  2. TRIO experiment

    International Nuclear Information System (INIS)

    The TRIO experiment is a test of in-situ tritium recovery and heat transfer performance of a miniaturized solid breeder blanket assembly. The assembly (capsule) was monitored for temperature and neutron flux profiles during irradiation and a sweep gas flowed through the capsule to an anaytical train wherein the amounts of tritium in its various chemical forms were determined. The capsule was designed to operate at different temperatures and sweep gas conditions. At the end of the experiment the amount of tritium retained in the solid was at a concentration of less than 0.1 wppM. More than 99.9% of tritium generated during the experiment was successfully recovered. The results of the experiment showed that the tritium inventories at the beginning and at the end of the experiment follow a relationship which appears to be characteristic of intragranular diffusion

    A cybernetic model has been developed to elucidate some of the main principles of the growth regulation system in the epidermis of the hairless mouse. A number of actual and theoretical biological experiments have been simulated on the model. These included simulating the cell kinetics as measured by pulse labelling with tritiated thymidine and by continuous labelling with tritiated thymidine. Other simulated experiments included steady state, wear and tear, painting with a carcinogen, heredity and heredity and tumour. Numerous diagrams illustrate the results of these simulated experiments. (JIW)

  7. Experiment Databases

    Science.gov (United States)

    Vanschoren, Joaquin; Blockeel, Hendrik

    Next to running machine learning algorithms based on inductive queries, much can be learned by immediately querying the combined results of many prior studies. Indeed, all around the globe, thousands of machine learning experiments are being executed on a daily basis, generating a constant stream of empirical information on machine learning techniques. While the information contained in these experiments might have many uses beyond their original intent, results are typically described very concisely in papers and discarded afterwards. If we properly store and organize these results in central databases, they can be immediately reused for further analysis, thus boosting future research. In this chapter, we propose the use of experiment databases: databases designed to collect all the necessary details of these experiments, and to intelligently organize them in online repositories to enable fast and thorough analysis of a myriad of collected results. They constitute an additional, queriable source of empirical meta-data based on principled descriptions of algorithm executions, without reimplementing the algorithms in an inductive database. As such, they engender a very dynamic, collaborative approach to experimentation, in which experiments can be freely shared, linked together, and immediately reused by researchers all over the world. They can be set up for personal use, to share results within a lab or to create open, community-wide repositories. Here, we provide a high-level overview of their design, and use an existing experiment database to answer various interesting research questions about machine learning algorithms and to verify a number of recent studies.

  9. Channeling experiment

    International Nuclear Information System (INIS)

    Channeling of water flow and tracer transport in real fractures in a granite body at Stripa have been investigated experimentally. The experimental site was located 360 m below the ground level. Two kinds of experiments were performed. In the single hole experiments, 20 cm diameter holes were drilled about 2.5 m into the rock in the plane of the fracture. Specially designed packers were used to inject water into the fracture in 5 cm intervals all along the fracture trace in the hole. The variation of the injection flowrates along the fracture were used to determine the transmissivity variations in the fracture plane. Detailed photographs were taken from inside the hole and the visual fracture aperture was compared with the injection flowrates in the same locations. Geostatistical methods were used to evaluate the results. Five holes were measured in great detail. In addition 7 holes were drilled and scanned by simpler packer systems. A double hole experiment was performed where two parallel holes were drilled in the same fracture plane at nearly 2 m distance. Pressure pulse tests were made between the holes in both directions. Tracers were injected in 5 locations in one hole and monitored for in many locations in the other hole. The single hole experiment and the double hole experiment show that most of the fracture planes are tight but that there are open sections which form connected channels over distances of at least 2 meters. It was also found in the double hole experiment that the investigated fracture was intersected by at least one fracture between the two holes which diverted a large amount of the injected tracers to several distant locations at the tunnel wall.

    We describe extensive computational experiments on spectral properties of random objects - random cubic graphs, random planar triangulations, and Voronoi and Delaunay diagrams of random (uniformly distributed) point sets on the sphere). We look at bulk eigenvalue distribution, eigenvalue spacings, and locality properties of eigenvectors. In all cases we discover completely new (at least to this author) phenomena.

  12. Shielding experiments

    International Nuclear Information System (INIS)

    Shielding mock-up experiments for Prototype Fast Breeder Reactor (PFBR) and Advanced Heavy Water Reactor (AHWR) are carried out in shielding corner facility of APSARA reactor, to assess the overall accuracy of the codes and nuclear data used in reactor shield design. As APSARA is a swimming pool-type thermal reactor, for fast reactor experiments, typical fast reactor shielding facility was created by using uranium assemblies as spectrum converter. The flux was also enhanced by replacing water by air. Experiments have been carried out to study neutron attenuation through typical fast reactor radial and axial bulk shielding materials such as steel, sodium, graphite, borated graphite and boron carbide. A large number of reaction rates, sensitive to different regions of the neutron energy spectrum, were measured using foil activation and Solid State Nuclear Track Detector (SSNTD) techniques. These experimental results were analysed using computational tools normally used in design calculations, viz., discrete ordinate transport codes with multigroup cross section sets. Comparison of measured reaction rates with calculations provided suitable bias factors for parameters relevant to shield design, such as sodium activation, fast neutron fluence, fission equivalent fluxes etc. The measured neutron spectrum on the incident face of shield model compares well with the calculated fast reactor blanket leakage neutron spectrum. The comparison of calculated reaction rates within shield model indicate that the calculations suffer from considerable uncertainties, in shield models with boron carbide/borated graphite. For AHWR shielding experiments, no spectrum converter was used as it is also a thermal reactor. Radiation streaming studies through penetrations/ducts of various shapes and sizes relevant to AHWR shielding were carried out. (author)

  13. Russian experience

    International Nuclear Information System (INIS)

    Soviet research in terrestrial decontamination appears to have paralleled that of the US in many respects. However, the probability exists that long-term evaluations of decontamination techniques (over 10 to 20 years) have been carried out at one nuclear accident site (a marked divergence from US experience). The area of aquatic decontamination seems to offer the most intriguing possibilities for new information acquisition from the USSR; at this point only its potential importance can be speculated upon

    MM II defined a series of experiments to better understand and characterize model transport and to assess the realism of this transport by comparison to observations. Measurements from aircraft, balloon, and satellite, not yet available at the time of MM I [Prather and Remsberg, 1993], provide new and stringent constraints on model transport, and address the limits of our transport modeling abilities. Simulations of the idealized tracers the age spectrum, and propagating boundary conditions, and conserved HSCT-like emissions probe the relative roles of different model transport mechanisms, while simulations of SF6 and C02 make the connection to observations. Some of the tracers are related, and transport diagnostics such as the mean age can be derived from more than one of the experiments for comparison to observations. The goals of the transport experiments are: (1) To isolate the effects of transport in models from other processes; (2) To assess model transport for realistic tracers (such as SF6 and C02) for comparison to observations; (3) To use certain idealized tracers to isolate model mechanisms and relationships to atmospheric chemical perturbations; (4) To identify strengths and weaknesses of the treatment of transport processes in the models; (5) To relate evaluated shortcomings to aspects of model formulation. The following section are included:Executive Summary, Introduction, Age Spectrum, Observation, Tropical Transport in Models, Global Mean Age in Models, Source-Transport Covariance, HSCT "ANOY" Tracer Distributions, and Summary and Conclusions.

    The measurement of the production of particles coming from hard scattering processes covers a fundamental role in the characterization of the system formed in heavy-ion collisions, allowing to probe the microscopic processes underlying the interaction of high energy partons with the medium. An impressive amount of measurements related to jet, quarkonia, open heavy flavor, and electroweak signal production in nucleus-nucleus as well as p(d)-nucleus collisions was delivered by experiments at RHIC and LHC in past years. In these proceedings, the main experimental results presented during the Hard Probes conference are summarized.

  19. Thomson Experiment

    CERN Multimedia

    This experiment, conducted by JJ Thomson in 1897, established the existence of the electron. Thomson won the Nobel physics prize for this work in 1906. A beam of electrons crosses the chamber emitting blue light. Adding an electric field (E) or a magnetic field (B) exerts a force on the moving electrons.Use switch E to turn on the electric field in the chamber. Then, by turning knob B, you can increase the current in the coils, generating a magnetic field. By balancing the electric and magnetic fields, Thomson was able to keep the electron beam level and deduce the ratio of the electron's charge to its mass.

  20. TRISTAN experiment

    International Nuclear Information System (INIS)

    Any successor to PETRA and PEP colliders was expected to extend the energy range to the region where the weak interaction effect becomes sizable in annihilation process. The aim was to reach the level, at which the all round study of the standard model can be performed in a clean system of e+e- collision. Also it was aimed to explore the energy region where top quark pair production is likely. Considering the available site for accelerator construction and the expected size of the electroweak interference effect, the target energy was set at 60 GeV at the lowest. TRISTAN-1 experiment is a big initial step in the long range physics program. The laboratory established the plan to move on to TRISTAN-2 (B Factory) project. The TRISTAN accelerator including the main storage ring, the time sequence of storage ring operation, three experimental groups of AMY, TOPAZ and VENUS, and so on are explained. The experiments on basic annihilation process, the search for new particles, the electroweak interaction, QCD studies and so on are reported. The optimum TRISTAN ring was estimated as 3 km in diameter, but the largest possible size in the site was 1/3 of that. Hard decision was made to equip the ring with unusually many accelerating RF cavities and to apply superconducting technology. (K.I.)

  1. Operating experience

    International Nuclear Information System (INIS)

    In 1987, Westinghouse Hanford Company began operating a first-generation integrated safeguards system in the Plutonium Finishing Plant storage vaults. This Vault Safety and Inventory System is designed to integrate data into a computer-based nuclear material inventory monitoring system. The system gathers, in real time, measured physical parameters that generate nuclear material inventory status data for thousands of stored items and sends tailored report to the appropriate users. These data include canister temperature an bulge data reported to Plant Operations and Material Control and Accountability personnel, item presence and identification data reported to Material Control and Accountability personnel, and unauthorized item movement data reported to Security response forces and Material Control and Accountability personnel. The Westinghouse Hanford Company's experience and operational benefits in using this system for reduce radiation exposure, increase protection against insider threat, and real-time inventory control are discussed in this paper

  2. Rutherford Experiment

    CERN Document Server

    This experiment, carried out by Ernest Rutherford in 1910, revolutionised understanding of the structure of matter, showing that almost all the mass of an atom is concentrated in a very small, positively charged nucleus. Alpha particles emitted at bombard a thin gold foil. A detector records the number of alpha particles crossing the foil per second. The number is displayed on the counter and updated every minute. Alpha particles are helium nuclei, they consist of 2 protons and 2 neutrons. Rotate the central knob to change the angle between the foil and the detector. The number of alpha particles detected depends on the angle. Most of the alpha particles travel straight through the foil because the gold atoms are mainly empty space. However some hit the atomic nucleus and are deflected.

    It is well known that bees cluster together in cold weather, in the process of swarming (when the ``old'' queen leaves with part of the colony) or absconding (when the queen leaves with all the colony) and in defense against intruders such as wasps or hornets. In this paper we describe a fairly different clustering process which occurs at any temperature and independently of any special stimulus or circumstance. As a matter of fact, this process is about four times faster at 28 degree Celsius than at 15 degrees. Because of its simplicity and low level of ``noise'' we think that this phenomenon can provide a means for exploring the strength of inter-individual attraction between bees or other living organisms. For instance, and at first sight fairly surprisingly, our observations showed that this attraction does also exist between bees belonging to different colonies. As this study is aimed at providing a comparative perspective, we also describe a similar clustering experiment for red fire ants.

    The goal of the Grid is to provide a coherent access to distributed computing resources. All LHC experiments are using several Grid infrastructures and a variety of the middleware flavors. Due to the complexity and heterogeinity of a distributed system the monitoring represents a challenging task. Independently of the underlying platform , the experiments need to ave a complete and uniform picture of their activities on the Grid ideally seen by the users as a single powerful computing resource. Overall operation of the infrastructure used by experiments is defined both by the quality of the Grid and the quality of the tools and services developed/used by the experiments. Correspondingly the required monitoring information should combine both Grid-related and experiment/application specific data. On the other hand, users of the LHC experiments have various roles and need different levels of details regarding monitoring data. The paper will focus on the Grid monitoring from the experiment/user perspectives with...

    Popper's original thought experiment probed some fundamental and subtle rules of quantum mechanics. Two recent experiments have tested Popper's hypothesis, but they seem to give contrasting results and one suggests a violation of Heisenberg's uncertainty principle. The equations governing these two experiments and Popper's thought experiment will be derived from basic principles. The experimental constants will be inputted and it will show that the two experiments agree with each other. It will be shown that no uncertainty relations are violated and that Popper's thought experiment was fundamentally flawed.

In this paper, we take a pragmatic approach to identifying key aspects of an experience design process, by reporting on a project involving the design of experience-oriented applications of interactive technologies for knowledge dissemination and marketing, in cooperation with public institutions and businesses. We argue that collaborative formulation of core design intentions and values is a valuable instrument in guiding experience design processes, and present three cases from this project, two of which resulted in interactive installations. The case installations range from walk-up-and-use consoles, to immersive, responsive, environments based on bodily interaction. We compare the installations, and discuss the interrelations between the resulting interfaces and the intentions for creating the installations, the core values established to guide the design process and the intended use contexts. We argue that the installations present a broad spectrum of experience design installations that can assist designers in understanding the relations between core values, intentions, use context and interface in the design of experience-oriented interactive installations.

    Experiments in Physical Chemistry, Second Edition provides a compilation of experiments concerning physical chemistry. This book illustrates the link between the theory and practice of physical chemistry. Organized into three parts, this edition begins with an overview of those experiments that generally have a simple theoretical background. Part II contains experiments that are associated with more advanced theory or more developed techniques, or which require a greater degree of experimental skill. Part III consists of experiments that are in the nature of investigations wherein these invest

  12. Experience Communication and Aesthetics

    DEFF Research Database (Denmark)

    Thorlacius, Lisbeth

    In this article the term "experience communication" will be introduced and discussed. It will be illustrated how different concepts of aesthetical experiences are an integrated part of experience communication and how these concepts are produced within the industries of consumerism, branding and entertainment. With a point of departure in Immanuel Kant's "the sublime" (2005, orig. 1790); Edmund Burke's " the sublime" (1998, orig. 1757); " Jean Francois Lyotard's "the sublime" (1984); Mihaly Csikszentmihalyi's "flow ", (1997); Roland Barthes' "punctum" (1987) " and David Favrholdt's "the inexpressible experience"( 2000), a survey of different forms of aesthetical experiences in connection with the field of experience communication will be presented. In addition to the more established concepts of the aesthetical experience this article introduces a new term " the interference" which is  an aesthetical experience which is relevant in regards to some of the aesthetical experiences which we are met with within the industry of experience communication. The term "interference"  in the context of experience communication can be described as a kind of "intrusion," capable of creating a certain type of beauty in the form of a new aesthetic expression. An aesthetic expression which is based on "interference" denotes the space that may exist between what we know and what we don't know. With a point of departure in empirical studies it will be illustrated how these different concepts of the aesthetical experiences are produced within the field of experience communication. Aesthetical experiences may be a product of the concept of novelty, the unpredictable, the inexpressible, the making of identity, the self-actualization, the self-staging, the interactive aspect, the co-producer role (the prosumer role), the user to user aspect (web 2.0), the personal engagement or the community spirit. This increasing demand of experiences reflects the postmodern cultural trends where rules for how to think and behave no longer exist. Thisresults in individualism, where the identity of the human being has changed from something which was a given to something which each human being has to manage individually. As a consequence the human being experiences an increasing sense of insecurity and restless seeking after identity and recognition, which is reflected in an increasing demand of among other things self-actualization. The individualization of the human being can lead to loneliness and a need of participating in communities as a replacement of an overall fixed point in one's life. (Anthony Giddens, 1990, 1991; Zygmunt Bauman, 1997; Carsten René Jørgensen, 2002). The field of communication is consequently experiencing a great challenge in terms of creating experience based communication designs which meet the need of self-actualization and creation of own identities of the target audiences.

    2015-07-01

    The non-zero neutrino mixing angle ?13 has been discovered and precisely measured by the current generation short-baseline reactor neutrino experiments. It opens the gate of measuring the leptonic CP-violating phase and enables the neutrino mass ordering. The JUNO and RENO-50 proposals aim at resolving the neutrino mass ordering using reactors. The experiment design, physics sensitivity, technical challenges as well as the progresses of those two proposed experiments are reviewed in this paper.

    This project focuses on the aesthetic experience. The main question is whether the aesthetic experience can be qualified, which we have tried to do using philosophy. We use theories of Hans-Georg Gadamer in relation to hermeneutics and play, and theories by Theodor Adorno about natural beauty and art beauty. Throughout the project we relate these theories to our own experiences, both personal reflections and in relation to Peter Greenaway's film: "The Pillow Book" which we analyse. F...

    Blindsight is classically defined as residual visual capacity, e.g., to detect and identify visual stimuli, in the total absence of perceptual awareness following lesions to V1. However, whereas most experiments have investigated what blindsight patients can and cannot do, the literature contains several, often contradictory, remarks about remaining visual experience. This review examines closer these remarks as well as experiments that directly approach the nature of possibly spared visual expe...

    Experience understood as experience-based consumption is by now fairly absent from the research agenda of the different theories on sustainable consumption. On the basis of Colin Campbell’s notion of romantic ethics and emotional sentimentality in modern hedonism, I claim that sustainable consumption may re-enchant ordinary consumption and thereby even become a part of marketing and the experience economy. New layers of meaning are at stake and altruistic motives come into play; doing somethi...

  1. Molybdenum solar neutrino experiment

    International Nuclear Information System (INIS)

    The goal of the molybdenum solar neutrino experiment is to deduce the 8B solar neutrino flux, averaged over the past several million years, from the concentration of 98Tc in a deeply buried molybdenum deposit. The experiment is important to an understanding of stellar processes because it will shed light on the reason for the discrepancy between theory and observation of the chlorine solar neutrino experiment. Possible reasons for the discrepancy may lie in the properties of neutrinos (neutrino oscillations or massive neutrinos) or in deficiencies of the standard solar model. The chlorine experiment only measures the 8B neutrino flux in current times and does not address possible temporal variations in the interior of the sun, which are also not considered in the standard model. In the molybdenum experiment, we plan to measure 98Tc (4.2 Myr), also produced by 8B neutrinos, and possibly 97Tc (2.6 Myr), produced by lower energy neutrinos

    Cryogenic systems will be used by LHC experiments to maximize their performance. Institutes around the world are collaborating with CERN in the construction of these very low temperature systems. The cryogenic test facility in hall 180 for ATLAS magnets. High Energy Physics experiments have frequently adopted cryogenic versions of their apparatus to achieve optimal performance, and those for the LHC will be no exception. The two largest experiments for CERN's new flagship accelerator, ATLAS and CMS, will both use large superconducting magnets operated at 4.5 Kelvin - almost 270 degrees below the freezing point of water. ATLAS also includes calorimeters filled with liquid argon at 87 Kelvin. For the magnets, the choice of a cryogenic version was dictated by a combination economy and transparency to emerging particles. For the calorimeters, liquid argon was selected as the fluid best suited to the experiment's physics requirements. High Energy Physics experiments are the result of worldwide collaborations and...

Positive indications of nonzero lepton mixing follow from studies of the solar and atmospheric neutrinos. (author). 95 refs, 11 figs

In addition to the neutrino discovery and the precision measurement of neutrino oscillation parameters of θ12 and Δm 221, there is a major achievement very recently by the Daya Bay, RENO and Double Chooz experiments. They discovered the non-zero neutrino mixing angle, θ13, hence completed the picture of neutrino oscillations. The next generation reactor neutrino experiments will be able to determine the neutrino mass hierarchy and improve significantly the precision of θ12, Δm221 and Δm231. Reactor neutrino experiments can be also used to study sterile neutrinos.

This experiment looks at energy transformation from potential to kinetic energy, where the smaller parts of the egg shell spread far from the center of the impact. This experience encouraged the pre-service science teachers to use their familiar models, such as a fried egg, omelet, puddle, dropping or explosions, to explain their predictions. These models from everyday life presented can be used as a tool to explain unfamiliar phenomena.

    Ferrimagnetism undoubtedly deserves a proper place in the undergraduate laboratory on electricity and magnetism. Four student experiments on ferrimagnetism are considered: (i) the hysteresis loops and permeability of a ‘soft’ ferrite; (ii) the differential permeability versus a dc bias; (iii) the frequency dependence of the complex permeability and (iv) the electromagnetic interference suppression by ferrite chokes and beads. Two ferrite cores taken off a low-frequency choke and a power cord are used. The measurements are simple and straightforward and show the important properties of ferrites and their applications. The values of the permeability of the ferrite core determined in experiments (i)-(iii) are in reasonable agreement. The frequency dependence of the complex permeability of the ferrites is similar to that given by the manufacturers. The capability of absorbing electromagnetic waves in a definite frequency range shown in experiment (iv) demonstrates one of the principles of Stealth technology. The equipment necessary for the experiments can be found in many student laboratories.

    Full Text Available In this article we wish to introduce and discuss a theoretical framework for a possible conceptualisation of the differences between reading a printed book and listening to an audiobook. We tend to introduce similarities and differences between reading with the eyes and reading with the ears, implying that we should not discuss the audiobook experience as a remediation of the printed book experience only, but as an entirely different experience that could be conceptualised in continuation of mobile listening practises. As a methodological strategy we will emphasise the differences between the literary practices, reading with the eyes and reading with the ears. These different perspectives on reading are used to accentuate the distinct experiences, and future thorough analyses in continuation of this framework would appear much more complex and connected than in the present article.

  2. Experiment-o-mania

    Every 21st century student is expected to develop science literacy skills. As this is not part of Serbian national curriculum yet, we decided to introduce it with this project. Experiment-o-mania provides students to experience science in different and exciting way. It makes opportunity for personalized learning offering space and time to ask (why, where, how, what if) and to try. Therefore, we empower young people with skills of experimenting, and they love science back. They ask questions, make hypothesis, make problems and solve them, make mistakes, discuss about the results. Subsequently this raises the students' interest for school curriculum. This vision of science teaching is associated with inquiry-based learning. Experiment-o-mania is the unique and recognizable teaching methodology for the elementary school Drinka Pavlović, Belgrade, Serbia. Experiment-o-mania implies activities throughout the school year. They are held on extra class sessions, through science experiments, science projects or preparations for School's Days of science. Students learn to ask questions, make observations, classify data, communicate ideas, conduct experiments, analyse results and make conclusions. All science teachers participate in designing activities and experiments for students in Experiment-o-mania teaching method. But they are not alone. Teacher of fine arts, English teachers and others also take part. Students have their representatives in this team, too. This is a good way to blend knowledge among different school subject and popularize science in general. All the experiments are age appropriate and related to real life situations, local community, society and the world. We explore Fibonacci's arrays, saving energy, solar power, climate change, environmental problems, pollution, daily life situations in the country or worldwide. We introduce great scientists as Nikola Tesla, Milutin Milanković and sir Isaac Newton. We celebrate all relevant international days, weeks, months or years (this year, 2015. the students will prepare opera science for celebrate the International Year of Light and International Year of Soils). Experiment-o-mania makes science teaching and learning exciting for teachers as well as for students. The acquisition of this kind of teaching method (and its frequency) empowers students and become self-regulated learners, independent, to creatively solve problems, to innovate, to truly understand and appreciate science and to better understand themselves and the world around them.

    Employment of a data-acquisition system for data collection and calculations makes experiments with antennas more convenient and less time consuming. The determined directional patterns of the dipole antennas of different lengths are in reasonable agreement with theory. The enhancement of the signal by using a reflector is demonstrated, and a variant of the Yagi-Uda antenna is explored. The experiments are suitable as laboratory works and classroom demonstrations, and are attractive for student projects.

  5. Review of experiments

    International Nuclear Information System (INIS)

    A study was made to examine the effects which raising the ISA from 200 x 200 GeV to 400 x 400 GeV would have on the ''canonical'' experiments. These were ''canonical'' in the sense that they span the full range of foreseeable physics and have served as topics in previous Summer Studies and Workshops which resulted in quite explicit hardware designs and experimental goals. The study results indicate that all of the ''canonical'' experiments survive. Some are actually improved, some are unaffected, and some require changes which are suggested. In general, the 900 experiments are relatively unaffected. The single arm small angle spectrometer, the wide aperture (FATS-WASP) spectrometer and the Coulomb interference experiment have the largest number of modifications suggested. No uniqueness to these solutions are claimed, and there may be more desirable radical approaches. It is, however, felt that the 400 x 400 GeV ISA not only permits the work on conceptual experiments from previous Summer Studies to be taken over entirely, but indicates areas of improvement in many of them. Specifics of the individual experiments are discussed

  6. Modal identification experiment

    Kvaternik, Raymond G.

    1992-01-01

    The Modal Identification Experiment (MIE) is a proposed on-orbit experiment being developed by NASA's Office of Aeronautics and Space Technology wherein a series of vibration measurements would be made on various configurations of Space Station Freedom (SSF) during its on-orbit assembly phase. The experiment is to be conducted in conjunction with station reboost operations and consists of measuring the dynamic responses of the spacecraft produced by station-based attitude control system and reboost thrusters, recording and transmitting the data, and processing the data on the ground to identify the natural frequencies, damping factors, and shapes of significant vibratory modes. The experiment would likely be a part of the Space Station on-orbit verification. Basic research objectives of MIE are to evaluate and improve methods for analytically modeling large space structures, to develop techniques for performing in-space modal testing, and to validate candidate techniques for in-space modal identification. From an engineering point of view, MIE will provide the first opportunity to obtain vibration data for the fully-assembled structure because SSF is too large and too flexible to be tested as a single unit on the ground. Such full-system data is essential for validating the analytical model of SSF which would be used in any engineering efforts associated with structural or control system changes that might be made to the station as missions evolve over time. Extensive analytical simulations of on-orbit tests, as well exploratory laboratory simulations using small-scale models, have been conducted in-house and under contract to develop a measurement plan and evaluate its potential performance. In particular, performance trade and parametric studies conducted as part of these simulations were used to resolve issues related to the number and location of the measurements, the type of excitation, data acquisition and data processing, effects of noise and nonlinearities, selection of target vibration modes, and the appropriate type of data analysis scheme. The purpose of this talk is to provide an executive-summary-type overview of the modal identification experiment which has emerged from the conceptual design studies conducted to-date. Emphasis throughout is on those aspects of the experiment which should be of interest to those attending the subject utilization conference. The presentation begins with some preparatory remarks to provide background and motivation for the experiment, describe the experiment in general terms, and cite the specific technical objectives. This is followed by a summary of the major results of the conceptual design studies conducted to define the baseline experiment. The baseline experiment which has resulted from the studies is then described.

  7. Inverse Cerenkov experiment

    International Nuclear Information System (INIS)

    The final report describes work performed to investigate inverse Cherenkov acceleration (ICA) as a promising method for laser particle acceleration. In particular, an improved configuration of ICA is being tested in a experiment presently underway on the Accelerator Test Facility (ATF). In the experiment, the high peak power (? 10 GW) linearly polarized ATF CO2 laser beam is converted to a radially polarized beam. This is beam is focused with an axicon at the Cherenkov angle onto the ATF 50-MeV e-beam inside a hydrogen gas cell, where the gas acts as the phase matching medium of the interaction. An energy gain of ?12 MeV is predicted assuming a delivered laser peak power of 5 GW. The experiment is divided into two phases. The Phase I experiments, which were completed in the spring of 1992, were conducted before the ATF e-beam was available and involved several successful tests of the optical systems. Phase II experiments are with the e-beam and laser beam, and are still in progress. The ATF demonstrated delivery of the e-beam to the experiment in Dec. 1992. A preliminary ''debugging'' run with the e-beam and laser beam occurred in May 1993. This revealed the need for some experimental modifications, which have been implemented. The second run is tentatively scheduled for October or November 1993. In parallel to the experimental efforts has been ongoing theoretical work to support the experiment and investigate improvement and/or offshoots. One exciting offshoot has been theoretical work showing that free-space laser acceleration of electrons is possible using a radially-polarized, axicon-focused laser beam, but without any phase-matching gas. The Monte Carlo code used to model the ICA process has been upgraded and expanded to handle different types of laser beam input profiles

  8. Understanding customer experience.

    2007-02-01

    Anyone who has signed up for cell phone service, attempted to claim a rebate, or navigated a call center has probably suffered from a company's apparent indifference to what should be its first concern: the customer experiences that culminate in either satisfaction or disappointment and defection. Customer experience is the subjective response customers have to direct or indirect contact with a company. It encompasses every aspect of an offering: customer care, advertising, packaging, features, ease of use, reliability. Customer experience is shaped by customers' expectations, which largely reflect previous experiences. Few CEOs would argue against the significance of customer experience or against measuring and analyzing it. But many don't appreciate how those activities differ from CRM or just how illuminating the data can be. For instance, the majority of the companies in a recent survey believed they have been providing "superior" experiences to customers, but most customers disagreed. The authors describe a customer experience management (CEM) process that involves three kinds of monitoring: past patterns (evaluating completed transactions), present patterns (tracking current relationships), and potential patterns (conducting inquiries in the hope of unveiling future opportunities). Data are collected at or about touch points through such methods as surveys, interviews, focus groups, and online forums. Companies need to involve every function in the effort, not just a single customer-facing group. The authors go on to illustrate how a cross-functional CEM system is created. With such a system, companies can discover which customers are prospects for growth and which require immediate intervention. PMID:17345685

  9. Research by retrieving experiments.

    Science.gov (United States)

    Blagosklonny, Mikhail V

    2007-06-01

    Newton did not discover that apples fall: the information was available prior to his gravitational hypothesis. Hypotheses can be tested not only by performing experiments but also by retrieving experiments from the literature (via PubMed, for example). Here I show how disconnected facts from known data, if properly connected, can generate novel predictions testable in turn by other published data. With examples from cell cycle, aging, cancer and other fields of biology and medicine, I discuss how new knowledge was and will be derived from old information. Millions of experiments have been already performed to test unrelated hypotheses and the results of those experiments are available to 'test' your hypotheses too. But most data (99% by some estimates) remain unpublished, because they were negative, seemed of low priority, or did not fit the story. Yet for other investigators those data may be valuable. The well-known story of Franklin and Watson is a case in point. By making preliminary data widely available, 'data-owners' will benefit most, receiving the credit for otherwise unused results. If posted (pre-published) on searchable databases, these data may fuel thousands of projects without the need for repetitive experiments. Enormous 'pre-published' databases coupled with Google-like search engines can change the structure of scientific research, and shrinking funding will make this inevitable. PMID:17525526

  10. IBEX magnetic coupling experiments

    International Nuclear Information System (INIS)

    The magnetic coupling of one pulse to another is a key issue for some modes of high-current beam propagation. Experiments are in progress on Sandia's IBEX accelerator to address issues relevant to magnetic coupling. The IBEX experiments differ from previous experiments in that the B/sub theta/ field acting on the second pulse is the result of residual plasma current from the first pulse rather than current applied by an external means. This new feature makes the propagation sensitive to beam and plasma current profiles that are key to the physics of the magnetic coupling problem. These experiments do not attempt to study the air chemistry issues, as this would require much higher current densities than are available from IBEX. We are using the IBEX accelerator with a mismatched magnetized diode to produce two high-current pulses separated by approx.130 nsec. A pulse pair has been propagated over a 1.5-m path in low pressure air. Extraction of two pulses, each having different parameters, complicates the experiment but also provides new insight into the magnetic coupling proplem. 7 figs

    We present the design and characterization of the POLARBEAR experiment. POLARBEAR will measure the polarization of the cosmic microwave background (CMB) on angular scales ranging from the experiment's 3.5 arcminute beam size to several degrees. The experiment utilizes a unique focal plane of 1,274 antenna-coupled, polarization sensitive TES bolometers cooled to 250 milliKelvin. Employing this focal plane along with stringent control over systematic errors, POLARBEAR has the sensitivity to detect the expected small scale B-mode signal due to gravitational lensing and search for the large scale B-mode signal from inflationary gravitational waves. POLARBEAR was assembled for an engineering run in the Inyo Mountains of California in 2010 and was deployed in late 2011 to the Atacama Desert in Chile. An overview of the instrument is presented along with characterization results from observations in Chile.

    1996-12-01

    Flavorings in foods and fragrances in personal care products is a topic often discussed in chemistry classes designed for the general education of non-science majors. A laboratory experiment has been designed to accompany the lecture topic. Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell. Students are permitted to create their own fragrance based on the results of the experiment. Student response has been favorable. The experiment rectifies misconceptions students have about structure and odor, and gives positive reinforcement to the lecture material.

    2010-01-01

    As part of the Institute for Creative Technologies and the School of Cinematic Arts at the University of Southern California, the Mixed Reality lab develops technologies and techniques for presenting realistic immersive training experiences. Such experiences typically place users within a complex ecology of social actors, physical objects, and collections of intents, motivations, relationships, and other psychological constructs. Currently, it remains infeasible to completely synthesize the interactivity and sensory signatures of such ecologies. For this reason, the lab advocates mixed reality methods for training and conducts experiments exploring such methods. Currently, the lab focuses on understanding and exploiting the elasticity of human perception with respect to representational differences between real and virtual environments. This paper presents an overview of three projects: techniques for redirected walking, displays for the representation of virtual humans, and audio processing to increase stress.

    Experiments on the Large Hadron Collider at CERN represent our furthest excursion yet along the energy frontier of particle physics. The goal of probing physical processes at the TeV energy scale puts strict requirements on the performance of accelerator and experiment, dictating the awe-inspiring dimensions of both. These notes, based on a set of five lectures given at the 2010 Theoretical Advanced Studies Institute in Boulder, Colorado, not only review the physics considered as part of the accelerator and experiment design, but also introduce algorithms and tools used to interpret experimental results in terms of theoretical models. The search for new physics beyond the Standard Model presents many new challenges, a few of which are addressed in specific examples.

  16. Future Reactor Experiments

    CERN Document Server

    2013-01-01

    The measurement of the neutrino mixing angle $\\theta_{13}$ opens a gateway for the next generation experiments to measure the neutrino mass hierarchy and the leptonic CP-violating phase. Future reactor experiments will focus on mass hierarchy determination and the precision measurement of mixing parameters. Mass hierarchy can be determined from the disappearance of reactor electron antineutrinos based on the interference effect of two separated oscillation modes. Relative and absolute measurement techniques have been explored. A proposed experiment JUNO, with a 20 kton liquid scintillator detector of $3%/$$\\sqrt{E(MeV)}$ energy resolution, $\\sim$ 53 km far from reactors of $\\sim$ 36 GW total thermal power, can reach to a sensitivity of $\\Delta\\chi^{2}>16$ considering the spread of reactor cores and uncertainties of the detector response. Three of mixing parameters are expected to be measured to better than 1% precision. There are multiple detector options for JUNO under investigation. The technical challenges...

  17. Thought experiment with tritium

    International Nuclear Information System (INIS)

    An experiment is proposed in which a minimum of thirty (30) grams of tritium is packaged as lithium tritide in a steel container weighing several kilograms. After decontamination of the outside surface, calorimetry measurements would be made, and the unit would be weighed very accurately. After several decades, the calorimeter and weight measurements would be repeated. If the weight measurements could be made with the required accuracy, it would be possible to correlate the observed change in mass with the total energy emitted (calculated from the mean energy measured by calorimetry) over the time interval. If successful, this experiment would, in the opinion of the authors, be the first laboratory experiment to directly verify the equivalency of mass and energy. 4 refs., 2 figs., 3 tabs

  20. Electrophoresis experiments for space

    Science.gov (United States)

    Snyder, Robert S.; Rhodes, Percy H.

    2000-01-01

    It has long been hoped that space could alleviate the problems of large-scale, high-capacity electrophoresis. Support media and reduced chamber dimensions of capillary electrophoresis have established the physical boundaries for Earth-based systems. Ideally, electrophoresis conducted in a virtual weightless environment in an unrestricted ``free'' fluid should have great potential. The electrophoresis and isoelectric focusing experiments done in the reduced gravity over the past twenty-five years have demonstrated the absence of thermal convection and sedimentation as well as the presence of electrohydrodynamics that requires careful control. One commercial venture produced gram amounts of an electrophoretically purified protein during seven Space Shuttle flights but the market disappeared in the six years between experiment conception and performance on the Space Shuttle. Our accumulated experience in microgravity plus theoretical models predict improvements that should be possible with electrophoresis if past problems are considered and both invention of new technologies and innovation of procedures on the Space Station are encouraged. .

Almost 1200 participants and observers from 63 countries and 20 organizations attended the conference. The 239 papers presented were grouped under the following seven main topics: planning and development of nuclear power programmes; technical and economic experience of nuclear power production; the nuclear fuel cycle; nuclear safety experience; advanced systems; international safeguards; international co-operation. The proceedings are published in six volumes. The sixth volume contains a complete Contents of Volume 1 to 5, a List of Participants, Authors and Transliteration Indexes, a Subject Index and an Index of Papers by Number

  2. Operating experience feedback

    International Nuclear Information System (INIS)

    Slovenian Nuclear Safety Administration (SNSA) has developed its own system for tracking, screening and evaluating the operating experiences of the nuclear installations. The SNSA staff regularly tracks the operating experiences throughout the world and screens them on the bases of applicability for the Slovenian nuclear facilities. The operating experiences, which pass the screening, are thoroughly evaluated and also recent operational events in these facilities are taken into account. If needed, more information is gathered to evaluate the conditions of the Slovenian facilities and appropriate corrective actions are considered. The result might be the identification of the need for modification at the licensee, the need for modification of internal procedures in the SNSA or even the proposal for the modification of regulations. Information system helps everybody to track the process of evaluation and proper logging of activities. (author)

  3. Qualitative experiments in psychology

    DEFF Research Database (Denmark)

    Wagoner, Brady

    2015-01-01

    In this article, I explore the meaning of experiments in early twentieth century psychology, focusing on the qualitative experimental methodology of psychologist Frederic BARTLETT. I begin by contextualizing BARTLETT's experiments within the continental research tradition of his time, which was in...... a state of transition from a focus on elements (the concern of psychophysics) to a focus on wholes (the concern of Gestalt psychology). The defining feature of BARTLETT's early experiments is his holistic treatment of human responses, in which the basic unit of analysis is the active person relating...... to some material within the constraints of a social and material context. This manifests itself in a number of methodological principles that contrast with contemporary understandings of experimentation in psychology. The contrast is further explored by reviewing the history of "replications and...

  4. Reactor antineutrino experiments

    Neutrinos are elementary particles in the standard model of particle physics. There are 3 flavors of neutrinos that oscillate among themselves. Their oscillation can be described by a 3$\\times$3 unitary matrix, containing three mixing angles $\\theta_{12}$, $\\theta_{23}$, $\\theta_{13}$, and one CP phase. Both $\\theta_{12}$ and $\\theta_{23}$ are known from previous experiments. $\\theta_{13}$ was unknown just two years ago. The Daya Bay experiment gave the first definitive non-zero value in 2012. An improved measurement of the oscillation amplitude $\\sin^{2}2(\\theta_{13})$ = $0.090^{+0.008}_{-0.009}$ and the first direct measurement of the $\\bar\

  5. Prospects in coincidence experiments

    International Nuclear Information System (INIS)

    During a long time the description of nuclei in terms of nucleons only was a powerful and economical way to understand their structure. However the use of probes of higher and higher energy has forced us to go beyond this simple picture and to deal with two novel aspects of nuclei: short range correlations between two or several nucleons and internal structure of hadrons. This two points are illustrated in this paper; coincidence experiments which can answer the problems opened by this new points are presented. Four typical examples of coincidence experiments induced by virtual photons are given

  6. HOCUS: hole closure experiments

    International Nuclear Information System (INIS)

    The free-fall penetrator is one of the conceptual disposal techniques considered by the Seabed Working Group for the disposal of heat-generating radioactive waste in the deep ocean. However, one aspect of penetrator behaviour that remains unresolved is the degree to which the sediment barrier is disturbed by the penetration event. The HOCUS experiments were therefore devised to measure the properties of the sediment filling the entry pathway of the penetrator. This paper describes the experiments which were performed in the Mediterranean in a water depth of approximately 250 m and used a sea floor platform to probe and core the entry pathways of a number of penetrators.

    The oceans are an equal partner with the atmosphere in the global climate system. The World Ocean Circulation Experiment is presently being implemented to improve ocean models that are useful for climate prediction both by encouraging more model development but more importantly by providing quality data sets that can be used to force or to validate such models. WOCE is the first oceanographic experiment that plans to generate and to use multiparameter global ocean data sets. In order for WOCE to succeed, oceanographers must establish and learn to use more effective methods of assembling, quality controlling, manipulating and distributing oceanographic data.

    In 1977, in a record-time of 9 months, the magnets of the g-2 experiment were modified and used to build a proton/antiproton storage ring: the "Initial Cooling Experiment" (ICE). It served for the verification of the cooling methods to be used for the "Antiproton Project". Stochastic cooling was proven the same year, electron cooling followed later. Also, with ICE the experimental lower limit for the antiproton lifetime was raised by 9 orders of magnitude: from 2 microseconds to 32 hours. For its previous life as g-2 storage ring, see 7405430.

    The hadron calorimeter of the NA49 experiment. NA49 is one of the seven experiments (NA44, NA45, NA49, NA50, NA52, WA97/NA57 and WA98) involved in CERN's Heavy Ion programme, which provided evidence for the existence of a new state of matter, the quark-gluon plasma. In this state, quarks, instead of being bound up into more complex particles such as protons and neutrons, are liberated and roam freely. Theory predicts that this state must have existed at about 10 microseconds after the Big Bang, before the formation of matter as we know it today.

    International Nuclear Information System (INIS)

    This project was undertaken to obtain both experimental data and experience with certain experimental techniques, which were considered necessary for the multilateral Rod Overpressure Experiment (ROPE Project). A BWR segment rod was refilled after base irradiation to give a rod internal pressure in excess of the system pressure. This rod and an identical (but not refilled) reference rod were irradiated in the R2 reactor. The overpressure rod had a clad outward creep of approximately 8 ?m after 20 days irradiation at 30 kW/m, but with an overall reduction in the pellet-clad gap. (author)

The next stage of the oscillation studies should be the observation of a finite $\\sin^{2} 2\\theta_{13}$ . If a non-zero $\\sin^{2} 2\\theta_{13}$ is observed, the subsequent goals should be the observation of the CP violation and the determination sign of $\\Delta m_{23}^{2} . Possible future neutrino oscillation experiments that could assess these questions are discussed.

    Previous deformation experiments in which IR imaging was used pointed to a correlation in between IR signature in areas where heat was expected to be. The surface is not uniform during deformation experiments which cause cracks in the image in areas with increased temperature. To measure temperature under dynamic conditions, simultaneous reflectivity and radiance measurement under events of interest is needed. To measure a temperature measurement, a Reflectance measurement taken by framing camera at the edge of the camera sensitivity (700nm). Allows relative measurement at this wavelength. At reasonable temperatures the spectral radiance should peak near 2u and be 3-4 orders of magnitude higher than at 700 nm.

    The Succinct Solver of Nielson and Seidl is based on the Alternation-free Least Fixed Point Logic and it is implemented in SML using a combination of recursion, continuations, prefix trees and memoisation. It is known that the actual formulation of the analysis has a great impact on the execution time of the solver and the aim of this note is to provide some insight into which formulations are better than others. The experiments addresses three general issues: (i) the order of the parameters of relations, (ii) the order of conjuncts in preconditions and (iii) the use of memoisation. The experiments are performed for Control Flow Analyses for Discretionary Ambients.

  13. Experience and Sustainable Consumption

    DEFF Research Database (Denmark)

    Rasmussen, Tove Arendt

    2014-01-01

    Experience understood as experience-based consumption is by now fairly absent from the research agenda of the different theories on sustainable consumption. On the basis of Colin Campbell’s notion of romantic ethics and emotional sentimentality in modern hedonism, I claim that sustainable consumption may re-enchant ordinary consumption and thereby even become a part of marketing and the experience economy. New layers of meaning are at stake and altruistic motives come into play; doing something good for someone or something, aside from oneself, is a very strong trigger of positive emotions. Very often, however, the actual purchase does not live up to the demands of doing good in the sustainable consumption chain, and the individual might end up with a guilty conscience, which again is a possible trigger for lingering in a sentimental mode of guilt. Emotions of sentimentality may actually convince the individual that she really does care for others and thereby provide a positive experience of feeling good – even if it takes place in the universe of consumption fantasies only.

    1997-01-01

    A series of atmospheric aerosol diffusion experiments combined with lidar detection was conducted to evaluate and calibrate an existing retrieval algorithm for aerosol backscatter lidar systems. The calibration experiments made use of two (almost) identical mini-lidar systems for aerosol cloud detection to test the reproducibility and uncertainty of lidars. Lidar data were obtained from both single-ended and double-ended Lidar configurations. A backstop was introduced in one of the experiments and a new method was developed where information obtained from the backstop can be used in the inversion algorithm. Independent in-situ aerosol plume concentrations were obtained from a simultaneous tracer gas experiment with SF6, and comparisons with the two lidars were made. The study shows that the reproducibility of the lidars is within 15%, including measurements from both sides of a plume. The correspondence with in-situ measurements is excellent. Finally, the new backstop method is able to reveal information which can close the lidar equation by obtaining the relation between backscatter and extinction in an aerosol cloud.

    In the Los Alamos Magnetized Gun Experiment we are attempting to produce a compact torus in a manner similar to an earlier experiment of Alfven. In our experiment a solenoidal coil is placed inside the inner electrode of a coaxial plasma gun. This coil produces an axial magnetic field inside the inner electrode which diverges and becomes a largely radial field in front of the gun muzzle. The idea is that when the gun is fired, the plasma escaping from the gun stretches these radial fields along the axial direction away from the gun, and these field lines can reconnect behind the plasma forming the poloidal field of the compact torus. The magnetic field generated by the gun current becomes the toroidal field and the major axis of the compact torus will be the same as the axis of the coaxial gun. Recent interest in this possible method of compact torus generation was stimulated by C. Hartman, and the approach is also being pursued in the field-reversed plasma gun experiment at LLL

  4. Prospects in coincidence experiments

    International Nuclear Information System (INIS)

    The sensitivity of virtual photons to the local variations of the charge and magnetization densities is exploited to study the short-range part of the nucleon-nucleon interaction inside the nucleus. The possibility of varying energy, squared mass and longitudinal polarization of the photons independently enables us to disentangle the mechanisms related to the internal structure of the nucleon (e.g. quark interchange) and the contribution due to meson exchange. Coincidence experiments of the type (e,e'N) and (e,e'NN) are performed to suppress the meson contribution to the longitudinal part of the quasi-elastic peak. Four typical examples of coincidence experiments induced by virtual photons are discussed: experiments (1) on the spectroscopic structure of the quasi-elastic peak and the problem of deep lying hole states; (2) on the structure of the continuum; (3) on the low energy side of the quasi-elastic peak; and finally a three-arm coincidence experiment.

  5. Self managing experiment resources

    International Nuclear Information System (INIS)

    Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

    The OLYMPUS experiment was designed to measure the ratio between the positron–proton and electron–proton elastic scattering cross-sections, with the goal of determining the contribution of two-photon exchange to the elastic cross-section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, ?{sub p}G{sub E}{sup p}/G{sub M}{sup p}, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01 GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately 25°–75°. Symmetric Møller/Bhabha calorimeters at 1.29° and telescopes of GEM and MWPC detectors at 12° served as luminosity monitors. A total luminosity of approximately 4.5 fb{sup ?1} was collected over two running periods in 2012. This paper provides details on the accelerator, target, detectors, and operation of the experiment.

  13. Experiments on ferrimagnetism

    International Nuclear Information System (INIS)

    Ferrimagnetism undoubtedly deserves a proper place in the undergraduate laboratory on electricity and magnetism. Four student experiments on ferrimagnetism are considered: (i) the hysteresis loops and permeability of a ‘soft’ ferrite; (ii) the differential permeability versus a dc bias; (iii) the frequency dependence of the complex permeability and (iv) the electromagnetic interference suppression by ferrite chokes and beads. Two ferrite cores taken off a low-frequency choke and a power cord are used. The measurements are simple and straightforward and show the important properties of ferrites and their applications. The values of the permeability of the ferrite core determined in experiments (i)–(iii) are in reasonable agreement. The frequency dependence of the complex permeability of the ferrites is similar to that given by the manufacturers. The capability of absorbing electromagnetic waves in a definite frequency range shown in experiment (iv) demonstrates one of the principles of Stealth technology. The equipment necessary for the experiments can be found in many student laboratories. (paper)

    Since 2009, out-of-hospital care of junctional hemorrhage bleeding from the trunk-appendage junctions has changed, in part, due to the newly available junctional tourniquets (JTs) that have been cleared by the US Food and Drug Administration. Given four new models of JT available in 2014, several military services have begun to acquire, train, or even use such JTs in care. The ability of users to be trained in JT use has been observed by multiple instructors. The experience of such instructors has been broad as a group, but their experience as individuals has been neither long nor deep. A gathering into one source of the collective experience of trainers of JT users could permit a collation of useful information to include lessons learned, tips in skill performance, identification of pitfalls of use to avoid, and strategies to optimize user learning. The purpose of the present review is to record the experiences of several medical personnel in their JT training of users to provide a guide for future trainers. PMID:26360350

    The AMY experiment is one of three major experiments at TRISTAN which is studying the states the matter produced in electron positron annihilations in the center of mass energy range of 50--65GeV. It provides information between the lower energy facilities such as PEP and PETRA and the new facilities SLC and LEP which are designed to operate in the region of the Z0 mass near 90GeV. In the region of the AMY experiment, interaction cross sections are near their minimum of about 100pb, making it difficult to acquire large data samples during typical running cycles. This last year has seen an accumulation of about 10---12pb-1 of integrated luminosity in the energy range from 58 to 61.7GeV. Despite this limited data sample, the AMY experiment has been extremely active in attempting to extract the minimum amount of information from the data. Some of the most significant results are discussed in this paper. 9 refs

    The Florida Footprint experiments were a series of field programs in which perfluorocarbon tracers were released in different configurations centered on a flux tower to generate a data set that can be used to test transport and dispersion models. These models are used to determine the sources of the CO{sub 2} that cause the fluxes measured at eddy covariance towers. Experiments were conducted in a managed slash pine forest, 10 km northeast of Gainesville, Florida, in 2002, 2004, and 2006 and in atmospheric conditions that ranged from well mixed, to very stable, including the transition period between convective conditions at midday to stable conditions after sun set. There were a total of 15 experiments. The characteristics of the PFTs, details of sampling and analysis methods, quality control measures, and analytical statistics including confidence limits are presented. Details of the field programs including tracer release rates, tracer source configurations, and configuration of the samplers are discussed. The result of this experiment is a high quality, well documented tracer and meteorological data set that can be used to improve and validate canopy dispersion models.

    The NA48 experiment is designed to study the Charge-Parity (CP) violation. CP violation is observed in certain very rare decays. Its study is important in understanding Nature's preference of matter over antimatter, which resulted in asymmetry soon after the Big Bang, creating a matter-dominated Universe.

  3. The Mobilisatsia experience

    International Nuclear Information System (INIS)

    The hazards of long-duration manned space flight are real. In order to participate effectively in long duration orbital missions or to continue the exploration of space, the health of the astronaut must be secured. There is mounting evidence that changes in the immune response of an astronaut in short-term flights, resemble those occurring after acute stress, while the changes during long-term flights resemble those caused by chronic stress. This blunting of the immune system occurs concomitant with a relative increase in microbial contamination in the space cabin environment. Such a combination of events results in an increased probability of in-flight infectious events. Micro-organisms are subject to a genetic evolution, which may lead to the capacity to colonize new environments and to cause infections. Central players in this evolutionary process are mobile genetic elements. They help to mobilize and reorganize genes, be it within a given genome (intragenomic mobility) or between bacterial cells (intercellular mobility). Hence, the processes of genetic exchange can mobilize genetic elements between bacterial strains, and therefore play a role in determining the infectious potential. The specific confined environment and space-flight related factors (such as microgravity and cosmic radiation) may increase the frequency in which mobile genetic elements are exchanged between micro organisms. The aim of the Mobilisatsia experiment was to promote microbial gene transfer under space flight conditions during a short-term experiment conducted aboard the International Space Station (ISS). The efficiency of the gene exchange process was compared with a synchronously performed ground control experiment. An experiment was carried out with well-characterized Gram-negative reference strains and one experiment was done with Gram-positive reference strains

  4. Transformations of emotional experience.

    de Cortiñas, Lia Pistiner

    2013-06-01

    In this paper the author approaches mental pain and the problems in a psychoanalytic treatment of patients with difficulties in the psychic transformation of their emotional experiences. The author is interested in the symbolic failure related to the obstruction of development of phantasies, dreams, dream-thoughts, etc. She differentiates symbolization disturbances related to hypertrophic projective identification from a detention of these primitive communications and emotional isolation. She puts forward the conjecture that one factor in the arrest of this development is the detention of projective identifications and that, when this primitive means of communication is re-established in a container-contained relationship of mutual benefit, this initiates the development of a symbolization process that can replace the pathological 'protection'. Another hypothesis she develops is that of inaccessible caesuras that, associated with the detention of projective identification, obstruct any integrative or interactive movement. This caesura and the detention of projective identifications affect mental functions needed for dealing with mental pain. The personality is left with precarious mental equipment for transforming emotional experiences. How can a psychoanalytical process stimulate the development of creative symbolization, transforming the emotional experiences and leading towards mental growth? The author approaches the clinical problem with the metaphor of the psychic birth of emotional experience. The modulation of mental pain in a container-contained relationship is a central problem for the development of the human mind. For discovering and giving a meaning to emotional experience, the infant depends on reverie, a function necessary in order to develop an evolved consciousness capable of being aware, which is different from the rudimentary consciousness that perceives but does not understand. The development of mature mental equipment is associated with the personality's attitude towards mental pain. The differentiation between psychotic, neurotic or autistic functioning depends on what defences are erected to avoid mental pain. The primary link between infant and mother is where the building of mental equipment takes place, through communicational forms that, to begin with, are not verbal. The author suggests the need for the development of an ideo-grammar (in gestures, paralinguistic forms, etc.) in primary relations, as the precursor forms that will become the matrix for the mental tools for dealing with emotional experiences in a mature way. The paper stresses the significance of the parental containing function for the development of symbolization of prenatal emotional experiences. This containment develops ideograms, transformations of sense impressions into proto-symbols, instruments that attenuate the traumatic experiences of helplessness. The author takes Bion's ideas about extending the notion of dream-work to an alpha function that goes on continually, day and night, transforming raw emotional experiences in a 'dream'. In order to acquire a meaning, facts need to be 'dreamed' in this extended sense. Meaning and truth are the nurture of the mind. Mental growth, the development of adequate tools--including reverie--for dealing with mental pain, seen from a psychoanalytic perspective including reverie, implies that the object becomes a provider of meanings. Analysis begins to aim primarily at the generation or expansion of the mental container, instead of predominantly working on unconscious contents as such. PMID:23781834

  5. Hydrothermal organic synthesis experiments

    Shock, Everett L.

    1992-01-01

    The serious scientific debate about spontaneous generation which raged for centuries reached a climax in the nineteenth century with the work of Spallanzani, Schwann, Tyndall, and Pasteur. These investigators demonstrated that spontaneous generation from dead organic matter does not occur. Although no aspects of these experiments addressed the issue of whether organic compounds could be synthesized abiotically, the impact of the experiments was great enough to cause many investigators to assume that life and its organic compounds were somehow fundamentally different than inorganic compounds. Meanwhile, other nineteenth-century investigators were showing that organic compounds could indeed be synthesized from inorganic compounds. In 1828 Friedrich Wohler synthesized urea in an attempt to form ammonium cyanate by heating a solution containing ammonia and cyanic acid. This experiment is generally recognized to be the first to bridge the artificial gap between organic and inorganic chemistry, but it also showed the usefulness of heat in organic synthesis. Not only does an increase in temperature enhance the rate of urea synthesis, but Walker and Hambly showed that equilibrium between urea and ammonium cyanate was attainable and reversible at 100 C. Wohler's synthesis of urea, and subsequent syntheses of organic compounds from inorganic compounds over the next several decades dealt serious blows to the 'vital force' concept which held that: (1) organic compounds owe their formation to the action of a special force in living organisms; and (2) forces which determine the behavior of inorganic compounds play no part in living systems. Nevertheless, such progress was overshadowed by Pasteur's refutation of spontaneous generation which nearly extinguished experimental investigations into the origins of life for several decades. Vitalism was dealt a deadly blow in the 1950's with Miller's famous spark-discharge experiments which were undertaken in the framework of the Oparin and Haldane hypotheses concerning the origin of life. These hypotheses were constructed on some basic assumptions which included a reduced atmosphere, and a low surface temperature for the early Earth. These ideas meshed well with the prevailing hypothesis of the 1940's and 50's that the Earth had formed through heterogeneous accretion of dust from a condensing solar nebula. Miller's experiments were extremely successful, and were followed by numerous other experiments by various investigators who employed a wide variety of energy sources for abiotic synthesis including spark discharges, ultra-violet radiation, heat, shock waves, plasmas, gamma rays, and other forms of energy. The conclusion reached from this body of work is that energy inputs can drive organic synthesis from a variety of inorganic starting materials.

    2015-01-01

    Data analysis in fundamental sciences nowadays is an essential process that pushes frontiers of our knowledge and leads to new discoveries. At the same time we can see that complexity of those analyses increases fast due to a)~enormous volumes of datasets being analyzed, b)~variety of techniques and algorithms one have to check inside a single analysis, c)~distributed nature of research teams that requires special communication media for knowledge and information exchange between individual researchers. There is a lot of resemblance between techniques and problems arising in the areas of industrial information retrieval and particle physics. To address those problems we propose Reproducible Experiment Platform (REP), a software infrastructure to support collaborative ecosystem for computational science. It is a Python based solution for research teams that allows running computational experiments on shared datasets, obtaining repeatable results, and consistent comparisons of the obtained results. We present s...

    This paper investigates how early internationalization is impacted by certain pre-founding innovation activities of an academic spin-off’s team. Framed in the imprinting, experiential knowledge and network literatures, we combine and assess patent analysis with survey data. Our findings link the...... founding teams’ pre-foundation R&D and customer collaborations to early exports. We also show that pre-foundation involvement in these various forms of collaboration, as well as a diverse stock of prior technical knowledge, can compensate for a lack of business experience in the team. The results also show...... that prior business experience does not predict very early export (within three years). Our results offer fresh insight to the international business and international entrepreneurship literatures, and implications for policy development. In particular, international R&D collaborations at public...

  9. Electrohydrodynamic heat pipe experiments

    Jones, T. B.; Perry, M. P.

    1974-01-01

    Experiments with two electrohydrodynamic heat pipes are reported. Both devices employ an electromechanical flow structure for axial liquid flow and a capillary wicking structure for (1) collection of condensed liquid at the cooled end and (2) distribution of this liquid at the heated end. One device has circumferential grooving for the capillary structure and the other has feltmetal wicking. The experiments successfully demonstrate the electrohydrodynamic heat pipe concept. Compatibility of the two circumferential wick structures with an axial electromechanical flow structure is also demonstrated. A significant mismatch of the capillary groove and electrohydrodynamic pumping capabilities results in severe hydrodynamic burn-out limiting in the first heat pipe. Both devices have very poor over-all thermal conductances of the order of 1-2 W/deg C, reflecting the generally poor heat-transfer properties of the dielectric working fluids required in electrohydrodynamic heat pipes.

  10. Microwave Tokamak Experiment

    International Nuclear Information System (INIS)

    The Microwave Tokamak Experiment, now under construction at the Laboratory, will use microwave heating from a free-electron laser. The intense microwave pulses will be injected into the tokamak to realize several goals, including a demonstration of the effects of localized heat deposition within magnetically confined plasma, a better understanding of energy confinement in tokamaks, and use of the new free-electron laser technology for plasma heating. The experiment, soon to be operational, provides an opportunity to study dense plasmas heated by powers unprecedented in the electron-cyclotron frequency range required by the especially high magnetic fields used with the MTX and needed for reactors. 1 references, 5 figures, 3 tables

  11. New Experiments with Antiprotons

    International Nuclear Information System (INIS)

    Fermilab operates the world's most intense antiproton source. Newly proposed experiments can use those antiprotons either parasitically during Tevatron Collider running or after the Tevatron Collider finishes in about 2011. For example, the annihilation of 8 GeV antiprotons might make the world's most intense source of tagged D0 mesons, and thus the best near-term opportunity to study charm mixing and, via CP violation, to search for new physics. Other precision measurements that could be made include properties of the X(3872) and the charmonium system. An experiment using a Penning trap and an atom interferometer could make the world's first measurement of the gravitational force on antimatter. These and other potential measurements using antiprotons could lead to a broad physics program at Fermilab in the post-Tevatron era. (author)

    Wang, Yi-Ming

    2015-06-01

    A minimal energy implosion-scaling model was recently developed to characterize the physical properties of the hot spot in terms of the peak implosion energy. In this model, the hot spot energy, volume, pressure, mass and areal density at the stagnation time are uniquely determined by the peak implosion velocity, the equation of state and the adiabat of the pusher and the DT fuel (cold and hot) at the peak implosion time. In this work, we apply this model to a number of published low-foot and high-foot experiments performed at the National Ignition Facility. Our model analysis is in a good agreement with the experimental data when a high adiabat is assumed for both low and high foot experiments. Implications of the results are discussed. This work was performed under the auspices of the U.S. Department of Energy by the Los Alamos National Laboratory under Contract No. W-7405-ENG-36.

    The NEMO-3 (Neutrino Ettore Majorana Observatory) experiment, located in the Modane Underground Laboratory, is currently searching for neutrinoless double beta decay (0{nu}{beta}{beta}). The experiment has been taking data since 2003 with seven double beta isotopes and is scheduled to complete data acquisition in late 2010. Two neutrino double beta decay (2{nu}{beta}{beta}) results for the main isotopes (7 kg of {sup 100}Mo and 1 kg of {sup 82}Se), new results for {sup 150}Nd, as well as results for {sup 96}Zr, {sup 48}Ca, {sup 130}Te and {sup 116}Cd are presented. NEMO-3 uses a unique technique that allows for the in situ measurement of background contamination. No evidence for neutrinoless double beta decay has been found to date. The data are also interpreted in terms of alternative models such as weak right-handed currents and Majoron emission.

Independent in-situ aerosol plume concentrations were obtained from a simultaneous tracer gas experiment with SF6, and comparisons with the two lidars were made. The study shows that the reproducibility of the lidars is within 15%, including measurements from both sides of a plume. The...... correspondence with in-situ measurements is excellent. Finally, the new backstop method is able to reveal information which can close the lidar equation by obtaining the relation between backscatter and extinction in an aerosol cloud....

  16. LASL fast liner experiment

    International Nuclear Information System (INIS)

    The LASL Fast Liner Experiment explores a fusion concept in which a prepared plasma is adiabatically compressed to thermonuclear temperatures and densities by a rapidly imploding solid metal liner. A prepared plasma having ? > 1 is in contact with the liner and end plugs, and contains an embedded magnetic field to inhibit thermal conduction. Cylindrical liners are magnetically imploded by a large axial current carried in the liner shell. Theoretical estimates indicate an implosion velocity of at least 106 cm/s is necessary for this geometry if the plasma heating rate is to be greater than the cross-field thermal conduction loss rate. Experimental work to develop this concept involves attempts to provide a suitable preplasma for liner implosions as well as studies of magnetically driven liner implosions. In the plasma preparation experiments a coaxial plasma gun was used to inject plasma into a simulated liner geometry

    The tracking detector for the LAT science instrument on the GLAST mission is an example of a large-scale particle detection system built primarily by particle physicists for space flight within the context of a NASA program. The design and fabrication model in most ways reflected practice and experience from particle physics, but the quality assurance aspects were guided by NASA. Similarly, most of the electronics in the LAT as a whole were designed and built by staff at a particle physics lab. This paper reports on many of the challenges and lessons learned in the experience of designing and building the tracking detector and general LAT electronics for use in the NASA GLAST mission.

  18. The ECHo experiment

    International Nuclear Information System (INIS)

    The determination of the absolute scale of the neutrino masses is one of the most challenging questions in particle physics. Different approaches are followed to achieve a sensitivity on neutrino masses in the sub-eV range. Among them, experiments exploring the beta decay and electron capture processes of suitable nuclides can provide necessary information on the electron neutrino mass value. In this talk we present the Electron Capture 163Ho experiment ECHo, which aims to investigate the electron neutrino mass in the sub-eV range by means of the analysis of the calorimetrically measured energy spectrum following the electron capture process of 163Ho. A high precision and high statistics spectrum is measured by means of low temperature magnetic calorimeter arrays. We present preliminary results obtained with a first prototype of single channel detectors as well as the participating groups and their on-going developments.

  20. Review of CHS experiments

    International Nuclear Information System (INIS)

    Review of recent experimental efforts is presented on CHS plasma with the low aspect ratio. MHD characteristics is discussed from viewpoint of Shafranov shift, where NBI beam pressure plays an important role in the equilibrium pressure at the low density of 13cm-3. Compensation of large Shafranov shift by the pre-programmed vertical field control is shown to be effective to obtain high ? plasma in the low Ap configuration. Local transport analysis has been extensively done for NBI and ECH plasmas. Effect of the radial electric field and the magnetic well on the transport is discussed. Dependence of the NBI deposited power on the magnetic axis position is also discussed. Recent experiments include perturbation field effect on the transport, and damping mechanism of the toroidal plasma rotation, which are interesting from helical plasma physics. Preliminary ICRF heating experiment gives a promising result. (author). 8 refs, 7 figs

    The objectives of the vibration isolation technology experiment are to demonstrate the viability of the magnetic suspension technology in providing the isolation of large structures elements from the external environment and to quantify the degree of isolation provided by this system. The approach proposed for this experiment is to mount a six-degrees-of-freedom magnetic bearing suspension system at the free end of a shuttle-attached flexible structure such as MAST. The disturbance generator, located on top of the isolation system, will be energized at selected and broadband frequencies to simulate a typical spacecraft vibration environment. Sensors located on the isolation system and the flexible structures element will be used to quantify the degree of isolation provided by this system.

This model conversion uses the Hidden Markov Models(HMM classification procedure. The first step consists of theiterative mapping of French models to Czech ones. The mapping is givenby the analysis the confusion matrix. The second step is the Baum-Welchre-estimation resulting in the final models for Czech language. Despiteof the differences between French and Czech languages the finalrecognition score reaches 64% for the phoneme recognition and 74% fordigit recognition. Relatively low recognition accuracy is caused by theinadequate noise model. The experiences gained with the cross-languageexperiment were utilized for the classification of simple human bodymovements. The solution of this problem and results are described inthe second part of this contribution under the title EEG SignalsClassification-Introduction to the Problem.

    Gyroscopes in motion about a massive body are found to have two main effects: (1) geodetic effect, solely due to motion of the gyroscope about the earth and (2) motional effect, due to earth rotation. An experiment is proposed to measure the precession rate of one or more gyroscopes, mounted either on earth or in a satellite, with respect to the axis of a telescope pointing at a suitable fixed star. The procedures and apparatus to be used in this experiment are outlined; the error analysis is summarized.

    The Shooting Star Experiment (SSE) is designed to develop and demonstrate the technology required to focus the sun's energy and use the energy for inexpensive space Propulsion Research. Pictured is an engineering model (Pathfinder III) of the Shooting Star Experiment (SSE). This model was used to test and characterize the motion and deformation of the structure caused by thermal effects. In this photograph, alignment targets are being placed on the engineering model so that a theodolite (alignment telescope) could be used to accurately measure the deformation and deflections of the engineering model under extreme conditions, such as the coldness of deep space and the hotness of the sun as well as vacuum. This thermal vacuum test was performed at the X-Ray Calibration Facility because of the size of the test article and the capabilities of the facility to simulate in-orbit conditions

  8. Preliminary experience with mammography

    International Nuclear Information System (INIS)

    Radiologists with very limited practical experience in mammography initially achieved a low PVsub(pos) (0.50) and a high PVsub(neg) (0.95) in blind mammography of 80 patients with 85 excised and histologically examined breast tumours. After having read films from approximately 2500 patients the initial films were blindly reevaluated. PVsub(neg) was unchanged, whereas PVsub(pos) was elevated significantly (0.80). The intraobserver variation was 11.5 per cent. The actual interobserver variation was 3.2 per cent. These findings indicate that the reliability of blind mammography in patients with palpable tumours of the breast is considerable, also in case of only limited mammographic experience. (orig.)

  9. Fast critical experiments

    International Nuclear Information System (INIS)

    A review of fast-neutron critical experiments is presented. The history of the assemblies falls into three overlapping phases. The first, beginning in 1948, relates to simple, compact metal assemblies with extremely high-energy neutron spectra. Examples given of this type of assembly, with critical specifications, spectral indexes, and reactivity calibration are LADY GODIVA, FLATTOP, JEZEBEL and U(16). Details are also given for early experiments with TOPSY. The second phase, starting 6 years later, covers larger, more diffuse assemblies that are still simply describable because of uniform core and reflector regions. Descriptions, spectral indices and reactivity coefficients are given for Big Ten, ZPR-3, ZPR-6, VERA, FR0, ZEBRA and SNEAK assemblies. These two categories encompass the so-called benchmark assemblies. The final phase, not discussed, started in 1955 and applies to engineering mock-ups of fast reactors. (U.K.)

    The CMS experiment is getting ready to take data at the LHC accelerator at CERN. Due to late delivery of the experimental caverns the detector had to be pre-assembled on the surface and lowered in large segments. This has constrained the commissioning strategy of the experiment. Global commissioning has started in Spring of 2007 and has progressed in parallel with the construction and assembly of detector and services underground. This paper describes the strategy adopted in order to commission components of the system in incremental steps in order to be ready to accept collisions from LHC with a well debugged and understood system, including the detector, acquisition system, trigger, software, computing and data shipping.

  14. Framatome's gadolinium experience

    International Nuclear Information System (INIS)

    The burnable poison used by Framatome is gadolinium oxide integrated in the pellet by blending with UO2. This is the integrated poison which provides the largest experience feedback worldwide. It has been used in BWRs for 30 years to attenuate the power peaking in the assemblies of these reactors ana in PWRs since the eighties, when optimized annual managements or extended cycles were first introduced. Framatome's experience feedback is extensive. Framatome loaded its first gadolinium-poisoned assemblies in 1978. By beginning of 1998 (March 1st), the total number of gadolinium rods loaded into cores reached 18000 representing 1900 gadolinium fuel assemblies in 82 reloads, 34 different reactors (approximately 200 cycles x reactor). This experience covers a wide spectrum of designs: . Gadolinium content varying from 2 to 10%. . Number of gadolinium rods per poisoned assembly varying from 4 to 16, . Gadolinium rod position peripheral or dispersed (in the centre of the assembly), . Matrix made of depleted, natural or enriched UO2 (up to 4.19% U235), . Rods with or without truncations, . Cycle length varying between 240 and 690 EFPD, . Managements with different hybridity levels from OUT-IN to IN-OUT, To date, the core physics codes used are perfectly qualified. The many core physics tests run in experimental reactors (Cameleon and Gedeon programmes) and the operational experience feedback was have led to validation of the predictive calculation. The gadolinium bearing assemblies loaded by Framatome have experienced burnups up to 48 GWd/tU and no safety related events has been noticed due to gadolinium. (Author)

  6. Scaling of containment experiments

    International Nuclear Information System (INIS)

    The paper summarises results of the SCACEX (SCAling of Containment EXperiments) multi-partner project in the EURATOM 5th Framework Programme, which was aimed to establish a collection of scaling analyses for laboratory experiments related to nuclear reactor containment safety investigations. Scaling analysis is necessary in many cases where results from downscaled experiments are to be transferred to large-scale reactor conditions. Beginning with a brief overview of the theoretical basis and methodology of scaling and similarity analysis, the topics and main results of several scaling studies are presented, covering such diverse fields like turbulent and radiative heat transfer, steam condensation and evaporation, spray system dynamics, blowdown phenomena in a bubbler condenser containment, atmospheric natural convection flow, cable ageing, performance of sealing materials, cracks in concrete walls, and behaviour of steel structures under dynamic loads. The analyses demonstrate that the existing methods of scaling and similarity analysis have an almost universal range of applicability. They require a good knowledge of the phenomena associated with the individual experiments, which is conveniently documented in a simplified Phenomena Identification and Ranking Table (PIRT). Several ways to establish dimensionless numbers were taken, and it was found that this can be a more challenging task where no straight-forward recipes are available, especially in areas where scaling methods are not well established. The public final SCACEX project report is intended to serve as a reference for future scaling analyses in similar applications. Common steps or features of scaling in different application fields turn out as follows: Identification and ranking of relevant phenomena (simplified PIRT), list of relevant parameters associated with the phenomena, list of dimensionless numbers derived from the relevant parameters, interpretation taking into account the geometric (or time-related) scale ratios

  8. NPB Cesium Space Experiment

    1992-01-01

    Neutral Particle Beam (NPB) weapons systems are planned to perform the ballistic missile defense functions of nuclear weapon/decoy discrimination and warhead kill at appropriate energy levels and ion currents. Negatively charged ions are produced in a specialized ion source and focused into a high quality particle beam. NPB linear accelerators accelerate and steer the negatively charged ions using electric and magnetic fields. After acceleration and steering the neutralizer system strips away extra electrons from ions to form the electrically neutral particle beam. The neutral beam then travels through space to the target unaffected by the Earth's magnetic fields. Continuing technological advances have greatly reduced the size and weight of NPB accelerator systems. Ion current production has been enhanced by over 100 percent with the intermittent addition of cesium at the NPB ion source device. This increase in current is essential to attain the most light weight, compact NPB platforms and minimize expensive launch costs. Addition of cesium into the ion source has been identified by the NPB community as the highest priority risk reduction space experiment necessary prior to planned NPB accelerator experiments and later weapons systems. The NPB Cesium Space Experiment is planned to successfully demonstrate controlled cesium introduction and vaporization into a simulated ion source chamber. Microgravity effects on the cesium deposition will be studied as will the effects of small amounts of cesium on high voltage accelerator components that might be susceptible to electrical insulator break downs. The experiment design will simulate as closely as possible the environment, physical and operational characteristics of the actual NPB ion source.

  11. The Vinca dosimetry experiment

    International Nuclear Information System (INIS)

    On 15 October 1958 there occurred a very brief uncontrolled run of the zero-power reactor at the Boris Kidric Institute of Nuclear Science, Vinca, near Belgrade, Yugoslavia. During this run six persons received various doses of radiation. They were subsequently given medical treatment of a novel kind at the Curie Hospital, Paris. In atomic energy operations to date, very few accidents involving excessive radiation exposure to human beings have occurred. In fact, the cases of acute radiation injury are limited to about 30 known high exposures, few of which were in the lethal or near-lethal range. Since direct experiment to determine the effects of ionizing radiation on man is unacceptable, information on these effects has to be based on a consideration of data relating to accidental exposures, viewed in the light of the much more extensive data obtained from experiments on animals. Therefore, any direct information on the effects of radiation on humans is very valuable. The international dosimetry project described in this report was carried out at Vinca, Yugoslavia, under the auspices of the International Atomic Energy Agency to determine the precise amount of radiation to which the persons had been exposed during the accident. These dosimetry data, together with the record of the carefully observed clinical effects, are of importance both for the scientific study of radiation effects on man and for the development of methods of therapy. The experiment and measurements were carried out at the end of April 1960. The project formed part of the Agency's research programme in the field of health and safety. The results of the experiment are made available through this report to all Member States

    An experiment, proposed by Karl Popper, is considered by many, to be a crucial test of quantum mechanics. While many loop holes have been pointed out in the original proposal, it turned out that they are not crucial to the test. We point out what is fundamentally wrong with the proposal. Using just the standard interpretation of quantum mechanics, we demonstrate that Popper's basic premise was faulty.

An antiproton annihilates a proton in the nucleus of a cancer cell, producing a pair of gamma rays, destroying the entire cell and some surrounding cells. Many fewer antiprotons are required in this treatment than in the equivalent proton hadron therapy, so there is less risk of healthy tissue damage.

    Data analysis in fundamental sciences nowadays is an essential process that pushes frontiers of our knowledge and leads to new discoveries. At the same time we can see that complexity of those analyses increases fast due to a) enormous volumes of datasets being analyzed, b) variety of techniques and algorithms one have to check inside a single analysis, c) distributed nature of research teams that requires special communication media for knowledge and information exchange between individual researchers. There is a lot of resemblance between techniques and problems arising in the areas of industrial information retrieval and particle physics. To address those problems we propose Reproducible Experiment Platform (REP), a software infrastructure to support collaborative ecosystem for computational science. It is a Python based solution for research teams that allows running computational experiments on shared datasets, obtaining repeatable results, and consistent comparisons of the obtained results. We present some key features of REP based on case studies which include trigger optimization and physics analysis studies at the LHCb experiment.

  1. Combined array experiment design

    International Nuclear Information System (INIS)

    Experiment plans formed by combining two or more designs, such as orthogonal arrays primarily with 2- and 3-level factors, creating multi-level arrays with subsets of different strength are proposed for computer experiments to conduct sensitivity analysis. Specific illustrations are designs for 5-level factors with fewer runs than generally required for 5-level orthogonal arrays of strength 2 or more. At least 5 levels for each input are desired to allow for runs at a nominal value, 2-values either side of nominal but within a normal, anticipated range, and two, more extreme values either side of nominal. This number of levels allows for a broader range of input combinations to test the input combinations where a simulation code operates. Five-level factors also allow the possibility of up to fourth-order polynomial models for fitting simulation results, at least in one dimension. By having subsets of runs with more than strength 2, interaction effects may also be considered. The resulting designs have a 'checker-board' pattern in lower-dimensional projections, in contrast to grid projection that occurs with orthogonal arrays. Space-filling properties are also considered as a basis for experiment design assessment

  2. Critical experiment data archiving

    International Nuclear Information System (INIS)

    Critical experiment facilities produced a large number of important data during the past 45 years; however, many useful data remain unpublished. The unpublished material exists in the form of experimenters' logbooks, notes, photographs, material descriptions, etc., This data could be important for computer code validation, understanding the physics of criticality, facility design, or for setting process limits. In the past, criticality specialists have been able to obtain unpublished details by direct contact with the experimenters. Obviously, this will not be possible indefinitely. Most of the US critical experiment facilities are now closed, and the experimenters are moving to other jobs, retiring, or otherwise becoming unavailable for this informal assistance. Also, the records are in danger of being discarded or lost during facility closures, cleanup activities, or in storage. A project was begun in 1989 to ensure that important unpublished data from critical experiment facilities in the United States are archived and made available as a resource of the US Department of Energy's (DOE's) Nuclear Criticality Information System (NCIS). The objective of this paper is to summarize the project accomplishments to date and bring these activities to the attention of those who might be aware of the location of source information needed for archiving and could assist in getting the materials included in the archive

  3. Experiments with polarized antiprotons

    International Nuclear Information System (INIS)

    Though there is a model by R.A. Bryan and R.J.N. Phillips (B-P model) as the one describing proton-antiproton two body scattering and total cross section in low energy region, this model satisfies only a part of the experimental results on the films taken with the CERN 80 cm hydrogen bubble chamber, but does not satisfy the remainder. Tokyo group investigated such B-P model, and was able to obtain the result well explaining the experimental results by adjusting the ?-N coupling constant. The group has also investigated the possibility on polarized antiproton beam. If the polarized antiproton beam can be realized, the systematic research on baryon-antibaryon system may be advanced through the large variety of experiments in this field by injecting the polarized beam into a bubble chamber. Carbon is a very good polarizer in proton-carbon scattering. If carbon shows the similar polarizing power in antiproton-carbon scattering to that, the polarized anti-proton beam may be realized. Therefore the experiments to measure anti-proton polarization has been examined. Finally, the future prospect for antiproton-carbon scattering experiments in the National Laboratory for High Energy Physics is described. (Wakatsuki, Y.)

    The QUIJOTE (Q-U-I JOint Tenerife) CMB Experiment is observing the polarization of the Cosmic Microwave Background and other Galactic and extragalactic signals at medium and large angular scales in the frequency range of 10-40 GHz. This experiment will provide valuable information about the polarization properties of synchrotron and anomalous microwave emission at these frequencies. The maps obtained with the multi-frequency instrument (10-20 GHz), in combination with data from other experiments like Planck and the VLA, will be used to clean the diffuse and compact foreground emission at 30 and 40 GHz, the cosmological channels. After three years of effective observations we expect to reach the required sensitivity to detect a primordial gravitational-wave component if the tensor-to-scalar ratio is larger than r = 0.05. At the moment we have completed the Wide Survey with the multi-frequency instrument, covering 20.000 square degrees of the Northern hemisphere. In addition, we have deep integrations of our main calibrators Taurus A, Cassiopea A, Jupiter and of the Perseus molecular complex region, where we have measured the spectrum of the anomalous microwave emission. We also have observed several regions of interest for our science program where we plan to study the compact and diffuse polarized emission.

    2015-04-01

    Our experiments were involving inductive magnetic levitation. A Halbach array is a system in which a series of magnets is arranged in a manner such that the magnetic field is cancelled on one side of the array while strengthening the field on the other. We constructed two circular Halbach wheels, making the strong magnetic field on the outer rim of the ring. Such system is usually dubbed as an Electrodynamic Wheel (EDW). Rotating this wheel around a horizontal axis above a flat conducting surface should induce eddy currents in said surface through the variable magnetic flux. The eddy currents produce, in turn, their own magnetic fields which interact with the magnets of the EDW. We demonstrated that these interactions produce both drag and lift forces on the EDW which can theoretically be used for lift and propulsion of the EDW. The focus of our experiments is determining how to maximize the lift-to-drag ratio by the proper choice of the induction element. We will also describe our experiments with a rotating circular Halbach array having the strong magnetic field of about 1 T on the flat side of the ring, and acting as a hovercraft.

    The OLYMPUS experiment was designed to measure the ratio between the positron-proton and electron-proton elastic scattering cross sections, with the goal of determining the contribution of two-photon exchange to the elastic cross section. Two-photon exchange might resolve the discrepancy between measurements of the proton form factor ratio, $\\mu_p G^p_E/G^p_M$, made using polarization techniques and those made in unpolarized experiments. OLYMPUS operated on the DORIS storage ring at DESY, alternating between 2.01~GeV electron and positron beams incident on an internal hydrogen gas target. The experiment used a toroidal magnetic spectrometer instrumented with drift chambers and time-of-flight detectors to measure rates for elastic scattering over the polar angular range of approximately $25^\\circ$--$75^\\circ$. Symmetric M{\\o}ller/Bhabha calorimeters at $1.29^\\circ$ and telescopes of GEM and MWPC detectors at $12^\\circ$ served as luminosity monitors.

    In April 2000, three nurses from Chesterfield (UK) were successful in an application for a travel scholarship. The scholarship was to examine emergency nurse practitioner (ENP) schemes in Boston USA after completion of my dissertation based on the same subject, in the course of which the broad span of ENP work had become obvious to me. Leading up to the trip overseas, we discussed specific objectives we hoped to meet but we did not expect the range of experiences we were exposed to within this busy city. It became apparent while in Boston, that we should avoid becoming too focused otherwise we might miss valuable information or experiences which would benefit practice back in the UK. Six of the most striking issues, which impressed all three of us, are covered in this paper. These are then reflected back to UK practice in an attempt to discover whether these experiences can benefit our own profession. Subjects covered include: student training; ENP training and role parameters; physician assistants; primary care and the effect of information technology on the emergency care culture. PMID:11760629

  9. The epithermal critical experiments

    International Nuclear Information System (INIS)

    The epithermal critical experiments. The present phase of the advanced-epithermal-thorium-reactor programme consists of integral-reactor-physic s experiments designed to provide neutron-cross-section information in the 10-MeV to 1-keV range. A series of nine, multi-region, slow-fast, pseudospherica l critical assemblies of the honey- comb, split-table type are being studied. So far, three assemblies have' been run. The outer driver-decouple r region drives an interior U233-Th fuelled spherical test region whose neutron-flux spectrum is successively degraded by increasing the graphite moderator to fuel ratio. A square-wave oscillator experiment defines the central reactivity worths of forty small samples of different materials to 10-8 ?k for each assembly. Additionally, intercalibrated artificial neutron sources are oscillated to determine the various central neutron importance functions. The spectra are obtained by fission-counter measurements with calibrated foils of different thresholds and by a Li6-solid-state- counter sandwich spectrometer. A digital computer routine will be used to compile all measurements into a self-consistent library of spectrum averaged cross-sections. (author)

  17. 2169 steel waveform experiments.

    Energy Technology Data Exchange (ETDEWEB)

    Furnish, Michael David; Alexander, C. Scott; Reinhart, William Dodd; Brown, Justin L.

    2012-11-01

    In support of LLNL efforts to develop multiscale models of a variety of materials, we have performed a set of eight gas gun impact experiments on 2169 steel (21% Cr, 6% Ni, 9% Mn, balance predominantly Fe). These experiments provided carefully controlled shock, reshock and release velocimetry data, with initial shock stresses ranging from 10 to 50 GPa (particle velocities from 0.25 to 1.05 km/s). Both windowed and free-surface measurements were included in this experiment set to increase the utility of the data set, as were samples ranging in thickness from 1 to 5 mm. Target physical phenomena included the elastic/plastic transition (Hugoniot elastic limit), the Hugoniot, any phase transition phenomena, and the release path (windowed and free-surface). The Hugoniot was found to be nearly linear, with no indications of the Fe - phase transition. Releases were non-hysteretic, and relatively consistent between 3- and 5-mm-thick samples (the 3 mm samples giving slightly lower wavespeeds on release). Reshock tests with explosively welded impactors produced clean results; those with glue bonds showed transient releases prior to the arrival of the reshock, reducing their usefulness for deriving strength information. The free-surface samples, which were steps on a single piece of steel, showed lower wavespeeds for thin (1 mm) samples than for thicker (2 or 4 mm) samples. A configuration used for the last three shots allows release information to be determined from these free surface samples. The sample strength appears to increase with stress from ~1 GPa to ~ 3 GPa over this range, consistent with other recent work but about 40% above the Steinberg model.

    The Moon is, together with the Sun, the very first astronomical object that we experience in our life. As this is an exclusively visual experience, people with visual impairments need a different mode to experience it too. This statement is especially true when events, such as more and more frequent public observations of sky, take place. This is the reason why we are preparing a special package for visual impaired people containing three brand new items: 1. a tactile 3D Moon sphere in Braille with its paper key in Braille. To produce it we used imaging data obtained by NASA's mission Clementine, along with free image processing and 3D rendering software. In order to build the 3D small scale model funding by Europlanet and the Italian Ministry for Research have been used. 2. a multilingual web site for visually impaired users of all ages, on basic astronomy together with an indepth box about the Moon; 3. a book in Braille with the same content of the Web site mentioned above. All the items will be developed with the collaboration of visually impaired people that will check each step of the project and support their comments and criticism to improve it. We are going to test this package during the next International Observe the Moon Night event. After a first testing phase we'll collect all the feedback data in order to give an effective form to the package. Finally the Moon package could be delivered to all those who will demand it for outreach or educational goals.

  20. Situating Emotional Experience

    Directory of Open Access Journals (Sweden)

    Christine D Wilson-Mendenhall

    2013-11-01

    Full Text Available Psychological construction approaches to emotion suggest that emotional experience is situated and dynamic. Fear, for example, is typically studied in a physical danger context (e.g., threatening snake, but in the real world, it often occurs in social contexts, especially those involving social evaluation (e.g., public speaking. Understanding situated emotional experience is critical because adaptive responding is guided by situational context (e.g., inferring the intention of another in a social evaluation situation vs. monitoring the environment in a physical danger situation. In an fMRI study, we assessed situated emotional experience using a newly developed paradigm in which participants vividly imagine different scenarios from a first-person perspective, in this case scenarios involving either social evaluation or physical danger. We hypothesized that distributed neural patterns would underlie immersion in social evaluation and physical danger situations, with shared activity patterns across both situations in multimodal sensory regions and in circuitry involved in integrating salient sensory information, and with unique activity patterns for each situation type in coordinated large-scale networks that reflect situated responding. More specifically, we predicted that networks underlying the social inference and mentalizing involved in responding to a social threat (in regions that make up the “default mode” network would be reliably more active during social evaluation situations. In contrast, networks underlying the visuospatial attention and action planning involved in responding to a physical threat would be reliably more active during physical danger situations. The results supported these hypotheses. In line with emerging psychological construction approaches, the findings suggest that coordinated brain networks offer a systematic way to interpret the distributed patterns that underlie the diverse situational contexts characterizing emotional life.

  1. Initial blood storage experiment

    Surgenor, Douglas MACN.

    1988-01-01

    The design of the Initial Blood Storage Experiment (IBSE) was based upon a carefully controlled comparison between identical sets of human blood cell suspensions - red cells, white cell, and platelets - one set of which was transported aboard the Columbia on a 6 day 11 hour mission, and the other held on the ground. Both sets were carried inside stainless steel dewars within specially fabricated flight hardware. Individual bags of cell suspensions were randomly assigned with respect to ground vs orbit status, dewar chamber, and specific location within the dewar. To foster optimal preservation, each cell type was held under specific optimal conditions of pH, ionic strength, solute concentration, gas tension, and temperature. An added variable in this initial experiment was provided by the use of three different polymer/plasticizer formulations for the sealed bags which held the blood cells. At termination of the experiment, aliquots of the suspensions, identified only by code, were distributed to be assayed. Assays were selected to constitute a broad survey of cellular properties and thereby maximize the chances of detection of gravitational effects. A total of 74 different outcome measurements were reported for statistical analysis. When the measurements were completed, the results were entered into the IBSE data base, at which time the data were matched with the original blood bag numbers to determine their status with respect to polymer/plasticizer type, orbit status (orbit or ground), and storage position within the experimental hardware. The data were studied by analysis of variance. Initially, type of bag and orbital status were main factors; later more detailed analyses were made on specific issues such as position in the hardware and specific plastic. If the analysis of variance indicated a statistical significance at the 5 percent level the corresponding p-value was reported.

  2. Ontario Hydro decontamination experience

    International Nuclear Information System (INIS)

    Ontario Hydro currently operates 18 nuclear electric generating units of the CANDU design with a net capacity of 12,402 MW(e). An additional 1,762 MW(e) is under construction. The operation of these facilities has underlined the need to have decontamination capability both to reduce radiation fields, as well as to control and reduce contamination during component maintenance. This paper presents Ontario Hydro decontamination experience in two key areas - full heat transport decontamination to reduce system radiation fields, and component decontamination to reduce loose contamination particularly as practised in maintenance and decontamination centres.

    International Nuclear Information System (INIS)

    The LHCb experiment is dedicated to performing a detailed study of CP symmetry violation and rare decays of B and D mesons at the Large Hadron Collider (LHC) at CERN. In order to achieve these physics goals the LHCb spectrometer must provide excellent vertexing and tracking performance both off-line and on-line. The LHCb VELO (VErtex LOcator) is the silicon micro-strip detector which surrounds the collision point and hence is critical to these aims. During routine operation the VELO detector will be located 7 mm from the LHC beam. (author)

    Ureteroscopy is an Endo-urological procedure which has been practiced around the world in all teaching centers of Urology. It presents obvious advantages. Our experience has been satisfactory, not only due to the coordinated and joint work, but for the results obtained in behalf of our patients who went back to their regular activities shortly after. As all the new procedures, it has a learning curve which is given after the initial training has been acquired but its performance will give expertise, same as radiologic technology and the development of new instruments with smaller diameter and accessories which allow the easier access to ureter and lithotripsy.

  15. Non-tokamak experiments

    International Nuclear Information System (INIS)

    The purpose of this report is to summarize the non-tokamak experiments. The non-tokamaks naturally seek to establish reactor relevance. This applies specifically to RFPs and helical systems. With LHD, a large heliotron introduced to the international fusion community at this conference, a large step toward a stellarator power plant has been taken. Another potential of non-tokamaks is that they can contribute in a unique form to the understanding of magnetic confinement and specifically to toroidal confinement because they are not tokamaks. Most of the non-tokamaks are toroidal: helical systems, RFPs, FRCs, CTs, dipoles and spheromaks. Mirrors, traps,foci are non-toroidal systems

    An engineering design and operating experience of a large, isothermal, lithium-coolant test loop are presented. This liquid metal coolant loop is called the Experimental Lithium System (ELS) and has operated safely and reliably for over 6500 hours through September 1981. The loop is used for full-scale testing of components for the Fusion Materials Irradiation Test (FMIT) Facility. Main system parameters include coolant temperatures to 4300C and flow to 0.038 m3/s (600 gal/min). Performance of the main pump, vacuum system, and control system is discussed. Unique test capabilities of the ELS are also discussed

  17. Magnetic monopole search experiments

    International Nuclear Information System (INIS)

    Experimental searches for the elusive magnetic monopole have extended over 50 years -- ever since Dirac showed that the existence of isolated magnetic charges could account for the observation of quantized electric charge. Early searches for Dirac's monopole were hampered since there was no indication of the expected monopole mass, velocity, or origin in the theory. Consequently, numerous experiments searched more or less blindly for relativistic low mass monopoles in the cosmic rays and in particle collisions at high energy accelerators. In this paper, the author reviews briefly the monopole properties which are relevant for their detection and summarize current experimental efforts using induction, ionization/excitation, and catalysis techniques

In these methods, the parameters of the studied object as well as the adequacy of the model are determined. The used method consists of a measurement and an interpretation model. The quality of the interpretation and the reliability of the model are discussed. An example of the computer modelling of an experiment using a fuzzy model is presented

Updated results from the Homestake, Kamiokande, GALLEX and SAGE detectors all show a deficit when compared to recent standard solar model calculations. Two of these detectors, GALLEX and SAGE, have recently been checked with artificial {sup 51}Cr neutrino sources. It is shown that astrophysical scenarios to solve the solar neutrino problems are not favoured by the data. There is hope that the results of forthcoming solar neutrino experiments can provide the answers to the open questions. (author) 6 figs., 3 tabs., 36 refs.

    The Apollo 15 soil-mechanics experiment has offered greater opportunity for study of the mechanical properties of the lunar soil than previous missions, not only because of the extended lunar-surface stay time and enhanced mobility provided by the lunar roving vehicle (rover), but also because four new data sources were available for the first time. These sources were: (1) the self-recording penetrometer (SRP), (2) new, larger diameter, thin-walled core tubes, (3) the rover, and (4) the Apollo lunar-surface drill (ALSD). These data sources have provided the best bases for quantitative analyses thus far available in the Apollo Program.

  3. Experiments on Superheavy Elements

    Science.gov (United States)

    Hofmann, Sigurd

    An overview of present experimental investigation of superheavy elements is given. Using cold fusion reactions which are based on lead and bismuth targets, relatively neutron deficient isotopes of the elements from 107 to 113 were synthesized at GSI in Darmstadt, Germany, and/or at RIKEN in Wako, Japan. In hot fusion reactions of 48Ca projectiles with actinide targets more neutron rich isotopes of the elements from 112 to 116 and even 118 were produced at FLNR in Dubna, Russia. Recently, part of these data which represent the first identification of nuclei located on the predicted island of SHEs were confirmed in two independent experiments. The data are compared with theoretical descriptions.

    LHC experiments are depending on the distributed EGEE infrastructure for their core activities. The Experiment Dashboard is a monitoring framework aiming to provide for the LHC experiments the overview of their activities on the EGEE infrastructure with a special emphasis in support for the user community. Existing monitoring tools are usually focusing on a specific usage like specific Grid middleware/infrastructures, specific submission tool, etc. The Experiment Dashboard has been built to aggregate existing monitoring infrastructures (from experiment specific software, infrastructure itself, monitoring tools) and provide unified views and information correlation. Experiment Dashboard is covering different areas of the LHC activities - job processing, data transfer, and data publishing. It is deployed for four LHC experiments (CMS, ATLAS, LHCb, ALICE). Some of the core functionality of the Experiment Dashboard like job monitoring can be used for other virtual organizations. Experiment Dashboard is currently ...

  5. Female physicist doctoral experiences

    2013-06-01

    The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

  6. Experiments on Washboard Road

    2007-03-01

    Granular surfaces to develop lateral ripples (so-called ``washboard" or ``corrugated" road) under the action of rolling wheels. Similar ripples are observed on railroad tracks and many other rolling, load bearing surfaces. Our aim was to investigate this instability of the flat road surface from the point of view of driven, dissipative granular dynamics. We report the results of both laboratory experiments and soft-particle direct numerical simulations. The experiment consisted of a rotating table 60 cm in radius with a thick layer of sand forming a roadbed around the circumference. A 6 cm radius hard rubber wheel, with a support stationary in the lab frame, rolled on the sand layer. We varied the speed of the table, the details of the grains and the suspension of the wheel. The ripple pattern appears as small patches of travelling waves which eventually spread to the entire circumference. The ripples drift slowly in the driving direction. Interesting secondary dynamics of the saturated ripples were observed, as well as various ripple creation and destruction events. The wavelength of the ripples can be quantized by the finite circumference of the road. All of these effects are captured qualitatively by 2D soft particle simulations in which a disk rolls over a 2D bed of polydisperse particles in a periodic box.

  7. Thermal ratcheting: Experiments

    International Nuclear Information System (INIS)

    The paper discusses experiments on the behaviour of a stainless steel under primary and secondary cyclic loads. This type of stresses, likely to induce progressive deformations, mainly affect the structural elements of a breeder reactor. The experimental set-up used for the tests allowed thin tubes to be tested under tensile stress, primary load and axial temperature gradient, and secondary cyclic load. The stresses applied have been chosen so as to show the ultimate behaviour of the material (adaptation-shakedown). The experiments have been carried out using cylindrical test specimens of steel ICL 167 SPH with a diameter of 400 mm, a thickness of 2 mm and a length of 1 m. The axial thermal gradient (3000C/cm max.) has been obtained by circulation of combustion gases of a burner and water spraying at the same level. The behaviour of the material under various thermal and mechanical loads is determined by measuring the displacements and deformations at various points. (orig.)

  8. Long Baseline Neutrino Experiment

    International Nuclear Information System (INIS)

    The selection of Homestake Mine in Lead South Dakota by the United States' National Science Foundation (NSF) as the site for Deep Underground Science and Engineering Laboratory (DUSEL) has opened new research opportunities for neutrino physics community. The proposed Long Baseline Neutrino Experiment (LBNE) will explore the interactions and transformations of a high-intensity neutrino beam by sending it from Fermi National Accelerator Laboratory (FNAL) more than 1000 kilometers through the earth to DUSEL. DUSEL would be one of the world's deepest underground laboratory and shield the LBNE neutrino detectors from cosmic particles at a depth of 4300 meters-water-equivalent (m.w.e.). Two detector technologies are considered: a 300 to 500 kTon water Cherenkov detector deployed deep underground at a DUSEL site and a 50-100 kT Liquid Argon Time-Projection Chamber (TPC). The physics sensitivities of the proposed experiments are summarized. We find that conventional horn focused wide-band neutrino beam options from FNAL aimed at a massive detector with a baseline greater than 1000 km have the best sensitivity to CP violation and the neutrino mass hierarchy for values of the mixing angle ?13 down to 2o.

  9. The VIP Experiment

    International Nuclear Information System (INIS)

    The Pauli Exclusion Principle (PEP) is a basic principle of Quantum Mechanics, and its validity has never been seriously challenged. However, given its importance, it is very important to check it as thoroughly as possible. The recently approved VIP (VIolation of Pep) experiment, represents an improved version of the Ramberg and Snow experiment (Ramberg and Snow, Phys. Lett. B238 (1990) 438). VIP shall be performed at the Gran Sasso underground laboratories, and aims to test the Pauli Exclusion Principle for electrons with unprecedented accuracy. VIP is a Collaboration among four Institutions out of three countries (LNF-INFN, and INFN Trieste Italy; SMI-Vienna, Austria; IFIN-HH, Bucharest, Romania). It uses an apparatus with CCDs (Charge Coupled Device) as detectors of X rays - looking for PEP violating transitions in Copper: transitions from the 2p level to 1s with the 1s already occupied by 2 electrons. The characteristic of such transition is the energy - displaced with respect to the normal 2p ? 1s one by about 300 eV. VIP will bring the limit on the probability that PEP is violated by electrons to 10-30, exploring so a region where new theories allow for a possible PEP violation. (authors)

  10. The EBEX Experiment

    International Nuclear Information System (INIS)

    EBEX is a balloon-borne polarimeter designed to measure the intensity and polarization of the cosmic microwave background radiation. The measurements would probe the inflationary epoch that took place shortly after the big bang and would significantly improve constraints on the values of several cosmological parameters. EBEX is unique in its broad frequency coverage and in its ability to provide critical information about the level of polarized Galactic foregrounds which will be necessary for all future CMB polarization experiments. EBEX consists of a 1.5 m Dragone-type telescope that provides a resolution of less than 8 arcminutes over four focal planes each of 4. diffraction limited field of view at frequencies up to 450 GHz. The experiment is designed to accommodate 330 transition edge bolometric detectors per focal plane, for a total of up to 1320 detectors. EBEX will operate with frequency bands centered at 150, 250, 350, and 450 GHz. Polarimetry is achieved with a rotating achromatic half-wave plate. EBEX is currently in the design and construction phase, and first light is scheduled for 2008

  11. PAC Experiments at ISOLDE

    CERN Multimedia

    2002-01-01

    The study of hyperfine interactions offers the possibility to use radioactive nuclei as probes in matter. The @g-@g perturbated angular correlation (PAC) technique following implantation has found widespread application in this field. At ISOLDE we have been investigating electric field gradients at impurities in non-cubic metals in an ongoing series of experiments. \\\\ \\\\ The small number of probe atoms necessary for these measurements make them also ideally suited for studies of surface problems like diffusion, structure and dynamics. Cd on a molybdenum O110? surface will be studied as first system. For this purpose 10|1|0~atoms of |1|1|1|mCd will be evaporated onto the clean surface and the electric field gradient for isolated adatoms on terrace sites will be determined by PAC. The UHV system constructed for such experiments at ISOLDE is shown in the schematic drawing. It is coupled to the beam line through differential pumping stations and contains standard surface treatment and analysis equipment.

  12. Blowdown experiments and interpretation

    International Nuclear Information System (INIS)

    The CANON experiments which are being carried out in Grenoble, are intended for providing data for the development of a new theoretical analysis programmed in a computer code named BERTHA, which will predict the hydrodynamic phenomena of a blowdown accident, in a light water reactor. CANON experiments, carried out under adiabatic conditions, are a means of checking methods of pressure and temperature measurements. Presently, they allow the development of a new technique of measuring the mean void fraction in a section of the channel from epithermal neutron absorption, such measurements being made every one or two milliseconds. the BERTHA code is a one-dimensional model with the hypothesis of equal velocity of each phase, but taking into account a thermodynamic nonequilibrium. The energy flux at the phase interface is evaluated with a conduction model in the liquid layer at this interface. The numerical method used is a characteristic one. It is very slow as soon as the flow is in liquid phase, but it leads to an acceptable time-step in two-phase flow. Consequently, the method is well adapted to the problem of blowdown in which the fluid remains in liquid phase during a few milliseconds

  13. Swedish nuclear energy experience

    International Nuclear Information System (INIS)

    At the Symposium on Swedish Nuclear Energy Experience at The Hague (Netherlands) 6 lectures were held providing some basic information of what Sweden has done and is doing within the nuclear field. First, ASEA-ATOM is introduced, an independent supplier of nuclear reactor systems. It has so far supplied 9 nuclear power plants aggregating 6100 MW totally. Two more, each of 1060 MW will start power generation in 1985. These plants are all based on the Boiling Water Reactor design. The first lecture presents a historical review of electricity supply and nuclear energy in Sweden. The development in favour of MWR and BWR instead of LWR and PWR is described. The ASEA-ATOM BWR design is described in detail (control systems, fuel and core design etc.). The next lecture highlights the operating experience of BWR type reactors in Sweden with respect to energy availability and capacity, scram frequencies and radiation exposure. The book further includes lectures on the implementation of large nuclear power stations, on regulatory requirements in Sweden, on Swedish radioactive waste management. At the end of the book some brochure material has been added. (G.J.P.)

    The MAJORANA Collaboration is assembling an array of HPGe detectors to search for neutrinoless double-beta decay in {sup 76}Ge. Initially, MAJORANA aims to construct a prototype module to demonstrate the potential of a future 1-tonne experiment. The design and potential reach of this prototype DEMONSTRATOR module are presented. Our proposed method uses the well-established technique of searching for neutrinoless double-beta decay in high purity Ge-diode radiation detectors that play both roles of source and detector. The use of P-PC Ge detectors present advances in background rejection and a Significantly lower energy threshold than conventional Ge detector technologies. The lower energy threshold opens up a broader and exciting physics program including searches for dark matter and axions concurrent with the double-beta decay search. The DEMONSTRATOR should establish that the backgrounds are low enough to justify scaling to tonne-scale experiment, probe the neutrino effective mass region above 100 meV, and search the low energy region with a sensitivity to dark matter. The DEMONSTRATOR will be sited at the 4850-ft level (4200 m.w.e) of the Sanford Underground Laboratory at Homestake and preparations for construction are currently underway.

    The ELBE center for high power radiation sources is the largest user facility in the Helmholtz-Zentrum Dresden- Rossendorf. The facility is based on a 36 MeV superconducting RF Linac which can be operated up to 1.6 mA in cw mode. The electron beam is used to generate secondary radiation, such as infrared light (Free Electron Lasers), coherent THz radiation, MeV-Bremsstrahlung, fast neutrons and positrons for a wide range of basic research like semiconductor physics, nuclear astrophysics and radio biological investigations. Two high power laser systems (500 TW Ti:Sa laser, 2 PW diode pumped laser) are under construction for laser acceleration experiments and X-ray generation by Thomson scattering. The FELs are in operation since 2004 (mid-IR FEL, 4-22?m) and 2006 (far-IF FEL, 20-250?m). The fundamental features of the ELBE IR FELs, the FEL instrumentation and advanced beam diagnostics for the photon beam are described. During ten years of user operation experiences and statistical data were collected.

  17. Current containment blowdown experiments

    International Nuclear Information System (INIS)

    The containment experiments with the HDR are made in order to measure transient load processes in simulated loss-of-coolant accidents in a typical full-pressure containment, and to use these measured data for verifying and improving existing computer programmes. First experiments of this kind have been started as integral tests on a containment mockup on a scale of 1:4 and 1:64, respectively, at the Battelle Institute for the purpose of confirming the conservativity of the computer programmes for the determination of the thermodynamic loads in the containment, and also in the case of loss-of-coolant accidents such as PREGA, ZOCO, CONDRU, COFLOW, DDIFF and COCO. Evaluating the experimental data and trying to apply these conservative results to real plants, one had to realize that the variety of parameters not sufficiently defined is too large to be determined by integral tests. The effects of the discharge coefficients of the flow conditions, of the heat transfer coefficients, the water entrainment, etc. have been stronger than expected in some cases and had to be eliminated from the evaluation in order to obtain transferrable experimental results.

    1993-01-01

    The Halogen Occultation Experiment (HALOE) uses solar occultation to measure vertical profiles of O3, HCl, HF, CH4, H2O, NO, NO2, aerosol extinction, and temperature versus pressure with an instantaneous vertical field of view of 1.6 km at the earth limb. Latitudinal coverage is from 80 deg S to 80 deg N over the course of 1 year and includes extensive observations of the Antarctic region during spring. The altitude range of the measurements extends from about 15 km to about 60-130 km, depending on channel. Experiment operations have been essentially flawless, and all performance criteria either meet or exceed specifications. Internal data consistency checks, comparisons with correlative measurements, and qualitative comparisons with 1985 atmospheric trace molecule spectroscopy (ATMOS) results are in good agreement. Examples of pressure versus latitude cross sections and a global orthographic projection for the September 21 to October 15, 1992, period show the utility of CH4, HF, and H2O as tracers, the occurrence of dehydration in the Antarctic lower stratosphere, the presence of the water vapor hygropause in the tropics, evidence of Antarctic air in the tropics, the influence of Hadley tropical upwelling, and the first global distribution of HCl, HF, and NO throughout the stratosphere. Nitric oxide measurements extend through the lower thermosphere.

    Liquid fuel combustion provides a major portion of the world's energy supply. In most practical combustion devices, liquid burns after being separated into a droplet spray. Essential to the design of efficient combustion systems is a knowledge of droplet combustion behavior. The microgravity environment aboard spacecraft provides an opportunity to investigate the complex interactions between the physical and chemical combustion processes involved in droplet combustion without the complications of natural buoyancy. Launched on STS-83 and STS-94 (April 4 and July 1, 1997), the Droplet Combustion Experiment (DCE) investigated the fundamentals of droplet combustion under a range of pressures (0.25 to 1 atm), oxygen mole fractions (burn single, freely deployed droplets in microgravity. Diagnostics systems included a 35-mm high-speed motion picture camera (see the following sequence of photos) with a backlight to photograph burning droplets and a camcorder to monitor experiment operations. Additional diagnostics included an ultraviolet-light-sensitive CCD (charge couple discharge) camera to obtain flame radiation from hydroxyl radicals (see the final figure) and a 35-mm SLR (single-lens-reflex) camera to obtain color still photographs of the flames.

    Petascale High-Performance Computing (HPC) systems are among the largest systems in the world. Intrepid, one such system, is a 40,000 node, 556 teraflop Blue Gene/P system that has been deployed at Argonne National Laboratory. In this paper, we provide some background about the system and our administration experiences. In particular, due to the scale of the system, we have faced a variety of issues, some surprising to us, that are not common in the commodity world. We discuss our expectations, these issues, and approaches we have used to address them. HPC systems are a bellwether for computing systems at large, in multiple regards. HPC users are motivated by the need for absolute performance; this results in two important pushes. HPC users are frequently early adopters of new technologies and techniques. Successful technologies, like Infiniband, prove their value in HPC before gaining wider adoption. Unfortunately, this early adoption alone is not sufficient to achieve the levels of performance required by HPC users; parallelism must also be harnessed. Over the last 15 years, beowulf clustering has provided amazing accessibility to non-HPC-savvy and even non-technical audiences. During this time, substantial adoption of clustering has occurred in many market segments unrelated to computational science. A simple trend has emerged: the scale and performance of high-end HPC systems are uncommon at first, but become commonplace over the course of 3-5 years. For example, in early 2003, several systems on the Top500 list consisted of either 1024 nodes or 4096-8192 cores. In 2008, such systems are commonplace. The most recent generation of high-end HPC systems, so called petascale systems, are the culmination of years of research and development in research and academia. Three such systems have been deployed thus far. In addition to the 556 TF Intrepid system at Argonne National Laboratory, a 596 TF Blue Gene/L-based system has been deployed at Lawrence Livermore National Laboratory, and a 504 TF Opteron-based system has been deployed at Texas Advanced Computing Center (TACC). Intrepid is comprised of 40,960 nodes with a total of 163,840 cores. While systems like these are uncommon now, we expect them to become more widespread in the coming years. The scale of these large systems impose several requirements upon system architecture. The need for scalability is obvious, however, power efficiency and density constraints have become increasingly important in recent years. At the same time, because the size of administrative staff cannot grow linearly with the system size, more efficient system management techniques are needed. In this paper we will describe our experiences administering Intrepid. Over the last year, we have experienced a number of interesting challenges in this endeavor. Our initial expectation was for scalability to be the dominant system issue. This expectation was not accurate. Several issues expected to have minor impact have played a much greater role in system operations. Debugging, due to the large numbers of components used in scalable system operations, has become a much more difficult endeavor. The system has a sophisticated monitoring system, however, the analysis of this data has been problematic. These issues are not specific to HPC workloads in any way, so we expect them to be of general interest. This paper consists of three major parts. First, we will provide a detailed overview of several important aspects of Intrepid's hardware and software. In this, we will highlight aspects that have featured prominently in our system management experiences. Next, we will describe our administration experiences in detail. Finally, we will draw some conclusions based on these experiences. In particular, we will discuss the implications for the non-HPC world, system managers, and system software developers.

  2. The Virtual Arizona Experience

    2012-12-01

    To commemorate the once-in-a-lifetime event of Arizona's hundredth birthday, the Centennial Commission and the Governor of Arizona envisioned a museum and companion website that would capture the state's history, celebrate its people, and embrace its future. Working with world-renowned museum designers, the state began to seek ideas from across Arizona to create plans for a journey of discovery through science and the humanities. The museum would introduce visitors to some of the people who nurtured the state through its early years and others who are innovating its tomorrows. Showcases would include the resources and experiences that shaped the state's history and are transforming its present day, highlighting the ingenuity that tamed the wild frontier and is envisioning Arizona's next frontiers through science and technology. The Arizona Experience (www.arizonaexperience.org) was initially intended to serve as the web presence for the physical museum, but as delays occurred with the physical museum, the site has quickly developed an identify of its own as an interactive, multimedia experience, reaching a wider audience with functions that would be difficult or expensive to produce in a museum. As leaders in scientific and technological innovation in the state, the Arizona Geological Survey was tasked with designing and creating the Arizona Experience site. The general themes remain the same; however, the site has added content and applications that are better suited to the online environment in order to create a rich, dynamic supplement to a physical museum experience. The website offers the features and displays of the future museum with the interactive nature and learning environment of the web. This provides an encyclopedic overview of the State of Arizona by subject matter experts in a manner that is free and open to the public and erases socio-economic, political, and physical boundaries. Over the Centennial Year of 2012 the site will release a new theme and explore the people, land, and innovations that shape the themes. Themes include (in order of release) Celebrates, Mining & Minerals, Biotech & Life Sciences, Sports & Recreation, Energy, Water, Technology & Aerospace, People & Culture, Ranching & Agriculture, Native American Culture, Astronomy, 21st Century Workforce, and a Best of 2012 release. The materials developed for the site come from content matter experts across the state including academic institutions, historical societies, museums, and professional associations. Currently there are over 300 content providers contributing resources, data, and videos to the site. AZGS interactions with science and technology organizations, associations, and businesses have been critical as we work to engage visitors and industry with the opportunities in Arizona, and translate innovative research and scientific application for a more generalized audience. In addition, we are involving K-12 educators in using the site content and cutting edge technology for developing classroom STEM related content linked to curriculum subject areas.

  3. Aesthetic experience of dance performances

    2012-01-01

    Full Text Available In this study the aesthetic experience of dance performances is investigated. The study includes construction of an instrument for measuring the aesthetic experience of dance performances and an investigation of the structure of both dancers’ and spectators’ aesthetic experience. The experiments are carried out during eight different performances of various dance forms, including classical ballet, contemporary dance, flamenco and folklore. Three factors of aesthetic experience of dance performances are identified: Dynamism, Exceptionality and Affective Evaluation. The results show that dancers’ aesthetic experience has a somewhat different factorial structure from that of the spectators’. Unlike spectators’ aesthetic experience, dancers’ aesthetic experience singles out the Excitement factor. The results are discussed within the context of dancers’ proprioception and spectators’ exteroception since these findings confirm the idea of a significant role of proprioception in dancers’ aesthetic experience.

    One of the purposes of the SQA effort at LLNL is to attempt to determine the 'goodness' of the research codes used for various scientific applications. Typically these are two and three dimensional multi-physics simulation and modeling codes. These legacy research codes are used for applciations such as atmospheric dispersion modeling and analysis and prediction of the performance of engineered systems. These codes are continually subjected to automated regression test suites consisting of verified and validated expected results. Code is managed in repositories. Experience level of developers is high in the knowledge domain, platforms, and languages used. Code size of the multi-physics code used in this study was 578,242 lines excluding comment and blank lines or 5538.7 function points. Languages were 70% C++, 20% C, and 10% Fortran. The code has 130 users and a development team of 14 and an embedded SQE. The code has achieved 100% prime feature test coverage, 73.6% functional test coverage, and 71.5% statement test coverage. The average cyclomatic complexity of the code was 6.25. The codes have evolved over 10 years. Research codes are challenging because there is a desire to balance agility with discipline as well as compliance with DOE standards. Agility is important to allow experimentation with new algorithms and addition of the latest physics features. Discipline is important to increase the quality of the codes. Automation of processes and defect prevention/detection are deployed throughout the software development process. Since resarch codes are a small segment of the software industry, not much information exists in terms of reliability studies on these types of codes. This paper describes attempts to determine the goodness of these research codes. Goodness defined as both correctness of the codes and their fault densities. Correctness is determined by user interviews, peer review; feature based automated testing, and coverage measurement. This paper focuses on the fault density aspect of goodness and reliability of the codes in particular. The approach taken was to use multiple fault density prediction methods and compare results to actual experimentation and other industry studies on fault density. As a result of the predictions and experiments our confidence in the prediction methods was increased and our confidence in the goodness of the code from a fault density perspective was given more context. A large unintended benefit of these experiments was to find defects hidden for years in the codes when using the Monte Carlo reliability testing results to develop heuristic based bug driven tests.

    This document describes the PANTHER R&D Application, a proof-of-concept user interface application developed under the PANTHER Grand Challenge LDRD. The purpose of the application is to explore interaction models for graph analytics, drive algorithmic improvements from an end-user point of view, and support demonstration of PANTHER technologies to potential customers. The R&D Application implements a graph-centric interaction model that exposes analysts to the algorithms contained within the GeoGraphy graph analytics library. Users define geospatial-temporal semantic graph queries by constructing search templates based on nodes, edges, and the constraints among them. Users then analyze the results of the queries using both geo-spatial and temporal visualizations. Development of this application has made user experience an explicit driver for project and algorithmic level decisions that will affect how analysts one day make use of PANTHER technologies.

    International Nuclear Information System (INIS)

    Titanium is a reference material for the construction of waste containers in the Canadian Nuclear Fuel Waste Management Program. It has been in industrial service for over 30 a, often in severe corrosion environments, but it is still considered a relatively exotic material with limited operating history. This has arisen because of the aerospace applications of this material and the misconception that the high strength-to-weight ratio dominates the choice of this material. In fact, the advantage of titanium lies in its high reliability and excellent corrosion resistance. It has a proven record in seawater heat exchanger service and a demonstrated excellent reliability even in polluted water. For many reasons it is the technically correct choice of material for marine applications. In this report we review the industrial service history of titanium, particularly in hot saline environments, and demonstrate that it is a viable waste container material, based upon this industrial service history and operating experience.

  7. INITIAL COOLING EXPERIMENT (ICE)

    CERN Multimedia

    1979-01-01

    ICE was built in 1977, using the modified bending magnets of the g-2 muon storage ring (see 7405430). Its purpose was to verify the validity of stochastic and electron cooling for the antiproton project. Stochastic cooling proved a resounding success early in 1978 and the antiproton project could go ahead, now entirely based on stochastic cooling. Electron cooling was experimented with in 1979. The 26 kV equipment is housed in the cage to the left of the picture, adjacent to the "e-cooler" located in a straight section of the ring. With some modifications, the cooler was later transplanted into LEAR (Low Energy Antiproton Ring) and then, with further modifications, into the AD (Antiproton Decelerator), where it cools antiprotons to this day (2006).

    Searching the space of policies directly for the optimal policy has been one popular method for solving partially observable reinforcement learning problems. Typically, with each change of the target policy, its value is estimated from the results of following that very policy. This requires a large number of interactions with the environment as different polices are considered. We present a family of algorithms based on likelihood ratio estimation that use data gathered when executing one policy (or collection of policies) to estimate the value of a different policy. The algorithms combine estimation and optimization stages. The former utilizes experience to build a non-parametric representation of an optimized function. The latter performs optimization on this estimate. We show positive empirical results and provide the sample complexity bound.

    The determination of the neutrino mass is an open issue in modern particle physics and astrophysics. The direct mass measurement is the only theory-unrelated experimental tool capable to probe such quantity. The HOLMES experiment will measure the end-point energy of the electron capture decay of ^{163} Ho, aiming at a statistical sensitivity on the neutrino mass around 1 eV/c^2 . In order to acquire the large needed statistics by keeping the pile-up contribution as low as possible, 1000 transition edge sensors will be readout simultaneously with the frequency domain readout, a multiplexing technique where the multiplex factor is only limited by the bandwidth of the available commercial fast digitizers. We outline here the HOLMES project with its technical challenges, and its status and perspectives.

    The VIP (Violation of the Pauli Exclusion Principle) experiment is dedicated to check the validity of one of the basic principles of modern physics. This investigation is done searching for anomalus X-rays emitted by copper atoms in a conductor: any detection of these anomalous X-rays would mark a Pauli forbidden transition. VIP is currently taking data at the Gran Saso underground laboratories, and its scientific goal is to improve by three-four orders of magnitude the previous limit on the probability of Pauli violating transitions, bringing it into the 10-29÷ -30 region. The new experimental results and future plans are presented. The PDF file for this article was corrected and the names and affiliations were amended on 4 September 2009.

Career Guidance in Russia, despite the vast experience of its implementation, is experiencing serious difficulties. In this regard, it is important to take into account the international experience career-oriented activities, such as in the developed countries of North America and the European Union as well as in several Asian countries with rapidly growing economies and a large demographic potential, taking into account the best variants for the Russian education system. Methods. The experience of career-oriented work undertaken with pupils of the USA, Canada, Israel, France, UK, Germany, Denmark, Sweden, Japan, Singapore, China and India is shown on the basis of the comparative analysis of different publications and information sources. The author has made an attempt to generalize the principles of psycho-pedagogical and administrative assistance in professional self-determination of senior pupils abroad. Scientific novelty. The approaches to career-oriented activities in countries with different levels of economic development are compared for the first time. Some principles are revealed. Firstly, the higher the income level per capita in the country, the greater attention is given to vocational guidance. The politics in the developed countries is based on interests of the individual: children’s acquaintance with the world of professions begins already at younger school and the moment of definitive selfdetermination is postponed till the end of their senior stage of education; the possibility of direction change of professional preparation in case of detection of discrepancy of qualities of the pupil to originally selected profile is provided. Career-oriented activity in developing countries, on the contrary, is rigidly coordinated to requirements of economy and a labour market; earlier fixing of professional preferences and less flexible relation to an unsuccessful choice of a speciality or profession of the youth is marked there. The most typical characteristics of foreign career-oriented schemes are the following: the organisation of continuous training lasting throughout all school; supervision over students’ achievements, propensities and hobbies; portfolio or cumulative files drafting and recording data of all pupil’s results while professional consulting and selection of entrants for vocational training continuation in colleges or high schools. The author points out the general characteristic: the economy requirement for high quality experts on the basis of selection of the pupils who are able to master high-end technologies and have an obvious potential of professional growth and personal development. Practical significance. The research materials and implementations can be useful to Russian career-and professional specialists, and the experts who are engaged in education management.

    2007-12-01

    Although there is widespread interest in the use of clickers in astronomy classrooms, there remains controversy over their effectiveness and confusion as to how and when to use them. At UMass Amherst, where nearly 1000 students take large-lecture introductory astronomy courses each term, we have studied how to combine "new" and "old" learning methods to create course "components" (e.g., Stage & Schneider, BAAS 38, 1145). One of the most exciting branches of this study is the combination of clicker questions with physical and multi-media demonstrations. This provides opportunities for students to actually participate in demonstrations, rather than just observe them. This transforms the student experience from passive audience member to active experimenter. In this session, we discuss how to formulate pre- and post- demo questions and how different question styles may be employed. We also present our approach to assessment and discuss the results from our classrooms.

    Flammable gases are often used in detectors for physics experiments. The storage, distribution and manipulation of such flammable gases present several safety hazards. As most flammable gases cannot be detected by human senses, specific well-placed gas detection systems must be installed. Following a request from the user group and in collaboration with CERN safety officers, risk analyses are performed. An external contractor, who needs to receive detailed user requirements from CERN, performs the installations. The contract is passed on a guaranteed results basis. Co-ordination between all the CERN groups and verification of the technical installation is done by ST/AA/AS. This paper describes and focuses on the structured methodology applied to implement such installations based on goal directed project management techniques (GDPM). This useful supervision tool suited to small to medium sized projects facilitates the task of co-ordinating numerous activities to achieve a completely functional system.

    The Cibola Flight Experiment (CFE) is an experimental small satellite carrying a reconfigurable processing instrument developed at the Los Alamos National Laboratory that demonstrates the feasibility of using FPGA-based high-performance computing for sensor processing in the space environment. The CFE satellite was launched on March 8, 2007 in low-earth orbit and has operated extremely well since its deployment. The nine Xilinx Virtex FPGAs used in the payload have been used for several high-throughput sensor processing applications and for single-event upset (SEU) monitoring and mitigation. This paper will describe the CFE system and summarize its operational results. In addition, this paper will describe the results from several SEU detection circuits that were performed on the spacecraft.

  20. A European experiment

    International Nuclear Information System (INIS)

    The Joint European Torus (JET) is an experiment in nuclear fusion research which was planned as a joint effort between national research laboratories and Euratom. Before approval was given for it to be built it became a political football in the European Communities. This book describes the background against which JET was conceived, designed and planned. It gives a chronological account of the political imbroglio which followed between 1975 and 1978 and indicates how close the project came to collapse at one point. In addition to the two years' delay caused by Ministerial conflicts over its siting, the project suffered many compromises in its financing, its staffing and its organisation. An account is given of the unique structure of the European Communities and its procedures, which shows how idealism constantly faces reality. The role of Euratom is discussed, taking into account the difference between its approach to applications of nuclear fission as opposed to those of nuclear fusion. (author)

    Reports on the experimental progress observed during the last year at high energy accelerators. This energy range can be separated into two regions: (i) high energy, well above the resonance region, ranging from approximately 10 to 79 GeV, experimenting with a variety of particles like pi /sup +or-/, K/sup +or-/, p, p, n, K degrees and most recently with hyperons; (ii) very high energy, up to 2000 GeV, until last year reserved to cosmic rays, now accessible with proton storage rings. This region is restricted to the study of pp collisions and it is limited by rates to the investigation of cross sections >or approximately=10/sup -34/ cm/sup 2/. Some elementary but representative processes which have been studied in the full energy region are covered. These are: particle production (inclusive reactions); elastic scattering; and total cross section. (23 refs).

  3. Tritium neutrino mass experiments

    International Nuclear Information System (INIS)

    The current status of the experimental search for neutrino mass is reviewed, with emphasis on direct kinematic methods, such as the beta decay of tritium. The situation concerning the electron neutrino mass as measured in tritium beta decay is essentially unchanged from a year ago, although a great deal of experimental work is in progress. The ITEP group continues to find evidence for a nonzero mass, now slightly revised to 26(5) eV. After correcting for recently discovered errors in the energy loss distribution and source thickness, however, the Z/umlt u/rich group still claims and upper limit of 18 eV. There may be evidence for neutrino mass and mixing in the SN1987a data, in the same range suggested by the ITEP experiment. 42 refs., 3 figs

  4. Experiments of reactivity inserts

    International Nuclear Information System (INIS)

    Experiments of reactivity insertion have been performed in the IPEN-MB-01 critical facility. Small Cd rods were built with control mecanisms similar to control rods, so that a wide range of reactivity could be inserted into the core. Reactivity insertions in a step fashion were obtained by dropping the Cd rods from the middle to outside of the core. The signals of two detectors monitoring the transient were analyzed through inverse kinetics after verifying that the possible spatial redistribution of the neutron flux would not invalidate such analysis. The reactivity value obtained for the perturbation via a differential control rod worth curve differed only 1.6% from the inverse kinetics estimate. (author)

    The rapid expansion of remote sensing capability over the last two decades will take another major leap forward with the advent of the Earth Observing System (Eos). An approach is presented that will permit experiments and demonstrations in onboard information extraction. The approach is a non-intrusive, eavesdropping mode in which a small amount of spacecraft real estate is allocated to an onboard computation resource. How such an approach allows the evaluation of advanced technology in the space environment, advanced techniques in information extraction for both Earth science and information science studies, direct to user data products, and real-time response to events, all without affecting other on-board instrumentation is discussed.

    OPERA is a neutrino oscillation experiment designed to perform a nu\\_tau appearance search at long distance in the future CNGS beam from CERN to Gran Sasso. It is based on the nuclear emulsion technique to distinguish among the neutrino interaction products the track of a tau produced by a nu\\_tau and its decay tracks. The OPERA detector is presently under construction in the Gran Sasso underground laboratory, 730 km from CERN, and will receive its first neutrinos in 2006. The experimental technique is reviewed and the development of the project described. Foreseen performances in measuring nu\\_tau appearance and also in searching for nu\\_e appearance are discussed.

    The SNO+ experiment is the follow-up to the Sudbury Neutrino Observatory (SNO). The heavy water that was in SNO will be replaced with a liquid scintillator of linear alkylbenzene (plus fluor). SNO+ has many physics goals including detecting pep and CNO solar neutrinos, detecting geo-neutrinos, studying reactor neutrino oscillations, serving as a supernova neutrino detector and carrying out a search for neutrinoless double beta decay by adding neodymium to the liquid scintillator. Since a large amount of 150Nd isotope can be added to SNO+, a competitive search would be possible, with sensitivity below 100 meV using natural Nd and sensitivity below 40 meV with enriched neodymium.

  10. The PODS diversity experiment

    International Nuclear Information System (INIS)

    A high integrity system typically has a number of redundant components operating in parallel to reduce the probability of a system failure. If the component failures were random, then the probability of several components failing simultaneously would be much smaller than the failure probability of any single component. However, should the components contain common design flaws, then more than one component could fail simultaneously due to a common cause (a common mode failure). This would increase the probability of a system failure. For a computer-based system where the same software component is being run in each processor, any software fault is a potential cause of common mode failure. One method of reducing common software faults is to use diverse software in each processor (n-version programming). This paper discusses how the use of software diversity raises a number of issues. A diversity experiment is described

  11. The pentomic experience

    International Nuclear Information System (INIS)

    The Pentomic experience is presented in outline form. The subject is discussed under the following topics: context, objectives, description, assessment, and lessons. The context included President Eisenhower's open-quotes new lookclose quotes strategy and service rivalry for nuclear share. The objectives for the Pentomic Division included dual capability with nuclear emphasis, strategic mobility, smaller, and major organizational changes. The Pentomic Division is described as a separate division in which the infantry battle group is a basic building block. The Pentomic Division was designed to be dual-capable in both conventional and nuclear warfare and was assessed or perceived to be neither. The possible reasons for the failure of the concept were: problem too hard, wrong solution, premature solution, weak implementation, and overambitious goals

  12. Reactor operation experience

    International Nuclear Information System (INIS)

    Since the TRIGA Users Conference in Helsinki 1970 the TRIGA reactor Vienna was in operation without any larger undesired shutdown. The integrated thermal power production by August 15 1972 accumulated to 110 MWd. The TRIGA reactor is manly used for training of students, for scientific courses and research work. Cooperation with industry increased in the last two years either in form of research or in performing training courses. Close cooperation is also maintained with the IAEA, samples are irradiated and courses on various fields are arranged. Maintenance work was performed on the heat exchanger and to replace the shim rod magnet. With the view on the future power upgrading nine fuel elements type 110 have been ordered recently. Experiments, performed currently on the reactor are presented in details

  13. Reviewing operational experience feedback

    International Nuclear Information System (INIS)

    The purpose of this document is to provide detailed supplementary guidance to OSART experts to aid in the evaluation of operational experience feedback (OEF) programmes at nuclear power plants. The document begins by describing the objectives of an OEF programme. It goes on to indicate preparatory work and investigatory guidance for the expert. Section 5 describes attributes of an excellent OEF programme. Appended to these guidelines are examples of OEF documents from various plants. These are intended to help the expert by demonstrating the actual implementation of OEF in practice. These guidelines are in no way intended to conflict with existing national regulations and rules. A comprehensive OEF programme, as described in Section 2, would be impossible to evaluated in detail in the amount of time typically allocated for assessing OEF in an OSART review. The expert must use his or her time wisely by concentrating on those areas that appear to be the weakest

  14. Neutron experiments at LAMPF

    International Nuclear Information System (INIS)

    The problem of the nucleon-nucleon force is the most fundamental in nuclear physics and is basic to particle physics. However, in the energy range from pion production threshold to 1 GeV, the N-N interaction is rather poorly determined. In general, at these energies, there is no unique set of phase shifts and coupling parameters; the I = 1 parameters are known at least quantitatively, but the I = 0 parameters are not even known qualitatively. This is illustrated by the variation of 3S1 phase shift from -17 to 350 in the three solutions of the energy-independent nucleon-nucleon phase shift analysis of Glonti. In addition, these results are in considerable disagreement with the analyses of MacGregor. This is due to the paucity of the n-p scattering data including polarization and triple scattering parameters. Furthermore, as will be shown later, there is considerable disagreement between the results from different groups in the intermediate energy region of even so basic an observable as the n-p differential cross section. Therefore, a long range program was started for the definitive determination of the n-p interaction at LAMPF energies (300 to 800 MeV). This is an ambitious project which will ultimately require the performance of many experiments. Each successive set of measurements will clarify our understainding of the n-p system to some degree and simplify the problems of the subsequent measurements. In this communication a general description of the experimental setup and the various neutron experiments performed at LAMPF is given

  15. Spent fuel storage experience

    International Nuclear Information System (INIS)

    Irradiated nuclear fuel has been stored in water pools at essentially all nuclear reactors, beginning with the earliest plants in 1943. Fuel from water-cooled power reactors is clad either with Zircaloy or with stainless steel. Zircaloy-clad fuel has been stored US pools since 1959. Some experimental stainless-steel-clad fuel was stored for 12 yr in the US before reprocessing. Canadian Zircaloy-clad fuel has been stored since 1962. There has been no evidence that the fuel has degraded during pool storage, based principally on visual observations and radiation monitoring of pool air and water. However, several fuel rods have been subjected to metallographic examination after pool exposures up to 11 yr, also with no evidence that the fuel cladding has degraded in the pool. Canadian fuel stored up to 10 yr was returned to a reactor and performed well. Favorable storage experience also has been indicated for other countries with fuel residence times of 5 to 10 yr. The pool storage environment is high-purity water at 5.3 to 7.5 pH, except for pools for pressurized water reactors, which utilize boric acid pool chemistry at 4.5 to 6.0 pH. Pool water temperatures generally range between 20 and 500C. The favorable storage experience, demonstrated technology, successful handling of fuel with reactor-induced defects, benign storage environments, and corrosion-resistant materials offer sufficient bases to proceed with expanded storage capacities and extended fuel storage until questions regarding fuel reprocessing and final storage of nuclear wastes have been resolved. Some surveillance is justified to detect degradation if it becomes significat. Surveillance programs are already under way in several countries. 1 figure, 6 tables

  16. Terawatt fiber pinch experiments

    International Nuclear Information System (INIS)

    Fiber pinches have been found to be less prone to disruptive instabilities (m = o type) than predicted by MHD theory (pinch life time > 100 MHD growth times). Comparing different experiments, this remarkable macroscopical stability seems to scale with driver power. Fiber experiments performed at the pulseline KALIF (1,6 TW, 2 MV, 2?) show no pinch disruptions during the whole current pulse (> 120 ns) if the initial fiber radius exceeds a critical limit (> 10 ?m). From optical framing pictures it is realized that local pinch column neckings develop when the ratio of the pinch current to the initial fiber radius exceeds 15 kA/?m. This leads to local radiative collapses (micropinches) near the cathode first and up to 20 ns later near the anode as seen on X-ray streak pictures. A few ns after these short-lived (? ns) micropinches a more or less axially inhomogeneous hot (Te 300 kA) intensive hard X-ray emission starts immediately after the micropinches and no hot pinch plasma develops. Depending on power input and fiber radius the fiber ablation and ionization process lasts for more than 20 ns. It has been found that reduced power input per electron-ion pair during fiber ablation and ionization reduces initial discharge expansion whereas high power input per plasma particle during pinch phase improves the hot pinch plasma (axial homogeneity and confinement). From these contradictory power requirements it is concluded that a solid fiber is not the best start condition for these Z-pinches that need initial pinch conductivity and compressibility in order to further improve axial homogeneity and confinement

    The solar arrays flight experiment consists of four experiments on two different flights. The first experiment, termed the baseline, has a basic purpose to demonstrate the flight readiness of lightweight solar array technology for solar electric propulsion and other payload power applications. The early availability of this experiment and its basic large space structure characteristics make it a logical candidate to demonstrate other disciplines critical to large space structures. These demonstrations form the basis for three other solar array experiments, two in remote sensing and one in control. All of these experiments are briefly reviewed in this paper.

    2001-01-01

    A space-based experiment is currently under development to study diffusion-controlled, gas-phase, low temperature oxidation reactions, cool flames and auto-ignition in an unstirred, static reactor. At Earth's gravity (1g), natural convection due to self-heating during the course of slow reaction dominates diffusive transport and produces spatio-temporal variations in the thermal and thus species concentration profiles via the Arrhenius temperature dependence of the reaction rates. Natural convection is important in all terrestrial cool flame and auto-ignition studies, except for select low pressure, highly dilute (small temperature excess) studies in small vessels (i.e., small Rayleigh number). On Earth, natural convection occurs when the Rayleigh number (Ra) exceeds a critical value of approximately 600. Typical values of the Ra, associated with cool flames and auto-ignitions, range from 104-105 (or larger), a regime where both natural convection and conduction heat transport are important. When natural convection occurs, it alters the temperature, hydrodynamic, and species concentration fields, thus generating a multi-dimensional field that is extremely difficult, if not impossible, to be modeled analytically. This point has been emphasized recently by Kagan and co-workers who have shown that explosion limits can shift depending on the characteristic length scale associated with the natural convection. Moreover, natural convection in unstirred reactors is never "sufficiently strong to generate a spatially uniform temperature distribution throughout the reacting gas." Thus, an unstirred, nonisothermal reaction on Earth does not reduce to that generated in a mechanically, well-stirred system. Interestingly, however, thermal ignition theories and thermokinetic models neglect natural convection and assume a heat transfer correlation of the form: q=h(S/V)(T(bar) - Tw) where q is the heat loss per unit volume, h is the heat transfer coefficient, S/V is the surface to volume ratio, and (T(bar) - Tw ) is the spatially averaged temperature excess. This Newtonian form has been validated in spatially-uniform, well-stirred reactors, provided the effective heat transfer coefficient associated with the unsteady process is properly evaluated. Unfortunately, it is not a valid assumption for spatially-nonuniform temperature distributions induced by natural convection in unstirred reactors. "This is why the analysis of such a system is so difficult." Historically, the complexities associated with natural convection were perhaps recognized as early as 1938 when thermal ignition theory was first developed. In the 1955 text "Diffusion and Heat Exchange in Chemical Kinetics", Frank-Kamenetskii recognized that "the purely conductive theory can be applied at sufficiently low pressure and small dimensions of the vessel when the influence of natural convection can be disregarded." This was reiterated by Tyler in 1966 and further emphasized by Barnard and Harwood in 1974. Specifically, they state: "It is generally assumed that heat losses are purely conductive. While this may be valid for certain low pressure slow combustion regimes, it is unlikely to be true for the cool flame and ignition regimes." While this statement is true for terrestrial experiments, the purely conductive heat transport assumption is valid at microgravity (mu-g). Specifically, buoyant complexities are suppressed at mu-g and the reaction-diffusion structure associated with low temperature oxidation reactions, cool flames and auto-ignitions can be studied. Without natural convection, the system is simpler, does not require determination of the effective heat transfer coefficient, and is a testbed for analytic and numerical models that assume pure diffusive transport. In addition, mu-g experiments will provide baseline data that will improve our understanding of the effects of natural convection on Earth.

  6. SPRUCE experiment data infrastructure

    The Carbon Dioxide Information Analysis Center (CDIAC) at Oak Ridge National Laboratory (ORNL), USA has provided scientific data management support for the US Department of Energy and international climate change science since 1982. Among the many data activities CDIAC performs are design and implementation of the data systems. One current example is the data system and network for SPRUCE experiment. The SPRUCE experiment (http://mnspruce.ornl.gov) is the primary component of the Terrestrial Ecosystem Science Scientific Focus Area of ORNL's Climate Change Program, focused on terrestrial ecosystems and the mechanisms that underlie their responses to climatic change. The experimental work is to be conducted in a bog forest in northern Minnesota, 40 km north of Grand Rapids, in the USDA Forest Service Marcell Experimental Forest (MEF). The site is located at the southern margin of the boreal peatland forest. Experimental work in the 8.1-ha S1 bog will be a climate change manipulation focusing on the combined responses to multiple levels of warming at ambient or elevated CO2 (eCO2) levels. The experiment provides a platform for testing mechanisms controlling the vulnerability of organisms, biogeochemical processes and ecosystems to climatic change (e.g., thresholds for organism decline or mortality, limitations to regeneration, biogeochemical limitations to productivity, the cycling and release of CO2 and CH4 to the atmosphere). The manipulation will evaluate the response of the existing biological communities to a range of warming levels from ambient to +9°C, provided via large, modified open-top chambers. The ambient and +9°C warming treatments will also be conducted at eCO2 (in the range of 800 to 900 ppm). Both direct and indirect effects of these experimental perturbations will be analyzed to develop and refine models needed for full Earth system analyses. SPRUCE provides wide range continuous and discrete measurements. To successfully manage SPRUCE data flow and support climate change research, CDIAC has designed flexible data collection system using proven network technologies and taking advantage of existing software components. The SPRUCE data system comprised primarily of a set of network components, relational database, a web server to monitor data collection status, FTP server and replication/backup arrangement. Later the data interface on the existing website will be expanded to allow users to query the SPRUCE collection in a variety of ways and then subset, visualize and download the data. From the perspective of data stewardship, on the other hand, this system is designed for CDIAC to easily control database content, automate data movement, track data provenance, manage metadata content, and handle additions and corrections. In this presentation, we share our approaches to meet the challenges of designing and constructing data system for managing sources of high volume in situ observations in a remote location. It will demonstrate the dataflow starting from the sensors and ending at the archiving/distribution points, discuss types of hardware and software used, and examine considerations that were used to choose them.

    2003-01-01

    Degeneracies of the neutrino oscillation parameters are explained using the $\\sin^22\\theta_{13}$--$s^2_{23}$ plane. Measurements of $\\sin^22\\theta_{13}$ by reactor experiments are free from the parameter degeneracies which occur in accelerator appearance experiments, and reactor experiments play a role complementary to accelerator experiments. It is shown that the reactor measurement may be able to resolve the degeneracy in $\\theta_{23}$ if $\\sin^22\\theta_{13}$ and $\\cos^22\\theta_{23}$ are relatively large.

In case of vertical dry storage, current numerical models are insufficiently validated against representative experiments, especially for turbulent flow of air in an annuli where usual turbulence modelling developed for forced convection flows are not well adapted to mixed convection flows. For these reasons, EDF, CEA and Framatome are currently carrying out a basic model qualification program, launched in 1998 the experimental loop for axial flow is called PROMETHEE. The main features of the experimental vessel are near a scale 1 canister: height 5 m, diameter 90 cm, air gap thickness 10 cm. Radiative thermal exchange between canister and containment vessel being essential to be well known, emissivity of the walls have been measured. Motion of air along the canister may be natural or modified using an external fan, the tests presented control the boundary conditions and investigate the effect of the electrical power supplied (from 5 kW to 20 kW), the input and output 3D effect and the efficiency of the external wind. During the steady state and transient experiment, temperature profile of walls and air are carried out. In parallel detailed 2D and 3D thermal hydraulics calculation with the tools of the different partners (EDF: Code-Saturne, Framatome: Star-cd and CEA: TRIO and FLOTRAN) have been submitted to the same boundary conditions. The Star-cd software is a general purpose code for fluid mechanics and thermal engineering. Full coupled convection - conduction - radiation heat transfers are modelled. A set of parametric calculations has been performed: Different mesh sizes and different turbulence models (variants of the standard k-epsilon model) have been investigated. From the benchmark, the experimental-calculation comparisons results of the profile temperature and flow pattern show a good agreement and the discrepancy specially when the power increases is analysed. The comparison with tests measurements led also to improve the modelling practices in problems involving such mixed convection flows. (authors)

  13. Beam experiment at TARN

    International Nuclear Information System (INIS)

    TARN is a storage ring of low energy ions (T sub(N) -- 10 MeV/u) constructed in 1979 to verify the feasibility of intensity multiplication proposed at NUMATRON project. The mean radius and maximum magnetic rigidity of the ring are 5.06 m and 11.8 kG.m, respectively. Magnet system based on a strong focusing FODO lattice is composed of 8 dipole and 16 quadrupole magnets. Additional 12 sextupole magnets are also installed for chromaticity control. Intensity increase by the multi-turn injection is 20 times with the dilution factor of 2.0 in horizontal transverse phase space. Injected beams are RF captured with the frequency around 8 MHz and moved inner side of the ring by RF deceleration as large as -- 5 % in ?p/p. Beam intensity increases linearly up to around 20 stackings with the capture efficiency of 80 % and 30 Hz repetition rate. Dilution factor of the longitudinal phase space is measured at 1.8. Thus about 300 times total intensity increase has been attained. The e-folding beam life time of 7 MeV proton is measured at 400 s for the vacuum pressure of 1 x 10-10 Torr. Stochastic momentum cooling experiment of 7 MeV proton has been performed. A feed-back system based on the 'Notch-Filter' method has been adopted for its simplicity and characteristics suitable for lower beam intensity. Cooling time for the 7 MeV proton beam with the intensity of 108 is estimated at 19 s for optimum cooling rate with the system gain of 105 dB, while the system gain as large as 111 dB has been achieved without self-oscillation of the electronics system. From the beam experiment, the cooling time of 108 proton beam with fractional momentum spread of 1.4 x 10-2 is measured at --20 sec with the system gain of 97 db. (author)

    The PIANO 3 inhalation device was used to expose Wistar SPF rats to NaH232PO4 and Ca3(32PO4)2 aerosol. The exposure lasted 60 minutes, the 32P activity in the aerosol was 5.61 kBq in one litre of air. The cardiac output of the rats was 178.9±42.9 ml. The deposition was measured with a whole-body counter for rats, the retained amount was determined from the volume activity of the aerosol, cardiac output and the time of exposure. From the inhaled amount of aerosol, the part deposited in the respiratory tract was 47.6%. Retention and excretion values were measured in the period of 0 to 7 days after the inhalation. Sodium salt was mainly excreted with urine in the first day (Es/Em=0.7570), calcium salt was mainly excreted with feces (Es/Em=2.31). The distribution of radioactivity in the respiratory tract, alimentary tract and other tissues was observed in the time intervals 0-6-24-72-168 hours after the exposure. Similar distribution was also shown after interavenous administration of radiophosphorus. General principles of management of inhalation experiments are discussed. (author). 3 figs., 2 tabs., 5 refs

    In order to conduct the shield design calculation of the Large Hadron Collider (LHC) under planning in CERN at present, the radiation group of CERN uses FLUKA (Monte Carlo High Energy Radiation Transport Code). Here is introduced on outline of FLUKA and use experience of FLUKA in the LHC-B detector shield design calculation in LHC plan. FLUKA can be said to be the highest standard in the high energy radiation transportation code of the world at every points of the physical model, the Monte Carlo calculation technique and the convenience at usage of the code. In Japan Atomic Energy Research Institute (JAERI), a using right of FLUKA for the target neutronics and facility shielding design at the neutron science research center is obtained and it seems to be an effective design means in these future designs. However, because FLUKA is allowed a limited opening and no own verification on the code, it will be supposed to be a large problem on investigating a validity in design. (K.G.)

  3. DSM - the Iowa experience

    International Nuclear Information System (INIS)

    The Iowa Legislature passed a landmark bill in the 1990 session which became effective July 1, 1990. This legislation had several components, the most significant being a requirement for rate-regulated utilities in Iowa to begin implementing energy efficiency program. The legislation sets spending targets of 2% of gross electric revenues and 1 1/2% of gross gas revenues. It also requires five specific program areas to be considered. Administrative rule making to comply with the legislation was completed in early 1991 and all utility plans were filed by July 1, 1991. The plans were reviewed in individual contested proceedings and most were approved by February 1, 1992. The final orders in all of the proceedings required the utilities to begin the programs in 1992. Iowa-Illinois Gas and Electric Company proposed and received approval on eight programs spanning all customer classes. Most of the programs include both gas and electric measures. The four residential programs were implemented on March 1, 1992 and the four commercial/industrial programs were implemented on April 1, 1992. Costs of the programs are deferred in special accounts until a contested cost recovery proceeding is convened. The legislation requires cost recovery from customers to lag the program implementation by at least two years. Therefore, those proceedings will commence in 1994 with amortization to be spread over four years following an order in that proceeding. The presentation will follow the sequence of the following charts as well as detail experience in the programs to date

    Last Monday, the new CERN Machine Advisory Committee (CMAC) met for the first time, and we had good news to tell its members. Over the weekend, injection tests for both LHC beams were successfully carried out. In other words, we’ve had beam in the LHC for the first time since September 2008. That’s a good feeling, but it’s no reason for complacency. There’s still a long way to go before first physics at the new energy frontier. As the Bulletin has reported over recent weeks, we’re gathering a lot of positive experience with the new quench detection and protection system (QPS), which is already allowing us to monitor the LHC far better than we were able to in the past. So far, the QPS for three of the LHC’s eight sectors has been put through its paces, and we’ve also power tested those sectors to 2000 amperes, the equivalent of around 1.2 TeV per beam. The next step is to slowly increase the current to 4000 amperes, and...

  6. Enthusiastic Teachers, Vivid Experiments

    ascination with materials and chemical change is a hallmark of chemists, and it is also an important pedagogical tool. A fringe benefit of editing JCE is that I encounter so many nice people who send interesting and helpful communications. One of the first of these to cross my desk this year was from E. J. Behrman, who recommended that I read and call to your attention "Brilliant Light: A Chemical Boyhood" by Oliver Sacks, noted neurologist and author. It appeared in the December 20, 1999, issue of The New Yorker and is well worth your time and effort to find and read. Sacks's reminiscence of his boyhood interest in chemistry is fascinating. His obvious love of our science is inspiring. And he has expressed both in words that are brilliantly chosen and a joy to read. In a profile of Sacks that appeared in Chemical and Engineering News (January 10, 2000), Madeleine Jacobs relates that he is writing a book on his boyhood encounters with chemistry (to be published by Alfred A. Knopf). I am looking forward to that with great anticipation. During 1999 he also wrote an article on the periodic table in the New York Times Magazine (April 18) and an op-ed piece on chemistry sets in the New York Times (May 13). In the latter he describes how hard it is these days for a nonchemist, especially a young one, to obtain chemicals to experiment with. Chemistry sets are not what they used to be! Sacks's writings contain important messages for all of us who teach chemistry and all who are involved in piquing students' interest in our subject. A brief excerpt from his New Yorker article illustrates my point. I knew zinc--the dull, slightly bluish birdbath in the garden was made of zinc--and tin, from the heavy tinfoil in which sandwiches were wrapped for a picnic. My mother showed me that when tin or zinc was bent it uttered a special "cry." "It's due to deformation of the crystal structure," she said, forgetting that I was five and could not understand her--and yet her words made me want to know more. Fascination with materials and chemical change is a hallmark of chemists, and it is also an important pedagogical tool. Real substances have very interesting properties--ones that can excite students and spur them to greater achievement. Sacks's writing is full of such fascinating factoids. It inspires me to try to use them much more effectively to help students develop the curiosity and commitment that will help them learn. Everyday things, such as the startling cold of a diamond engagement ring when it touches one's lips, can illustrate otherwise tiresome topics like thermal conductivity far better than a table of data. Sacks was fortunate that his parents, both physicians, had the means and took the time to show him interesting phenomena and respond to his many questions, as did two uncles. In addition, his father's office was in their home, providing a broad range of interesting substances and solutions that enhanced his curiosity and experience. Few of our students have had such opportunities before they come to us, but we can resolve that they should not leave our classes without seeing and experiencing real chemistry that grabs their attention and interest. If we are to do this, we must be familiar with lots of chemical phenomena and realize how they can be applied effectively in our classrooms and laboratories. And we need to know which of them are appropriate for students to observe and interact with without violating rules of good sense and chemical safety. That's no mean feat, especially if our own backgrounds are much less rich than was Sacks's childhood--an extremely likely possibility. Formal education is important, but it is unreasonable to expect that it can provide all the knowledge that would be useful to any of us in our teaching. And new chemistry is discovered every day. Learning more and more chemistry and improving our teaching skills are processes that continually require our attention and effort. I hope that JCE contributes in important ways to such professional development. My overriding goal for this Journal is to provide accurate, interesting, relevant information that can enhance chemistry teaching and learning. Your editorial staff organize the information so that access is as quick and easy as possible, and we try to make connections both by juxtaposition of articles in print and by linking information electronically. The latest example of this is being introduced this month. It is a new feature directed especially to busy high school chemistry teachers: the JCE High School Chemed Learning Information Center (JCE HS CLIC). In this special section of JCE Online we have collected and organized JCE's many articles that are of interest to high school teachers, aiming to provide the quickest, easiest access to the information. You can read more about it on page 536. We look forward to feedback from those who have tried CLIC and have suggestions for adding to it or otherwise improving it. When asked how children today could be weaned from the many distractions of modern life and turned on to chemistry, Oliver Sacks recommended, "Enthusiastic teachers, vivid experiments". I recommend that you read Sacks's article in the New Yorker to rejuvenate your enthusiasm and read JCE to find new, vivid experiments. The combination may be just what is needed to capture students' attention for the rest of this school year and to enhance learning for many years to come.

    The Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrinos (CAPTAIN) program is designed to make measurements of scientific importance to long-baseline neutrino physics and physics topics that will be explored by large underground detectors. The experiment employs two liquid Argon time projection chambers (LArTPCs), a primary detector with a mass of approximately 10 ton that will be deployed at different facilities for physics measurements and a two ton prototype detector for configuration testing. The physics programs for CAPTAIN include measuring neutron interactions at the Los Alamos Neutron Science Center, measuring neutrino interactions in the high-energy regime (1.5-5 GeV) at Fermilab NuMI beam, and measuring neutrino interactions in the low-energy regime (<50 MeV) at stopped pion sources for supernova neutrino studies. The prototype detector (Mini-CAPTAIN) has been commissioned and the first UV laser track has been seen in its TPC. This paper gives an overview of the CAPTAIN pr...

  8. Solar array flight experiment

    Science.gov (United States)

    1986-01-01

    Emerging satellite designs require increasing amounts of electrical power to operate spacecraft instruments and to provide environments suitable for human habitation. In the past, electrical power was generated by covering rigid honeycomb panels with solar cells. This technology results in unacceptable weight and volume penalties when large amounts of power are required. To fill the need for large-area, lightweight solar arrays, a fabrication technique in which solar cells are attached to a copper printed circuit laminated to a plastic sheet was developed. The result is a flexible solar array with one-tenth the stowed volume and one-third the weight of comparably sized rigid arrays. An automated welding process developed to attack the cells to the printed circuit guarantees repeatable welds that are more tolerant of severe environments than conventional soldered connections. To demonstrate the flight readiness of this technology, the Solar Array Flight Experiment (SAFE) was developed and flown on the space shuttle Discovery in September 1984. The tests showed the modes and frequencies of the array to be very close to preflight predictions. Structural damping, however, was higher than anticipated. Electrical performance of the active solar panel was also tested. The flight performance and postflight data evaluation are described.

  9. Particle physics experiments, 1991

    International Nuclear Information System (INIS)

    Data taking for this experiment was completed in December 1983. The samples include approximately 19,000 (ν) and 11,000 (ν-bar) charged current events. These constitute the largest data set of interactions on free protons. Work published to date includes studies of inclusive structure functions and final state properties, exclusive final states, neutral current cross sections and production of strange and charmed particles. During the past year results have been published on the production of f2 (1270) and ν0 (770) mesons in ρp and ρ-barp charged current interactions. In the case of the f2 this represents the first observation of such production. It is found that the multiplicities are 0.047±0.017 in ρp and 0.17±0.018 in ρ-barp. The f2 mesons are mostly produced at large hadronic invariant mass W and in the forward hemisphere. The production of ν0 mesons can be observed with high statistics in both ρp and ρ-barp interactions and the differential cross section studied. The observations are compared with LUND Monte Carlo predictions, which are generally found to be too high. However qualitative features of the data are reproduced. Work continues on a precise determination of the neutral current/charged current ratio, on the study of charged and neutral current structure functions and on the production of strange particles.

  10. Beam and experiments: summary

    International Nuclear Information System (INIS)

    The discovery of neutrino oscillations marks a major milestone in the history of neutrino physics, and opens a new window to the still mysterious origin of masses and flavour mixing. Many current and forthcoming experiments will answer open questions; however, a major step forward, up to and possibly including CP violation in the neutrino-mixing matrix, requires the neutrino beams from a neutrino factory. The neutrino factory is a new concept for producing neutrino beams of unprecedented quality in terms of intensity, flavour composition, and precision of the beam parameters. Most importantly, the neutrino factory is the only known way to generate a high-intensity beam of electron neutrinos of high energy. The neutrino beam from a neutrino factory, in particular the electron-neutrino beam, enables the exploration of otherwise inaccessible domains in neutrino oscillation physics by exploiting baselines of planetary dimensions. Suitable detectors pose formidable challenges but seem within reach with only moderate extrapolations from existing technologies. Although the main physics attraction of the neutrino factory is in the area of neutrino oscillations, an interesting spectrum of further opportunities ranging from high-precision, high-rate neutrino scattering to physics with high-intensity stopped muons comes with it

  11. Operating experience at CEBAF

    International Nuclear Information System (INIS)

    CEBAF, the Continuous Electron Beam Accelerator Facility, is a 5-pass, recirculating, superconducting rf linac designed to provide exceptional beam quality at 4 GeV up to 200 ?A CW. It is made up of an injector, two 400-MeV linacs, and 9 recirculation arcs having a total beamline length of more than 4.5 km. On Nov. 5, 1995, CEBAF delivered a 4 GeV, 25-?A CW electron beam to the first of 3 experimental halls and the experimental physics program was started 10 days later. Accelerator availability during the first month of the experimental run exceeded 75%. Beam properties measured in the experimental hall to date are a one sigma momentum spread of 5x10-5 and an rms emittance of 0.2 nanometer-radians, better than design specification. CW beam has been provided from all 5 passes at 800 MeV intervals. Outstanding performance of the superconducting linacs suggests a machine energy upgrade to 6 GeV in the near term with eventual machine operation at 8-10 GeV. Results from commissioning and operations experience since the last conference are presented

  12. Condensed landscape experience

    DEFF Research Database (Denmark)

    Earon, Ofri

    ‘Re-thinking interaction between landscape and urban buildings’ participates in an interdisciplinary discourse about the theoretical and practical advantages of openly juxtaposing landscape and architecture without having one more advanced in importance. Recently, the greenification of buildings is becoming a standard in contemporary architecture. Merging architecture and landscape has turned into a principle for an ecological / sustainable architecture. Yet, my aspiration is to achieve a wider interaction involving an application of a wider range of perspectives, such as: urban identity, social demands, quality of space, mixture of functions, urban complexity, public life and cultural heritage. In order to launch such an approach, an understanding of the spatial, social and environmental significance of a radical re-thinking of relationships between architecture and landscape is necessary. This paper addresses the question of whether the sensation of landscape can be condensed in function or to the size of an urban building. It also discusses the benefits and potentials of the amalgamate, by underlining the unique qualities of such a hybrid. In an attempt to define the experience of landscape, eight attributes are introduced: discover, diversity, cyclic, equality, scale, transformation, topography and wilderness. The essay analyzes the attendance of these attributes in two existing fascinating hybrid structures. The first example is The High-Line a public space in New York, and the second example is Dubiner Apartment House in Israel. Even though the examples are rather different one from the other, they embody a beneficial exchange of architectural and landscape features.

  13. Subterranean stress engineering experiments

    International Nuclear Information System (INIS)

    The state of stress in a subterranean rock mass has classically been assumed to be constant at best. In soil with a high clay content, preconsolidation and drainage methods can lead to more stable foundation material, but methods for engineering the stresses in large masses of rock are not well known. This paper shows the results from an experiment designed to alter the in situ rock stress field in an oil shale mine. This was done by hydrofracturing the rock by use of a packed-well injection system and then propping the crack open with a thixotropic gel, which slowly hardened to the consistency of cement. Successive hydrofracture and high-pressure grouting resulted in an overstressed region. Well-head injection pressures, surface tilts, injection rates, and subterranean strains were measured and recorded on floppy disk by a Z-80 microprocessor. The results were then transmitted to the large computer system at the Los Alamos Scientific Laboratory (LASL). To put the data in a more useful form, computer-generated movies of the tilts and strains were made by use of computer graphics developed at LASL. The purpose of this paper is to present results from the Single Large Instrumented Test conducted in the Colony Oil Shale Mine near Rifle, Colorado. 13 figures

    Cosmic ray particles hit the Earth's atmosphere and induce extensive air showers (EAS). These EAS mainly consist of electrons and positrons that produce radio emission due to their interaction with the Earth's magnetic field. Measuring this radio emission is the purpose of the LOPES (LOFAR Prototype Station) experiment. LOPES is located at Campus North of the Karlsruhe Institute of Technology at the same site as the EAS particle detector KASCADE-Grande. Since the first measurements in 2003, LOPES was improved by various experimental setups and could establish the radio technique. By now, detailed studies of the measured radio signal are performed, like the behaviour of the lateral distribution or the polarization of the electric field. Furthermore, with LOPES the dependence of the radio pulse on properties of the incoming cosmic ray, like primary energy, primary mass, or incoming direction is investigated. In this article we describe the different LOPES setups, next we explain our standard analysis procedure and then we discuss some highlights of our recent results.

  16. My experience in arbitration

    Directory of Open Access Journals (Sweden)

    Claude Witz

    2011-12-01

    Full Text Available This paper deals with the nature of arbitration as one of the alternatives in dispute resolution processes different from mediation and conciliation, and obviously, from judicial adjudication. Unlike a mediator or a conciliator, an arbitrator is empowered to pass a judgement, like a court. In other words, the arbitrator will render a decision which is binding for the parties. The arbitrator has the jurisdictio, like a judge. Although the office of a judge and an arbitrator is the same, the source of their power is different. The judge’s power originates from a State, whereas the power of the arbitrator results primarily from a contract. Unlike the court, the arbitrator lacks the imperium, i.e. the power to make the award enforceable. When a party refuses to enforce the award, enforceability can only be provided by the judge or an authority of the state where the award has to be enforced. In a certain sense the state thus provides the back up for the arbitration system. This paper presents personal thoughts drawn from the author’s professional experience as an arbitrator in Franco-German disputes.

  17. Terawatt fiber pinch experiments

    International Nuclear Information System (INIS)

    Pinch formation in fiber pinch experiments has been investigated in the lower terawatt regime. The main results are: (1) there are upper limits of breakdown voltage (?700 kV) and current rise rate (?20 kA/ns) beyond which leak discharges develop within the vacuum feed of the pulseline KALIF; (2) there is a lower limit of fiber radius (?10 ?m) below which pinch disruptions take place at a pinch current of >300 kA; (3) the hot (Te?1 keV) inhomogeneous pinch plasma develops typically 10 ns after local collapses (micropinches) at a pinch current >400 kA and lives for more than 50 ns; (4) neutron emission (yield of CD2 fibers ?1010) appears mostly isotropic; (5) all fiber pinches show global expansion with velocities reaching from typically 10 ?m/ns (initial expansion) to >100 ?m/ns; and (6) the power requirements for the fiber ablation process are contradictory to those for the final pinch phase

    Full Text Available Phishing is a method that hackers use to fraudulently acquire sensitive or private information from a victimby impersonating a real entity [1]. Phishing can be defined as the act of soliciting or stealing sensitiveinformation such as usernames, passwords, bank account numbers, credit card numbers, and socialsecurity or citizen ID numbers from individuals using the Internet [2]. Phishing often involves some kindof deception. The results from a study of Jagatic et al. (2007 indicate that Internet users are four timesmore likely to become phishing victims if they receive a request from someone appearing to be a knownfriend or colleague. The Anti-Phishing Work Group indicates that at least five percent of users respondedto phishing scams and about two million users gave away their information to spoofed websites [3]. Thisresults in direct losses of $1.2 billion for banks and credit card companies (Dhamija, 2006.In order to understand how phishing can be conducted, the researcher set up a phishing experiment inone of Thailand’s higher education institutions. The subjects were MBA students. A phishing email wassent to the subjects, and the message led the subject to visit the phishing website. One hundred seventystudents became victims. The data collection included a survey, an interview, and a focus group. Theresults indicated that phishing could be easily conducted, and the result can have a great impact on thesecurity of an organization. Organizations can use and apply the lessons learned from this study toformulate an effective security policy and security awareness training programs.

  3. Design of Computer Experiments

    DEFF Research Database (Denmark)

    Dehlendorff, Christian

    2010-01-01

    The main topic of this thesis is design and analysis of computer and simulation experiments and is dealt with in six papers and a summary report. Simulation and computer models have in recent years received increasingly more attention due to their increasing complexity and usability. Software packages make the development of rather complicated computer models using predefined building blocks possible. This implies that the range of phenomenas that are analyzed by means of a computer model has expanded significantly. As the complexity grows so does the need for efficient experimental designs and analysis methods, since the complex computer models often are expensive to use in terms of computer time. The choice of performance parameter is an important part of the analysis of computer and simulation models and Paper A introduces a new statistic for waiting times in health care units. The statistic is a measure of the extent of long waiting times, which are known both to be the most bothersome and to have the greatest impact on patient satisfaction. A simulation model for an orthopedic surgical unit at a hospital illustrates the benefits of using the measure. Another important consideration in connection to simulation models is the design of experiments, which is the decision of which of the possible configurations of the simulation model that should be tested. Since the possible configurations are numerous and the time to test a single configuration may take minutes or hours of computer time, the number of configurations that can be tested is limited. Papers B and C introduce a novel experimental plan for simulation models having two types of input factors. The plan differentiates between factors that can be controlled in both the simulation model and the physical system and factors that are only controllable in the simulation model but simply observed in the physical system. Factors that only are controllable in the simulation model are called uncontrollable factors and they correspond to the environmental factors in fluencing the physical system. Applying the experimental framework on the simulation model in Paper A shows that the effects of changes in the uncontrollable factors are better understood with the proposed design compared to the alternative and commonly used methods. In papers D and E a modeling framework for analyzing simulation models with multiple noise sources is presented. It is shown that the sources of variation of the simulation model can be divided in two components corresponding to changes in the environmental factors (the uncontrollable factor settings) and to random variation. Moreover, the structure of the environmental effects can be estimated, which can be used to put the system in a more robust operating mode. The interpolation technique called Kriging is the topic of Paper F, which is a widely applied technique for building so called models-for-the-model (metamodels). We propose a method that handles both qualitative and quantitative factors, which is not covered by the standard model. Fitting the final Kriging model is done in two stages each based on fitting regular Kriging models. It is shown that this method works well on a realistic example such as a simulation model for a surgical unit.

  4. Mapping bicyclists’ experiences in Copenhagen

    2013-01-01

    This paper presents an approach to the collection, mapping, and analysis of cyclists’ experiences. By spatially relating located experiences to the availability of bicycle facilities and other aspects of the urban environment, their influence on cyclists’ experiences can be analysed. 398 cyclists responded and sketched their most recent cycle route and a total of 890 points to locations along the route where they had had positive and negative cycling experiences. The survey was implemented as an online questionnaire built on Google Maps, and allowed up to three positive and three negative experience points to be mapped and classified.By relating the characteristics of the experience points and the routes to the traversed urban area in general, the significance of the preconditions for obtaining positive or negative experiences could be evaluated. Thereby urban spaces can be mapped according to the potential promotion of positive or negative experiences. Further, the method might be applied to assess the effect of proposed changes to the urban design in terms of cyclists’ experiences.Statistical analysis of the location attributes, traffic environments and conflicts, bicycle facilities, urban density, centrality, and environmental amenities indicates that positive experiences, or the absence of negative experiences, are clearly related to the presence of en-route cycling facilities, and attractive nature environments within a short distance of large water bodies or green edges along the route.

  6. Regulatory and operating experience

    International Nuclear Information System (INIS)

    Regulatory and operating experience in the disposal of radioactive waste can be divided into three time periods, World War II and its aftermath, Post World War II till the end of the cold war, and crystal ball gazing into the future. In the first period, there was little regulatory guidance and operating practices, all conducted under wartime secrecy conditions, sometimes were not even up to the norms of the times. Environmental releases resulted in some seriously contaminated sites and high dosages to some offsite populations. Failure to consider even the storage of wastes in a systems context resulted in some stocks that were difficult to recover, treat and dispose of in a final manner. In the second period, increasing civilian uses of nuclear power and isotopes for medical, research, and industrial purposes and military pressure for increased production of Pu-239 resulted in large and more dispersed disposal of radioactive wastes. Regulatory regimes, following growing environmental consciousness, came into existence that minimized exposure to environmental contamination. Practices, in most instances, increasingly conformed to these regulatory demands. The future is unknowable. However, for high level wastes, except for thermodynamically stable forms, no technology can guarantee safety and present methodologies are calculated to produce doses orders of magnitude lower than regulatory limits. Therefore, it is possible that research will be limited to no higher technology than is reasonably achievable. Whereas for low level waste, where proof is practicably possible, as high technology as is reasonably achievable will be best in the long run. (author). 24 refs, 5 figs, 3 tabs

  7. GNF2 Operating Experience

    International Nuclear Information System (INIS)

    GNF's latest generation fuel product, GNF2, is designed to deliver improved nuclear efficiency, higher bundle and cycle energy capability, and more operational flexibility. But along with high performance, our customers face a growing need for absolute fuel reliability. This is driven by a general sense in the industry that LWR fuel reliability has plateaued. Too many plants are operating with fuel leakers, and the impact on plant operations and operator focus is unacceptable. The industry has responded by implementing an INPO-coordinated program aimed at achieving leaker-free reliability by 2010. One focus area of the program is the relationship between fuel performance (i.e., duty) and reliability. The industry recognizes that the right balance between performance and problem-free fuel reliability is critical. In the development of GNF2, GNF understood the requirement for a balanced solution and utilized a product development and introduction strategy that specifically addressed reliability: evolutionary design features supported by an extensive experience base; thoroughly tested components; and defense-in-depth mitigation of all identified failure mechanisms. The final proof test that the balance has been achieved is the application of the design, initially through lead use assemblies (LUAs), in a variety of plants that reflect the diversity of the BWR fleet. Regular detailed surveillance of these bundles provides the verification that the proper balance between performance and reliability has been achieved. GNF currently has GNF2 lead use assemblies operating in five plants. Included are plants that have implemented extended power up-rates, plants on one and two-year operating cycles, and plants with and without NobleChemTM and zinc injection. The leading plant has undergone three pool-side inspections outages to date. This paper reviews the actions taken to insure GNF2's reliability, and the lead use assembly surveillance data accumulated to date to validate the adequacy/expected behavior of the design. (authors)

    I have had the opportunity to support the analytical laboratories in chemical analysis of unknown samples, using Optical Microscopy (OM), Polarizing Light Microscopy (PLM), Fourier-Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEMEDS), and X-ray Powder Diffraction (XPD). I have assisted in characterizing fibers pulled from a spacecraft, a white fibrous residue discovered in a jet refueler truck, brown residue from a plant habitat slated for delivery to the ISS (International Space Station), corrosion on a pipe from a sprinkler, and air filtration material brought back from the ISS. I also conducted my own fiber study in order to practice techniques and further my understanding of background concepts. Furthermore, I had the opportunity to participate in diverse work assignments, where I was assigned to work with other branches of the engineering department for 1-2 days each. The first was in the Materials Science branch where I participated in the construction of the plant habitat intended for use in research aboard the ISS. The second was in the Testing Design branch where I assisted with tensile and hardness testing of over 40 samples. In addition, I have had the privilege to attend multiple tours of the NASA KSC campus, including to the Astronaut Crew Quarters, the VAB (the main area, the Columbia room, and the catwalk), the Visitor Center housing the shuttle Atlantis, the Saturn-V exhibit, the Prototype laboratory, SWAMP WORKS, the Shuttle Landing Facility, the Crawler, and the Booster Fabrication Facility (BFF). Lastly, much of my coursework prepared me for this experience, including numerous laboratory courses with topics diverse as chemistry, physics, and biology.

  9. The isotope correlation experiment

    International Nuclear Information System (INIS)

    The ESARDA working group on Isotopic Correlation Techniques, ICT and Reprocessing Input Analysis performed an Isotope Correlation Experiment, ICE with the aim to check the feasibility of the new technique. Ten input batches of the reprocessing of the KWO fuel at the WAK plant were analysed by 4 laboratories. All information to compare ICT with the gravimetric and volumetric methods was available. ICT combined with simplified reactor physics calculation was included. The main objectives of the statistical data evaluation were detection of outliers, the estimation of random errors and of systematic errors of the measurements performed by the 4 laboratories. Different methods for outlier detection, analysis of variances, Grubbs' analysis for the constant-bias model and Jaech's non-constant-bias model were applied. Some of the results of the statistical analysis may seem inconsistent which is due to the following reasons. For the statistical evaluations isotope abundance data (weight percent) as well as nuclear concentration data (atoms/initial metal atoms) were subjected to different outlier criteria before being used for further statistical evaluations. None of the four data evaluation groups performed a complete statistical data analysis which would render possible a comparison of the different methods applied since no commonly agreed statistical evaluation procedure existed. The results prove that ICT is as accurate as conventional techniques which have to rely on costly mass spectrometric isotope dilution analysis. The potential of outlier detection by ICT on the basis of the results from a single laboratory is as good as outlier detection by costly interlaboratory comparison. The application of fission product or Cm-244 correlations would be more timely than remeasurements at safeguards laboratories

  10. DIRAC Experiment at CERN

    International Nuclear Information System (INIS)

    The strong interaction dynamics is still not fully understood within the Standard Model (SM) of elementary particles. Quantum Chromodynamics (QCD), describing the strong interaction part of the SM, has successfully been tested, but only in the perturbative region of large momentum transfer. In the nonperturbative region of QCD, Chiral Perturbation Theory (ChPT) seems to be the candidate theory for low momentum processes, exploiting the mechanism of spontaneous breakdown of chiral symmetry. Precise predictions of ChPT have so far not been tested experimentally at an equivalent accuracy level. DIRAC experiment aims to measure accurately the ππ s-wave scattering lengths at very low momentum transfer. This should be achieved by measuring the lifetime of the π+ π- exotic atom (A2π). For the first time, experimental evidence in favour of or against the existence of a strong quark condensate in the QCD vacuum, could be within reach. The experimental setup has been installed at the 24 GeV Proton Synchrotron of CERN. All the detectors were tuned and used for physical data taking in 1999. The trigger selects coincidences of particles in the two spectrometer arms. In order to accumulate π+ π- pairs from ionized A2π atoms, the multi-level trigger accepts predominantly pion pairs with small relative momentum (MeV/c region). The proton interaction with a Ni (100 μm) target has been used as pion source for A2π production. Preliminary analysis of the experimental data has shown good detector performance (alignment, calibration, resolution): - calibration by Λ mass measurement (mΛ = 1115.6 MeV/c2 with a Λ-peak width σ = 0.92 MeV/c2); - momentum resolution (σp∼6.5 x 10-3); - relative momentum resolution (σQ ∼2.7 MeV/c); - evidencing the Coulomb correlated π+π- pairs with low relative momentum.

  11. An emergency exercise experience

    International Nuclear Information System (INIS)

    Emergency exercises are held to satisfy regulatory requirements and to hopefully improve emergency response. Unfortunately, simply satisfying the requirement is often the principle concern of those who plan drills. Argonne National Laboratory has detailed emergency plans, and each Division is required to have an emergency exercise at least once each year. However, the pressure to minimize time taken from research efforts reduces the value of many exercises. During the past year, the Health Physics Section at ANL made an effort to optimize the information and training obtained in the time allotted for a drill. The purpose of this presentation is to share our approach and the results of one experience with the anticipation that it will stimulate others to critically look at emergency exercises in their organizations. To be of value, an emergency response exercise must have clear objectives, allow organized reporting, contain a documented follow-up critique, and provide for correction of deficiencies in training and in the emergency plan. A mock criticality incident at ANL was used to test specific emergency response capabilities. The objectives of the 45 minute exercise included testing: (1) how well Health Physics, Fire Department, and Medical personnel would deal with the unexpected find of an unconscientious, contaminated person in a high radiation field; (2) the capability to quickly predict environmental radioactivity concentration for a surprise mock stack release of fission products; (3) the time required and accuracy for dose assessment from personnel dosimeters, criticality dosimeters and samples of blood and hair which were irradiated to known doses in the Argonne Janus reactor; (4) how well Health Physics personnel would identify and sort 'exposed persons' who had no dosimeters (small radioactive sources were hidden on select persons); and (5) how persons from the evacuated building would be accounted for. As a result of findings, special Health Physics training on criticality was provided and support capabilities are being refined. (author)

  12. Physical experience enhances science learning.

    Science.gov (United States)

    Kontra, Carly; Lyons, Daniel J; Fischer, Susan M; Beilock, Sian L

    2015-06-01

    Three laboratory experiments involving students' behavior and brain imaging and one randomized field experiment in a college physics class explored the importance of physical experience in science learning. We reasoned that students' understanding of science concepts such as torque and angular momentum is aided by activation of sensorimotor brain systems that add kinetic detail and meaning to students' thinking. We tested whether physical experience with angular momentum increases involvement of sensorimotor brain systems during students' subsequent reasoning and whether this involvement aids their understanding. The physical experience, a brief exposure to forces associated with angular momentum, significantly improved quiz scores. Moreover, improved performance was explained by activation of sensorimotor brain regions when students later reasoned about angular momentum. This finding specifies a mechanism underlying the value of physical experience in science education and leads the way for classroom practices in which experience with the physical world is an integral part of learning.

    The criteria for the selection of the experimental areas and individual experiments were that the experiment or area must make a meaningful contribution to the field of material science and that the space environment was either an absolute requirement for the successful execution of the experiment or that the experiment can be more economically or more conveniently performed in space. A number of experimental areas and individual experiments were recommended for further consideration as space experiments. Areas not considered to be fruitful and others needing additional analysis in order to determine their suitability for conduct in space are also listed. Recommendations were made concerning the manner in which these materials science experiments are carried out and the related studies that should be pursued.

    This paper describes the wall catalysis experiment which is planned as part of the Aeroassist Flight experiments (AFE) that will be flown from the Space Shuttle Orbiter in late 1993. Research on candidate high-catalytic efficiency overcoats for the experiment conducted in an arc-jet air stream are discussed. The temperature distribution over the AFE heat shield is also predicted using a reacting boundary layer solution that includes surface kinetics and optical properties determined from these tests.

  15. Safety experiments and fire extinction experiments with alkali metals

    International Nuclear Information System (INIS)

    In addition to experimental runs with test facilities, fire extinction experiments are performed routinely with open spill-catchpans. Certain safety aspects of the high temperature test facility HT 3 as well as a different behaviour of Sodium and Potassium fires necessitated the realization of fire extinction experiments with a more exact problem definition. The report gives a description of the test facilities and the experiments performed. (Author)

  16. Overview of LHD experiments

    International Nuclear Information System (INIS)

    Experimental studies on the Large Helical Device during the last two years are reviewed. After the start of LHD experiment in 1998, the magnetic field has been gradually raised up to 2.89 T. The heating power has been increased, up to 4.2 MW for NBI, 1.3 MW for ICRF, and 0.9 MW for ECRH. Upgrading the key hardware systems has led to the extension of the plasma parameters to (i) higher Te [Te(0)=4.4 keV at =5.3x1018m-3 and Pabs=1.8MW], (ii) higher confinement [?E=0.3 s, Te(0)=1.1 keV at =6.5x1019m-3 and Pabs=2.0MW] and (iii) higher stored energy Wpdia=880kJ. High performance plasmas have been realized in the inward shifted magnetic axis configuration (R=3.6m) where the helical symmetry is recovered and the particle orbit properties are improved by trade off of MHD stability properties due to the appearance of the magnetic hill. The energy confinement was systematically higher than that predicted by the International Stellerator Scaling 95 up to a factor of 1.6 and was comparable with ELMy H-mode confinement capability in tokamaks. This confinement improvement is attributed to the configuration control (the inward shift of magnetic axis) and to the formation of the high edge temperature. The achieved average beta value reached 2.4% at B=1.3 T, the highest beta value ever obtained in helical devices, and so far no degradation of confinement by MHD phenomenon is observed. The inward shifted configuration has also led to successful ICRF minority ion heating. ICRF power up to 1.3 MW was reliably injected into the plasma without significant impurity contamination and a plasma with a stored energy of 200 kJ was sustained for 5 sec by ICRF alone. As another important result long pulse discharges of more than 1 minute were successfully achieved separately with NBI heating of 0.5 MW and with ICRF heating of 0.85 MW. (author)

  17. Brain and conscious experience.

    Science.gov (United States)

    Gazzaniga, M S

    1998-01-01

    There is a deep belief that we can attain not only a neuroscience of consciousness but a neuroscience of human consciousness. It is as if something terribly new and complex happens as the brain enlarges to its human form. Whatever this is, it triggers our capacity for self-reflection, for ennui, and for lingering moments, I would like to propose a simple, three-step suggestion. First, we should focus on what we mean when we talk about conscious experience. It is merely the awareness we have of our capacities as a species, but not the capacities themselves--only the awareness or feelings we have about them. The brain is clearly not a general purpose computing device but is a collection of circuits devoted to quite specific capacities. This is true for all brains, but what is wonderful about the human brain is that we have untold numbers of these capacities. We have more than the chimp, which has more than the monkey, which has more than the cat, which runs circles around the rat. Because we have so many specialized systems and because they can frequently do things they were not designed to do, it appears our brains have a single, general computing device. But we do not. Thus, step 1 requires that we recognize we are a collection of adaptations and, furthermore, we recognize the distinction between a species' capacities and its feelings about those capacities. Now consider step 2. Can there be any doubt that a rat at the moment of copulation is as sensorially fulfilled as a human? Of course it is. Do you think a cat does not enjoy a good piece of cod? Of course it does. Or, a monkey does not enjoy a spectacular swing? Again, it has to be true. Each species is aware of its special capacities. So, what is human consciousness? It is the very same awareness, save for the fact that we can be aware of so much more, so many wonderful things. A circuit--perhaps a single system or one duplicated over and over again--is associated with each brain capacity. The more systems a brain possesses, the greater the awareness of capacities. Think of the variations in capacity within our own species; they are not unlike the vast differences between species. Years of split-brain research have informed us that the left hemisphere has many more mental capacities than the right one. The left is capable of logical feats that the right hemisphere cannot manage. Although the right has capacities such as facial recognition systems, it is a distant second with problem-solving skills. In short, the right hemisphere's level of awareness is limited. It knows precious little about a lot of things, but the limits to human capacity are everywhere in the population. No one need be offended to realize that just as someone with normal intelligence can understand Ohm's law, others, like yours truly, are clueless about Kepler's laws. I am ignorant about them and will remain so. I am unable to be aware about what they mean for the universe. The circuits that enable me to understand these things are not present in my brain. By emphasizing specialized circuits that arise from natural selection, we see that the brain is not a unified neural net that supports a general problem-solving device. With this being understood, we can concentrate on the possibility that smaller, more manageable circuits produce awareness of a species' capacities. Holding fast to the notion of a unified neural net means we can understand human conscious experience only by figuring out the interactions of billions of neurons. That task is hopeless. My scheme is not. Hence step 3. The very same split-brain research that exposed shocking differences between the two hemispheres also showed that the human left hemisphere has the interpreter. The left brain interpreter's job is to interpret our behavior and our responses, whether cognitive or emotional, to environmental challenges. It constantly establishes a running narrative of our actions, emotions, thoughts, and dreams. It is the glue that keeps our PMID:9709824

  18. OSMOSE experiment representativity studies.

    Energy Technology Data Exchange (ETDEWEB)

    Aliberti, G.; Klann, R.; Nuclear Engineering Division

    2007-10-10

    The OSMOSE program aims at improving the neutronic predictions of advanced nuclear fuels through measurements in the MINERVE facility at the CEA-Cadarache (France) on samples containing the following separated actinides: Th-232, U-233, U-234, U-235, U-236, U-238, Np-237, Pu-238, Pu-239, Pu-240, Pu-241, Pu-242, Am-241, Am-243, Cm-244 and Cm-245. The goal of the experimental measurements is to produce a database of reactivity-worth measurements in different neutron spectra for the separated heavy nuclides. This database can then be used as a benchmark for integral reactivity-worth measurements to verify and validate reactor analysis codes and integral cross-section values for the isotopes tested. In particular, the OSMOSE experimental program will produce very accurate sample reactivity-worth measurements for a series of actinides in various spectra, from very thermalized to very fast. The objective of the analytical program is to make use of the experimental data to establish deficiencies in the basic nuclear data libraries, identify their origins, and provide guidelines for nuclear data improvements in coordination with international programs. To achieve the proposed goals, seven different neutron spectra can be created in the MINERVE facility: UO2 dissolved in water (representative of over-moderated LWR systems), UO2 matrix in water (representative of LWRs), a mixed oxide fuel matrix, two thermal spectra containing large epithermal components (representative of under-moderated reactors), a moderated fast spectrum (representative of fast reactors which have some slowing down in moderators such as lead-bismuth or sodium), and a very hard spectrum (representative of fast reactors with little moderation from reactor coolant). The different spectra are achieved by changing the experimental lattice within the MINERVE reactor. The experimental lattice is the replaceable central part of MINERVE, which establishes the spectrum at the sample location. This configuration leads to a uniform well-behaved system so that the reactor configuration is in the fundamental mode. In fact, an important property of the oscillation experiments performed in the OSMOSE program is that the neutron flux at the sample location has reached the asymptotic fundamental mode of the MINERVE lattice. This property allows the use of simple spatial methods for the analysis (e.g. a lattice code with axial buckling representing the leakage), without loss of accuracy. The computational challenge is then reduced to the need of an appropriate cross-section processing and of accurate resonance shielding algorithms. In the present study, calculations have been performed to investigate the similarity of the flux spectra at the sample position of different OSMOSE configurations with the neutron energy distributions characterizing existing thermal and fast reactors proposed under the advanced reactor programs Gen-IV, GNEP and NGNP.

  19. Evaluation of the DHCE Experiment

    2002-03-31

    The Dynamic Helium Charging Experiment (DHCE) experiment was conducted in the Fast Flux Test Facility (FFTF) during cycle 12, which was completed in 1992. The purpose of the experiment was to enhance helium generation in vanadium alloys to simulate fusion reactor helium-to-dpa ratios with a target goal of 4-5 appm He/dpa. The Fusion Materials Science Program is considering mounting another experiment in hopes of gathering additional data on the effect of helium on the mechanical and physical properties of vanadium structural materials. Pacific Northwest National Laboratory was assigned the task of evaluating the feasibility of conducting another DHCE experiment by carefully evaluating the results obtained of the first DHCE experiment. This report summarizes the results of our evaluation and presents recommendations for consideration by the Materials Science Coordinators Organization.

    In this paper we present the Experiment Dashboard monitoring system, which is currently in use by four Large Hadron Collider (LHC)[1] experiments. The goal of the Experiment Dashboard is to monitor the activities of the LHC experiments on the distributed infrastructure, providing monitoring data from the virtual organization (VO) and user perspectives. The LHC experiments are using various Grid infrastructures (LCG[2]/EGEE[3], OSG[4], NDGF[5]) with correspondingly various middleware flavors and job submission methods. Providing a uniform and complete view of various activities like job processing, data movement and publishing, access to distributed databases regardless of the underlying Grid flavor is the challenging task. In this paper we will describe the Experiment Dashboard concept, its framework and main monitoring applications.

  1. Data analysis for electronic experiments

    International Nuclear Information System (INIS)

    In this lecture I schell attempt to cover the principal off-line software aspects in electronic experiments. Of course, this is too ambitious an undertaking for two reasons: Firstly the field is vast, and some important aspect will certainly have escaped my attention. Secondly, the choice of methods, features, algorithms, and packages presented will be biased through my personal opinion and experience, although to some extent it is influenced as well by the opinion and experience of my colleagues, who, like myself, are working in this field at CERN. Therefore, beware. Whenever I shall claim something to be evident, a matter of experience -- a fact --it ain't necessarily so. On the other hand, it will not be entirely wrong, since our experience is based on something like 30 experiments in high-energy physics using electronic for other people, and although these people are of course misled, one has to admit their existence.

    The use of volunteers is becoming more visible and important in the experience economy also in the light of the financial crisis. From a management perspective within both public and private organizations the use of volunteers is an important element partly because they strengthen the brand and...... economy volunteers create a new set of dimensions, because they shift between being part of the experience producer and being one of the experience consumers. Volunteers are becoming increasingly more important in the experience economy as they contribute to the overall experience for users or customers...... and in the creation of communities related to the organizations. Within academics a holistic and a cross theory approach to the use of volunteers has largely been neglected. In industry or more precisely in cultural projects there is a lot of learning-by-doing experience, but it is often not written...

    Unlike the other large barrel-like experiments at the LHC, the LHCb detector consists of a series of large wall-like sub-detectors. The proton beams will collide at one end of the experiment hall and the detector will observe particles produced which travel close to the axis of the beam. This experiment will observe the production and subsequent decay of bottom quarks to look for rare 'CP violating' processes.

Ontologies are required to achieve this objective. A few subject-specific ontologies of experiments currently exist. However, despite the unity of scientific experimentation, no general ontology of experiments exists. We propose the ontology EXPO to meet this need.

In this short note, we describe classes of short baseline neutrino oscillation experiments and their goals.

  1. Experiment prediction for Loft Nonnuclear Experiment L1-4

    International Nuclear Information System (INIS)

    A computer analysis, using the WHAM and RELAP4 computer codes, was performed to predict the LOFT system thermal-hydraulic response for Experiment L1-4 of the nonnuclear (isothermal) test series. Experiment L1-4 will simulate a 200 percent double-ended offset shear in the cold leg of a four-loop large pressurized water reactor. A core simulator will be used to provide a reactor vessel pressure drop representative of the LOFT nuclear core. Experiment L1-4 will be initiated with a nominal isothermal primary coolant temperature of 282.20C, a pressurizer pressure of 15.51 MPa, and a primary coolant flow of 270.9 kg/s. In general, the predictions of saturated blowdown for Experiment Ll-4 are consistent with the expected system behavior, and predicted trends agree with results from Semiscale Test S-01-4A, which simulated the Ll-4 experiment conditions

  2. DHS Research Experience Summary

    Energy Technology Data Exchange (ETDEWEB)

    Venkatachalam, V

    2008-10-24

    I learned a great deal during my summer internship at Lawrence Livermore National Laboratory (LLNL). I plan to continue a career in research, and I feel that my experience at LLNL has been formative. I was exposed to a new area of research, as part of the Single Particle Aerosol Mass Spectrometry (SPAMS) group, and I had the opportunity to work on projects that I would not have been able to work on anywhere else. The projects both involved the use of a novel mass spectrometer that was developed at LLNL, so I would not have been able to do this research at any other facility. The first project that Zachary and I worked on involved using SPAMS to detect pesticides. The ability to rapidly detect pesticides in a variety of matrices is applicable to many fields including public health, homeland security, and environmental protection. Real-time, or near real-time, detection of potentially harmful or toxic chemical agents can offer significant advantages in the protection of public health from accidental or intentional releases of harmful pesticides, and can help to monitor the environmental effects of controlled releases of pesticides for pest control purposes. The use of organophosphate neurotoxins by terrorists is a possibility that has been described; this is a legitimate threat, considering the ease of access, toxicity, and relatively low cost of these substances. Single Particle Aerosol Mass Spectrometry (SPAMS) has successfully been used to identify a wide array of chemical compounds, including drugs, high explosives, biological materials, and chemical warfare agent simulants. Much of this groundbreaking work was carried out by our group at LLNL. In our work, we had the chance to show that SPAMS fulfills a demonstrated need for a method of carrying out real-time pesticide detection with minimal sample preparation. We did this by using a single particle aerosol mass spectrometer to obtain spectra of five different pesticides. Pesticide samples were chosen to represent four common classes of pesticides that are currently used in the US. Permethrin (a pyrethrin insecticide), dichlorvos and malathion (organophosphates), imidacloprid (a chloronicotinyl pesticide), and carbaryl (a carbamate) were selected for analysis. Samples were aerosolized either in water (using a plastic nebulizer) or in ethanol (using a glass nebulizer), and the particles entered the SPAMS instrument through a focusing lens stack. The particles then passed through a stage with three tracking lasers that were used to determine each particle's velocity. This velocity was used to calculate when to fire a desorption/ionization (D/I) laser in order to fragment the particle for analysis in a dual polarity time of flight mass spectrometer. Signals were digitized, and then analyzed using LLNL-developed software. We obtained chemical mass spectral signatures for each pesticide, and assigned peaks to the mass spectra based on our knowledge of the pesticides chemical structures. We then proved the robustness of our detection method by identifying the presence of pesticides in two real-world matrices: Raid{trademark} Ant Spray and a flea collar. To sample these, we simply needed to direct aerosolized particles into the SPAMS instrument. The minimal sample preparation required makes SPAMS very attractive as a detector. Essentially, we were able to show that SPAMS is a reliable and effective method for detecting pesticides at extremely low concentrations in a variety of matrices and physical states. The other project that I had the opportunity to be a part of did not involve data collection in the lab; it consisted of analyzing a large amount of data that had already been collected. We got to look at data collected over the course of about two months, when the SPAMS instrument was deployed to a public place. The machine sampled the air and collected spectra for over two months, storing all the spectra and associated data; we then looked at an approximately two-month subset of this data to search for patterns in the types of particles being detected. Essentially, we were able to identify particle types among all the spectra collected by clustering the spectra into groups of similar spectra. This was done using software that had been previously developed by our group (Dr. Paul Steele, a former group member, was instrumental in helping us learn how to use the software). Once we had found particles that seemed to recur, we faced the task of trying to figure out what these particles were. To do this, we compared the average spectra for each major cluster to those of several common compounds. We were able to tentatively identify at least one compound this way. We also looked at patterns in the appearance of different compounds. For instance, there were some compounds that only appeared at certain times of the day.

  11. Heavy ion fusion injector experiments

    International Nuclear Information System (INIS)

    We report on three experiments performed in connection with the 2 MV electrostatic quadrupole (ESQ) injector under construction at Lawrence Berkeley Laboratory. Scaled experiments have been conducted to study possible beam emittance growth due to beam aberrations in an ESQ injector. The experiment uses the SBTE (Single Beam Transport Experiment) accelerator system, quarter-scale ESQ setup and a potassium ion diode source. Measured emittance growth changes significantly with variations in current and diode energy, in good agreement with theoretical predictions. In addition, beam transport experiments were performed in a 1 MV axisymmetric electrostatic aperture column using a zeolite 1 inch diameter potassium ion source. Experimental measurements in good agreement with 2-1/2 D simulations showed that low emittance beams can be produced in axisymmetric structures. Finally, ESQ breakdown voltage tests without beam were performed at up to two times the quadrupole working voltage

    1999-01-01

    The Collisions Into Dust Experiment (COLLIDE) was completed and flew on STS-90 in April and May of 1998. After the experiment was returned to Earth, the data and experiment were analyzed. Some anomalies occurred during the flight which prevented a complete set of data from being obtained. However, the experiment did meet its criteria for scientific success and returned surprising results on the outcomes of very low energy collisions into powder. The attached publication, "Low Velocity Microgravity Impact Experiments into Simulated Regolith," describes in detail the scientific background, engineering, and scientific results of COLLIDE. Our scientific conclusions, along with a summary of the anomalies which occurred during flight, are contained in that publication. We offer it as our final report on this grant.

In the ramp withdrawal experiment, the supercritical experiment is initiated by withdrawing the transient rod from the core in a constant speed using a motor drive system. The data in the present databook consist of datasheets and graphs. Experimental conditions and typical values of measured parameters are tabulated in the datasheet. In the graph, power and temperature profiles are plotted. Those data are useful for the investigation of criticality accidents with fissile solutions, and for validation of criticality accident analysis codes. (author)

  19. Casimir experiments showing saturation effects

    International Nuclear Information System (INIS)

    We address several different Casimir experiments where theory and experiment disagree. First out is the classical Casimir force measurement between two metal half spaces; here both in the form of the torsion pendulum experiment by Lamoreaux and in the form of the Casimir pressure measurement between a gold sphere and a gold plate as performed by Decca et al.; theory predicts a large negative thermal correction, absent in the high precision experiments. The third experiment is the measurement of the Casimir force between a metal plate and a laser irradiated semiconductor membrane as performed by Chen et al.; the change in force with laser intensity is larger than predicted by theory. The fourth experiment is the measurement of the Casimir force between an atom and a wall in the form of the measurement by Obrecht et al. of the change in oscillation frequency of a 87Rb Bose-Einstein condensate trapped to a fused silica wall; the change is smaller than predicted by theory. We show that saturation effects can explain the discrepancies between theory and experiment observed in all these cases.

  20. Material Science Experiments on Mir

    Science.gov (United States)

    Kroes, Roger L.

    1999-01-01

    This paper describes the microgravity materials experiments carried out on the Shuttle/Mir program. There were six experiments, all of which investigated some aspect of diffusivity in liquid melts. The Liquid Metal Diffusion (LMD) experiment investigated the diffusivity of molten Indium samples at 185 C using a radioactive tracer, In-114m. By monitoring two different gamma ray energies (190 keV and 24 keV) emitted by the samples it was possible to measure independently the diffusion rates in the bulk and at the surface of the samples. The Queens University Experiment in Liquid Diffusion (QUELD) was the furnace facility used to process 213 samples for the five other experiments. These experiments investigated the diffusion, ripening, crystal growth, and glass formation in metal, semiconductor, and glass samples. This facility had the capability to process samples in an isothermal or gradient configuration for varying periods of time at temperatures up to 900 C. Both the LMD and the QUELD furnaces were mounted on the Microgravity Isolation Mount (MIM) which provided isolation from g-jitter. All the microgravity experiments were supported by the Space Acceleration Measurement System (SAMS); a three head three axes acceleration monitoring system which measured and recorded the acceleration environment.
