ABSTRACT:
A cold cathode vacuum discharge tube is used in a circuit for generating pulsed autoelectronic emissions which are particularly intense and frequent in the abnormal glow discharge region, and involve much lower current densities than predicted by the Fowler-Nordheim vacuum arc discharge region law. The discharge tube is characterized by a large electrode area at least of the cathode, and a large interelectrode gap. The electrodes are preferably spaced at least 2 cm apart in a parallel relationship. A probe may be introduced between the electrodes to reduce still further the field required to generate the emissions. In another configuration the probe forms the anode and two plates form cathodes. The circuit is driven from a direct current source of having an impedance sufficient to prevent establishment of a vacuum arc discharge.
