  • Abstract
    A report is presented on the first five months of operation of the Optically Pumped Polarized Ion Source (OPPlS) for the nuclear physics research program at Los Alamos Meson Physics Facility (LAMPF). The LAMPF OPPIS is unique in using Ti:Sapphire lasers to polarize the potassium charge-exchange medium, and until recently was unique in using a superconducting magnet in the electron cyclotron resonance (ECR) source and polarizer regions. The ECR extraction electrode biasing arrangement is also unique. Typical performance was 25 mu A of peak current (measured at 750 keV) with 55% beam polarization or 15 mu A at 62%. Ion source availability was greater than 90%. Also reported on are planned improvements in preparation for research operation in May of 1991.<>
