Unresolved dielectronic satellites of the resonance line of heliumlike iron (Fe XXV)
(1s/sup 2/nl - 1s2pnl, n greater than or equal to 3) dielectronic satellites of the resonance line of Fe XXV at 1.85 A have been observed from PLT (Princeton Large Torus) tokamak discharges and are used for a detailed comparison with theory. The necessary corrections for Doppler broadening measurements are discussed, and accurate satellite to resonance line ratios allowing for a determination of the total dielectronic recombination rate of Fe XXV are derived.

Uranium Resource Assessment Through Statistical Analysis of Exploration Geochemical and Other Data. Final Report. [Codes Eval, Sure]
We have developed a procedure that can help quadrangle evaluators to systematically summarize and use hydrogeochemical and stream sediment reconnaissance (HSSR) and occurrence data. Although we have not provided an independent estimate of uranium endowment, we have devised a methodology that will provide this independent estimate when additional calibration is done by enlarging the study area. Our statistical model for evaluation (system EVAL) ranks uranium endowment for each quadrangle. Because using this model requires experience in geology, statistics, and data analysis, we have also devised a simplified model, presented in the package SURE, a System for Uranium Resource Evaluation. We have developed and tested these models for the four quadrangles in southern Colorado that comprise the study area; to investigate their generality, the models should be applied to other quandrangles. Once they are calibrated with accepted uranium endowments for several well-known quadrangles, the models can be used to give independent estimates for less-known quadrangles. The point-oriented models structure the objective comparison of the quandrangles on the bases of: (1) Anomalies (a) derived from stream sediments, (b) derived from waters (stream, well, pond, etc.), (2) Geology (a) source rocks, as defined by the evaluator, (b) host rocks, as defined by the …

User's manual for the Functional Relay Operation Monitor (FROM)
Sandia's Digital Systems Development Division 1521 has developed a new functional relay tester. Capabilities of this tester include the measurement of coil and contact resistance, hipot, operate current, and contact operation and bounce times. The heart of the tester is a Hewlett-Packard 21MX minicomputer that uses BASIC or FORTRAN programming languages. All measurements are made by means of simple program calls, and all measurement standards are traceable to the National Bureau of Standards. Functional relay test data are stored on a disc drive and can be output as hard copy, manipulated in the computer, or sent over a distributed-system link to other Sandia computers. 17 figures, 4 tables.

Volatile production during preignition coal history. Quarterly progress report, September 1980-December 1980
The goal of this program is to determine the characteristic pyrolysis behavior of representative coals under laser heating. The use of CO/sub 2/ laser enables a controllable heating rate to be given to the coal particles as they pass through the laser beam. The development of such a laser heating diagnostic should prove to be an extremely valuable tool for generation of a data base necessary for the future design of coal burning facilities. The experimental configuration is illustrated. A dilute coal/gas stream, surrounded by an inert shield flow is passed through a laser beam from an Avco HPL CO/sub 2/ laser. Under a prescribed flux density, and thus heating rate, the particles pyrolyse. The gaseous products are sampled and subsequently analyzed (primarily by gas chromatography) for carbon conversion. Particle temperature is to be monitored by a two-color pyrometer and particle velocity evolution of the pyrolysis process can be determined. The data can then be correlated with a detailed kinetic and transport model, which will enable the representative kinetic parameters to be determined.

Wave-driver options for low-aspect-ratio steady-state tokamak reactors
Low aspect ratio designs are proposed for steady-state tokamak reactors. Benefits stem from reduced major radius and lessened stresses in the toroidal field coils, resulting in possible cost savings in the tokamak construction. In addition, a low aspect ratio (A = 2.6) permits the application of a bundle divertor capable of diverting 3-T fields to a power reactor using STARFIRE technology. Such a low aspect ratio is possible with the elimination of poloidal field coils in the central hole of the tokamak, which implies a need for noninductive current drive. Several plasma waves are considered for this application, and it appears likely that a candidate can be found which reduces the electric power for current maintenance to an acceptable value.

WEDGE-AND-STRIP ANODES FOR CENTROID-FINDING POSITION-SENSITIVE PHOTOM AND PARTICLE DETECTORS
We discuss new anode geometries, employing position-dependent charge partitioning, which can be used with microchannel plates, planar proportional counters, and mesh dynode electron multipliers to obtain a two-dimensional position signal from each detected photon or particle. Only three or four anode electrodes and signal paths are required, yet images comprised of a number of detected events have little geometric distortion and the resolution is not limited by thermal noise inherent in resistive sheet anodes. We present an analysis of the geometrical image nonlinearity in the relationship between event centroid location and the charge partition ratios. Fabrication and testing of two wedge-and-strip anode systems are discussed. Images obtained with EUV radiation and microchannel plates that verify the predicted performance of this readout system are shown. We emphasize that the spatial resolution of the wedge-and-strip anode is in no way limited by the coarseness of the anode conductor pattern. The resolution is of the order of 0.4% of the image field size, and could be further improved by adopting low noise signal circuitry. Tradeoffs encountered in the design of practical x-ray, EUV, and charge particle image systems are discussed.

Western Regional Final Supplemental Environmental Impact Statement: Rulemaking for Small Power Production and Cogeneration Facilities - Exemptions for Geothermal Facilities
Section 643 of the Energy Security Act of 1980 directed the Federal Energy Regulatory Commission to develop rules to further encourage geothermal development by Small Power Production Facilities. This rule amends rules previously established in Dockets No. RM79-54 and 55 under Section 201 and 210 of the Public Utility Regulatory Policies Act of 1978 (PURPA). The analysis shows that the rules are expected to stimulate the development of up to 1,200 MW of capacity for electrical generation from geothermal facilities by 1995--1,110 MW more than predicted in the original PURPA EIS. This Final Supplemental EIS to the DEIS, issued by FERC in June 1980, forecasts likely near term development and analyzes environmental effects anticipated to occur due to development of geothermal resources in the Western United States as a result of this additional rulemaking.

[Wyoming Uranium Evaluation] Volume 1: A Summary of the Geology and Uranium Potential of Precambrian Conglomerates in Southeastern Wyoming
From deposit: Since 1975 a cooperative effort between the United States Department of Energy, United States Geological Survey, Geological Survey of Wyoming, the Geology Department, University of Wyoming, and various industry groups has resulted in the discovery of a series of uraniumthorium-and gold-bearing conglomerates in Late Archean and Early Proterozoic metasedimentary rocks of southern Wyoming. The mineral deposits were found by applying the time and strata bound model for the origin of uranium-bearing quartz-pebble conglomerates to favorable rock types within a geologic terrane known from prior regional mapping.

X-ray diodes for laser fusion plasma diagnostics
Photodiodes with x-ray sensitive photocathodes are commonly used as broadband x-ray detectors in fusion plasma diagnostics. We have measured the risetime of the detector system and have measured the quantum efficiency between 1 to 500 A of numerous photocathode materials of practical interest. The materials studied include aluminum, copper, nickel, gold, three forms of carbon, chromium, and cesium iodide. The results of the measurements are compared with Henke's semiempirical model of photoyield. We have studied the effects of long-term cathode aging and use as a plasma diagnostic on cathode quantum efficiency. In addition, we have measured the x-ray mass-absorption coefficient of several ultrasoft x-ray windows in energy regions where data were unavailable. Windows studied were made of aluminum, Formvar, polypropylene, and Kimfoil. Measurements between 1 to 50 A were performed with the Los Alamos Scientific Laboratory's low-energy x-ray calibration facility, and the measurements between 50 to 550 A were performed at the National Bureau of Standard's synchrotron ultraviolet radiation facility.
