A summary of the theoretical developments of the problem of plasma arc-drop in thermionic energy converters carried out during 1976 to 1982 at Princeton University is presented. It reviews the basic formulation of the isothermal model which delineates the physical origin of the arc-drop, its order of magnitude and the possibilities of arc-drop reduction under one-dimensional, steady-state, ignited-mode operation, and also the generalization of the isothermal model to the non-isothermal model. The possibility of a heat-to-laser energy recombination laser using a thermionic diode operating in the unsteady mode is discussed. An analysis of the low-current regime with attentions focussed on the effects of ion reflections and trapped-ions effects in the emitter sheath is presented.
