Ultrafast X-ray introspective imaging of metallic objects using a Plasma Focus

A compact-chamber 4.7 kJ, 30 kV, Plasma Focus operated in deuterium was use d as a ultrafast high intensity radiation source for introspective radiogra phic imaging of metallic objects. The samples to be imaged were located out side the Plasma Focus chamber, about 1 m away from the chamber wall. A high -sensitivity, fast-response commercial radiographic film was used as a X-ra y detector. Experimentally obtained images are presented showing a very hig h penetration power of the X-ray beam, demonstrating that the presented com pact-chamber Plasma Focus is suited for introspective visualisation of piec es manufactured on metal.
