OPPIS DEVELOPMENT AT TRIUMF

Optical pumping has proven to be a very efficient technique for the pr oduction of polarized beams and polarized targets. Polarization transf er collisions between protons, atomic hydrogen or deuterium, and optic ally pumped alkali-metal vapor atoms are successfully implemented in t he high current optically pumped polarized ion sources (OPPIS) and the laser-driven sources (LDS) for target applications. The feasibility o f a 20 mA polarized H- ion current has been demonstrated. Pulsed OPPIS applications for the future RHIC and HERA polarized beam facilities a re discussed. Nuclear polarized Li-8 beams produced by optical pumping , for P-NMR surface studies with a new ISAC facility at TRIUMF, are al so considered.
