AN EXPERIMENTAL INVESTIGATION OF THE TRAPPING AND ENERGY LOSS MECHANISMS OF INTENSE RELATIVISTIC ELECTRON RINGS IN HYDROGEN GAS AND PLASMA

摘要

The results of an experimental study on the trap¬ping and energy loss mechanisms of intense, relativistic electron rings confined in Astron-like magnetic field geometries are presented. The work is subdivided into four sections:gas trapping;average ring electron energetics;plasma trapping, and hollow-beam cusp-injec¬tion into gas and plasma.nThe mechanisms by which the injected beam coales¬ces into a current ring in the existing Cornell RECE-Berta facility are considered first.
