Polarized H- source development at BNL
- 1. Brookhaven National Lab., Upton, NY
Description
The AGS polarized H- source (PONI-1) now produces currents of 25-40 μA, and has operated reliably during polarized physic runs. A new polarized source, having as its goal mA's of H, is now under development. An atomic hydrogen beam has been cooled to about 20 K with a forward flux of λ1019 atoms/s/sr. A superconducting solenoid having a calculated acceptance angle of 0.1 sr for the cold H0 beam, is now being built. An ionizer for the resulting polarized H0 beam based on resonant charge exchange of H0 with D-, is being tested. 500 +A of H- have been produced by ionizing an unpolarized H0 beam using this ionizer
