Near Term Hybrid Passenger Vehicle Development Program. Phase I, Final report. Appendix B: trade-off studies. Volume I

Description: Trade-off studies of Near Term Hybrid Vehicle (NTHV) design elements were performed to identify the most promising design concept in terms of achievable petroleum savings. The activities in these studies are described. The results are presented as preliminary NTHV body design, expected fuel consumption as a function of vehicle speed, engine requirements, battery requirements, and vehicle reliability and cost. (LCL)

Defect states in plasma-deposited a-Si:H. Technical progress report, August-October 1979

Description: Raman and ESR measurements were used to study the atomic bonding and defect concentrations. Features are identified in the Raman spectra which can be attributed to configurations containing Si-Si, Si-As and As-As bonds. Features due to all three of these configurations were found to simultaneously exist, thus excluding a chemically ordered model of the bonding. However, the composition dependences of the features do not follow exactly a random bonding model either. The H bonding configurations … more

ATOMLLL: a three-D opaque molecule system (Lawrence Livermore Laboratory version)

Description: The program ATOMLLL draws color, shaded, hidden-surface pictures and movies of ball-and-stick and space-filling molecular models. From a file containing the colors and radii of the atoms, the coordinates of their centers, and the descriptions of bonds, if any, the program computes the visible portions of each atom. ATOMLLL then writes their descriptions into a file that can be copied to tape. The tape is read by a Varian minicomputer, which controls the plotting on the Dicomed D-48 color-film r… more

Operating manual for the electrostatic glove-box prefilter installed inside the filter glove box No. 046 at Rocky Flats, Building 776

Description: Objective of the evaluation is to evaluate the effectiveness of the electrostatic prefilter in prolonging the life of HEPA (high-efficiency particulate-air) filters. The theory of the electrostatic filter is reviewed, and Glove Box Number 046 is described in detail, followed by a description of the electrostatic prefilter used in the present application. Engineering drawings of the electrostatic prefilter are included. The procedure for evaluating the electrostatic prefilter includes the steps … more

Elimination of defects in plasma polymerized films used in laser fusion targets

Description: This study was conducted to understand and control the parameters governing the formation of defects in plasma polymerized surfaces. An inductively-coupled discharge was used as the source of activated monomer. Four types of well characterized surface irregularities were produced on glass slides which were subsequently fluorocarbon coated. Optimization of the process variables is discussed. (MOW)

Tantalum fabrication

Description: Two components made from LLL stock tantalum sheets have failed to operate as designed under high-explosive loading. The as-fabricated metallurgical state of the tantalum was suspected as one possible cause. To investigate this possibility, the microstructure, hardness, and chemical composition of the component material was evaluated. Both as-received tantalum starting sheets and a formed component were evaluated. The evaluation showed that these components were given an anneal that relieved str… more

Computer language evaluation for MFTF SCDS

Description: The computer languages available for the systems and application implementation on the Supervisory Control and Diagnostics System (SCDS) for the Mirror Fusion Test Facility (MFTF) were surveyed and evaluated. Four language processors, CAL (Common Assembly Language), Extended FORTRAN, CORAL 66, and Sequential Pascal (SPASCAL, a subset of Concurrent Pascal (CPASCAL)) are commercially available for the Interdata 7/32 and 8/32 computers that constitute the SCDS. Of these, the Sequential Pascal avai… more

On setting magnets in the PEP beam-transport line

Description: This paper discusses magnets in the PEP beam-transport line. Topics discussed are: conditioning, direction of excitation, rate of excitation; determination of the excitation current for the principal bend magnets; steering mechanisms; bump magnets; and determination of excitation currents of the quadrupole magnets.
