Development of a Multicusp H exp - Ion Source for Accelerator Applications

摘要

The development of a multicusp surface-production H exp - ion source (Berkeley concept) designed specifically for accelerator use is described. The goal of this development effort has been to provide a suitable H exp - ion source for the Proton Storage Ring now being constructed at LAMPF. The ion source that has been developed is now capable of long-term operation at 20 mA of H exp - current at 10% duty factor and with normalized beam emittance of 0.13 cm-mrad (95% beam fraction). The development program will be described with particular emphasis on beam emittance measurements. (ERA citation 09:006474)
