Production of H- ions by an RF driven multicusp source

  • 1. Lawrence Berkeley Laboratory, University of California, Berkeley, CA 94720 (United States)

Description

An RF driven H- source has been developed at LBL for use in the Superconducting Super Collider (SSC). To date, an H- current of ∼40 mA can be obtained from a 5.6-cm-diameter aperture with the source operated at a pressure of about 12 mTorr and 50 kW of RF power. Attempts have been made to enhance the H- beam current by introducing a small quantity of cesium vapor into the source chamber. It is found that the H- output current can be increased by a factor larger than three if some cesium is applied in the collar around the exit aperture
