Abstract : The present report is an update on activities for the second year of funding. Research leading to a detailed characterization of antiproton annihilation in nuclei has resulted in a published analysis of fast deuteron production from carbon and uranium targets. This follows previously reported work and publications by our group on gamma-ray, neutral and charged pion, proton, and neutron production. The deuteron measurements are important to our SHIVA Star antiproton- catalyzed microfission experiment at the Phillips Laboratory, Kirtland AFB, in that they help constrain theoretical models of light nuclei production and subsequent energy deposition in the target. Work continues at SHIVA Star on working fluid formation and target compression for the microfission experiment. Excellent progress has been made, both theoretically and experimentally, on these important aspects of the experiment. The Penn State group, working in collaboration with Los Alamos National Laboratory physicists, trapped and held up to 721,000 antiprotons per beam injection pulse from the LEAR accelerator during July, 1993. This was a crucial step to the ultimate goal of transferring large numbers of antiprotons to the Phillips Laboratory for the antiproton-catalyzed microfission experiment. (AN)
