Progress on the development of optically pumped polarized ion sources is reported. The production of polarized Li/sup -/ or Na/sup -/ ions is based on the production of Li or Na atoms by an atomic oven, polarization of the Li or Na atoms by optical pumping, ionization on a heated oxidized tungsten surface to form Li/sup +/ or Na/sup +/ ions, and converted to polarized Li/sup -/ or Na/sup -/ ions in a potassium or cesium vapor cell. The conversion of /sup 3/He/sup +/ ions into polarized /sup 3/He/sup -/ ions will be accomplished by the pickup in a low magnetic field of two electrons in two separate collisions in an optically pumped electron spin polarized Na vapor target. Polarized H/sup -/ ions are produced by using an optically pumped electron spin polarized Na vapor target in a large magnetic field to partially convert H/sup +/ ions into electron spin polarized H/sup 0/ atoms. The electron spin polarization is transferred to the proton by a Sona diabatic transition. The fast nuclear polarized H/sup 0/ atoms are then partially converted to polarized H/sup -/ ions in a second unpolarized alkali vapor target. (WHK)
