The article considers the experimental and analytical study results of the energy process-
es occurring during the tests on a lossless cathode, operating at the electrons thermal
emission from a heated emitter surface. In particular, we consider thermal processes at
the electrodes occurring during testing of a lossless cathode in a diode circuit. We ana-
lyzed the terms in the power balance at the electrodes for the steady-state heat transfer
case. We investigated the mutual radiation exchange between the cathode and the anode.
We show experimentally and theoretically that the anode presence has a significant effect
on the cathode thermal balance. The cathode-compensators used in the electric propul-
sion system will increase gas economy and improve mass-dimension characteristics. In
addition, when developing the electric propulsion system, which uses new working sub-
stances, the cathode-compensator design will not need to be changed.
Keywords:
lossless cathode, cathode-compensator, heat balance, diode circuit
