A source of polarized negative hydrogen ions with deuterium plasma ionizer

An atomic beam–type source of polarized negative hydrogen ions with deuterium plasma ionizer has been developed. A charge‐exchange reaction between thermal polarized hydrogen atoms and negative deuterium ions is used for production of polarized hydrogen negative ions. A polarized beam with peak current up to 150 μA and pulse duration 100 μs has been obtained from the source at repetition rate 5 Hz. The results of experimental test of the source developed and polarized beam emittance measurement are presented.
