattered of protons from a liquid hydrogen target is used to measure Deeply Virtual Compton Scattering (DVCS) and Hard Exclusive Meson Production (HEMP). These processes offer a unique way to determine Generalized Parton Distributions, which are related to the total angular momentum of quarks, antiquarks and gluons in the nucleon by Ji's Sum Rule. One of the major parts of the COMPASS-II upgrade is the CAMERA detector. CAMERA is a proton recoil detector surrounding the COMPASS-II liquid hydrogen target. Its purpose is to measure the recoiled target proton in DVCS and HEMP reactions and viz to act as a veto to ensure the exclusivity of the measurement. The talk gives an outline of the detector and its readout electronics. It is focused on the commissioning and performance of the CAMERA detector and gives a brief insight into the ongoing DVCS analysis.

    The occupational injury and fatality experience during 32 years of the development of the atomic energy industry under the direction of the Atomic Energy Commission (AEC) and its predecessor, the Manhattan Engineering District, is reviewed. Data are included on the cause of all accidents, including fires and transportation accidents, and the cost of AEC property damage. Fatalities of AEC and contractor personnel from all causes during the 32-year period totaled 321, of which 184 occurred in construction; 121 in AEC operations such as production, research, and services; and 16 in Government functions. There were 19,225 lost-time injuries attributable to all accidental causes, or a 32-year frequency rate of 2.75 based on the number of injuries per million man-hours. There were six deaths attributable to nuclear causes, thee of which were due to blast and flying missiles and three caused by whole-body radiation exposure. Forty-one workers were involved in lost-time radiation accidents, of whom 26 showed clinical manifestations attributable to radiation, resulting in permanent partial-disability of three workers and the loss of a digit by four workers, while the others did not develop evidence of radiation injury

    Full Text Available The SwissFEL Injector Test Facility operated at the Paul Scherrer Institute between 2010 and 2014, serving as a pilot plant and test bed for the development and realization of SwissFEL, the x-ray Free-Electron Laser facility under construction at the same institute. The test facility consisted of a laser-driven rf electron gun followed by an S-band booster linac, a magnetic bunch compression chicane and a diagnostic section including a transverse deflecting rf cavity. It delivered electron bunches of up to 200 pC charge and up to 250 MeV beam energy at a repetition rate of 10 Hz. The measurements performed at the test facility not only demonstrated the beam parameters required to drive the first stage of an FEL facility, but also led to significant advances in instrumentation technologies, beam characterization methods and the generation, transport and compression of ultralow-emittance beams. We give a comprehensive overview of the commissioning experience of the principal subsystems and the beam physics measurements performed during the operation of the test facility, including the results of the test of an in-vacuum undulator prototype generating radiation in the vacuum ultraviolet and optical range.

    Experimental Hall D, with flagship experiment GlueX, was constructed as part of the 12 GeV CEBAF upgrade. A new magnetically extracted electron beam line was installed to support this hall. Bremsstrahlung photons from retractable radiators are delivered to the experiment through a series of collimators following a long drift to allow for beam convergence. Coherent Bremsstrahlung generated by interaction with a diamond radiator will achieve a nominal 40% linear polarization and photon energies between 8.5 and 9 GeV from 12.1 GeV electrons, which are then tagged or diverted to a medium power 60kW electron dump. The expected photon flux is 107-108 Hz. This paper discusses the experimental line design, commissioning experience gained since first beam in spring 2014, and the present results of beam commissioning by the experiment.

With the introduction of the new Danish DS 3090 standard, "The commissioning process in buildings...... on ethnographic methods and theories, this paper will analyse and discuss what the use of a commissioning adviser in the design stage means for the interaction between design and operation. It may seem that "technical solutions" are made before “ongoing learning processes” in which new themes are articulated...

    The National Spherical Torus Experiment Upgrade (NSTX-U) will advance the physics basis required for achieving steady-state, high-beta, and high-confinement conditions in a tokamak by accessing high toroidal fields (1 T) and plasma currents (1.0-2.0 MA) in a low aspect ratio geometry (A  =  1.6-1.8) with flexible auxiliary heating systems (12 MW NBI, 6 MW HHFW). This paper describes the progress in the development of L- and H-mode discharge scenarios and the commissioning of operational tools in the first ten weeks of operation that enable the scientific mission of NSTX-U. Vacuum field calculations completed prior to operations supported the rapid development and optimization of inductive breakdown at different values of ohmic solenoid current. The toroidal magnetic field (B T0  =  0.65 T) exceeded the maximum values achieved on NSTX and novel long-pulse L-mode discharges with regular sawtooth activity exceeded the longest pulses produced on NSTX (t pulse  >  1.8 s). The increased flux of the central solenoid facilitated the development of stationary L-mode discharges over a range of density and plasma current (I p). H-mode discharges achieved similar levels of stored energy, confinement (H98y,2  >  1) and stability (β N/β N-nowall  >  1) compared to NSTX discharges for I p  ⩽  1 MA. High-performance H-mode scenarios require an L-H transition early in the I p ramp-up phase in order to obtain low internal inductance (l i) throughout the discharge, which is conducive to maintaining vertical stability at high elongation (κ  >  2.2) and achieving long periods of MHD quiescent operations. The rapid progress in developing L- and H-mode scenarios in support of the scientific program was enabled by advances in real-time plasma control, efficient error field identification and correction, effective conditioning of the graphite wall and excellent diagnostic availability.

    2010-01-01

    The 2006 Act on 'Open Access to Information and Nuclear Safety' provides free access to nuclear installations data and submits nuclear facilities to an independent administrative authority, the ASN (French Nuclear Safety Authority). A local information committee (CLI - Commission locale d'informations) has been set up for each nuclear facility. It includes all the parties involved and may commission expert studies and environmental measurement tests from independent laboratories. Prompted by environmental organizations, the Cadarache CLI commissioned a CRIIRAD (Commission de Recherche et d'Informations Independantes sur la Radioactivite) fact-finding survey in 2008-2009 to evaluate the environmental impact of the CEA/Cadarache installations since they were created. This study points to a moderate present impact, though a lack of data makes it impossible to reconstruct environmental impact prior to 1979. A set of guidelines are put forward to assess the past impact in greater detail and to lessen the current impact even further. Following this study, additional steps to minimize this impact will be taken by CEA/Cadarache inside the facilities, and by the relevant LCI outside the installations. Developing independent expert skills is a major challenge for CLIs to gain better knowledge of nuclear activities and improve their local management. (author)

    Full Text Available In this paper the results of a detailed seismic microzonation, performed at Sant’Agata Fossili (Piemonte region, northern Italy are presented. We study the local seismic response of this small village using a level 3, that is the most accurate level following the Italian code of seismic microzonation. The activity steps consist in a gradual widening of knowledge of the different aspects of the amplification phenomena. A multidisciplinary approach has been performed to obtain the local seismic response: including a study of local geology, geophysical and geotechnical characterization of the lithologies, and numerical and experimental analyses. We finally compare the obtained elastic response spectra to the prescribed spectra of the Italian Building Code (in Italian: Norme Tecniche per le Costruzioni. Our results show the geologic and geophysical differences of the subsoil, that produce different local seismic response in terms of amplification factors and acceleration response spectra.

    and visualize the historical building in its context. These modern techniques of survey, based on the creation of point clouds, are now widely used both in the study of a building and for the thorough description of architectural details and decorations. This paper aims at describing the methodological approach and the results of the 3D survey of the Chapel of St. Agata in Pisa, aimed at its restoration. For the development of a restoration project, the survey drawings must represent not only the geometry of a building, but also the materials and the level of degradation. So, we chose to use both the laser scanner - which guarantees uniformity of the geometric survey precision - and a 3D image-based modelling. The combined use of these two techniques, supported by a total station survey, has produced two point clouds in the same reference system, and allowed the determination of the external orientation parameters of the photographic images. Since these parameters are known, it was possible to texturize the laser scanner model with high quality images. The adopted methodology, as expected, gave back metrically correct and graphically high-quality drawings. The level of detail of the survey, and consequently of the final drawings, has been previously defined for the identification of all the elements required for the analysis of the current state, such as the clear identification and position of all the degradation phenomena, materials and decorative elements such as some fragmented and heavily damaged frescoes.

    Design approach of high voltage generator for 750 keV DC accelerator, developed at RRCAT Indore, inculcates a unique feature of high frequency operation of symmetrical Cockcroft-Walton voltage generator. Apart from design simplicity and feasibility of modular construction, the high frequency use of symmetrical Cockcroft-Walton circuit gives added advantages of less ripple, better regulation, faster response and low stored energy in the system. Additionally the scheme allows us the use of low voltage, light weight components thus improving the overall economy of the system. The accelerator has been commissioned and made operational at its rated energy of 750 keV in the recent past. With brief introduction on design aspects of high voltage generator and filament power supply of this accelerator, the paper presented here describes the developmental steps of various components with focus on challenges encountered and solutions implemented. Development of high frequency inverter, high voltage ferrite core transformer, compensating inductors, interface bushings, voltage multiplier stack, and filament transformer along with floating power supply for electron emitter of the accelerator has been dealt in detail. The failures encountered during commissioning stages of the accelerator have been reported with measures taken for improvement of the specific components. Intricacies of the reflected capacitance of the multiplier stack and arc-current ground return are also described with their effects on system operation and reliability. (author)

    The Standard Model of particle physics predicts the existence of the Higgs boson, which preferentially decays to b quark pairs at low mass. The identification of jets stemming from such quarks in the ATLAS detector, placed at the LHC, is thus one of the keys to modern particle physics. In this document, an overview of the b-tagging methods used in ATLAS as well as the optimization of a specific algorithm, JetProb, are presented. The preparation to the measurement of these algorithms efficiency in data is also developed. Finally, after the first data taking at 900 GeV and then at the record energy of 7 TeV in 2009-2010, the first results on charged track studies and b-tagging commissioning were obtained and are gathered together here. Comparison with simulation shows a good agreement and the first b-jet and top events candidates are studied. (author)

  20. Large scale commissioning and operational experience with tier-2 to tier-2 data transfer links in CMS

    Letts, J; Magini, N

    2011-01-01

    Tier-2 to Tier-2 data transfers have been identified as a necessary extension of the CMS computing model. The Debugging Data Transfers (DDT) Task Force in CMS was charged with commissioning Tier-2 to Tier-2 PhEDEx transfer links beginning in late 2009, originally to serve the needs of physics analysis groups for the transfer of their results between the storage elements of the Tier-2 sites associated with the groups. PhEDEx is the data transfer middleware of the CMS experiment. For analysis jobs using CRAB, the CMS Remote Analysis Builder, the challenges of remote stage out of job output at the end of the analysis jobs led to the introduction of a local fallback stage out, and will eventually require the asynchronous transfer of user data over essentially all of the Tier-2 to Tier-2 network using the same PhEDEx infrastructure. In addition, direct file sharing of physics and Monte Carlo simulated data between Tier-2 sites can relieve the operational load of the Tier-1 sites in the original CMS Computing Model, and already represents an important component of CMS PhEDEx data transfer volume. The experience, challenges and methods used to debug and commission the thousands of data transfers links between CMS Tier-2 sites world-wide are explained and summarized. The resulting operational experience with Tier-2 to Tier-2 transfers is also presented.

  1. Radiation protection experience during active commissioning of the Thorp reprocessing plant

    1996-01-01

    BNFL's Thermal Oxide Reprocessing Plant (Thorp) reprocesses uranium oxide fuel assemblies which have been irradiated in thermal reactors in the UK and overseas. Plans for the plant were first announced in 1974. Application for planning permission was submitted in 1977, and government permission to construct the plant was granted after the Windscale inquiry in 1977. The plant was given the license to start active commissioning in head end in early 1994, and then in chemical plants in late 1994. Presently the whole of the process is being challenged in a planned commissioning strategy which will last into 1996. Thorp is designed to reprocess the spent oxide fuel into uranium trioxide (UO 3 ) and plutonium dioxide (PuO 2 ). The Thorp complex can be essentially broken down into three distinct areas: Thorp receipt and storage provides pond storage for fuel awaiting reprocessing in Thorp. Head end fuel is transferred from receipt and storage into the feed pond where it is monitored to check fissile content, burn up and cooling time. The individual fuel assemblies for LWR fuel, or cans in the case of AGR fuel, are transferred onto the shear elevator and carried up to the shear cave. The fuel is sheared into small lengths to optimize the dissolution of the fuel inside the cladding. The sheared fuel and cladding debris is directed via a chute into one of three dissolvers, each with a nominal 1.8 teU capacity and dissolved in 8M nitric acid for approximately 16 hours. The cladding hulls are retained in a removable basket and sent for encapsulation. Insoluble fission products and fine particles of cladding are removed by centrifugation. Clarified dissolver solution is then accounted for by measurements taken for volume, mass and isotopic composition. Following this, the solution is transferred to buffer storage tarns and fed onto the chemical separation area. The liquor is transferred to the chemical separation area where it undergoes first cycle separation in pulsed columns

    ASDEX Upgrade was equipped with a distributed real-time (RT) control and diagnostic system. Application processes can be freely mapped onto controllers. They communicate through RT data exchanged via a shared memory network. Processes run self-organized with a data-driven scheme, i.e. a process executes when all required data has become available and produced data drive other processes waiting for these. The process chain starts periodically through a time-synchronous cycle master process to deterministically execute closed-loop control. Generic processes were implemented for feedback of plasma position and shape, and for performance control with fuelling and heating systems, for evaluation and monitoring of plasma quantities and Tokamak components, and generation of reference values in RT. Upon commissioning the system was speed-optimized to run a 1.6 ms cycle. Methods to exchange data and time information in RT and operate distributed data-driven processes work efficiently and reliably. The ability to freely map processes to computing nodes and RT data to generic processes provides outstanding configurational flexibility for optimizing system performance or supporting in situ replay and simulation runs. In the computation of reference values in RT acting on underlying feedback controllers, demonstrated for soft-landing, we see great potential to counteract instabilities or optimize pulses

    Liu, Chang

    In this thesis, the first physics measurements using the Compact Muon Solenoid (CMS) at the Large Hadron Collider (LHC) are presented. These physics measurements were performed using cosmic ray muons traversing the CMS detector. The CMS detector is optimized for the detection of muons and the results presented here also have a purpose of helping in the commissioning of the detector for the LHC collisions. Two analyses were conducted; the first is a measurement of the charge ratio of positive to negative muons, and the second is a measurement of the differential and absolute flux of incident cosmic rays. The charge ratio measurement was made using both the muon and tracking detectors and is highlighted by its data-driven method. The charge ratio over the momentum range starting from 10 GeV were measured at the detector center and then transferred to the earth's surface. The flux measurement was performed using the muon system only. The flux was measured over the momentum range from 15 GeV to over 1 TeV at the...

    The helium refrigerator/liquefier (R/L) for the Steady State Super conducting Tokamak (SST-1) has been developed with very stringent specifications for the different operational modes. The total refrigeration capacity is 650 W at 4.5 K and liquefaction capacity of 200 l/h. A cold circulation pump is used for the forced flow cooling of 300 g/s supercritical helium (SHe) for the magnet system (SCMS). The R/L has been designed also to absorb a 200 W transient heat load of the SCMS. The plant consists of a compressor station, oil removal system, on-line purifier, Main Control Dewar (MCD) with associated heat exchangers, cold circulation pump and warm gas management system. An Integrated Flow Control and Distribution System (IFDCS) has been designed, fabricated and installed for distribution of SHe in the toroidal and poloidal field coils as well as liquid helium for cooling of 10 pairs of current leads. A SCADA based control system has been designed using PLC for R/L as well as IFDCS. The R/L has been commissioned and required parameters were achieved confirming to the process. All the test results and commissioning experiences are discussed in this paper.

    Three cryomodules have been designed and built as intermediate prototypes for the CEBAF 12 GeV upgrade. This paper will discuss the commissioning and operational experience with the second of these cryomodules, which was installed and commissioned in the Jefferson Lab 10 kW Free Electron Laser Facility. Within the cryomodule are eight 7-cell, 1497 MHz cavities. It was designed to accelerate 1 mA of beam in excess of 70 MV and to have the same footprint as a standard CEBAF cryomodule. The cryomodule was installed in parallel with the FEL beam line in the spring of 2004 and characterized simultaneous with beam delivery. It was installed in the beam line in the early summer of 2004 and has since been operated as part of an energy recovered linac with 5 mA of beam current and 75 MV accelerating gradient for extended periods of time. Additionally, it was operated at 1 mA of beam current and 80 MV of accelerating gradient for several hours without a trip. In the latter operating mode the beam current was limited by the injector setup

    A neglected area of research within criminality has been that of the experience of the offence for the offender. The present study investigates the emotions and narrative roles that are experienced by an offender while committing a broad range of crimes and proposes a model of criminal narrative experience (CNE). Hypotheses were derived from the circumplex of emotions, Frye, narrative theory, and its link with investigative psychology. The analysis was based on 120 cases. Convicted for a variety of crimes, incarcerated criminals were interviewed and the data were subjected to smallest space analysis (SSA). Four themes of CNE were identified: Elated Hero, Calm Professional, Distressed Revenger, and Depressed Victim in line with the recent theoretical framework posited for narrative offence roles. The theoretical implications for understanding crime on the basis of the CNE as well as practical implications are discussed.

    Before the upgraded vertex detector for the Belle II experiment at the SuperKEKB collider in Japan will be installed, a dedicated detector system for machine commissioning (BEAST II) will be employed. One of its main objectives is to measure and characterize the different background types in order to ensure a safe environment before the installation of the actual silicon detector systems close to the interaction point. FANGS, a detector system at BEAST II, based on ATLAS-IBL front-end electronics and planar silicon sensors is currently being developed for this purpose. The unique feature of this detector system is the high energy resolution achieved by using an external FPGA clock to sample the time-over-threshold signal, while keeping the excellent timing properties. The complete detector system is presented in this talk.

    The basis of the G 0 experiment is a parity-violating process giving access to the strange form factors of the proton. It requires the measurement of a set of asymmetries, in elastic electron scattering from hydrogen and quasi-elastic scattering from deuterium, at different Q 2 and at different angles. The experimental site is the Thomas Jefferson National Accelerator Facility (J Lab.), Newport News, VA (USA). The formalism that connects asymmetries with the proton properties at the quark level, the experimental set-up and the present status are described. A section is devoted to a special electronic module, built at the IPN-Orsay, using Digital Signal Processors (DSPs)

In this thesis we present work done on both the simulation of the ATLAS physics potential for a charged Higgs boson and the construction of the Semiconductor Tracker (SCT) - a subdetector within the ATLAS Inner Detector. The discovery of a charged Higgs boson would be an unambiguous sign of physics beyond the Standard Model (SM) and it is thus of great interest to study the ATLAS potential for a charged Higgs discovery. Two such studies have been conducted for this thesis. In the first study a large-mass-splitting Minimal Supersymmetric Standard Model (MSSM) is assumed in which the charged Higgs boson decays into a W boson and a neutral Higgs may receive a large branching ratio.We conclude, however, that charged Higgs searches in this decay channel are made difficult by a large irreducible SM ba...

  13. An Innovative Beam Halo Monitor system for the CMS experiment at the LHC: Design, Commissioning and First Beam Results

    CERN Document Server

    AUTHOR|(INSPIRE)INSPIRE-00344917; Dabrowski, Anne

    The Compact Muon Solenoid (CMS) is a multi-purpose experiment situated at the Large Hadron Collider (LHC). The CMS has the mandate of searching new physics and making precise measurements of the already known mechanisms by using data produced by collisions of high-energy particles. To ensure high quality physics data taking, it is important to monitor and ensure the quality of the colliding particle beams. This thesis presents the research and design, the integration and the first commissioning results of a novel Beam Halo Monitor (BHM) that was designed and built for the CMS experiment. The BHM provides an online, bunch-by-bunch measurement of background particles created by interactions of the proton beam with residual gas molecules in the vacuum chamber or with collimator material upstream of the CMS, separately for each beam. The system consists of two arrays of twenty direction-sensitive detectors that are distributed azimuthally around the outer forward shielding of the CMS experiment. Each detector is ...

  15. Large Scale Commissioning and Operational Experience with Tier-2 to Tier-2 Data Transfer Links in CMS

    CERN Document Server

    Letts, James

    2010-01-01

    Tier-2 to Tier-2 data transfers have been identified as a necessary extension of the CMS computing model. The Debugging Data Transfers (DDT) Task Force in CMS was charged with commissioning Tier-2 to Tier-2 PhEDEx transfer links beginning in late 2009, originally to serve the needs of physics analysis groups for the transfer of their results between the storage elements of the Tier-2 sites associated with the groups. PhEDEx is the data transfer middleware of the CMS experiment. For analysis jobs using CRAB, the CMS Remote Analysis Builder, the challenges of remote stage out of job output at the end of the analysis jobs led to the introduction of a local fallback stage out, and will eventually require the asynchronous transfer of user data over essentially all of the Tier-2 to Tier-2 network using the same PhEDEx infrastructure. In addition, direct file sharing of physics and Monte Carlo simulated data between Tier-2 sites can relieve the operational load of the Tier-1 sites in the original CMS Computing Model...

  16. Laserscanning e 3D Modelling nell’archeologia urbana: lo scavo della chiesa di Sant’Agata al Carcere a Catania (Italia

    Full Text Available Urban archaeology undoubtedly represents the most problematic branch of archaeological research, due to the many problems of conservation and promotion of the evidence. A significant example is presented by the excavations carried out by the Superintendency for Cultural Goods of Catania in the church of “Sant’Agata al Carcere”, located in the heart of down town Catania. The most important discovery of the archaeological campaign was part of a ruined archaic wall in polygonal technique, located in the western side of the sacristy of the “Sant’Agata al Carcere” church. Furthermore, a late hellenistic votive deposit located within a pit, contained two small jars and a lidded stamnos, was discovered between the stones of the fallen wall. The excavations were performed during the restoration of the church. After the restoration, due to the special function of the building, it was necessary to quickly re-open the churches, thereby hiding the archaeological monuments from public view. In this perspective, a virtual museum project was implemented by an equipe of archaeologists and information technologists of the Archeomatica Project of Catania University, in order to display the important discoveries from the sacristy, which were covered up by the re-location of the floor in situ, applying both laser-scanner and 3D modelling techniques.

  20. The Lhc beam commissioning

    International Nuclear Information System (INIS)

    Redarelli, S.; Bailey, R.

    2008-01-01

    The plans for the Lhc proton beam commissioning are presented. A staged commissioning approach is proposed to satisfy the request of the Lhc experiments while minimizing the machine complexity in early commissioning phases. Machine protection and collimation aspects will be tackled progressively as the performance will be pushed to higher beam intensities. The key parameters are the number of bunches, k b , the proton intensity pe bunch, N, and the β in the various interaction points. All together these parameters determine the total beam power and the complexity of the machine. We will present the proposed trade off between the evolution of these parameters and the Lhc luminosity performance.

    The upgrade of the ATLAS experiment at LHC foresees the insertion of an innermost silicon layer, called Insertable B-layer (IBL). IBL read-out system will be equipped with new electronics. The Readout-Driver card (ROD) is a VME board devoted to data processing, configuration and control. A pre-production batch has been delivered in order to perform tests with instrumented slices of the overall acquisition chain, aiming to finalize strategies for system commissioning. In this contribution both setups and results will be described, as well as preliminary studies on changes in order to adopt the ROD for the ATLAS Pixel Layers 1 and 2.

  2. Evolution of new X and Y positioning system for 540 MWe PHWR fuelling machines - based on commissioning experience

    In PHWR units, X and Y positioning system is provided to give feedback regarding the misalignment between end-fitting and Fuelling Machine (FM) Head during homing on process for carrying out the correction before clamping the Head. The existing design of X and Y Positioning System works by measuring the misalignment by sensing the tilt of the FM Head in X and Y direction caused by its mechanical interfacing with end-fitting as it is advanced in Z direction. The misalignment of Head is corrected by moving it in X and Y direction by X-fine and Y-fine drives, at Z pre-stop position. This correction is vital for achieving the satisfactory sealing of heavy water from channel at snout of FM Head with end fitting. During testing and commissioning trials, it was found that the end fitting of 540 MWe coolant channel assembly either tilts or bends due to the application of load by Fuelling Machines during the process of homing-on of FM Head. Due to this phenomenon, value of misalignment sensed by the Positioning System was considerably lower than the actual misalignment and consequently results in uncorrected misalignment. It was also observed that the high unbalanced moments caused by movement of heavier mass of B-ram in FM Head was further aggravating the misalignment problem. The problem, as an interim measure, was solved by optimising the loads acting on the end fitting to achieve the practically minimum possible uncorrected misalignment. However, to provide a lasting solution for this problem, a new X and Y Positioning System has been evolved. In this system, the misalignment between FM Head and end fitting is found by direct actuation of linear Variable Differential Transformer (LVDT) sensors by four separate alignment plates mounted on the snout. Further development to evolve a completely non-invasive technique using laser sensors has also been undertaken. This paper describes the problems encountered during commissioning of existing design of X and Y Positioning

    Highlights: • Technical scale, tritium compatible liquid phase catalytic exchange (LPCE). • Technical scale, tritium compatible cryogenic distillation. • Combines processing option for tritiated water and isotope separation. -- Abstract: The European union in kind supply for the ITER fuel cycle development consists, among others, of the water detritiation system (WDS) and the isotope separation system (ISS). In order to mitigate the release of tritium to the environment, these systems are combined by feeding hydrogen exhaust from the ISS into the WDS for final processing. Therefore, the WDS is the final tritium barrier before releasing hydrogen (H{sub 2}) exhaust to the environment. The TRENTA 4 scaled prototype facility at TLK is based on combination of the combined electrolysis and catalytic exchange (CECE) process and a cryogenic distillation (CD) process. All components are fully tritium compatible and controlled using a state of the art control system for process automation, backed up by an additional dedicated safety system. The paper will give a detailed overview of the current experimental facility including all process components. Furthermore the paper will present the results of the functional test of the WDS/ISS combination using protium and deuterium, as well the results of the first commissioning runs using HTO of approximately 5 × 10{sup 9} Bq kg{sup −1} activity concentration.

    Following from similar initiatives worldwide, the U.K.'s Fisheries Science Partnership (FSP) was established in 2003 to provide the fishing industry with opportunities to propose and participate in scientific studies in collaboration with fishery scientists. Key concepts were that most of the available funding would support industry participation, that industry, not scientists, would come up with the ideas for projects, and that commercial fishing vessels and fishing methods would be used to address specific concerns of the fishing industry in a scientifically controlled manner. Nearly 100 projects had been commissioned by March 2012, covering annual time-series surveys of stocks subject to traditional assessment, and ad hoc projects on, e.g. gear selectivity, discard survival, tagging and migration and fishery development. The extent to which the results of the projects have been used by stakeholders, fishery scientists and fishery managers at a national and E.U. level is evaluated, along with the degree of industry interest and involvement, and reasons are identified for successes or failures in the uptake of the results into management and policy. Finally, the question is posed whether the programme has been successful in improving the engagement of the fishing community in the science-management process and in fostering communication and greater trust between fishers, scientists and managers. © 2013 Crown Copyright. © 2013 The Fisheries Society of the British Isles.

  6. Commissioning and experience in stripping, filtering and measuring the 4.2 MeV/u lead ion beam at CERN Linac 3

    1996-01-01

    The new CERN Heavy Ion Linac (Linac3) accelerates a Pb 27+ beam to 4.2 MeV/u. The beam is then stripped to Pb 53+ by a carbon foil, and, after stripping, a 12 m filter line prepares the beam for the injection into the Proton Synchrotron Booster (PSB). The filter line eliminates the unwanted charge states, checks the beam quality (energy, energy spread, transverse emittance and intensity), and finally transports the beam in the lines leading to the PSB. The paper summarises the transverse beam dynamics of the line, and reports on its commissioning, especially focusing on the experiments that led to the stripper choice, and on the measurements performed with a specially developed single pulse multislit emittance device. The operational experience is also reported. (author)

  7. Installation, commissioning and performance of the trigger system of the Double Chooz experiment and the analysis of hydrogen capture neutrino events

    Energy Technology Data Exchange (ETDEWEB)

    Lucht, Sebastian

    2013-11-18

    The Double Chooz experiment is a reactor antineutrino experiment located at Chooz, a small town in the Ardennes region in the north of France close to the Belgium border. The aim of the experiment is to measure the leptonic mixing angle θ{sub 13}. The antineutrino flux is measured by two identical detectors at different distances from the reactor cores used as neutrino source, in a so called ''disappearance'' experiment. Double Chooz is a precision experiment because previous experiments indicated a small value of θ{sub 13}. Therefore, the systematic uncertainties introduced by background events and detector related components have to be as small as possible. The detector and all electronic components have been designed accordingly. The first part of this thesis describes the trigger and timing system of the Double Chooz experiment. This system triggers the data acquisition of the detector. It continuously monitors the signals of the photomultiplier tubes (PMTs) of the detector. These signals are summed for groups of PMTs (group signal) and for all PMTs (sum signal). The group signals are the input signals to the trigger system. They are discriminated by one threshold resulting in a multiplicity condition on the number of active group signal discriminators. The sum signal is discriminated by four thresholds. The default trigger configuration for the Double Chooz experiment is based on a combination on the sum signal discriminators and the multiplicity condition. In addition, the trigger system provides a common clock signal for all data acquisition components and an online event classification to allow an online data reduction. The trigger system was installed and commissioned in 2011. In this thesis the commissioning of the trigger system and its performance is presented. Furthermore the development and tests of possible improvements for the trigger system are presented and discussed. The second part of this thesis introduces a complementary

    2018-01-01

    The introduction of reconfigurable manufacturing systems (RMS), Industry 4.0 and the associated technologies requires the establishment of new competencies. Towards that goal, Aalborg University (AAU) has developed an Industry 4.0 learning factory, the AAU Smart Production Lab. The AAU Smart...... Production Lab integrates a number of Industry 4.0 technologies for learning and research purposes. One of the many techniques is virtual commissioning. Virtual commissioning uses a virtual plant model and real controllers (PLCs) enabling a full emulation of the manufacturing system for verification. Virtual...... commissioning can lower the commissioning time up to 63%, allowing faster time to market. However, virtual commission is still missing industrial impact one of the reasons being lack of competencies and integration experiences. The paper presents the setup of the virtual commissioning learning platform...

    2011-01-01

    The ability to identify jets containing b-hadrons is important for the high-pT physics program of a general-purpose experiment at the LHC such as ATLAS. Two robust b-tagging algorithms taking advantage of the impact parameter of tracks or reconstructing secondary vertices have been swiftly commissioned and used for several analyses of the 2010 data: bottom and top quark production cross-section measurements, searches for supersymmetry and new physics, etc. Building on this success, several more advanced b-tagging algorithms are commissioned with the 2011 data. All these algorithms are based on a likelihood ratio formalism to compare the signal (b-jet) or background (light or in some cases charm jet) hypotheses, using Monte Carlo predicates. The accuracy with which the simulation reproduces the experimental data is therefore critical and is explained in details, as well as the expected improvement in performance brought in by these new algorithms and some first results about the measurement in data of their pe...

    The ability to identify jets containing b-hadrons is important for the high-pT physics program of a general-purpose experiment at the LHC such as ATLAS. Two robust b-tagging algorithms, JetProb and SV0, taking advantage of the impact parameter of tracks or reconstructing secondary vertices have been swiftly commissioned and used for several analyses of the 2010 data: bottom and top quark production cross-section measurements, searches for supersymmetry and new physics, etc. Building on this success, several more advanced b-tagging algorithms are commissioned using ~330 pb^{-1} of the 2011 data. All these algorithms are based on a likelihood ratio formalism to compare the signal (b-jet) or background (light or in some cases charm jet) hypotheses, using Monte Carlo predicates. The accuracy with which the simulation reproduces the experimental data is therefore critical and is explained in details, as well as the expected improvement in performance brought in by these new algorithms.

    2005-05-01

    This study has been performed in the frame of quark gluon plasma physics research in the STAR experiment at RHIC. It deals with the design, the construction and the commissioning of a barrel of silicon-strip detectors (SSD). Added to the Silicon Vertex Tracker (SVT) of the STAR detector, it extends the capabilities of track reconstruction for charged particles emitted in ultra-relativistic heavy-ion collisions. It also contributes to the general study of the quark-gluon plasma production undertaken at STAR. The SSD is a cylinder of 1 m long and of 23 cm radius, and it is composed of 320 compact identical modules. Each module includes one double-sided silicon micro-strip detector, 12 readout chips ALICE 128C, 12 TAB ribbons, 2 COSTAR control chips and 2 hybrids supporting all the components. The document explains why the SSD is an important and relevant element, and justifies the technological choices as well as their validation by in-beam characterization. All component functionalities, characteristics and test procedures are presented. The data and test results are stored in a database for tracing purpose. Component and module production is described. Two parallel studies have been performed, analysed and described. One on the temperature dependence of the module performances and the other one on the optimal adjustments of the analogue blocks inside the ALICE 128C chip. The SSD installation on the RHIC site as well as the commissioning are presented together with the first data takings. (author)

    The KATRIN experiment aims to determine the neutrino mass scale with a sensitivity of 200 meV/c{sup 2} (90% C.L.) by a precision measurement of the shape of the tritium β-spectrum in the endpoint region. The energy analysis of the decay electrons is achieved by a MAC-E filter spectrometer. To determine the transmission properties of the KATRIN main spectrometer, a mono-energetic and angular-selective electron source has been developed. In preparation for the second commissioning phase of the main spectrometer, a measurement phase was carried out at the KATRIN monitor spectrometer where the device was operated in a MAC-E filter setup for testing. The results of these measurements are compared with simulations using the particle-tracking software ''Kassiopeia'', which was developed in the KATRIN collaboration over recent years. (orig.)

  15. Waste management experience during all the life cycle of treatment facilities from commissioning till decommissioning. Today's situation and future trends

    International Nuclear Information System (INIS)

    Decobert, Guy; Devezeaux de Lavergne, Jean-Guy; Maurin, Matthieu

    2005-01-01

    Over time, the concepts of waste management have deeply evolved. In the case of the earlier generation of treatment plants, on-line conditioning was generally not implemented. In several cases, the strategy was clearly set as promoting storage of 'interim' raw waste, and implementing long-run R and D programs for future conditioning. Thus, one of the main objectives of the last generation of plants was to implement on-line conditioning of all waste, i.e. including waste issued from the used fuel and also those issued from plant operation (technological waste and effluent treatment waste). These strategic issues are naturally part of the core of the design of every new plant, as part of the operating performance. The enormous amount of experience collected from previous generations of plants, and managed by AREVA, allows us to go one step further. Indeed, our target is to rely on a comprehensive vision of waste management best practices, from the plant design through its decommissioning. This will allow AREVA to think about the next plant generation when encompassing the whole life cycle of the plant, including its different steps: Conception and building, Operation, Decommissioning. The first part of the paper will go back to waste management lessons and achievements in the design-construction phase and the operating phases of past and present treatment plants. From the past till today's generation, a factor of reduction of 50 for the volume of HLW-ILW type of waste was achieved leading to a ratio of 0.0012 m 3 /GWhe for a burn-up of 45 000 MWd/t! With regards to the development of the next generation of reactors and associated back-end, future improvements appear still possible in waste volume reduction. The second part of the paper will focus on decommissioning, which is likely to generate significant amount of waste, whose removal, handling, sorting, measurement, treatment and conditioning represent a substantial part of the cost of the program.

    The modernization of Reactor I and C, consisting of reactor limitation system, reactor control system and rod control system, at Unterweser NPP is the pilot application of the state-of-the-art safety I and C system TELEPERM XS. The Unterweser system has been integrated and tested from December 1996 to May 1997 in the Siemens Erlangen test field and has been installed at site in July 1997. For the period from July 1997 to Jul 1998 the new TELEPERM XS based Reactor I and C system will be operated online-open-loop in parallel to the existing system, in order to get information about the long term stability of the system and conduct intensive personnel training. For one selected function ''Power distribution control'' the operator has the possibility to choose between the old controller and the new TELEPERM XS function. During the 1998 outage the TELEPERM XS system will be connected to the process and the old I and C system will be dismantled. This document describes the experiences gathered during system integration in the test field. (author)

    CERN. Geneva

    2007-01-01

    The LHC construction is now approaching the end and it is now time to prepare for commissioning with beam. The behavior of a proton storage ring is much different to that of LEP, which profited from strong radiation damping to keep the beam stable. Our last experience with a hadron collider at CERN goes back more than 15 years when the proton-antiproton collider last operated. Ppbar taught us a lot about the machine physics of bunched beam proton storage rings and was essential input for the design of the LHC. After a short presentation of where we stand today with machine installation and hardware commissioning, I will discuss the main machine physics issues that will have to be dealt with in the LHC.

  18. Perspectives of Super-Heavy Nuclei research with the upcoming separator-spectrometer setup S3 at GANIL/SPIRAL2 - The VAMOS Gas-Filled separator and AGATA

    Science.gov (United States)

    Theisen, Christophe

    2017-11-01

    Several facilities or apparatus for the synthesis and spectroscopy of the Super-Heavy Nuclei (SHN) are presently under construction in the world, which reflect the large interest for this region of extreme mass and charge, but also for the need of even more advanced research infrastructures. Among this new generation, the GANIL/SPIRAL2 facility in Caen, France, will soon deliver very high intense ion beams of several tens of particle μA. The Super Separator Spectrometer S3 has been designed to exploit these new beams for the study of SHN after separation. It will provide the needed beam rejection, mass selection and full arsenal of state-of-the art detection setups. Still at GANIL, the AGATA new generation gamma-ray tracking array is being operated. The VAMOS high acceptance spectrometer is being upgraded as a gas-filled separator. Its coupling with AGATA will lower the spectroscopic limits for the prompt gamma-ray studies of heavy and super-heavy nuclei. In this proceeding, these new devices will be presented along with a selected physics case.

  19. Experiments in progress: The geography of science in the Atomic Energy Commission's peaceful uses of nuclear explosives program, 1956-1973

    Science.gov (United States)

    Kirsch, Scott Lawrence

    From 1957 to 1973, the United States Atomic Energy Commission (AEC) actively pursued the "peaceful uses of nuclear explosives" through Project Plowshare. Nuclear excavation, the detonation of shallowly buried hydrogen bombs for massive earthmoving projects like harbors and canals, was considered the most promising of the Plowshare applications, and for a time, the most economically and technically "feasible." With a basis in and contributing to theory in critical human geography and science studies, the purpose of this dissertation is to examine the collisions of science, ideology, and politics which kept Plowshare designs alive--but only as "experiments in progress." That is, this research asks how the experimental program persisted in places like the national weapons laboratory in Livermore, California, and how its ideas were tested at the nuclear test site in Nevada, yet Plowshare was kept out of those spaces beyond AEC control. Primary research focuses on AEC-related archival materials collected from the Department of Energy Coordination and Information Center, Las Vegas, Nevada, and from the Lawrence Livermore National Laboratory, as well as the public discourse through which support for and opposition to Plowshare projects was voiced. Through critical analysis of Plowshare's grandiose "geographical engineering" schemes, I thus examine the complex relations between the social construction of science and technology, on one hand, and the social production of space, on the other.

    SNO+ is a multipurpose liquid scintillator neutrino experiment based at SNOLAB in Sudbury, Ontario, Canada. The experiment’s main physics goal is a search for neutrinoless double beta decay in Tellurium-130, but SNO+ will also study low energy solar neutrinos, geo- and reactor-antineutrinos, among other topics. We are reusing much of the hardware from the original SNO experiment, but significant work has taken place to transform the heavy water detector into a liquid scintillator detector. We present upgrades and improvements to the read-out electronics and trigger system to handle the higher data rates expected by a scintillator experiment. We show the successful installation and testing of a hold-down rope net for the acrylic vessel to counter-act the buoyancy of organic liquid scintillator. We also describe the new scintillator process plant and cover gas systems that have been constructed to achieve the purification necessary to meet our physics goals. We are currently commissioning the experiment with ultra-pure water in preparation for filling with scintillator in early 2017 and present the current status of this work.

  7. National Bioethics Commissions as Educators.

    2017-05-01

    As has become tradition, executive directors of United States' presidential bioethics committees offer reflections about their experience shortly after the orderly shutdown of the commission staff. After the records are filed according to government records regulations; after all the staff members, who are hired into temporary positions that must be renewed every two years, have secured permanent employment; after preparations are made to ensure that the next commission staff (should there be one) has a budget and standard operating procedures in order to begin its work in a timely manner; after the lights are turned out for the last time, the executive director makes the final climb up the stairs into the sunlight and reflects on the whirlwind. There is much about my work with the Presidential Commission for the Study of Bioethical Issues that deserves comment, but one aspect of the commission that has been especially valuable to me is its work to educate the nation on bioethical issues. This is, moreover, a contribution in which the commission staff was central, and it is one that, as an ethics educator myself, I will cherish deeply. © 2017 The Hastings Center.

    The LHC is an accelerator with unprecedented complexity where the energy stored in magnets and the beams exceeds other accelerators by one-to-two orders of magnitude. To ensure a safe and efficient machine start-up without being plagued by technical problems, a phase of "hardware commissioning" was introduced: a thorough commissioning of technical systems without beam. This activity started in June 2005 with the commissioning of individual systems, followed by operating a full sector, one eighth of the machine; the commissioning is expected to last until spring 2008 when commissioning with beam will start. The LHC architecture allows the commissioning of each of the eight sectors independently from the others, before the installation of other sectors is complete. An important effort went into the definition of the programme and the organization of the coordination in the field, as well as in the preparation of the tools to record and analyze test results. This paper discusses the experience with this approach...

    Due to the large amount of energy stored in magnets and beams, safety operation of the LHC is essential. The commissioning of the LHC machine protection system will be an integral part of the general LHC commissioning program. A brief overview of the LHC Machine Protection System will be given, identifying the main components: the Beam Interlock System, the Beam Dumping System, the Collimation System, the Beam Loss Monitoring System and the Quench Protection System. An outline is given of the commissioning strategy of these systems during the different commissioning phases of the LHC: without beam, injection and the different phases with stored beam depending on beam intensity and energy.

  11. Guidelines for residential commissioning

    Energy Technology Data Exchange (ETDEWEB)

    Wray, Craig P.; Walker, Iain S.; Sherman, Max H.

    2003-01-31

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify problems or to correct them. Residential commissioning is a solution to this problem. This guide is the culmination of a 30-month project that began in September 1999. The ultimate objective of the project is to increase the number of houses that undergo commissioning, which will improve the quality, comfort, and safety of homes for California citizens. The project goal is to lay the groundwork for a residential commissioning industry in California focused on end-use energy and non-energy issues. As such, we intend this guide to be a beginning and not an end. Our intent is that the guide will lead to the programmatic integration of commissioning with other building industry processes, which in turn will provide more value to a single site visit for people such as home energy auditors and raters, home inspectors, and building performance contractors. Project work to support the development of this guide includes: a literature review and annotated bibliography, which facilitates access to 469 documents related to residential commissioning published over the past 20 years (Wray et al. 2000), an analysis of the potential benefits one can realistically expect from commissioning new and existing California houses (Matson et al. 2002), and an assessment of 107 diagnostic tools for evaluating residential commissioning metrics (Wray et al. 2002). In this guide, we describe the issues that non-experts should consider in developing a commissioning program to achieve the benefits we have identified. We do this by providing specific recommendations about: how to structure the commissioning process, which diagnostics to use, and how to use them to commission new and existing houses. Using examples, we also demonstrate the potential benefits of applying the recommended whole-house commissioning approach to

  12. Optimization of the commissioning period of nuclear power plant

    2014-01-01

    Due to current equipment manufacture capacity, construction experience and other factors, commissioning of nuclear power projects was used to be postponed, which could lead to delay of the whole project. Based on the actual situation, optimization of commissioning period and its logic could be an effective way to improve this situation to some extent. Based on previous practice and experience in the schedule management for the commissioning nuclear power projects, this paper analyzes and discusses the characteristics of make commissioning plan and the difficulties of program implementation and strategies of commissioning plan optimization, discusses and presents ways of dynamic plan adjustment and optimization at the vision of entire project, synthesizes the methods of time management through commissioning itself, interface and management, expounds measures for the timing and optimization of commissioning schedule and commissioning period, and sums up the ways of optimization of commissioning period, improving management capabilities and control of optimization principles.

    What is a commission within the Staff Association (SA)? A commission is a working group of the CERN Staff Council, led by a staff representative. The commission is composed mainly of staff representatives, but interested members of the SA can apply to participate in the work of a commission. What is the commission on legal matters? The commission on legal matters works on texts governing the employment conditions of staff (Employed Members of Personnel and Associated Members of Personnel). This covers legal documents such as the Staff Rules and Regulations, administrative and operational circulars, as well as any other document relating to employment conditions. How is the work organised in this commission? The revision process of the text is generally done along following lines: The HR department, and its legal experts, proposes new texts or modifications to existing texts. A schedule for the study of these texts is established each year and this calendar by the commission to plan its work. The new or modi...

    2006-01-01

    An important milestone has been passed in the preparation of the injector complex to supply ions to the LHC experiments. The LEIR lead-ion beam, seen on one of the control screens just before the PS injection region. The Low-Energy Ion Ring - LEIR for short - has passed its first tests with flying colours. On 12 May, the ring that will accumulate lead ions for the LHC was shut down after seven months of tests (see Bulletin 44/2005). 'The commissioning phase was a resounding success,' enthuses a satisfied Michel Chanel, head of the LEIR construction project. After several months of fine-tuning, the LEIR team has achieved its aim of producing the kind of beam required for first lead-ion collisions in the LHC in 2008. This involved creating bunches containing 230 million ions, in line with the specifications for those first beams. This success can be put down to the machine's outstanding design and components. 'It's a great achivement by all the teams involved in the machine's construction,' underlines Christian...

    In year 2008 the Atomic Energy National Commission (CNEA) of Argentina, and the Brazilian Institute of Energetic and Nuclear Research (IPEN), under the frame of Nuclear Energy Argentine Brazilian Agreement (COBEN), among many others, included the project “Validation and Verification of Calculation Methods used for Research and Experimental Reactors . At this time, it was established that the validation was to be performed with models implemented in the deterministic codes HUEMUL and PUMA (cell and reactor codes) developed by CNEA and those ones implemented in MCNP by CNEA and IPEN. The necessary data for these validations would correspond to theoretical-experimental reference cases in the research reactor IPEN/MB-01 located in São Paulo, Brazil. The staff of the group Reactor and Nuclear Power Studies (SERC) of CNEA, from the argentine side, performed calculations with deterministic models (HUEMUL-PUMA) and probabilistic methods (MCNP) modeling a great number of physical situations of de reactor, which previously have been studied and modeled by members of the Center of Nuclear Engineering of the IPEN, whose results were extensively provided to CNEA. In this paper results for critical configurations are shown. (author)

  14. Commissioning of the Atlas pixel detector and search of the Higgs boson in the tt-H, H → bb- channel with the Atlas experiment at the LHC

    International Nuclear Information System (INIS)

    Aad, G.

    2009-09-01

    The global fit of Higgs boson quantum contributions to the electroweak experimental observables, computed within the Standard Model, favors a light Higgs boson with a mass of m H = 90 -27 +36 GeV, on the edge of the 95% Confidence Level region excluded by LEP. Finding a light Higgs boson at LHC is experimentally difficult and several channels with various signatures will be sought for. The associated production of the Higgs boson with a pair of top quarks, with the subsequent decay of the Higgs boson into b-quark pairs (dominant for m H <135 GeV), is one of the channels considered. This channel opens the possibility of measuring the top and b-quark Yukawa couplings. The potential of the ATLAS detector to observe this channel is described. Several ingredients are crucial: the reconstruction of the top-anti-top system with a high-purity, excellent b-tagging capabilities and good knowledge of the tt-bar+jets background. The pixel detector is the most important ATLAS sub-detectors for tagging b -jets. The ATLAS detector was commissioned with cosmic muon rays in autumn 2008. The pixel detector dead channels, calibration constants and slow control informations are described for this period. A detailed study about pixel noise determination and suppression is presented. Finally, the pixel detection efficiency is measured using cosmic muon rays. (author)

    P5 Commissioning activities The commissioning effort at the pit has made major progress since the last CMS week concerning the installation and operation of the off-detector electronics in USC. The progress has been much slower in the experi¬mental cavern due to the delay in the deployment of the infrastructure which should eventually allow safe powering-up of the front ends. Nevertheless, temporary power connections have allowed operation of slices of subdetectors at any given time. HF, HE, ECAL, DTs, RPCs and CSCs have carried out local commissioning tests with these temporary services.

    ATF2 is a final-focus test beam line that aims to focus the low-emittance beam from the ATF damping ring to a beam size of about 37 nm, and at the same time to demonstrate nm beam stability, using numerous advanced beam diagnostics and feedback tools. The construction has been finished at the end of 2008 and the beam commissioning of ATF2 has started in December of 2008. ATF2 is constructed and commissioned by ATF international collaborations with strong US, Asian and European participation.

  5. Commissioning the Linac Coherent Light Source injector

    Directory of Open Access Journals (Sweden)

    R. Akre

    2008-03-01

    Full Text Available The Linac Coherent Light Source is a SASE x-ray free-electron laser (FEL project presently under construction at SLAC [J. Arthur et al., SLAC-R-593, 2002.]. The injector section, from drive laser and rf photocathode gun through first bunch compressor chicane, was installed in the fall of 2006. The initial system commissioning with an electron beam was completed in August of 2007, with the goal of a 1.2-micron emittance in a 1-nC bunch demonstrated. The second phase of commissioning, including second bunch compressor and full linac, is planned for 2008, with FEL commissioning in 2009. We report experimental results and experience gained in the first phase of commissioning, including the photocathode drive laser, rf gun, photocathode, S-band and X-band rf systems, first bunch compressor, and the various beam diagnostics.

  6. The upgraded Pixel detector and the commissioning of the Inner Detector tracking of the ATLAS experiment for Run-2 at the Large Hadron Collider

    CERN Document Server

    AUTHOR|(INSPIRE)INSPIRE-00019188; The ATLAS collaboration

    2016-01-01

    Run-2 of the Large Hadron Collider (LHC) will provide new challenges to track and vertex reconstruction with higher energies, denser jets and higher rates. Therefore the ATLAS experiment has constructed the first 4-layer Pixel detector in HEP, installing a new Pixel layer, also called Insertable B-Layer (IBL). The IBL is a fourth layer of pixel detectors, and has been installed in May 2014 at a radius of 3.3 cm between the existing Pixel Detector and a new smaller radius beam-pipe. The new detector, built to cope with the high radiation and expected occupancy, is the first large scale application of 3D detectors and CMOS 130~nm technology. In addition, the Pixel detector was refurbished with a new service quarter panel to recover about 3% of defective modules lost during Run-1 and a new optical readout system to readout the data at higher speed while reducing the occupancy when running with increased luminosity. Complementing detector improvements, many improvements to Inner Detector track and vertex reconstr...

    2010-01-01

    A commission studying past, present, and future social stakes ! For many years we have been hearing about the problems of funding of health insurance benefits in our different Member States. At CERN we are not totally immune from this problem.  To start with, let us recall that we have a mutual-benefit scheme which covers everyone for the consequences of the uncertainties in life (illness and accidents). The rules of our scheme are established by CERN in the framework of a sub-group of the Standing Concertation Committee, the CERN Health Insurance Scheme Board (CHISB), which is also in charge of managing the scheme.  The work of the “ProtSoc” (Protection Sociale – Social Security) commission, as we like to call it at the Staff Association, is to help your representatives on the CHISB, by preparing together with them the subjects and positions to be put forward and defended. This commission, which groups together the staff delegates who wish to invest their ...

    A major experimental program has been established at the Chalk River Nuclear Laboratories (CRL) that will provide essential data on the thermal and mechanical behaviour of nuclear fuel under abnormal reactor operating conditions and on the transient release, transport and deposition of fission product activity from severely degraded fuel. A number of severe fuel damage (SFD) experiments will be conducted within the Blowdown Test Facility (BTF) at CRL. A series of experiments are being conducted to commission this new facility prior to the SFD program. This paper describes the features and the commissioning program for the BTF. A development and testing program is described for critical components used on the reactor test section. In-reactor commissioning with a fuel assembly simulator commenced in 1989 June and preliminary results are given. The paper also outlines plans for future all-effects, in-reactor tests of CANDU-designed fuel. (author). 11 refs., 3 tabs., 7 figs.

  16. A Guide to Building Commissioning

    Energy Technology Data Exchange (ETDEWEB)

    Baechler, Michael C.

    2011-09-01

    Commissioning is the process of verifying that a building's heating, ventilation, and air conditioning (HVAC) and lighting systems perform correctly and efficiently. Without commissioning, system and equipment problems can result in higher than necessary utility bills and unexpected and costly equipment repairs. This report reviews the benefits of commissioning, why it is a requirement for Leadership in Energy and Environmental Design (LEED) certification, and why building codes are gradually adopting commissioning activities into code.

    In September 2008, the large hadron collider (LHC) at CERN was switched on with successful tests of circulating beam in both directions of the ring. The ATLAS semiconductor tracker (SCT) has been installed in the ATLAS cavern since summer 2007 and then integrated with the rest of the ATLAS subdetectors, in preparation for this event. After the SCT was assembled on the surface, the process of being commissioned using cosmic ray events began, and continued after the SCT was installed in the cavern with the rest of the ATLAS detector. Performance results will be given for the recent cosmic runs.

    The Commission 4 Organizing Committee began its work for the 2009-2012 triennium by revising the commission's terms of reference, which serve as our ``mission statement.'' The new terms of reference are:(a)Maintain cooperation and collaboration between the national offices providing ephemerides, prediction of phenomena, astronomical reference data, and navigational almanacs.(b)Encourage agreement on the bases (reference systems, time scales, models, and constants) of astronomical ephemerides and reference data in the various countries. Promote improvements to the usability and accuracy of astronomical ephemerides, and provide information comparing computational methods, models, and results to ensure the accuracy of data provided.(c)Maintain databases, available on the Internet to the national ephemeris offices and qualified researchers, containing observations of all types on which the ephemerides are based. Promote the continued importance of observations needed to improve the ephemerides, and encourage prompt availability of these observations, especially those from space missions, to the science community.(d)Encourage the development of software and web sites that provide astronomical ephemerides, prediction of phenomena, and astronomical reference data to the scientific community and public.Promote the development of explanatory material that fosters better understanding of the use and bases of ephemerides and related data.

    Since the first modules of the ATLAS LAr calorimeters were read out in situ in 2006, commissioning studies have been performed. These studies include the testing of the electronics calibration system, surveys for dead or problematic channels, investigations of the quality of the physics pulse shape prediction , and tests of energy and time reconstruction with cosmic or single beam induced signals. The results of these commissioning studies indicate the LAr calorimeters are prepared for LHC collisions and positioned to meet the physics objectives of the ATLAS experiment.

    The Ground Test Accelerator (GTA) is being used to resolve the physics and engineering issues related to accelerating, focusing, and steering a high-brightness, high-current H - beam and then neutralizing it. The goal is to produce a 24 MeV, 50 mA device with a 2% duty factor. Specific features of the GTA -- injector, beam optics, rf linac structures, diagnostics, control and rf power systems are described. The first four steps in commissioning have been completed. The RFQ predicted and measured performances are in good agreement; however, the transmission is lower than specifications. Input emittance is larger than design specifications and increases the effects of image charge and multipoles. Displacement of steering magnets in either the horizontal or vertical plane caused beam displacements in both planes. It is suspected that quadrupole rotation is the cause of the coupled motion. 9 figs., 5 tabs., 11 refs

    2005-01-01

    A collaboration project between the Safety Commission (SC) and the Controls, Safety and Engineering databases group (TS/CSE) started last year. The aim of this collaboration is to transfer several SC applications from their local environments onto the D7i-MTF EDMS framework, for which the TS/CSE group is responsible. Different domains of activity and projects have been defined in the areas of equipment management, safety inspections, accidents and risks management. Priorities have been established in collaboration with SC. This paper presents the new Safety Inspections Management system (SIM) which will be put in production before the summer 2005 and reviews the constraints of both the users and the development and operational framework that needed to be taken into account. The technical solutions adopted to assure a successful production start-up and operation of the SIM system are described. Progress on other on-going projects and plans for the next year are also reported.

    The NHS, yet again, is in transition with an emphasis on groups of general practitioners (GPs) (clinical commissioning groups) making decisions on which specialist services should be chosen for patients requiring referral from primary care. It is an area of new terminology with a new language and further change for all working in the NHS and the all-important interface between primary and secondary care, and its impact on teamwork. There are many drivers including choice, efficiency, franchising of services, coordination and leadership in an enormous organisation, but not least reducing costs and keeping to a budget. There are many logistical issues and ethical anxieties, and only time will inform patients, practitioners, stakeholders and politicians as to its success.

  8. SSCL Commissioning and Operations

    International Nuclear Information System (INIS)

    1992-01-01

    The SSC, with an energy of 20 TeV/Beam, requires a sequence of individual accelerators of increasing energy in the injector chain. These are the Linac, Low Energy Booster, Medium Energy Booster, and High Energy Booster. Each accelerator system must be completed in sequence in order to provide beam to the next higher energy accelerator. The collider itself is comprised of ten sectors, each of which in terms of superconducting magnet bending strength, is equivalent to two HEB injectors. The completion of all injectors and collider sectors is required before stored beams can circulate in preparation for colliding beam operation. Four experimental halls are planned for the detector systems. Each major detector will be assembled in one of the halls by a world-wide collaboration of scientists. In addition, above ground facilities provide shops and test facilities for accelerator technical systems, superconducting magnet and materials research and development, and for detector assembly and operations. The purpose of this report is to present a plan for the sequential commissioning and operation of these individual accelerators and other technical facilities of the SSC. A central objective of this plan is to describe the activities at the SSCL that are not included as part of the construction project TPC, even though they occur during the overall project construction time-frame. Examples of such activities include the operation of general laboratory facilities and services not specifically related to construction, the operating costs for the individual accelerators in the injector chain once these facilities have been commissioned, and the costs of SSCL physics research groups. The Department of Energy has provided the following decision with regard to these operations categories for the SSCL

    Full Text Available The purpose of this study was to examine the relationship among Procuring Cause Law, real estate agent years of experience, and real estate commission disputes. A pilot survey was conducted in the southwestern United States among real estate agents, realtor(s, and brokers. After testing the hypothesis, the decision was made to fail to reject the hypothesis and conclude that real estate agent experience and not Procuring Cause Law produced favorable outcomes in disputes. As a result, the following recommendations were made: (a Agency seller and buyer’s agreements should be used in each transaction to avoid disputes, (b proper expectations and guidelines should be reviewed prior to starting any real estate transaction, (c a checklist may assist in the assurance that all valuable information is reviewed, (d agents could benefit from fully understanding Procuring Cause Law and sharing this information with their clients, (e state and national regulatory requirements of the law could be modified for easier understanding and use, and (f consumers who willfully violate the law could be subject to monetary penalties.

  16. Liberalism, authority, and bioethics commissions.

    Science.gov (United States)

    MacDougall, D Robert

    2013-12-01

    Bioethicists working on national ethics commissions frequently think of themselves as advisors to the government, but distance themselves from any claims to actual authority. Governments however may find it beneficial to appear to defer to the authority of these commissions when designing laws and policies, and might appoint such commissions for exactly this reason. Where does the authority for setting laws and policies come from? This question is best answered from within a normative political philosophy. This paper explains the locus of moral authority as understood within one family of normative political theories--liberal political theories--and argues that most major "liberal" commentators have understood both the source and scope of ethics commissions' authority in a manner at odds with liberalism, rightly interpreted. The author argues that reexamining the implications of liberalism for bioethics commissions would mean changing what are considered valid criticisms of such commissions and also changing the content of national bioethics commission mandates. The author concludes that bioethicists who participate in such commissions ought to carefully examine their own views about the normative limits of governmental authority because such limits have important implications for the contribution that bioethicists can legitimately make to government commissions.

    This presentation described a wind farm post-commissioning study conducted at a wind farm owned by Helimax Energy Inc. The farm was located in a partly-forested, partly cultivated region in Quebec that featured gently rolling hills. Over 600 dwellings were located within 2 km of the wind farm, and 44 dwellings were within the wind farm's boundaries. The noise impact assessments were conducted at various points near the wind farm. The wind farm was designed using an International Standards Organization (ISO) noise propagation model and a 40 dBA to provide adequate setbacks. The study was conducted using 10 days of continuous measurements at selected points of a wind farm. Points of reception included points from 650 m to 800 m. Noise over 2 km was not thought to be contributed by the wind turbine. The nearest dwelling was 512 m from one of the farm's wind turbines. The study also considered ground factor, temperature, relative humidity, and the height of the receptors. Quebec noise level limits are 40 dBA at night, and 45 dBA during the day. Noise level limits are independent of wind speed. Measured noise contributions over 40 dBA were not observed during the measurement program. The wind turbines were only audible for 1 night out of the 30 night study period. It was concluded that the ISO noise propagation model is a reliable tool for conducting noise impact assessments. tabs., figs

    The ATLAS Readout group (a sub-group of TDAQ) has now completed the installation and commissioning of all of the Readout System (ROS) units. Event data from ATLAS is initially handled by detector specific hardware and software, but following a Level 1 Accept the data passes from the detector specific Readout Drivers (RODs) to the ROS, the first stage of the central ATLAS DAQ. Within the final ATLAS TDAQ system the ROS stores the data and on request makes it available to the Level 2 Trigger (L2) processors and to the Event Builder (EB) as required. The ROS is implemented as a large number of PCs housing custom built cards (ROBINs) and running custom multi-threaded software. Each ROBIN card (shown below) contains buffer memories to store the data, plus a field programmable gate array ( FPGA ) and an embedded PowerPC processor for management of the memories and data requests, and is implemented as a 64-bit 66 MHz PCI card. Both the software and the ROBIN cards have been designed and developed by the Readout g...

    The most intensely discussed and controversial issue in time keeping has been the proposal before the International Telecommunications Union (ITU) to redefine Coordinated Universal Time (UTC) so as to replace leap seconds by leap hours. Should this proposal be adopted, the practice of inserting leap seconds would cease after a specific date. Should the Earth's rotation continue to de-accelerate at its historical rate, the next discontinuity in UTC would be an hour inserted several centuries from now. Advocates of this proposal cite the need to synchronize satellite and other systems, such as GPS, Galileo, and GLONASS, which did not exist and were not envisioned when the current system was adopted. They note that leap second insertions can be and have been incorrectly implemented or accounted for. Such errors have to date had localized impact, but they could cause serious mishaps involving loss of life. For example, some GPS receivers have been known to fail simply because there was no leap second after a long enough interval, other GPS receivers failed because the leap second information was broadcast more than three months in advance, and some commercial software used for internet time-transfer Network Time Protocol (NTP) could either discard all data received after a leap second or interpret it as a frequency change. The ambiguity associated with the extra second could also disrupt financial accounting and certain forms of encryption. Those opposed to the proposal question the need for a change, and also point out the costs of adjusting to the proposed change and its inconvenience to amateur astronomers and others who rely upon astronomical calculations published in advance. Reports have been circulated that the cost of checking and correcting software to accommodate the new definition of UTC would be many millions of dollars for some systems. In October 2005 American Astronomical Society asked the ITU for a year's time to study the issue. This commission has

    Presented are the general description of the SSC linac and the plans for commissioning. Sections of the linac are installed, tested, and beam commissioned in a serial approach. A specialized set of diagnostics is used to characterize the beam through each section. In addition to the standard diagnostic set, plans call for the use of a bunch shape monitor and x-ray spectrometer. Streak camera and digital imaging diagnostics will be developed. The commissioning plan is folded into the general linac project schedule to show the relation between delivery, staging, installation, conditioning, and actual commissioning with beam. These plans form the basis for coordination between the various organizations responsible for different elements of the linac including the technical components, infrastructure, and temporary staging and operation facilities.

    The National Synchrotron Light Source II at Brookhaven National Lab is a third-generation synchrotron radiation facility that has been commissioned in 2014. The facility is based on a 3 GeV electron storage ring, which will circulate 500 mA of beam current at 1 nm rad horizontal emittance. The storage ring is 792 meters in circumference and will accommodate more than 60 beamlines in the final built-out. The beamline sources range from insertion-devices located in straight sections, bending magnets or three-pole-wigglers configured in multiple branches. The NSLS-II storage ring commissioning was successfully completed in July 2014 and the facility delivered the first user light on October 23, 2014. Currently the storage ring reached 300 mA beam current and achieved 1 nm rad of horizontal emittance with 3 sets of Damping Wigglers. At this point six NSLS-II project beamlines are routinely taking photons with beam current at 150 mA. This paper reviews the NSLS-II accelerator design and commissioning experience.

    2008-01-01

    The ATLAS pixel detector is a high precision silicon tracking device located closest to the LHC interaction point. It belongs to the first generation of its kind in a hadron collider experiment. It will provide crucial pattern recognition information and will largely determine the ability of ATLAS to precisely track particle trajectories and find secondary vertices. It was the last detector to be installed in ATLAS in June 2007, has been fully connected and tested in-situ during spring and summer 2008, and is ready for the imminent LHC turn-on. The highlights of the past and future commissioning activities of the ATLAS pixel system are presented

  18. COMMISSIONING AND DETECTOR PERFORMANCE GROUPS

    CERN Multimedia

    D. Acosta

    The commissioning effort is presently addressing two main areas: the commissioning of the hardware components at the pit and the coordination of the activities of the newly constituted Detector Performance groups (DPGs). At point 5, a plan regarding the service cavern and the commissioning of the connections of the off-detector electronics (for the data collection line and trigger primitive generation) to the central DAQ and the central Trigger has been defined. This activity was started early February and will continue until May. It began with Tracker electronics followed so far by HCAL and CSC. The goal is to have by May every detector commission, as much as possible, their data transfer paths from FED to Central DAQ as well as their trigger setups between TPGs and Global Level 1 trigger. The next focus is on connections of front-ends to the service cavern. This depends strongly on the installations of services. Presently the only detector which has its link fibers connected to the off-detector electr...

  19. Commissioning the CMS alignment and calibration framework

    International Nuclear Information System (INIS)

    Futyan, David

    2010-01-01

    The CMS experiment has developed a powerful framework to ensure the precise and prompt alignment and calibration of its components, which is a major prerequisite to achieve the optimal performance for physics analysis. The prompt alignment and calibration strategy harnesses computing resources both at the Tier-0 site and the CERN Analysis Facility (CAF) to ensure fast turnaround for updating the corresponding database payloads. An essential element is the creation of dedicated data streams concentrating the specific event information required by the various alignment and calibration workflows. The resulting low latency is required for feeding the resulting constants into the prompt reconstruction process, which is essential for achieving swift physics analysis of the LHC data. This report discusses the implementation and the computational aspects of the alignment and calibration framework. Recent commissioning campaigns with cosmic muons, beam halo and simulated data have been used to gain detailed experience with this framework, and results of this validation are reported.

    Evans, Lyndon R

    2007-01-01

    The installation of the Large Hadron Collider at CERN is now approaching completion. All magnets are installed with the exception of a few inner triplet quadrupoles. The first of the eight machine sectors is cold and power tests are proceeding. Two other sectors are ready for cool down and interconnect work is proceeding at a satisfactory pace in the other five sectors. In view of a number of accumulated delays, the original plan for partial commissioning of the machine and a low energy pilot run at the end of 2007 will now have to be abandoned. Instead, the full commissioning of the machine to top energy in a single step will start once the injector chain becomes available in spring 2008.

    CERN Document Server

    T. Camporesi

    The major progress made during the last months has been in the consolidation of services for the +endcaps and three barrel wheels (YB+2, YB+1 and YB0): all subdetectors have now final power connections (including Detector Safety protection), the gas systems have been commissioned for all gas detectors (the recirculation is not yet activated for the RPC though) and detector cooling has also been commissioned. Their integration with final services is the necessary condition for being able to operate larger fractions the detector. Recent weeks have seen full HCAL, more than 50% of EB and full wheels of DTs and CSC being operated using final services. This has not yet translated into major progress of global integration due to major interruptions of central services, which have not allowed the necessary debugging and commissioning time to all the subdetec¬tors and central activities like DAQ and trigger. Moreover the running in of the final central services has introduced instabilities related to the co...

    Barbier, Y

    1991-02-01

    A physician on the consultative committee for noncriminal abortions in the canton of Vaud, Switzerland, offers personal reflections on her view of her role. Physicians at the commission evaluate appeals after an initial refusal, cases of foreigners not residing in the canton for 3 months, and particularly difficult cases referred by colleagues. Members of the commission judge whether the case meets the legal criteria for noncriminal abortions. The procedures followed are basically the same as for any other medical consultation: establishing trust with the patient, gathering and evaluating data on the patient's condition, making a decision and communicating it to the patient, and using the rapport established to further therapeutic and preventive goals. The consultation is of extreme importance to the patient, because it will affect her entire future life. Establishing trust begins before the consultation and is aided by a warm and respectful reception of the woman. During the 1st minute of the consultation, the physician should make introductions, define the function of the interview, and attempt to create an authentic physician-patient relationship. The information gathering stage does not involve a physical examination as the pregnancy has already been confirmed. Linguistic problems may arise with foreign women, but use of an interpreter should be avoided if possible. The physician should seek information on whether both partners are in agreement on the abortion, and about cultural problems likely to affect the patient if the pregnancy is continued or alternatively in case of an abortion. The physician can seek further information if necessary by telephoning the patient's family doctor, social worker, or other sources. The decision should be communicated to the patient by the interviewing physician, and may be made immediately or after a period of reflection. When authorization of an abortion is granted, the patient immediately faces the prospect of the procedure

    When complete, the Continuous Electron Beam Accelerator Facility will house a 4 GeV recirculating linear accelerator containing 42 1/4 cryomodules arrayed in two antiparallel linacs and an injector. Currently, over half of the cryomodules have been installed. Each cryomodule contains eight superconducting niobium 5-cell rf cavities that operate at 1.497 GHz. A cryomodule must provide an energy gain of 20 MeV to the 200 μA beam. The resultant dynamic heat load must be less than 45 W. The cavity parameters that are measured during the commissioning process include the external Q's of the cavity ports, the unloaded Q (Q 0 ) of the cavity as a function of accelerating gradient, and the maximum operating gradient of the cavity. The sensitivity of the resonant frequency to changes in pressure and gradient is also measured. Finally, the mechanical tuners are cycled and characterized. In all cases, the performance of CEBAF cryomodules has exceeded the design requirements. A portable test stand allows local control of the rf system and provides automated data acquisition. This paper describes the cryomodule commissioning hardware, software, and measurements

    2017-01-01

    Accelerator commissioning is the process of preparing an accelerator for beam operations. A typical commissioning period at CERN involves running thousands of tests on many complex systems and machinery to ensure smooth beam operations and correct functioning of the machine protection systems. AccTesting is a software framework which helps orchestrate the commissioning of CERN’s accelerators and it’s equipment systems. This involves running and managing tests provided by various commissioning tools and analyzing their outcomes. Currently, AccTesting only supports a specific set of commissioning tools. In this project, we aim to widen the spectrum of commissioning tools supported by AccTesting by developing a generic and programmable integration framework called Molr, which would enable the integration of more commissioning tools with AccTesting. In this report, we summarize the work done during the summer student project and lay out a brief overview of the current status and next steps for Molr.

    The central commissioning activities have concentrated mostly in the Service cavern. Since early February the central DAQ has been ready to accept connections from FEDs from the various partitions. This has triggered a campaign from all subdetectors to install their readout crates in USC55. Systematic tests of the connections between FEDs and Central DAQ have been scheduled and to date more than 70% of all FED connections have been successfully tested from almost all subdetectors. In March the Level 1 trigger team started deployment of their hardware followed by a campaign of testing the connections between Trigger primitive generators and the corresponding LV1 hardware (Regional Calorimeter Trigger and Global Muon Trigger). The functionality tests are continuing to date by pattern tests of increasing complexity. In April the central DAQ was ready to start FED system tests, which amounts to testing the data reading and trans¬fer-ability from the FEDs to the Filter Units (with or without an actual ...

  11. Setup and commissioning of a cryogenic system for the production of targets to be used in experiments with high energy lasers and heavy ion beams; Aufbau und Inbetriebnahme einer Kryoanlage zur Targeterzeugung fuer Experimente mit Hochenergielasern und Schwerionenstrahlen

    Energy Technology Data Exchange (ETDEWEB)

    Menzel, Jurij Alexander

    2010-02-10

    Part of this work was the development of a cryogenic system to produce solid state targets out of nitrogen and rare gases but also hydrogen and deuterium. For target optimization a portable cryogenic test and development chamber has been set up, which can be used offline at different experimental places. Cryogenic targets with different geometries have been produced. Targets with a high aspect ratio having a thickness of only a few micrometers and transverse sizes of millimeters are of special interest for the envisioned investigations. Such targets permit the generation of laser plasmas with a high degree of homogeneity, thus enabling the measurement of the ion energy loss under well defined conditions. Nevertheless, high aspect ratio targets are technologically demanding. Thus, in view of energy loss experiments a simpler geometry has also been considered. Therefore, cryogenic nitrogen targets with cm sizes have been produced and irradiated by the nhelix high energy laser system. The free electron density of the generated plasma has been measured in the range up to 10{sup 20} cm{sup -3}. The measured electron temperature was about 200 eV. The experimental results have been compared to computer simulations and analyzed. It turned out that simulation and experiment are in good agreement, but the free electron density was too low and inhomogeneous for reliable energy loss experiments. Therefore, further deuterium targets with a high aspect ratio but varying geometries have been produced. These targets have been probed by the UNILAC ion beam and it has been shown that the ion beam can penetrate through them. The targets have also been simultaneously irradiated by the high energy laser systems nhelix and Phelix. The free electron density inside the deuterium plasma has been measured and compared with computer simulations. As in the case of nitrogen plasmas a good agreement has been observed. A new measurement technique has been developed to characterize the target

    The Qinshan CANDU Nuclear Power Plant consists of 2 x 728 MWe CANDU 6 units, built in Zhejiang Province, China, by the Third Qinshan Nuclear Power Company (TQNPC) as the owner and Atomic Energy of Canada Limited (AECL) as the main contractor. The Contract between China National Nuclear Corporation (CNNC) and AECL was signed in November 1996 and became effective on February 12, 1997 with scheduled completion dates of February 12, 2003 for Unit 1 and November 12, 2003 for Unit 2. Unit 1 was declared in-service on December 31, 2002, 43 days ahead of schedule and Unit 2 was declared in service on July 20, 2003, 115 days ahead of schedule. The successful partnership between AECL, Bechtel, Hitachi and TQNPC working as a team is the key to this success. Total commissioning period from first energization of the system service transformer to in-service for both units was 20.7 months, which is significantly better than the experience at other comparable CANDU 6 units. It has clearly demonstrated the benefits of building two units together, about 6 months apart, to achieve optimum utilization of resources already mobilized for the first unit; the second unit is commissioned with less than 40% of the effort required for the first unit. Since in-service to the end of March 2004, Unit 1 has operated at a gross capacity factor of 93% and Unit 2 at 82.5%, including loss of production for one month in August 2003 to repair the failure of turbine LP blades tie-wire.

    Highlights: • Commissioning follows the W7-X structure into appropriate components, subsystems and systems. • Local and integrated commissioning steps are carried out alternately. • An exact and detailed preparation of all commissioning is absolutely necessary. • Templates support instruction manuals, safety analyses, and commissioning instructions. • Because of safety special attention must be paid to the first putting into service. - Abstract: The commissioning of Wendelstein 7-X, the first numerically optimized stellarator, is a new phase in the project. The general planning and execution of the commissioning of the entire W7-X system follow its structure into appropriate components, subsystems and systems. The approach for taking these systems into operation will lead to so-called local commissioning which is usually executed for individual systems in connection with the necessary peripheral devices and auxiliary systems. The subsequent step-wise testing and commissioning of the systems in connection with the central device of W7-X, including the central safety control, and the central data acquisition system is performed in the second step, the so-called integrated commissioning. This leads directly to the preparation of first plasma operation. New organizational and quality management elements have been added to the running system, or existing, proven tools have been modified. The major new organizational structures and tasks and the quality planning and assurance tools are described in more detail. The experience during the first commissioning steps of the vacuum and cryogenic systems is outlined.

    User's perception with regard to the attention they received in healthcare units is increasingly being taken into account by the health service providers in order to improve the quality of their service. Describe how the users perceive the health services provided by the CCINSHAE with regard to the communication with the physicians, the attention of the staff and the adverse personal and institutional experiences and to explore their relation with user's demographic characteristics, health condition, physical limitations to carry out daily activities and service area. A questionnaire was designed to collect information about the user and his/her opinion with regard to the healthcare units, the communication with the physicians, the attention of the staff and the adverse personal and institutional experiences. The data were analyzed with STATA using sample weights. A total of 2,176 individuals were interviewed after they had received attention and represent a population of 1,457,964 users, over 6 months, of the CCINSAHE. We then calculated four binary variables that reflect the perception of the users. These four variables were significantly associated with the type of health unit where the user received attention, schooling, limitations to carry out daily activities, facilities provided to the relatives, family income, the use of alternative medicine, and the area of attention. A fundamental aspect of the service provided by the healthcare institutions is the communication between the physicians and the users. We found that the perception of the users with regard to the communication with the physician, the attention of the staff, and the adverse personal and institutional experiences was associated with the type of healthcare unit. The federal reference hospitals produced the most unfavorable perception while the regional hospitals produced the most favorable impression. This study enables the decision-making personnel to determine what needs to be modified in

    During the summer of 2002, eight superconducting helical spin rotators were installed into RHIC in order to control the polarization directions independently at the STAR and PHENIX experiments. Without the rotators, the orientation of polarization at the interaction points would only be vertical. With four rotators around each of the two experiments, we can rotate either or both beams from vertical into the horizontal plane through the interaction region and then back to vertical on the other side. This allows independent control for each beam with vertical, longitudinal, or radial polarization at the experiment. In this paper, we present results from the first run using the new spin rotators at PHENIX

  15. A Practical Guide for Commissioning Existing Buildings

    1999-05-11

    Although this guide focuses on the retrocommissioning process and its advantages, all three types of commissioning--retrocommissioning, commissioning, and recommissioning--play an equally important role in ensuring that buildings perform efficiently and provide comfortable, safe, and productive work environments for owners and occupants. For new construction and retrofit projects, commissioning should be incorporated early, during design, and last throughout the length of the project. For buildings that were never commissioned, the retrocommissioning process can yield a wealth of cost-saving opportunities while enhancing a building's environment. Finally, once a building is commissioned or retrocommissioned, incorporating recommissioning into the organization's O and M program (by periodically reapplying the original diagnostic testing and checklist procedures) helps ensure that cost savings and other benefits gained from the original process persist over time.

  17. COMMISSIONING AND DETECTOR PERFORMANCE GROUPS (DPG)

    CERN Multimedia

    Tiziano Camporesi

    Pit commissioning activities The last 4 months have seen various major achievements in hardware commissioning, global data taking, readiness of the DPGs to deal with LHC data flows and alignment and calibration workflows. Since February, the global commissioning has been characterized on the one side by more and more of the final CMS detector becoming available for global readout and triggering and on the other side by consolidation of many of the central software infrastructure and of most of the services infrastructure. The reliability of services like cooling, power, gas has markedly improved with respect to what we observed in the second half of 2007.   Of particular note are the delivery of all low voltage power supplies, the commissioning of the final power distribution, the progressive commissioning ( still ongoing)  of the Detector Safety System and of the associated DCS early warning and alarm system. On the detector side, while already we are used to seeing all of HCAL being exe...

    The LHC machine, composed of eight sectors with superconducting magnets and accelerating cavities, requires a complex cryogenic system providing high cooling capacities (18 kW equivalent at 4.5 K and 2.4 W at 1.8 K per sector produced in large cold boxes and distributed via 3.3-km cryogenic transfer lines). After individual reception tests of the cryogenic subsystems (cryogen storages, refrigerators, cryogenic transfer lines and distribution boxes) performed since 2000, the commissioning of the cryogenic system of the first LHC sector has been under way since November 2006. After a brief introduction to the LHC cryogenic system and its specificities, the commissioning is reported detailing the preparation phase (pressure and leak tests, circuit conditioning and flushing), the cool-down sequences including the handling of cryogenic fluids, the magnet powering phase and finally the warm-up. Preliminary conclusions on the commissioning of the first LHC sector will be drawn with the review of the critical points already solved or still pending. The last part of the paper reports on the first operational experience of the LHC cryogenic system in the perspective of the commissioning of the remaining LHC sectors and the beam injection test

    The injector for the National Synchrotron Light Source II (NSLS-II) storage ring consists of a 3 GeV booster synchrotron and a 200 MeV S-band linac. The linac was designed to produce either a single bunch with a charge of 0.5 nC of electrons or a train of bunches up to 300 ns long containing a total charge of 15 nC. The booster was designed to accelerate up to 15 nC each cycle in a train of bunches up to 300 ns long. Linac commissioning was completed in April 2012. Booster commissioning was started in November 2013 and completed in March 2014. All of the significant design goals were satisfied including beam emittance, energy spread, and transport efficiency. While the maximum booster charge accelerated was only 10 nC, this has proven to be more than sufficient for storage ring commissioning and operation. The injector has operated reliably during storage ring operation since then. Results will be presented showing measurements of linac and booster operating parameters achieved during commissioning and initial operation. Operating experience and reliability during the first year of NSLS-II operation will be discussed.

    The ATLAS detector will be exposed to proton proton collisions at a center of mass energy of 14 TeV with the bunch crossing rate of 40 MHz. A three-level trigger system has been designed to reduce this rate down to the level at which only interesting events are fully reconstructed. The level 1 trigger reduces the rate down to 75 kHz via custom-built electronics. The Region of Interest Builder delivers the Region of Interest records to the second level trigger which runs the selection algorithms with the commodity processors and brings the rate further down to ~ 3.5 kHz. Finally the Event Filter reduces the rate down to ~ 200 Hz for permanent storage. We review the trigger and data acquisition architecture and its in situ commissioning using almost full detectors. Results on system functionality and performance based on the cosmic data, early experience on LHC beam in 2008 and preselected simulated events are presented.

  1. Innovative ultrasonics for power plant commissioning

    International Nuclear Information System (INIS)

    Murphy, R.V.; Alikhan, S.

    1983-05-01

    During the commissioning of a nuclear power plant, the usual role of ultrasonics is associated with nondestructive testing of welds. There is, however, a variety of undesirable conditions associated with the fluids carried through the various reactor systems which may be just as important to station operation. A variety of unusual ultrasonic techniques has been developed for testing fluid systems at the Point Lepreau Generating Station. This paper uses the experience gained at the Point Lepreau reactor to illustrate the valuable information which can be gained from these measurements, such as: fluid level in pipes and headers; fluid level in pressure vessels; detection, and sizing of debris in pipes; in situ measurement and verification of orifice condition; detection and location of cavitation, water hammer, valve leakage; quantitative measurement of gate movement within the body of an inservice valve; determination of valve position; detection and imaging of flow separation; detection and location of leaks in concrete containment structures; verification of design flows; balancing of loop flows; and detection of low flow. The application of these techniques at other reactor sites is also discussed

  2. Instrumented home energy rating and commissioning

    2003-05-01

    Currently, houses do not perform optimally or even as many codes and forecasts predict, largely because they are field assembled and there is no consistent process to identify deficiencies or to correct them. Solving this problem requires field performance evaluations using appropriate and agreed upon procedures in the form of a new process called residential commissioning. The purpose of this project is to develop and document these procedures and to demonstrate the value that applying them could provide in both new and existing California houses. This project has four specific objectives: to develop metrics and diagnostics for assessing house performance, to provide information on the potential benefits of commissioning using a whole-house approach, to develop programmatic guidelines for commissioning, and to conduct outreach efforts to transfer project results to industry stakeholders. The primary outcomes from this project are the development of residential commissioning guidelines and the analytical confirmation that there are significant potential benefits associated with commissioning California houses, particularly existing ones. In addition, we have made substantial advances in understanding the accuracy and usability of diagnostics for commissioning houses. In some cases, we have been able to work with equipment manufacturers to improve these aspects of their diagnostic tools. These outcomes provide a solid foundation on which to build a residential commissioning program in California. We expect that a concerted effort will be necessary to integrate such a program with existing building industry efforts and to demonstrate its use in the field.

    The Energy Reorganization Act of 1974 which established the Nuclear Regulatory Commission required GAO to evaluate the Commission's performance by January 18, 1980. This report responds to that requirement. GAO concluded that, although improvements have been made, the Commission's nuclear regulatory performance can be characterized best as slow, indecisive, cautious - in a word, complacent. This has largely resulted from a lack of aggressive leadership as evidenced by the Commissioners' failure to establish regulatory goals, control policymaking, and most importantly, clearly define their roles in nuclear regulation

    The CMS experiment at the Large Hadron Collider (LHC) at CERN is upgrading the photo-detection and readout system of the forward hadron calorimeter (HF). During Long Shutdown 1, all of the original PMTs were replaced with multi-anode, thin window photomultipliers. At the same time, the back-end readout system was upgraded to micro-TCA readout. Here we report on the experience with commissioning and calibrating the HF front-end as well as the online operational challenges of the micro-TCA system.

    1992-01-01

    This paper reports that the process for obtaining Nuclear Regulatory Commission permits for the high level waste storage facility is basically the same process commercial nuclear power plants followed to obtain construction permits and operating licenses for their facilities. Therefore, the experience from licensing commercial reactors can be applied to the high level waste facility. Proper management of the licensing process will be the key to the successful project. The management of the licensing process was categorized into four areas as follows: responsibility, organization, communication and documentation. Drawing on experience from nuclear power plant licensing and basic management principles, the management requirement for successfully accomplishing the project goals are discussed

  13. Commissioning and first data with the ATLAS silicon microstrip tracker

    International Nuclear Information System (INIS)

    Rohne, Ole Myren

    2010-01-01

    The ATLAS experiment at the CERN large hadron collider (LHC) has started taking data this autumn with the inauguration of the LHC. The semiconductor tracker (SCT) is the key precision tracking device in ATLAS, made up from silicon micro-strip detectors processed in the planar p-in-n technology. The completed SCT has recently been installed inside the ATLAS experimental hall. Quick tests were performed last year to verify the connectivity of the electrical and optical services. Problems observed with the heaters for the evaporative cooling system have been resolved. This has enabled extended operation of the full detector under realistic conditions. Calibration data has been taken and analysed to determine the noise performance of the system. In addition, extensive commissioning with cosmic ray events has been performed. The cosmic muon data has been used to align the detector, to check the timing of the front-end electronics as well as to measure the hit efficiency of modules. The current status of the SCT will be reviewed, including results from the latest data-taking periods in autumn 2008, and from the detector alignment. We will report on the commissioning of the detector, including overviews on services, connectivity and observed problems. Particular emphasis will also be placed on the SCT data taken in the latest running period with the entire ATLAS detector participating. The SCT commissioning and running experience will then be used to extract valuable lessons for future silicon strip detector projects.

  14. UNIVERSITY COMMISSION FOR GENDER EQUALITY (CUIG. EXPERIENCE MAINSTREAMING

    Directory of Open Access Journals (Sweden)

    Aurelia Flores-Hernández

    2014-07-01

    Full Text Available Gender mainstreaming suggests institutional reorganization and/or “mainstreaming” of gender at the university. Betting on institutionalization as part of a government policy that requires institutional commitment and the responsibility of all university powers by the advancement of equality between women and men. For certain approaches in the feminist movement, it represents the handling of a struggle in the very long term tension that cannot be bounded exclusively to the enunciation of instances nominal or degraded resource allocation without achieving larger structural changes and prone to genuine equality (Palomar, 2009; Pérez, 2010; Alonso, 2010. Therefore, in this paper seeks to explain the extent to which the proposal or mainstreaming should not own the feminist struggle. The reflection is located in the plane of the Autonomous University of Tlaxcala (UATX, for it challenges facing the institutionalization of gender are presented, based on the following questions: Does the University have a need to mainstream a gender perspective? And, if so, what elements allow this initiative? And, what elements constrain it?

  19. The commissioning of nuclear power plants

    International Nuclear Information System (INIS)

    1989-09-01

    The objectives and requirements to be met in commissioning nuclear power plants are presented. The objective of commissioning is to ensure that each component, subsystem, system, or structure in a plant will be capable of fulfilling its design requirements throughout its design life. The requirements for commissioning are: the preparation of a detailed, comprehensive, documented program to demonstrate that all components, systems and structures relevant to safety meet design intent; documented evidence that safety systems are fully operable and can meet design requirements; and, appropriate documentation of the actual state or behaviour of all components, systems and structures relevant to safety. All systems must be included in the commissioning program. Whenever possible, full safety system test should be performed. If a full system in situ test is not possible, alternative means are suggested. (8 refs.)

  12. arXiv Medical Physics Commissioning

    CERN Document Server

    Meer, David

    The medical commissioning is an important step to bring a particle gantry into clinical operation for tumour treatments. This involves the parametrization and characterization of all relevant systems including the beam delivery, the patient table, the imaging systems and the connection to all required software components. This article is limited to necessary tasks for the beam delivery system of a pencil beam scanning system. Usually the commissioning starts with the characterization of the unscanned beam and the calibration of the beam energy. The following steps are the parametrization of the scanning system, the commissioning of the beam position monitoring system and characterization of the spot size, all requiring precisions better than 1 mm. The commissioning effort for these tasks depends also on the gantry topology. Finally, the calibration of the dose measurement system ensures that any dose distribution can be delivered with an absolute precision better than 1%.

    2009-01-01

    The muon trigger system of the ATLAS experiment consists of several sub-systems and each of them need to be tested and certified before LHC operation. In the barrel region Resistive Plate Chambers are employed. RPC detector and its level-1 trigger electronics are designed to detect and select high momentum muons with high time resolution and good tracking capability for a total surface of about 4000 m2. The commissioning phase provided an unique opportunity to demonstrate, before LHC start-up, the functionality of the muon trigger components such as detector chambers, level-1 trigger electronics, detector slow control system, data acquisition chain, software and computing. We present the status of ATLAS RPC detector, the problems met during the commissioning and the solutions found and, finally, its performances as obtained by acquiring cosmic rays.

    The Spallation Neutron Source (SNS) accelerator delivers a one mega-Watt beam to a mercury target to produce neutrons used for neutron scattering materials research. It delivers ~ 1 GeV protons in short (< 1 us) pulses at 60 Hz. At an average power of ~ one mega-Watt, it is the highest-powered pulsed proton accelerator. The accelerator includes the first use of superconducting RF acceleration for a pulsed protons at this energy. The storage ring used to create the short time structure has record peak particle per pulse intensity. Beam commissioning took place in a staged manner during the construction phase of SNS. After the construction, neutron production operations began within a few months, and one mega-Watt operation was achieved within three years. The methods used to commission the beam and the experiences during initial operation are discussed.

    The Continuous Electron Beam Accelerator Facility (CEBAF) energy upgrade from 6 GeV to 12 GeV includes the installation of eleven new 100 MV cryomodules (88 cavities). The superconducting RF cavities are designed to operate CW at an accelerating gradient of 19.3 MV/m with a Q L of 3x10 7 . Not all the cavities were operated at the minimum gradient of 19.3 MV/m with the beam. Though the initial 12 GeV milestones were achieved during the initial commissioning of CEBAF, there are still some issues to be addressed for long term reliable operation of these modules. This paper reports the operational experiences during the initial commissioning and the path forward to improve the performance of C100 (100 MV) modules.

    We present a novel online ensemble learning strategy for portfolio selection. The new strategy controls and exploits any set of commission-oblivious portfolio selection algorithms. The strategy handles transaction costs using a novel commission avoidance mechanism. We prove a logarithmic regret bound for our strategy with respect to optimal mixtures of the base algorithms. Numerical examples validate the viability of our method and show significant improvement over the state-of-the-art.

    The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. 1993 marked the last full year of the Commission operating as Alberta's representative in the energy regulatory arena in Canada and the USA; due to restructuring, these functions will be transferred to the Ministry of Energy in early 1994. A brief overview is presented of crude oil markets in Canada and the USA. The Commission's receipts of light and medium royalty oil totalled 40.2 million bbl, down 11% from 1992, and receipts of heavy crude were 3.7 million bbl, down 42% from 1992. Revenue from crude oil sales was $800 million, down 25% from 1992. The Commission's natural gas activities in 1993 included price determination and information collection. 4 figs., 3 tabs

  17. Commission errors of active intentions: the roles of aging, cognitive load, and practice.

    Performing an intended action when it needs to be withheld, for example, when temporarily prescribed medication is incompatible with the other medication, is referred to as commission errors of prospective memory (PM). While recent research indicates that older adults are especially prone to commission errors for finished intentions, there is a lack of research on the effects of aging on commission errors for still active intentions. The present research investigates conditions which might contribute to older adults' propensity to perform planned intentions under inappropriate conditions. Specifically, disproportionally higher rates of commission errors for still active intentions were observed in older than in younger adults with both salient (Experiment 1) and non-salient (Experiment 2) target cues. Practicing the PM task in Experiment 2, however, helped execution of the intended action in terms of higher PM performance at faster ongoing-task response times but did not increase the rate of commission errors. The results have important implications for the understanding of older adults' PM commission errors and the processes involved in these errors.

  18. Alberta Petroleum Marketing Commission annual report, 1992

    International Nuclear Information System (INIS)

    1993-05-01

    The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketeer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. 1992 marked the end of chronically depressed natural gas prices and a significant reduction in natural gas surpluses. A brief overview is presented of crude oil markets in Canada and the USA. The Commission's receipts of light and medium royalty oil totalled 45.3 million bbl, unchanged from 1991, and receipts of heavy crude were 6.3 million bbl, up 4% from 1991. Revenue from crude oil sales was $1.1 billion, down from $1.64 billion in 1991. The Commission's natural gas activities in 1992 included price determination and information collection. 9 figs., 1 tab

    The Alberta Petroleum Marketing Commission has the responsibility of selling the Crown's royalty share of Alberta's crude and synthetic oil production; similar services are provided for natural gas. The Commission also markets crude oil on behalf of producers to North American and offshore consumers. The Commission's position as the largest crude oil marketeer in Canada enables it to provide analyses of industry pricing and marketing trends to the Alberta government. In 1991, the middle east crisis caused prices to spike at the commencement of the Gulf war, but these quickly stabilized. The Commission's receipts of light and medium royalty oil totalled 45.3 million bbl, down 1.5% from 1990, and receipts of heavy crude were 6.1 million bbl, up 5% from 1990. Revenue from crude oil sales was $1,642,244,000, down from $2,078,197,000 in 1990. Loss of the Montreal market through pipeline closure led to increased pressure on prices, particularly on heavy crudes. The Commission's natural gas activities in 1991 included price determination and information collection. 9 figs., 1 tab

  20. Impact assessment and policy learning in the European Commission

    International Nuclear Information System (INIS)

    Ruddy, Thomas F.; Hilty, Lorenz M.

    2008-01-01

    Governance for sustainable development requires policy coherence and Environmental Policy Integration, which are being hindered by difficulties coordinating the two separate impact assessment processes being conducted in the European Commission. One of them, the Commission-wide Impact Assessment process, looks primarily at EU-internal impacts, whereas the other one, Sustainability Impact Assessment (SIA) in DG Trade, looks outward to other countries and intergovernmental organizations. Ideally, the two processes should complement one another, especially as the two are set to continue being done in parallel. The paper uses a case study of the reform of the European sugar regime under a World Trade Organization ruling to demonstrate how the two impact assessment processes could better complement one another. Feedback from the experience had with existing trade agreements could then promote policy learning and inform the negotiations on new agreements. The number of new bilateral and Regional Trade Agreements is expected to continue rising, thus increasing the importance of the Commission-wide Impact Assessment process required for them

    2000-07-01

    The Very Large Telescope Interferometer (VLTI) is a complex system, made of a large number of separated elements. To prepare an early successful operation, it will require a period of extensive testing and verification to ensure that the many devices involved work properly together, and can produce meaningful data. This paper describes the concept chosen for the VLTI commissioning instrument, LEONARDO da VINCI, and details its functionalities. It is a fiber based two-way beam combiner, associated with an artificial star and an alignment verification unit. The technical commissioning of the VLTI is foreseen as a stepwise process: fringes will first be obtained with the commissioning instrument in an autonomous mode (no other parts of the VLTI involved); then the VLTI telescopes and optical trains will be tested in autocollimation; finally fringes will be observed on the sky.

    This is a description, based largely on personal discussions, of the contributions of men from the Yale University School of Medicine to the saga of the immediate and long-term studies on the medical effects of the atomic bombs at Hiroshima and Nagasaki. They played key roles in the immediate studies of bomb effects, in the creation of long-term studies of delayed effects, and in elevating the Atomic Bomb Casualty Commission after 1955 to a position of excellence in its studies and relations with the Japanese. The accumulation of the information presented in this paper derives from research for the preparation of the history of the Atomic Bomb Casualty Commission. In 1975, the commission was passed to Japanese leadership as the Radiation Effects Research Foundation

    2011-01-01

    Highlights: → Core safety optimisation through a set of reactivity feedback coefficients allowing to cope with accidental transients. → Reactor optimisation by exploring innovative options for intermediate circuits and steam generators. → Reactor behaviour under accidental conditions including severe accidents to improve the robustness. → Waste management options having both characteristics of efficiency and economics viability. → Promoting European young human resources skills on sodium fast reactors by means of dedicated workshops and doctoral dissertations. - Abstract: Fast Reactors have a unique capability as sustainable energy source; the closed fuel cycle allows significantly improving the usage of natural resources and the minimisation of volume and heat load of high-level waste. Among the fast reactor systems, the sodium-cooled fast reactor has the most comprehensive technological basis, thanks to the experience gained internationally from operating experimental, prototype and commercial size reactors. The paper summarizes the key characteristics of the four years large Collaborative Project on European Sodium Fast Reactor (CP ESFR - 2009-2012); the CP ESFR follows the 6th FP project named 'Roadmap for a European Innovative SOdium cooled FAst Reactor - EISOFAR' further identifying, organizing and implementing a significant part of the needed R and D effort. The CP ESFR merges the contribution of 25 European partners; it is performed under the aegis of the 7th FP under the Area - Advanced Nuclear Systems with a refund from the European Commission of 5.8 M Euro (11.55 M Euro total budget). It is a key component of the European Sustainable Nuclear Energy Technology Platform (SNE TP) and its Strategic Research Agenda (SRA). The inputs for the project are the key research goals for fourth generation of European sodium cooled fast reactors which can be summarized as follows: an improved safety with in particular the achievement of a robust architecture

  2. Challenges of commissioning and contracting for integrated care in the National Health Service (NHS) in England.

    Science.gov (United States)

    Addicott, Rachael

    2016-01-01

    For many years there has been a separation between purchasing and provision of services in the English National Health Service (NHS). Many studies report that this commissioning function has been weak: purchasers have had little impact or power in negotiations with large acute providers, and have had limited strategic control over the delivery of care. Nevertheless, commissioning has become increasingly embedded in the NHS structure since the arrival of Clinical Commissioning Groups (CCGs) in 2012. Recently, some of these CCGs have focused on how they can contract and commission in different ways to stimulate greater collaboration across providers. This paper examines experiences of commissioning and contracting for integrated care in the English NHS, based on a series of national-level interviews and case studies of five health economies that are implementing novel contracting models. The cases illustrated here demonstrate early experiments to drive innovation through contracting in the NHS that have largely relied on the vision of individual teams or leaders, in combination with external legal, procurement and actuarial support. It is unlikely that this approach will be sustainable or replicable across the country or internationally, despite the best intentions of commissioners. Designing and operating novel contractual approaches will require considerable determination, alongside advanced skills in procurement, contract management and commissioning. The cost of developing new contractual approaches is high, and as the process is difficult and resource-intensive, it is likely that dedicated teams or programs will be required to drive significant improvement.

  3. Agency transformation and state public utility commissions

    International Nuclear Information System (INIS)

    Jones, Douglas N.

    2006-01-01

    The demise of public utility commissions has been periodically predicted (sometimes hoped for). In their long history they have been attacked by critics as ineffective, inefficient, expensive, or unnecessary. Further, the demonstrated survivability of the commission concept has often been uncharitably attributed to powerful political constituencies, self-preservation manoeuvrings by commissioners themselves, and inertia. The implications of this article point another way. Commission regulation of public utilities has survived mainly because of continued need for social oversight of these critical industry sectors and the capacity of PUCs strategically to adapt to fundamental changes in their surroundings. Two transformational upheavals are treated here - a challenge of flexibility and responsiveness by the dramatic run-up in costs and prices in the 1970s and challenge to relevance by the policy shift to greater reliance on market competition in the 1990s - and regulation's successful accommodation to them. Viewed this way commission regulation is more in a position of 'second wind' than 'last breath'. (author)

    Coleman, Anna; Segar, Julia; Checkland, Kath; McDermott, Imelda; Harrison, Stephen; Peckham, Stephen

    2015-01-01

    The purpose of this paper is to explore the early experiences of those involved with the development of Clinical Commissioning Groups (CCGs), examining how the aspiration towards a "clinically-led" system is being realised. The authors investigate emerging leadership approaches within CCGs in light of the criterion for authorisation that calls for "great leaders". Qualitative research was carried out in eight case studies (CCGs) across England over a nine-month period (September 2011 to May 2012) when CCGs were in their early development. The authors conducted a mix of interviews (with GPs and managers), observations (at CCG meetings) and examined associated documentation. Data were thematically analysed. The authors found evidence of two identified approaches to leadership - positive deviancy and responsible guardianship - being undertaken by GPs and managers in the developing CCGs. Historical experiences and past ways of working appeared to be influencing current developments and a commonly emerging theme was a desire for the CCG to "do things differently" to the previous commissioning bodies. The authors discuss how the current reorganisation threatens the guardianship approach to leadership and question if the new systems being implemented to monitor CCGs' performance may make it difficult for CCGs to retain creativity and innovation, and thus the ability to foster the positive deviant approach to leadership. This is a large scale piece of qualitative research carried out as CCGs were beginning to develop. It provides insight into how leadership is developing in CCGs highlighting the complexity involved in these roles.

    Nebot-Guinot, M.; NEXT Collaboration

    2017-09-01

    NEXT (Neutrino Experiment with a Xenon TPC) is a neutrinoless double-beta (ββ0ν) decay experiment at the Canfranc Underground Laboratory (LSC). It seeks to detect the ββ0ν decay of Xe-136 using a high pressure xenon gas TPC with electroluminescent (EL) amplification. The NEXT-White (NEW) detector, with an active xenon mass of about 10 kg at 15 bar, is the first NEXT prototype installed at LSC. It implements the NEXT detector concept tested in smaller prototypes using the same radiopure sensors and materials that will be used in the future NEXT-100, serving as a benchmark for technical solutions as well as for the signal selection and background rejection algorithms. NEW is currently under commissioning at the LSC. In this poster proceedings we describe the technical solutions adopted for NEW construction, the lessons learned from the commissioning phase, and the first results on energy calibration and energy resolution obtained with low-energy radioactive source data.

  9. Curriculum for Commissioning Energy Efficient Buildings

    Energy Technology Data Exchange (ETDEWEB)

    Webster, Lia [Portland Energy Conservation, Inc., OR (United States)

    2012-12-27

    In July 2010, the U.S. Department of Energy (DOE) awarded funding to PECI to develop training curriculum in commercial energy auditing and building commissioning. This program was created in response to the high demand for auditing and commissioning services in the U.S. commercial buildings market and to bridge gaps and barriers in existing training programs. Obstacles addressed included: lack of focus on entry level candidates; prohibitive cost and time required for training; lack of hands-on training; trainings that focus on certifications & process overviews; and lack of comprehensive training. PECI organized several other industry players to create a co-funded project sponsored by DOE, PECI, New York State Energy and Research Development Authority (NYSERDA), California Energy Commission (CEC), Northwest Energy Efficiency Alliance (NEEA) and California Commissioning Collaborative (CCC). After awarded, PECI teamed with another DOE awardee, New Jersey Institute of Technology (NJIT), to work collaboratively to create one comprehensive program featuring two training tracks. NJIT’s Center for Building Knowledge is a research and training institute affiliated with the College of Architecture and Design, and provided e-learning and video enhancements. This project designed and developed two training programs with a comprehensive, energy-focused curriculum to prepare new entrants to become energy auditors or commissioning authorities (CxAs). The following are the key elements of the developed trainings, which is depicted graphically in Figure 1: • Online classes are self-paced, and can be completed anywhere, any time • Commissioning Authority track includes 3 online modules made up of 24 courses delivered in 104 individual lessons, followed by a 40 hour hands-on lab. Total time required is between 75 and 100 hours, depending on the pace of the independent learner. • Energy Auditor track includes 3 online modules made up of 18 courses delivered in 72 individual

    2015-10-15

    The Joint European Torus (JET) is the largest tokamak currently in operation in the world. One of the greatest challenges of JET is the integrated commissioning of all its major plant systems. This is driven, partially, by the size and complexity of its operational infrastructure and also by the fact that, being an international environment, it has to address the issues of integrating, commissioning and maintaining plant systems developed by third parties. The ITER tokamak, now in construction, is a fusion device twice the size of JET and, being a joint effort between the European Union, China, India, Japan, South Korea, the Russian Federation and the USA, it will share on a wider scale all of the JET challenges regarding integration and integrated commissioning of very large and complex plant systems. With the scope of taking advantage from the history and experience of JET, Fusion for Energy (F4E) has worked together with the Culham Centre for Fusion Energy (CCFE), the host and operator of JET, for the provision of ITER relevant user experiences related to the integrated commissioning of the tokamak. This work presents and discusses the main results and the methods that were used to extract and translate the commissioning experience information into ITER requirements.

  11. Commissioning of long subsea pipelines - environmental aspects

    International Nuclear Information System (INIS)

    Falck, C.; Kleppe, T.; Maribu, J.

    1997-01-01

    Discharges to air and sea are inevitable during precommissioning and commissioning of long subsea pipelines. Large quantities of water is pumped through the pipeline during these operations. This water is normally treated with corrosion inhibiting chemicals to minimise internal corrosion of the pipeline. Chemicals like methanol or glycol may be used to prevent hydrate formation, and will normally be discharged to sea during commissioning. In order to minimise the environmental impact of these operations, while maintaining corrosion protection, the Norwegian Statoil has been working for several years along three main routes such as to develop concepts and methods that minimise the discharged volumes, the use of the most environmentally friendly chemicals available, and to monitor and identify the effects of discharges to various marine species. 3 refs., 4 figs

    1978-01-01

    Mr. Jenkins, President of the Commission, first examines the problem of the economy and the level of its unemployment in the Community, resulting in a lack of growth. He than presents the two-fold aim of the Commission--to instigate emergency action to sustain industries that are no longer fully competitive and to promote economic growth to provide employment and prosperity. He then examins the energy and agriculture sectors. Two obligations cited for the Community are: (1) to defend Community interests in the energy field in relation to Third World Countries, and (2) to make clear the connections between energy policy and the general economic strategy. Negotiations are underway for enlargement of the community with applications being considered for Greece, Portugal, and Spain. A memorandum annexed to the address contains additional material on building an integrated economic unit, the European citizen and his environment, Europe in the world, and enlargement of the community.

  13. A History of the Atomic Energy Commission

    Science.gov (United States)

    Buck, Alice L.

    1983-07-01

    This pamphlet traces the history of the US Atomic Energy Commission's twenty-eight year stewardship of the Nation's nuclear energy program, from the signing of the Atomic Energy Act on August 1, 1946 to the signing of the Energy Reorganization Act on October 11, 1974. The Commission's early concentration on the military atom produced sophisticated nuclear weapons for the Nation's defense and made possible the creation of a fleet of nuclear submarines and surface ships. Extensive research in the nuclear sciences resulted in the widespread application of nuclear technology for scientific, medical and industrial purposes, while the passage of the Atomic Energy Act of 1954 made possible the development of a nuclear industry, and enabled the United States to share the new technology with other nations.

  14. LHC Damper Beam commissioning in 2010

    CERN Document Server

    Höfle, W; Schokker, M; Valuch, D

    2011-01-01

    The LHC transverse dampers were commissioned in 2010 with beam and their use at injection energy of 450 GeV, during the ramp and in collisions at 3.5 TeV for Physics has become part of the standard operations pro- cedure. The system proved important to limit emittance blow-up at injection and to maintain smaller than nominal emittances throughout the accelerating cycle. We describe the commissioning of the system step-by-step as done in 2010 and summarize its performance as achieved for pro- ton as well as ion beams in 2010. Although its principle function is to keep transverse oscillations under control, the system has also been used as an exciter for abort gap clean- ing and tune measurement. The dedicated beam position measurement system with its low noise properties provides additional possibilities for diagnostics.

    This pamphlet traces the history of the US Atomic Energy Commission's twenty-eight year stewardship of the Nation's nuclear energy program, from the signing of the Atomic Energy Act on August 1, 1946 to the signing of the Energy Reorganization Act on October 11, 1974. The Commission's early concentration on the military atom produced sophisticated nuclear weapons for the Nation's defense and made possible the creation of a fleet of nuclear submarines and surface ships. Extensive research in the nuclear sciences resulted in the widespread application of nuclear technology for scientific, medical and industrial purposes, while the passage of the Atomic Energy Act of 1954 made possible the development of a nuclear industry, and enabled the United States to share the new technology with other nations

    The SPIRAL2 injector, installed in its tunnel, is currently under commissioning at GANIL, Caen, France. The injector is composed of two low energy beam transport lines: one is dedicated to the light ion beam production, the other to the heavy ions. The first light ion beam, created by a 2.45 GHz electron cyclotron resonance ion source, has been successfully produced in December 2014. The first beam of the PHOENIX V2 18 GHz heavy ion source was analyzed on 10 July 2015. A status of the SPIRAL2 injector commissioning is given. An upgrade of the heavy ion source, named PHOENIX V3 aimed to replace the V2, is presented. The new version features a doubled plasma chamber volume and the high charge state beam intensity is expected to increase by a factor of 1.5 to 2 up to the mass ∼50. A status of its assembly is proposed.
