Structural safety features for superconducting magnets (open access)

Structural safety features for superconducting magnets

A survey has been carried out for various potential structural safety problems of superconducting fusion magnets. These areas include: (1) Stresses due to inhomogeneous temperature distributions in magnets where normal regions have been initiated. (2) Stress distributions and yield forces due to cracks and failed regions. (3) Superconducting magnet response due to seismic excitation. These analyses have been carried out using a variety of large capacity finite element computer codes that allow for the evaluation of stresses in elastic or elastic-plastic zones and around singularities in the magnet structure. Thus far, these analyses have been carried out on UWMAK-I type magnet systems. (auth)

A Self-Control Approach to Weight Control (open access)

A Self-Control Approach to Weight Control

A strategy for facilitating post-treatment weight maintenance was examined. Subjects were matched for age, sex, and amount of weight that they desired to lose and were then assigned to one of two groups. Both groups were under contracts and had individually designed self-control programs for weight loss, but subjects in the experimental group lost weight in small steps and subjects in the control group lost weight continuously. The experimental group was predicted to have better weight maintenance after treatment because of a greater number of reinforcements for weight loss. Two-month follow-up data was obtained on the ten subjects who completed the study, and the experimental group was found to have regained significantly less than the control group after treatment ended. The implications of these results for obesity research are discussed.

Cycling indices for ecosystem models (open access)

Cycling indices for ecosystem models

The study of ecosystems is aided by representing structural and functional groups of organisms or processes as discrete components. A complex compartment model will explicitly map pathways from one compartment to another and specify transfer rates. This quantitative description allows insight into the dynamics of flow of nutrients, toxic chemicals, radionuclides, or energy. Three new indices that calculate compartment-specific probabilities of occurrence and recycling and illustrate the problem of applying these indices to ecosystem models are presented.

Development and initial characterization of amorphous metals rich in W and/or RE (open access)

Development and initial characterization of amorphous metals rich in W and/or RE

Studies of refractory metal alloys concentrated on two families of such alloys: ternary tungsten alloys and binary T/sub 5/-T/sub 9/ alloys. The former were selected because of the possibility of finding desirable glasses consisting of low-cost components; the latter were chosen because they could be quenched into metallic glasses with high thermal stability and good toughness. Alloys selected for study were prepared by arc-melting and were subsequently rapidly quenched in an arc furnace quenching unit. Considerable difficulties were encountered in preparing metal--metalloid alloys, such as W--B, as well as alloys combining high melting and low melting transition metals, such as W and Ni. Brittleness of ductility as revealed by a bend test was noted. Measurements were made up to 1000 K and resistivity measurements up to 1300 K. The probe for electrical resistivity measurements at high temperatures has been constructed and tested. To determine the elastic (Young's) moduli of new metallic glasses prepared in this program, equipment utilizing the pulse--echo method was set up.

Determination of nitrogen in boron carbide with the Leco UO-14 Nitrogen Determinator (open access)

Determination of nitrogen in boron carbide with the Leco UO-14 Nitrogen Determinator

Use of various metals as fluxes for releasing nitrogen from boron carbide in the Leco Nitrogen Determinator was investigated. Metals such as iron, chromium, and molybdenum that wet the graphite crucible all promoted nitrogen release. Tin, copper, aluminum, and platinum did not wet the graphite and were of no value as fluxes. A procedure for sample handling and the resulting performance of the method are described. The precision at 0.06 to 0.6 percent nitrogen averaged 4 percent relative standard deviation.

Neutron capture cross sections for unstable nuclei in the mass 90 region derived from proton capture measurements. [Strength functions] (open access)

Neutron capture cross sections for unstable nuclei in the mass 90 region derived from proton capture measurements. [Strength functions]

Experimental measurements were made of the production cross sections and energy distributions of gamma rays emitted when the stable targets /sup 88/Sr, /sup 89/Y and /sup 90/Zr are exposed to protons in the energy range 3 to 8 MeV. The data are being analyzed using a recent version of the Uhl statistical model code. One conclusion is that while the gamma-ray strength functions employed reproduce the proton capture cross sections, they do not achieve the same degree of hardness observed in the measured spectra. To do so, their lower energy regions must be modified; such changes, however, do not affect the capture cross sections. 7 references.

Magnetic field measurements on ISABELLE storage ring magnets (open access)

Magnetic field measurements on ISABELLE storage ring magnets

In 1978 the magnetic field shapes of six ISABELLE prototype dipole magnets were measured in detail. All the harmonic terms that are forbidden by symmetry in dipole magnets are found to have values that are zero to within the allowed tolerances. This result indicates that the random errors in conductor placement are within tolerances and that the assembly techniques are satisfactory in this regard. However, the first allowed error term in a dipole magnet, the sextupole term, is much too large, and varies greatly from magnet to magnet resulting in field errors at the edge of the desired good field region that are 10/sup -3/ of the central field value, whereas the tolerable field errors are of the order of 10/sup -4/ of the central field value. This large sextupole term has been traced to assembly errors which yield a coil assembly which instead of being circular in cross section is racetrack shaped, with the vertical axis being 10 to 20 thousandths of an inch greater than the horizontal axis. This problem will be corrected in the future production series.

Temperature-gradient and heat flow data, Grass Valley, Nevada (open access)

Temperature-gradient and heat flow data, Grass Valley, Nevada

A series of 16 shallow and intermediate-depth temperature-gradient holes were drilled for Sunoco Energy Development Co. in Grass Valley, Pershing County, Nevada, on leases held by Aminoil USA, Inc., under the cost-sharing industry-linked program of the Department of Energy. Thirteen shallow (85-152 m) and 3 intermediate-depth (360-457 m) holes were completed and logged during the period June through September, 1979. The locations of these holes and of pre-existing temperature-gradient holes are shown on plate 1. This report constitutes a final data transmittal and disclosure of results. The drilling subcontractor was Southwest Drilling and Exploration, Inc. of Central, Utah. They provided a Gardner-Denver 15W rig, a 3-man crew, and supporting equipment. A l l holes were drilled with mud as the circulating medium. Drilling histories for each hole are summarized in table 1. GeothermEx, Inc. performed on-site geological descriptions of the cuttings; obtained several temperature profiles for each hole, including an equilibrium profile taken 23 days or more after cessation of drilling; selected samples for thermal conductivity measurements; integrated temperature, temperature-gradient, and heat-flow data obtained in this project with published values; and prepared this report.
