A glow discharge electron gun capable of producing a well collimated dc electron beam at energies between 1 and 6 keV and currents up to 1 A is described. The electron beam is produced in helium at pressures between 0.1 and 2 Torr without differential pumping. Beam generation efficiencies up to 80% have been measured. The electron guns are designed to pump cw ion lasers and are constructed to provide an optical path through the axis. Continuous‐wave laser oscillation in Kr II has been obtained using electron‐beam pumping of a He–Kr mixture.
