Irradiation of a Spherical Target by a Single Relativistic Electron Beam

Abstract

An experimental study of irradiation of spherical targets by single relativistic electron beams has been conducted to determine deposition symmetry. A 700-keV, 300-kA, 100-nsec beam was used with diagnostics consisting of x-ray pinhole photography, flash radiography, and evaluation of anode-backing-plate damage. The degree of symmetry was typically much better than 2:1 over the target surface, indicating that single-beam irradiation could be an acceptable approach to pellet fusion.
