The ion current from the ionizing surface (porous emitter) is investigated as a function of the surface temperature with constant cesium vapor discharge. The design of the device used in the experiment is described, and the distribution of the emitter thermocouple and the curves of ion current as a function of various temperatures are plotted. At certain temperatures a complete surface ionization was observed during cesium vapor diffusion through porous tungsten. The saturation temperature is higher with smooth emitters; at a current density of 10 mu a/cm/sup 2/, the temperature shift is approximately - 80 deg C; and at 0.25 mu a/cm/sup 2/ it is approximately -50 deg C.
