Abstract


Results verification of recovery method of vacuum diode volt-ampere characteristics (VAC), based on a single high voltage pulse and current response, are presented. Experimental verification was done vacuum diode with single crystal LaB6 (100), and there was a good correspondence between the received VAC of a vacuum diode and the theoretical one. Under using a thermionic cathode of pressed composition material Ba0,25Sr0,75HfO3 abnormal Schottky effect was recorded and a possible distortion of VAC received by traditional methods is shown. Experimental verification of the method confirms its applicability also for thermionic cathode characteristic determination under fact processes.

Keywords
