Vacuum, 1956
An rf ion source of conventional type is shown to yield a current of 2.2 μa of negative hydrogen ions. This is accomplished by charge exchange of the positive ions emerging from the plasma with the neutral gas in the probe channel. The negative ion beam is well focused, and the performance of the source is 0.22 μa/cc at NTP/hour.

An advanced negative hydrogen ion source
Review of Scientific Instruments, 2015The results of investigation of emission productivity of negative particles source with cesiated combined discharge are presented. A cylindrical beam of negative hydrogen ions with density about 2 A/cm2 in low noise mode on source emission aperture is obtained.
