Abstract

A small pulsed power generator is used to drive a capillary discharge in a 5mm diameter alumnina tube. A hollow cathode geometry is used and a metallic vapor formed by a laser focussed onto a target within the hollow cathode volume. The ensuing discharge is studied using a set of X-ray diagnostics, and a submillimeter diameter pinch is seen to form on axis. Spectroscopic observations show the plasma is predominantty of the cathode material. The dynamics of the plasma are studied under different preionization schemes, and the rate of rise of the main current is found to be important. Transient Hollow Cathode effects are found assist the formation of a well formed and small diameter pinch. [ABSTRACT FROM AUTHOR]
