Investigation of the Influence of the Cathode Type on the Deionization Properties of a Powerful Pulse Discharge in Mercury Vapor

The concentration of charged particles and the electronic temperature of discharge plasma obtained in an ignitron were determined by means of central probes. The research was conducted on the basis of different types of cathodes: liquid or film. The measurement results obtained in this work show that a film cathode is characterized by a higher rate of vapor formation due to the passage of current pulses than does the liquid cathode.
