Abstract
An upgrade has been completed and commissioned to the Los Alamos Proton Storage Ring (PSR) to allow direct injection of the H/sup -/ beam into the ring and to move the circulating beam off the stripper foil using an orbit bump system. The design benefits of the upgrade are matching the transverse phase space of the injected beam to the PSR acceptance and a factor-of-ten reduction of the foil hits by the circulating beam. Foil thickness is optimized to minimize the sum of circulating-beam losses and losses caused by excited H/sup 0/ states produced at injection. Design simulations predicted an overall reduction in losses by a factor of five. We discuss results of the commissioning and PSR performance in comparison to design projections and the goals of the upgrade project.Keywords
