Paper Abstract

High-current ribbon e-beam vacuum diode was designed to operate with RADAN 303 compact pulsed power source for various laboratory research purposes and technological experiments. Maximum e-energy, 200 keV; peak e-beam current, 1.8 kA; beam cross section, 5 X 110 mm2; current pulse width, 4 ns; beam energy per pulse, 1.5 J; the average beam power (in air) is 40 W at reprate of 25 pps. The parameters are given for the 40 micrometers aluminum- beryllium foil window. The diode operates under a vacuum of 10-2 to 10-3 Torr. The metal-dielectric cathode and the foil life time exceeds more than 106 pulses. The pulsed power source permits one to control the diode voltage and change electron's energy. The possibility of varying the cathode length and anode-cathode gap of the vacuum diode is also presented. Weight together with RADAN 303 is 31 kg.
