For H- charge exchange (stripping) injection to European Spallation Source (ESS) storage ring it is necessary to have H- ion source with a current of ~90 mA, pulses duration 3 ms, and repetition of 14 Hz (duty factor ~4%) extendable to repetition up

It is assumed that persistent cesiation in the SNS RF SPS is related to deposition of carbon film on the collar converter. The work function dependence for graphite with alkali deposition has no minimum typical for metals and semiconductors and the f
