Description
A continuous-wave surface-plasma negative hydrogen ion source is used at 2 MeV tandem accelerator with vacuum insulation at the Budker Institute of nuclear physics since 2006 [1]. The source uses the hydrogen-cesium Penning discharge with plasma injection from hollow cathodes, and negative hydrogen ion production due to interaction of plasma particles with anode electrode surface [2]. It routinely produces dc H- beam in the range 1 ÷ 9 mA in daily runs with accelerated proton beam delivery to the lithium target of BNCT experimental device. Source parameters and maintenance statistics during long-term operation will be discussed. Recent upgrades, made for increasing beam current production and transport will be presented as well.
