A method of determining the electron reflection coefficient from the emitter surface in a thermionic-emission converter
A method is proposed for determining the transparency of the potential barrier at the surface of the emitter in a thermionic-emission converter by means of measured arc voltage-current characteristics. That method can also be used to determine the barrier transparency for the collector by measuring the voltage-current characteristics when the current flows from the collector to the emitter. The method can be used to track the variation in the reflection coefficient from the plasma for the emission electrons.
