Description
At the Los Alamos Neutron Science Center (LANSCE), the LANSCE Accelerator Modernization Project (LAMP) aims to replace the aging front-end, including the H- ion source. The new H- source, based on the RF ion source at SNS, uses a low work function surface for H- ion production, necessary for achieving higher H- current densities. This paper describes simulations and results from a proof-of-concept experiment involving photoemission-based measurements on metallic surfaces—a potential diagnostic for measuring the work function of the LAMP H- ion source.
