The Spallation Neutron Source H(-) ion source is operated with a pulsed 2-MHz RF (50-60 kW) to produce the 1-ms long, ∼50 mA H(-) beams at 60 Hz. A continuous low power (∼300 W) 13.56-MHz RF plasma, which is initially ignited with a H2 pressure b

In experiments with RF saddle antenna surface plasma sources (SPS), the efficiency of H− ion generation was increased by up to a factor of 5 by plasma electrode “activation”, without supplying additional Cs, by heating the collar to high temper
