Abstract

A compact single focus X-rays flash device is described in this paper. This device is composed of the following essential components: a 50 kV high voltage power supply, a capacitor bank, a pulse forming line, a high frequency and high voltage switch, a voltage multiplier and an X-ray tube. Before breakdown into the X-ray tube, voltage can be rise up to 400 kV, leading to photon of maximum energy around 400 keV. The duration of voltage pulses is 100 ns. The device can work in two different modes: pulsed mode up to 700 Hz; or in the burst mode at very high frequency. The number of shots in a burst can be chosen between 2 and 6. In burst mode, the system can work up to 20 kHz.
