ABSTRACT
In previous papers I have shown that a revision is required to the basic approach for predicting net currents in thermionic energy conversion diodes. Revised equations were developed to properly account for electron reflection and temperature coefficient effects. Electron spectrum equations for averaging transmission coefficients were also developed. In this paper the spectrum equations are simplified and several new developments are presented that relate to the revised methodology. Recent developments include a demonstration of the general applicability of the new equations, equations for space charge that include the effects of reflection and an emitting collector, and electron cooling equations with electron reflection effects included. In addition, methods are developed to apply the new equations to non-uniform surfaces. © 2000 American Institute of Physics.
