Study of the Anatomy of the X-Ray and Neutron Production Scaling Laws in the Plasma Focus

摘要

This report investigates the correlation between the neutron (and x-ray) emission intensity and the intensity of the particle beams generated in a plasma focus discharge in deuterium as an extension of our previous work on scaling laws of x-ray and neutron production. The structure of dense plasmoids which emit MeV ions has been recorded by ion imaging with pinhole camera and contact print techniques. The plasmoids are generated in the same region in which particle beams, neutron and x-ray emission reach a maximum of intensity. Sharply defined boundaries of the ion-beam source and of plasmoids have been obtained by ion track etching on plastic material CR-39.
