Experimental Investigations of the Cesium Plasma Cell

Abstract
Some aspects of the performance of a cesium plasma cell with tantalum emitter are evaluated in terms of experimental determinations of the effects of variations in such parameters as cesium vapor pressure, emitter temperature, and emitter‐collector separation distance. Experiments relating to the effect of collector serrations and to the feasibility of radiation shielding are described. Voltage‐current characteristics are presented for several emitter temperatures and for a wide range of cesium vapor pressure.
