An important scaling parameter or figure of merit in inertially-confined fusion is the maximum fuel rho R achieved by the target--rho is the density, and R the radius of the fuel. Every technique used, thus far, in laser-initiated-fusion-microexplosion experiments to obtain this data had major deficiencies. We examine critically the merits of the various possible methods of measuring fuel rho R and their ranges of applicability.

Time-dependent deformation and time-dependent strength are being characterized for several candidate polymeric composites for flywheels. This presentation highlights the motivation and the philosophy of the characterization adopted by the authors in establishing the ongoing programs at LLL. This overview is intended to provide a basis for inferring the type of enginering data being generated for different aspects of flywheel design. The details of these data can be obtained from the published reports and articles. Two aspects of flywheel design data are addressed: those dealing with time-dependent statistical strength, and those dealing with deformation and strength under time-varying history.

The past, present, and future thrusts of the magnetic mirror fusion program at LLL are reviewed. Neutral beam injection, stabilization, and density-lifetime product results from the 2XIIB experiment are briefly highlighted. The rationale of the Tandem Mirror Experiment and Field Reversed Mirror Experiment now under way are discussed. Plans for the Mirror Fusion Test Facility (MFTF) are described. Approaches to improvement of particle containment in mirror fusion systems are briefly indicated. (RME)

The basic purpose of the Geothermal Environmental Overview Project is to summarize and assess the state of environmental issues of the top priority KGRAs from among the 37 KGRAs currently identified by the Division of Geothermal Energy as having possibility for commercial development. The objectives of the Overview Project are inventory of available data, assessment of available data, identification of data gaps, and identification of key issues. (JGB)

The purpose of this programming project is to assign automatically reasonable molecular formulas to experimental masses obtained from high-resolution mass spectra. The program developed reads experimental carbon-12 masses, converts them to corresponding Kendrick masses, and assigns a set of reasonable molecular formulas to each Kendrick mass within a given tolerance. The computational methods to do this are based on the tables previously developed by Guffey and Weber. The methods used to search these tables and generate the corresponding molecular formulas are discussed. This program is organized now so that it is resident on a disk pack on the IBM 370/158. Data entry may be from cards or from ket-to-disk data entry (TSO) terminal. This program is being used to process data acquired from the CEC 21-110B mass spectrometer. The development of this program will be continued to increase its analytical capabilities and to increase its ease of use. Acquisition of high-resolution mass spectral data for 12 fractions obtained from separation of a Canadian Tar Oil Sand sample has been continued.
