Abstract

The studies of a repetitive flash x-ray generator as an energy source achieved with a compact diode with a permeable anode are described. This source consisted of the following essential components: a constant negative high-voltage power supply of up to -100kV, a modified two-stage Marx pulser, a repetitive trigger device, and an x-ray tube. Two condensers in the pulser were charged from -50 to -80kV, and the output voltages (no-load) were less than -130kV. Since the capacity of each condenser was 85OpF, the total capacity during discharge was 425pF. The maximum tube voltage and the tube current were about 85kV and 0. 3kA, respectively. The xray pulse widths were less than l2Ons, and the repetitive rate was less than 40Hz. The time-integrated x-ray intensity was about 25pC/kg at 24mm per pulse with a charged voltage of 60kV and an anode-cathode (A-C) space of 9. 0mm, and the maximum size of the x-ray source was equivalent to an anode diameter of 27mm.
