Ionisierung eines atomstrahls mit hilfe von ladungsaustauschreaktionen zur erzeugung polarisierter protonen und deuteronen

Abstract

Charge-exchange reactions were used in an atomic-beam polarized ion source instead of electron impact ionization for production of protons and deuterons. The reactions H + + D→H + D + and D + + H → D + H + were tested. 0.27 μA deuterons and 0.17 μA protons were produced mass-separated from the atomic beam. Behind the charge-exchange volume approximately 0.4 μA deuterons or 0.25 μA protons are available in the test source. The efficiency of ionization by charge exchange is about 4 × 10 −4 and can be increased.
