Popis:	Components are being developed which will eventually be part of a high‐current polarized H− source. An atomic beam has been cooled to 6 K, resulting in a most probable velocity of approximately 680 m/s and a forward flux of about 3×1020 H0/sr/s. Focusing of this beam with a superconducting solenoid was unsuccessful at high H0 densities due to H0‐H0 scattering. A permanent magnet sextupole is now being tested. An ionizer based on the charge exchange of the polarized H0 with ≊150‐eV D− has also been studied.
