AbstractAbstract
[en] Polarized protons have been accelerated in the AGS to 22/yield/ GeV. The polarized source presently used produces 30-40 μA of /rvec char/H- at 75-80% polarization, in 500 μs pulses, 0.5 Hz. This is three orders of magnitude lower in intensity than normal H- operation, and higher intensities are desired. There is a program in the AGS department to develop a higher intensity source. This is a ground state atomic beam source with an atomic beam cooled to 6 K, spin selection and focusing via a superconducting solenoid (shown) or a sextupole system, and an ionizer for /rvec char/H- production based on the charge exchange of /rvec char/H/degree/ with D-. Work is in progress on all three components, and will be described in this paper. 6 refs., 7 figs
