ABSTRACT:
Apparatus for generating primary electrons from a cathode. The apparatus is associated with a gas discharge chamber in which forced gas discharges are maintained and consists of a body carrying concentric conductors, one of which is a cylinder and the other of which extends through and beyond the cylinder and carries at its free end a plate-type cathode which is electrically connected to the cylinder by heating filaments extending therebetween and arranged behind the cathode plate.
