Abstract

A cold cathode vacuum discharge tube (50) is used in a circuit for generating pulsed auto-electronic emissions which are particularly intense and frequent in the abnormal glow discharge region. The discharge tube is characterized by a large electrode area at least of the cathode, and a large interelectrode gap. The electrodes preferably have a surface area of 16 cm<2> or more and they are preferably spaced at least 3 cm apart in a parallel relationship on each side of an excitor probe which is centered between them. In another configuration the probe forms the anode and the plates are cathodes. The circuit is driven from a direct current source of impedance sufficient to prevent establishment of a vacuum arc discharge. <IMAGE>
