Repetitively pulsed electron beam generator

Repetitively pulsed electron beam generators must be developed for future high average power applications such as laser pumping and plasma heating for fusion reactors. We have begun the development of high average power technology at the parameter level required for electron beam sustained CO2 lasers, thus most of the results discussed were obtained from a system with the following nominal characteristics: average power 30 kW, beam voltage 250 kV, 50 pps, pulselength 3 microseconds, beam area 15 cm × 50 cm, current density 1 A/cm².
