Title: Final Report - Long life radio frequency surface plasma source

Abstract

The design of the advanced SPS with SA RF discharge was developed including optimized H- emitter, cesiation, beam extraction, formation, and transport. A prototype of the CW SA RF SPS has been developed and tested for validation of the feasibility to produce the necessary parameters. Relative to previous RF sources, the specific efficiency of positive ion generation was improved to 200 mA/cm 2 kW(a factor of 40) and the specific efficiency of negative ion generation was improved to 20 mA/cm 2 kW (a factor of 8). An advanced version of the SA SPS H-source with an improved discharge cell developed in Phase I was developed for high intensities with the goal of having high availability and improved beam parameters: average H- beam current of 15 mA, 103 hours lifetime, integrated beam lifetime 10 A-hours.
