Influence of Discharge Circuits on the Characteristics of the X-ray Flash Produced by Trigger Initiating Discharge in Vacuum

Abstract

A pulsed discharge in vacuum accompanies with a X-ray flash. The author has made a trigger initiating discharge vacuum tube, and is now under experiments with it, to produce a single and high energy X-ray flash. In operating the tube, two circuits are needed. They are a main circuit and a triggering circuit. Energy of a X-ray flash is limited by the circuit condition of the main circuit. In step of experiments, the triggering circuit become important. Because the triggering circuit affects to not only the switching time, but also waveform of the X-ray flash. The experimental results are as follows. (1) Uprising of the anode voltage brings a decreasing the rise time and increasing the crest value of the X-ray flash. (2) A smaller capacitance in the triggering circuit leads out a X-ray flash with a shorter rise time. From these results, some discussion was described on a capability of waveform operation of the X-ray flash by controlling the triggering capacitance.
