Abstract
A magnetically insulated light ion diode which has produced an ion beam with total current exceeding 400 kA for 25 ns and generated a proton current density approaching 500 kA/cm2 is described. This intense beam current is achieved in a noncurrent neutralized mode via geometric focusing and a balance between self-magnetic field and space-charge forces. A number of techniques are described which have been used to diagnose the beam production, transport, and focusing. These include observation of Kα emission due to beam-induced atomic excitation, prompt-γ radiation due to beam-induced nuclear reactions, and thermal emission due to beam-target heating.This publication has 18 references indexed in Scilit:
