Scintillation response of lithium fluoride
Thesis. Lithium fluoride crystals, with TlF added to the charge, were prepared by the Bridgman- Stockbarger method. The scintillation response to photon energies between 25 and 1250 keV for these crystals and a commercially prepared LiF (Ti) crystal was studied. The response of the LiF (Ti) crystal was compared to the response of an NE109 scintillator at 1250 keV. The dose response of the LiF (Ti) crystal was evaluated over the energy range 25 to 1250 keV. The absorption and emission spectra of the LiF (Ti) crystal are discussed. A historical review precedes the discussion. (auth)

Search for massive long lived particles in aluminum targets irradiated by 300 GeV and 400 GeV protons
A directional gas Cherenkov counter, which employed six phototubes to sample Cherenkov light from single particles having a gamma greater than ~10 was used to achieve accidental rates of less than one per day if operated near targets with surface radiation levels of as high as 10/sup +3/ r/hr. The cosmic ray background measured by the apparatus was reduced to less than one per day by mounting our directional Cherenkov counter above the irradiated targets and facing toward the earth. Two searches of a few days duration, after bombardments at energies of 300 and 400 GeV with >10/sup 16/ protons at NAL, were made in four inch thick targets of aluminum, mounted just down stream from another aluminum target. No long-lived particles were observed with cross sections for production and capture of approximately less than a micro-micro barn in a lifetime range of a few to a few thousand hours.

200-GeV ISA with room temperature magnets
A conceptual design study of 200-GeV proton intersecting storage accclerators with room temperature magnets is presented. The key to this study was thc desire to keep the electric power consumptiom to an acceptable level (40 MW). The design has been optimized by choosing small-gap (4 cm) aluminum coil dipoles operating at about 15 kG. The luminosity of this machine is limited to about 10/sup 32/ cm-/sup -2/ sec/sup -1/ by transverse space-charg e effects. An order of magnitude higher luminositics can be obtained by adding a booster of modest cost. A novel vacuum system using distributed Ti-sublimation pumps results in considerable savings. A cost comparison with a high-luminosity superconducting machine is given. (auth)

Composition of corrosion films on lithium hydride surfaces after exposure to air
An ion microprobe mass analyzer was used to investigate the reaction pathway for the formation of lithium hydroxide and lithium oxide on freshly cleaved lithium deuteride surfaces. Mass spectra were obtained from the lithium deuteride surfaces before and after exposure to room air, and the composition of the corrosion film was determined by depth-profiling methods. The corrosion film appears to be layered in the following manner: lithium hydroxide on lithium oxide on lithium deuteride. (auth)

Influence of pressure variations on the focus of electron beams used for welding
An experimental study has shown that the variations in pressure typically experienced in an electron-beam welding chamber can significantly affect the focus of the electron beam, resulting in detectable variations in weld penetration and width. (auth)
