Production and Dynamics of High Intensity Electron Beams

High intensity electron beam experiments are in progress at electron energies varying from 100 keV to 2 MeV. The low energy machines are Marx generators, while the high energy one is an electron beam transformer accelerator , home made with some original technical solutions. Its electron energy is 2 MeV, current > 10 kA, pulse length 20 ns at a repetition rate of 10 pps. The purpose is injection in the ANEL - type electron ring accelerators, beam dynamics and plasma - beam interaction investigations. Several models of field emission di odes have been investigated by various diagnostic methods and beam pictures on various materials have been taken.
