MULTI-BEAM PULSED ACCELERATOR FOR ELECTRON BEAM PROCESSING SYSTEM

This report describes the design and experimental study of the accelerator for electron beam processing. The accelerator produces an electron beam with the energy up to 200 keV, the peak current up to 1 A, the pulse duration about 10 s and the repetition rate of 18 kHz. The electron pulses are produced by a cold pyrolitic carbon mosaic cathode with a threshold volt-ampere characteristic. The experimental experience obtained with 200 keV accelerator module gave us the base for starting the construction of a full scale, low cost accelerator with the energy of about 1 MeV and output power of about 30, 300 and 1000 kW.
