Paper Abstract

In this work a compact electron beam source, a preionized controlled open-ended hollow cathode discharge, is used for the ablation of an anodic target. Time-resolved spectroscopic measurements of the optical emission of the filamentary and plume plasmas, both created by the electron beam, are presented and electron beam parameters are given. These latter are compared to preliminary measurements in a channel-spark.
