Popis: The Moscow Institute for Nuclear Research atomic‐beam type source of polarized negative hydrogen ions is described. The production of H− ions is based on the resonant charge exchange of polarized thermal hydrogen atoms and D− ions in deuterium plasma. Improvements in the D− plasma source are outlined. The polarized source produces a pulsed H− beam with a peak current up to 1 mA and a pulse duration of 180 μs at a repetition rate of 10 Hz. The normalized emittance for 90% of the beam particles is 1.8 π mm mrad. The polarimeter of low energy H− ions is also described. The polarization of the H− ions was measured to be 0.87±0.02.
