Abstract:The Los Alamos Neutron Science Center (LANSCE) has upgraded the Proton Storage Ring (PSR) for the Short Pulse Spallation Source (SPSS) [1]. 100 microamperes of average beam current is now delivered to the new target assembly. One major task of the improvement project was the design and construction of a power amplifier to increase the drive voltage to the cathode follower final power amplifier used to overcome longitudinal space charge forces in the accumulated beam. With this amplifier and power supply improv… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
