Title: Polarized H/sup -/ source development at BNL

Conference ·
OSTI ID:5626948

The AGS polarized H/sup -/ source (PONI-1) now produces currents of 25-40 ..mu..A, and has operated reliably during polarized physics runs. A new polarized source, having as its goal mA's of H-vector, is now under development. An atomic hydrogen beam has been cooled to about 20 K with a forward flux of approx.10/sup 19/ atoms/s/sr. A superconducting solenoid having a calculated acceptance angle of 0.1 sr for the cold H/sup 0/ beam, is now being built. An ionizer for the resulting polarized H/sup 0/ beam based on resonant charge exchange of H/sup 0/ with D/sup -/, is being tested. 500 ..mu..A of H/sup -/ have been produced by ionizing an unpolarized H/sup 0/ beam using this ionizer.
