Shadowing in Inelastic Scattering of Muons on Carbon, Calcium and Lead at Low XBj

Nuclear shadowing is observed in the per-nucleon cross-sections of positive muons on carbon, calcium and lead as compared to deuterium. The data were taken by Fermilab experiment E665 using inelastically scattered muons of mean incident momentum 470 GeV/c. Cross-section ratios are presented in the kinematic region 0.0001 < XBj <0.56 and 0.1 < Q**2 < 80 GeVc. The data are consistent with no significant nu or Q**2 dependence at fixed XBj. As XBj decreases, the size of the shadowing effect, as well as its A dependence, are found to approach the corresponding measurements in photoproduction.Comment: 22 pages, incl. 6 figures, to be published in Z.

Capabilities of the Los Alamos National Laboratory in nuclear target technology

Targets are made at Los Alamos for experiments at the Ion Beam Facility (Van de Graaff), the Medium Energy Physics Facility (LAMPF), and for experiments conducted at many other accelerators in the US and Europe. Thin, isotopic targets are made by sputtering and evaporation. Versatile, large-scale facilities exist for ceramics and plastics fabrication, electroplating, powder metallurgy, fabrication by pressing, casting and rolling, chemical and physical vapor deposition and sputtering. Special developments include ultra-precision machining, cryogenic targets and shaped-foil targets. 20 references

Hydriding of titanium cones for a sputter-ion source

A technique for producing negative ions of hydrogen, deuterium, tritium from a sputter-ion source by sputtering hydrided titanium in the source. The hydridation of the titanium is described. (GHT

Fifth annual conference of the International Nuclear Target Development Society

A separate abstract was prepared for sixteen papers presented at the conference. Abstracts of three papers presented orally at the conference are included in the proceedings. Three papers have been abstracted previously for the data base. For abstracts of these see CONF-761055 in the Report Number Index. (RCK
