Paper Abstract

Capillary discharge plasmas were generated with current pulses up to 200 kA and 10 - 90% rise time of about 10 ns using a water dielectric Blumlein generator. Time resolve spectra and pinhole images of the plasma columns generated in ceramic capillaries are presented. The data indicates that the plasma obtain in ceramic capillaries are hotter than those generated in polyacetal capillaries. The maximum degree of ionization, plasma dimensions and time evolution are in general agreement with model computations and show the generation of plasma columns 250 - 300 micrometers diameter with temperatures is congruent to 250 eV.
