A method of gas admission for initiating a discharge in anode material vapors

摘要

Abstract-A method for initiating a non-self-sustained vacuum discharge in anode material vapors by admitting a gas between the discharge electrodes to a pressure p≥3×10{sup}(-2) Pa is described. This technique allows for decreasing the voltage of the anode power source from 1 kV to 200 V. Experimental characteristics of the discharge in a mixture of Ti vapors with N{sub}2 are presented, and the boundaries of the change from a gas discharge to a discharge in metal vapors are established.
