Compact soft x-ray pulse radiograph based on X-pinch and low scale fast capacitor bank

X-pinches are two or more thin wires crossed like the letter ¿X¿ in the electrode gap. As the current passes through the wires, a hot dense x-ray-emitting plasma is produced at the cross point of the wires. The high space and time resolutions achievable with X-pinch x-ray sources make them attractive for studies of short-lived low scale objects. The paper presents the results of experiments on a compact (diameter 450 mm, height 330 mm) fast capacitor bank with a current amplitude up to 300 kA and a current risetime of 200 ns. The generator load was an X-pinch consisting of four thin tungsten wires. Clear soft x-ray backlighting images of different objects in different spectral ranges were obtained. In the spectral range > 1 keV, the size of the radiation source is no more than 5 microns and in the spectral range > 10 keV, it is 10 microns. The width of the radiation pulse is 2-3.5 ns for the spectral range < 5 keV. The radiograph is compact enough to be transported to another laboratory for various experiments.
