Title:
CHANNEL SPARK SOURCE FOR GENERATING A STABLE, FOCUSSED ELECTRON BEAM
Document Type and Number:
WIPO Patent Application WO2003071577
Kind Code:
A3
Abstract:
The invention relates to a channel spark source, triggered by gas discharge, for generating stable, focussed electron beams. Said source is characterised by a gas supply with a pressure differential of 10<-4> Pascal between the hollow cathode and the channel outlet, so that the multiplication of the charge carriers in the trigger plasma ignites a hollow cathode gas discharge in a reliable manner and that the beam exits the system without a predisposition for instability or for touching and damaging the internal channel of the system.
