Effect of irradiation on the tensile properties of niobium-base alloys (open access)

Effect of irradiation on the tensile properties of niobium-base alloys

The alloys Nb-1Zr and PWC-11 (Nb-1Zr-0.1C) were selected as prime candidate alloys for the SP-100 reactor. Since the mechanical properties of niobium alloys irradiated to end-of-life exposure levels of about 2 x 10SW neutrons/mS (E > 0.1 MeV) at temperatures above 1300 K were not available, an irradiation experiment (B-350) in EBR-II was conducted. Irradiation creep, impact properties, bending fatigue, and tensile properties were investigated; however, only tensile properties will be reported in this paper. The tensile properties were studied since they easily reveal the common irradiation phenomena of hardening and embrittlement. Most attention was directed to testing at the irradiation temperature. Further testing was conducted at lower temperatures in order to scope the behavior of the alloys in cooldown conditions.

Solar oscillations, gravitational multipole field of the sun and the solar neutrino paradox (open access)

Solar oscillations, gravitational multipole field of the sun and the solar neutrino paradox

The visual solar oblateness work and the solar seismological work on the internal rotation of the sun are reviewed and their implications concerning the static gravitational multipole moments of the sun are discussed. The results of this work are quite deviant which is indicative of the complexity encountered and of the necessity for continued studies based on a diverse set of observing techniques. The evidence for phase-locked internal gravity modes of the sun is reviewed and the implications for the solar neutrino paradox are discussed. The rather unique possibility for testing the relevance which the phase-locked gravity modes have to this paradox is also noted. The oscillating perturbations in the sun's gravitational field produced by the classified internal gravity modes and the phase-locked modes are inferred from the observed temperature eigenfunctions. Strains of the order of 10/sup -18/ in gravitational radiation detectors based on free masses are inferred for frequencies near 100 ..mu..Hz. The relevance of these findings is discussed in terms of a new technique for use in solar seismological studies and of producing background signals in studies of low-frequency gravitational radiation. 64 refs., 2 figs.

Solution to workshop problem 6 (hollow sphere) in the shell approximation with EDDYNET-2D (open access)

Solution to workshop problem 6 (hollow sphere) in the shell approximation with EDDYNET-2D

The problem of the hollow sphere in a sinusoidal field has been solved in the single shell approximation with the code EDDYNET. Solutions with three different meshes are compared among themselves and with axisymmetric solutions obtained by 2-D codes. Agreement is good for total current and for field at points outside the sphere. Agreement is fair for field at interior points, where the field results from near cancellation of applied and induced fields. Agreement is poor for power dissipation and for the field at points in or near the conducting shell. The limited agreement is to be expected in using a single shell to model a hollow sphere with thickness greater than one skin depth.

Mini-proceedings of the workshop on heavy ion physics and instrumentation for a 15-Tm booster and storage ring

The goal of this workshop was to probe in depth a few of the areas of possible physics made possible by the availability of an intermediate energy heavy-ion physics facility. There was a special emphasis on physics that would be possible only with a storage/cooler ring. Topics discussed were nuclei far from stability, quantum electrodynamics, giant resonances and photonuclear reactions, and high energy gamma-ray production. Individual papers in this meeting were abstracted separately.

Internal targets in storage rings (open access)

Internal targets in storage rings

While fixed-target experiments in storage rings were suggested more than twenty-five years ago, little work has been done and virtually none in this country although interest seems to be growing. We survey the advantages, limitations and possibilities. Luminosities of L approx. = 10/sup 33/cm/sup -2/s/sup -1/ for electrons up to 15 GeV should be achievable now with the PEP storage ring at SLAC with good beam lifetime and emittance for target thicknesses n/sub t/ approx. 10/sup 15//cm/sup 2/. This is thin but ideal for optically pumped, polarized gas targets. Providing longitudinally polarized beams at such targets would provide a unique facility for high luminosity polarized e/sub +-/ + polarized ..gamma.., polarized e/sub +-/ + polarized A and polarized ..gamma.. + polarized A experiments. Other possibilities include the production of both external and internal beams for basic and applied science. Multiple bypass insertions are considered for thicker targets as well as production and storage of exotic, short-lived beams or for production of photon beams with undulators. The related question of multi-turn injection and extraction is also considered in such a context. Several systematic machine physics studies are suggested, e.g., ion-induced, multi-bunch instabilities with e/sub +-/ beams. The SLAC storage ring PEP …

Design considerations for a combined synchrotron-light source and heavy-ion storage ring Atomic Physics Facility (open access)

Design considerations for a combined synchrotron-light source and heavy-ion storage ring Atomic Physics Facility

An Atomic Physics Facility (APF) based on the combination of photons produced by a synchrotron light source with heavy ions in a storage ring will open the way to the study of ionic states of almost all elements. The design considerations for such a facility are discussed in terms of the use of synchrotron radiation for photoexcitation and ionization experiments. Design considerations for an APF are given in terms of the accelerator facilities presently available at BNL which include the National Synchrotron Light Source and Tandem Van de Graaff Laboratory. The results show that the concept is valid and therefore that implementation would result in entirely new capabilities for the study of multiply-ionized atoms.

Spectroscopy of light and heavy quarks

New results on various controversial light mesons are reviewed, including the glueball candidates f/sub 2/(1720) and eta(1460), the 1/sup + +/-0/sup - +/ mass ''coincidences'' f/sub 1/(1285)-eta(1275) and f/sub 1/(1420)-eta(1420), as well as evidence for the X(3100)..--> lambda..anti p+n..pi.. and the rho(1480)..-->..phi ..pi.., which have quantum numbers not allowed for q anti q. The ..gamma gamma -->..VV effects move out of the threshold region with data on ..gamma gamma --> omega..rho. Statistically weak data on GAMMA/sub ..gamma gamma../eta/sub c/ and the search for heavy quark P/sub 1/ states are presented. GAMMA/sub ee/, B/sub ..mu mu../, and GAMMA/sub tot/ for the UPSILON(1S), UPSILON(2S), and UPSILON(3S) are updated using new data and a consistent treatment of the radiative corrections for GAMMA/sub ee/. New data on the mass splittings of the chi/sub b/(2P) compare favorably with the scalar confinement model, which may however have new trouble. 150 refs., 43 figs.

Incorporation of the KERN ECDS-PC software into a project oriented software environment (open access)

Incorporation of the KERN ECDS-PC software into a project oriented software environment

The Stanford Linear Accelerator Center (SLAC) is in the process of building a new particle collider, the Stanford Linear Collider (SLC). The tunnel which houses the SLC is about 3 km long and contains approximately 1000 magnets. Besides a very precise absolute positioning of these magnets, the alignment of adjacent magnet ends is of particular importance to the success of the whole project. Because of this and the limited time frame, a survey method which was not only reliable and self-checking but also fast had to be developed. Therefore, the concept of MAS (Magnet Alignment System) was developed. This system utilizes the on-line data collection and the rigorous least-squares bundle adjustment of the KERN ECDS-PC system to fulfill these requirements. The ECDS software is embedded in a project tailored software system with modules which take care of: fixture and magnet calibration corrections, the calculation of ideal coordinates and their comparison to measured coordinates, the translation of detected misalignments into the coordinate system of the mechanical adjustments and the control of the adjustments with on-line electronic dial-gauges. This paper gives a brief introduction to the SLC project and some of the survey problems which are unique to this machine. The basic …

Production and shielding of x rays from electron beam vapor sources (open access)

Production and shielding of x rays from electron beam vapor sources

Electron-beam vapor sources are now widely used in material processing sciences and coating technologies, such as the semiconductor industry for producing aluminum films on Si wafers; the metallurgical industry for melting, evaporating, and refining metals; and at Lawrence Livermore National Laboratory (LLNL) for vaporizing metals for laser isotope separation applications. Power for these sources ranges from the kW regime in the semiconductor industry to the multi-MW regime in laser separation technology. Operations of these sources can generate copious amounts of x rays by the direct and indirect interactions of the energetic electrons with the target materials. In this paper, we present the results of our calculations regarding the x-ray emission intensity, angular intensity and energy spectrum distribution, and shielding characteristics for vapor sources with acceleration voltages from 10 kV to 60 kV. 4 refs., 12 figs., 2 tabs.

Personal dosimetry in a mixed field of high energy muons and neutrons (open access)

Personal dosimetry in a mixed field of high energy muons and neutrons

High energy accelerators quite often emit muons. These particles behave in matter as would heavy electrons and are thus difficult to attenuate with shielding in many situations. Hence, these muons can be a source of radiation exposure to personnel and suitable methods of measuring the absorbed dose received to these people is obviously required. In practical situations, such muon radiation fields are often mixed with neutrons, well-known to be an even more troublesome particle species with respect to dosimetry. In this paper, we report on fluence measurements made in such a mixed radiation field and a comparison of dosimeter responses. We conclude that commercial self-reading dosimeters and film badges provided an adequate measure of the absorbed dose due to muons.

Induction linacs for heavy ion fusion

Experimental progress to date has strengthened our belief in the soundness and attractiveness of the heavy ion method for fusion. What surprises that have shown up in the laboratory (e.g., in SBTE) have all been of the pleasant kind so far. The systems assessment has supported the view that the heavy ion approach can lead to economically attractive electric power and that a wide variety of options exists in all parameters. The systems work has also been of great help in pointing the way for the research and development activities.

Bounds on Galactic Cold Dark Matter Particle Candidates and Solar Axions From a Ge-Spectrometer

The ultralow background Ge spectrometer developed by the USC/PNL group is used as a detector of cold dark matter candidates from the halo of our galaxy and of solar axions (and other light bosons), yielding interesting bounds. Some of them are: heavy standard Dirac neutrinos with mass 20 GeV less than or equal to m less than or equal to 1 TeV are excluded as main components of the halo of our galaxy; Dine-Fischler-Srednicki axion models with F/2x/sub e/' less than or equal to 0.5 x 10/sup 7/ GeV are excluded. 22 refs., 7 figs.

Climatic indicators for estimating residential heating and cooling loads

An extensive data base of residential energy use generated with the DOE-2.1A simulation code provides an opportunity for correlating building loads predicted by an hourly simulation model to commonly used climatic parameters such as heating and cooling degree-days, and to newer parameters such as insolation-days and latent enthalpy-days. The identification of reliable climatic parameters for estimating cooling loads and the incremental loads for individual building components, such as changing ceiling and wall R-values, infiltration rates or window areas is emphasized.

Storage rings, internal targets and PEP

Storage rings with internal targets are described, using PEP as an example. The difference between electrons and heavier particles such as protons, antiprotons, and heavy ions is also discussed because it raises possibilities of bypass insertions for more exotic experiments. PEP is compared to other rings in various contexts to verify the assertion that it is an ideal ring for many fundamental and practical applications that can be carried on simultaneously. (LEW)

Potential polymer concrete heat exchanger tubes for corrosive environments (open access)

Potential polymer concrete heat exchanger tubes for corrosive environments

It has long been known that carbon steel exposed to some geothermal brines is aggressively attacked, and large corrosion allowances must be made in the design of piping used in such environments. In addition, scaling of the pipes reduces the flow through within a short period of time. Several high temperature polymer concretes have been developed which can be used as non-corrosive liner materials. In addition, polymer concretes with high thermal conductivities have been developed which may be used as heat exchanger tubes for geothermal brines. Studies have indicated that polymer concretes will not scale as rapidly as carbon steel does, thus making them attractive alternatives for heat exchanger tubes. Thin walled, thermally conductive polymer concrete tubes have been made that can withstand pressures >4.1 MPa at 150/sup 0/C without leaking. Continuing studies are being made to characterize these materials and evaluate them for heat exchanger applications.

X-ray safety at the Los Alamos National Laboratory (open access)

X-ray safety at the Los Alamos National Laboratory

An organized and structured safety program for x-ray generating devices was initiated in October, 1979. An X-ray Device Control Office was established to manage the program that currently oversees the activities of 201 x-ray generating devices and to provide SOP reviews, perform shielding calculations, and provide training for both the operators and health physics x-ray device surveyors. The new program also establishes controls for procurement of new equipment, requires the writing of Standard Operating Procedures, requires training for operators and provides routine and non-routine safety inspections of x-ray generating devices. Prior to this program going into effect, the Laboratory had recorded nine documented x-ray related exposure accidents. Since then, there have been none. Program elements and experiences of interest to other x-ray device users are discussed. 3 refs.

The effect of fabrication variables on the irradiation performance of uranium silicide dispersion fuel plates (open access)

The effect of fabrication variables on the irradiation performance of uranium silicide dispersion fuel plates

The effect of fabrication variables on the irradiation behavior of uranium silicide-aluminum dispersion fuel plates is examined. The presence of minor amounts of metallic uranium-silicon was found to have no detrimental effect, so that extensive annealing to remove this phase appears unnecessary. Uniform fuel dispersant loading, low temperature during plate rolling, and cold-worked metallurgical condition of the fuel plates all result in a higher burnup threshold for breakaway swelling in highly-loaded U/sub 3/Si fueled plates.
