Abstract.
A small chamber Plasma Focus that operates at 0.2 Hz for several minutes is used as a
source of hard x rays and fast neutrons. The device is powered by a microprocessor
controlled capacitor charging power supply. The x rays are used for introspective
imaging of metallic pieces, static and in motion, that allows for the detection of internal
defects as small as 1 mm. The x ray radiation is able to produce clear images of objects
placed behind several millimeters of iron and steel. The fast neutrons allow for the
detection of hydrogenated substances and can discriminate between different
concentrations of water located near the device.
