Abstract

The development of the spacecraft power unit for the spacecraft engines is associated with creation of the high – temperature radiation resistant systems of the system of current converters such as grid – controlled rectifiers and high voltage plasma thermionic diodes. The system of current converter is required to match the electrical parameters of the thermionic conversion power reactor (with output voltage of 120–150 V) to the parameters of the electric engine with operating voltage of hundreds – thousands of volts. 

In this connection the computations of the ignition voltage of the back arc – discharge in the interelectrode gap of the high voltage plasma thermionic diode are relevant and essential. In this paper, a semi empirical relation is obtained for computation of the ignition voltage of the back arc – discharge, depending on the vapor pressure of cesium in the interelectrode gap and the anode temperature. The obtained results can be implemented for the future development of devices of thermionic plasma power industry.

Keywordsinterelectrode gap, high voltage plasma thermionic diode, electric field strength, ignition voltage of the back arc – discharge, vapor pressure
