Initial Operating Experience and Recent Development on the TRIUMF Optically Pumped Polarized H sup Minus Ion Source.

摘要

A polarized H/sup /minus// ion source using optical pumping techniques has been developed at TRIUMF. This source was used to demonstrate (on an ion source test stand) the feasibility of producing 10 mu A of (approximately)60% polarized H/sup /minus// ion beam in a dc mode suitable for injection into the TRIUMF cyclotron. The source has been installed in a 300 kV high voltage terminal connected to the cyclotron via a recently constructed beam transport line. A polarization of 80% is anticipated near the end of 1988 after the installation of a superconducting solenoid to the source. In this paper we describe the initial operating experience, recent developments, and the future plans for the TRIUMF optically pumped polarized ion source. 9 refs., 5 figs. (ERA citation 13:047247)
