Self-consistent calculations of the expansion of a plasma source of the hollow cathode type into an ambient plasma are presented. The source is polarized with respect to the surrounding medium. The model considered is a fluid model with inclusion of anomalous friction arising from plasma instabilities. The potential profiles which are calculated show a very large extent of the interaction region.

Abstract
Self-consistent calculations of the expansion of a plasma source of the hollow cathode type into an ambient plasma are presented. The source is polarized with respect to the surrounding medium. The model considered is a fluid model with inclusion of anomalous friction arising from plasma instabilities. The potential profiles which are calculated show a very large extent of the interaction region. Correspondingly quite substantial current enhancements with respect to the operation of the plasma source in vacuum are obtained.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
