Experimental study and development of a single-focus-burst x-ray flash

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 is rise up to 400 kV. Leading to photon energy at a maximum of 400 keV. The duration of voltage pulses is 100 ns. The device could work in two different modes, in the continuous pulsed mode up to 500 Hz and in burst mode, each burst is composed by 3 to 5 shots. At this time the burst mode is running at 3.5 kHz frequency.
