Paper Abstract

Aiming to realization of compact flash x-ray facilities, flash x-ray generator with two-stage Marx generator and a krytron pulse generator was constructed and its characteristics were verified in present study. Target and cathode of the x-ray tube was tungsten rod and graphite disk plate, respectively. Two-stage Marx generator applied high voltage to the target and discharge between electrodes produced plasma and x-ray. Experiments revealed the relationship between tube voltage, tube current and applied voltage to x-ray tube. Effect of distance from target to cathode was also made clear. Measurement of radiation output with plastic scintillator indicated the shorter pulse duration than 100 ns and the effect on application of present experimental configuration to high-speed photography. Radiographs were taken with computed radiography (CR) system. The photographs displayed enough resolution to perform fine photography and existence of soft x-ray for wide purposes. Present study implies application of present simple x-ray system to realization of compact and general-purpose x-ray generator.
