Abstract

The acceleration of polarized protons in multi-GeV machines is a great challenge for accelerator physicists. An essential part of such development is the primary source of polarized H/sup -/ ions. Recent studies at TRIUMF and INR, Moscow, showed that pulsed Optically Pumped Polarized Ion Source (OPPIS) could produce up to 1.2 mA H/sup -/ ion beam with polarization in excess of 80% within 1.5 /spl pi/ mm-mrad normalized emittance. This current is ten times higher than the best currently available from atomic beam sources. The pulsed OPPIS is quite inexpensive in comparison with atomic beam source, and is ideally suited for high energy accelerator applications. >
