Paper Abstract

The cause of pre-breakdown currents appearing between metal electrodes copper soldered with ceramics after bakeout in vacuum up to 200...440 degree(s)C was established. Quest for it was conducted from the viewpoint of a hypothesis suggested by an author earlier on vacuum insulation violation. `Triple point'--metal-insulator contact in vacuum--is referred to as a pore in the gas medium of which ionization process resulting in various kinds of vacuum insulation violation develop. Experimental results confirm the hypothesis suggested.
