Compact Source of Electron Beam with Energy of 200 KeV and Average Power of 2 kW

The paper describes a compact electron beam source ELVI-200/2 with average electron energy of 200 keV. The source operates with pulse power up to 2 MW under average power not higher than 2 kW, pulse duration 0.2÷2 mks, and repetition rate up to 5 kHz. The electron beam is extracted through aluminium – beryllium alloy foil. The pulse duration and repetition rate can be changed from control desk. High-voltage generator for the source with output voltage up to 220 kV is realized using the voltage-doubling circuit which consists of 30 sections. The insulation type – gas, SF 6 under pressure of 8 atm. The cooling of the foil supporting tubes is provided by a water – alcohol mixture from an independent source.
