ADDITIVE CONVERTER STUDIES
Abstract
A Reemitter-Mo collector converter was tested with Cs and CsF additive. The most significant effect of the CsF observed is a lowering of the collector work function by 0.1 to 0.15 volts. This collector work function reduction is evident in retarding plot measurements and in the increase of the output voltages at the 'knee' of current-voltage curves. The effect of the additive on the work function of the emitter has not been clearly formulated at this time. Under conditions of high power output the emitter work function appears effected. At lower Cs pressures, however, an increase in work function is observed for high CsF arrival rates, while low CsF arrival rates result in work functions lower than the Cs-only case. A Reemitter - Mo collector converter was operated for 150 hours with Cs and CsF additive and then subjected to metallurgical examination. The emitter, collector and seal structures were examined and no corrosion attributable to the presence of CsF was detected.
