论文摘要
电场下的加热金属丝和碱金属GASE电子的低压通过热发射发射与丝的压力和丝状的压力的关系。为了在一个计划开发大区域碱金属光子座的程序中探索这一过程，我们已经在泰勒和兰穆尔（Taylor and Langmuir）的学术中设计和建造了一个规格。我们提出了原则上的测量，这些测量值是谷葡萄蒸气中钨丝的热发射。我们描述了纠正第一幅缺陷的第二代设计。
Heated metal filaments under electric fields and low pressures of alkali metal gaseject electrons by thermionic emission as a function of the pressure of the gas and thetemperature of the filament. To explore this process in a program to develop large-area alkali metal photocathodes, we have designed and built a gauge following thestudies of Taylor and Langmuir. We present proof-of-principle measurements ofthe thermionic emission of a tungsten filament in cesium vapor. We describe a secondgeneration design that corrects flaws in the first gauge.
