An electron gun with beam formation in the high-voltage glow discharge
Abstract
An electron gun is described for the formation in a glow discharge of beams with a cross section of about 200 sq cm, an electron energy of 120-150 keV, a current density of about 10 mA/sq cm, and a pulse duration of up to 50 microsec. The cathode part consists of a steel hollow cathode and a brass grid about 20 mm from the cathode; the anode part consists of a brass grid attached to the ring electrode. The radial density distributions of beam currents under various conditions were determined. The electron gun described here is used in an atmospheric-pressure, electric-discharge CO2 laser.
