摘要：
It is shown that it is possible to controllably and continuously elevate the electron temperature in the plasmatron thermionic energy converter from the emitter temperature to the maintenance electron temperature for the diode arc mode. Measurement of the vacuum space charge arising from the emission from a surface in cesium vapor indicates the presence of a substantial negative ion emission current. Apparatus has been constructed for identifying and directly measuring the flux of positive, negative and neutral species emitted from an electrode surface in a cesium vapor diode, in order to determine the influence of negative ion emission on the effective work function of thermionic converter electrodes. Initial data indicate the presence of H** minus , Cs** minus and possibly C** minus and CH** minus .
