Abstract

Electrical gas discharge can produce a powerful electron beam which in this way where the traditionally used hot cathode electron source is not necessary. In this study a concave cold cathode electron gun with a simple configuration is described for the energy up to 30 keV. Helium in a low pressure is used as working gas. The discharge condition is called obstructed discharge. A negative DC high voltage is applied to a concave cathode up to -30 kV which determines electron energy. The dependence of gas pressure to the current at target plate for given voltages up to 30 kV and voltage-pressure characteristics at different beam currents were measured.
