2-mm microwave interferometer
A 2-mm microwave interferometer has been developed, and phase shift measurements have been made on the Baseball II experiment. The interferometer system employs a 140-GHz receiver for double down conversion of the plasma signal to a 60-MHz, IF frequency. The 140-GHz references signal is also down-converted and compared with the plasma signal to provide the desired phase change of the signal passing through the plasma. A feedback voltage from a 60-MHz discriminator to a voltage-controlled oscillator in the receiver provides frequency stability of the 60-MHz IF signals.

3-D nonlinear evolution of MHD instabilities
The nonlinear evolution of ideal MHD internal instabilities is investigated in straight cylindrical geometry by means of a 3-D initial-value computer code. These instabilities are characterized by pairs of velocity vortex cells rolling off each other and helically twisted down the plasma column. The cells persist until the poloidal velocity saturates at a few tenths of the Alfven velocity. The nonlinear phase is characterized by convection around these essentially fixed vortex cells. For example, the initially centrally peaked temperature profile is convected out and around to form an annulus of high temperature surrounding a small region of lower temperature. Weak, centrally localized instabilities do not alter the edge of the plasma. Strong, large-scale instabilities, resulting from a stronger longitudinal equilibrium current, drive the plasma against the wall. After three examples of instability are analyzed in detail, the numerical methods and their verification are discussed.

3-dimensional beam scanning system for particle radiation therapy
In radiation therapy treatment volumes up to several liters have to be irradiated. Today's charged particle programs use ridge filters, scattering foils, occluding rings collimators and boluses to shape the dose distribution. An alternative approach, scanning of a small diameter beam, is analyzed and tentative systems specifications are derived. Critical components are scheduled for fabrication and testing at LBL.

10-75-kWe-reactor-powered organic Rankine-cycle electric power systems (ORCEPS) study. Final technical report
This 10-75 kW(e) Reactor-ORCEPS study was concerned with the evaluation of several organic Rankine cycle energy conversion systems which utilized a /sup 235/U-ZrH reactor as a heat source. A liquid metal (NaK) loop employing a thermoelectric converter-powered EM pump was used to transfer the reactor energy to the organic working fluid. At moderate peak cycle temperatures (750/sup 0/F), power conversion unit cycle efficiencies of up to 25% and overall efficiencies of 20% can be obtained. The required operating life of seven years should be readily achievable. The CP-25 (toluene) working fluid cycle was found to provide the highest performance levels at the lowest system weights. Specific weights varies from 100 to 50 lb/kW(e) over the power level range 10 to 75 kW(e). (DLC)

236-Z canyon utilization study
The 236-Z canyon contains equipment for repurification of plutonium and recovery of plutonium from scrap material. To meet production requirements of Fast Flux Test Facility/Clinch River Breeder Reactor oxide with the existing plant, several new pieces of equipment will be needed in the future. More storage space and a better accountability system are needed to support this increased production. The available canyon space needs to be utilized to its fullest in order to accommodate the new equipment. The purpose of this document is to identify the new pieces of equipment, show how they fit into the flowsheet, and locate them in the canyon.

Acceleration of partially stripped ions at the Bevalac
Results are presented of the first attempts to accelerate partially stripped heavy ions in the Bevatron. Experiments were performed for hydrogen-like argon and neon ions, and, although the survival time of these ions in the 10/sup -7/ torr Bevatron vacuum was not sufficient to achieve full energy, valuable charge-changing cross section information was obtained.

Activities of the Physical Data Group. [Lawrence Livermore Laboratory]
A system is described in which neutron interaction data are collected from nuclear physics laboratories throughout the world, organized, evaluated, and then stored for easy access in a computer network. Computer codes that use the data to solve neutron interaction problems were also developed. The system supplies reliable up-to-date data, selects specific types of data on request, provides output in a variety of forms (reports, microfiche, microfilm), and functions rapidly and efficiently. 3 figures.

Advanced waste forms research and development. Comprehensive progress report
Progress is reported in the following research areas: cesium fixation in aluminosilicates and supercalcine development; low sodium wastes and high sodium wastes. Phase relations in the appropriate (for supercalcine) portion of the Cs/sub 2/O-Al/sub 2/O/sub 3/-SiO/sub 2/ system are being investigated. Several compatibility lines (tie lines) have been established on the phase diagram. Methods of preparing pure single phases of CsAlSiO/sub 4/ and CsAlSi/sub 2/O/sub 6/ (pollucite) are being developed. Compatibility studies continue to be the basis of supercalcine crystalline phase formation modeling. (LK)

Aerial Gamma-Ray and Magnetic Survey of the Delta Area--Utah: Final Report, Volume 1
From abstract: Results of an ERDA-sponsored, high-sensitivity, airborne gamma-ray spectrometer and magnetometer survey of a portion of the Delta, Utah, NTMS, 1:250,000 scale quadrangle, carried out under Bendix Field Engineering Corporation Subcontract 76-019-L are discussed. The objective of the survey was to evaluate the Delta area as a uraniferous province, i.e., a region showing surface indications of a generally higher uranium content, and evidence of geochemical uranium enrichment over the other natural radioactive elements, where detailed exploration for uranium would likely be successful. The known presence of late stage Tertiary rhyolites and granites associated with fluorite and uranium occurrences and one productive uranium mine strongly suggested that the area is such a uraniferous province. A DC-3 aircraft equipped with a gamma-ray spectrometer using nine large-volume NaI detectors, two 400 channel analyzers, and ancillary geophysical and electronic equipment was employed for data collection.
