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.
