摘要：
A continuous-wave surface-plasma negative hydrogen ion source has been used at 2 MeV tandem accelerator with vacuum insulation at the Budker Institute of Nuclear Physics since 2006. The source uses the hydrogen-cesium Penning discharge with plasma injection from hollow cathodes, and negative hydrogen ion production due to the interaction of plasma particles with the anode electrode surface. It routinely produces dc II- beam in the range 1 divided by 9 inA in daily runs with accelerated proton beam delivery to the lithium target of our experimental device. Source parameters and maintenance statistics during long-term operation are discussed. Recent upgrades to increase the beam current production and transport are presented as well.
