A model of hard X-rays emission from free expanding Plasma-Focus discharges

Abstract

A planar-piston model of the hard x-ray production in Plasma-Focus devices is presented. The model applies Von Karman approximations to represent the inner structure of the pinch. The hard x-ray emission is calculated assuming Bremsstrahlung from the collision on the anode base of an electron current running away from the pinch.. The model was applied to analyse the experimental data of a small Plasma Focus without surrounding cathode, finding good agreement.
