摘要: Experiments are conducted to investigate the DC electrical breakdown voltage in cesium vapor between two planner molybdenum electrodes, 1.6 cm diameter, separated by a 0.5 mm gap, and relate results potential on cathode side of Alkali Metal Thermal-to-Electric Converters (AMTECs). In first set experiments, which electrodes kept at 560 650 K, while varying pressure from 0.71 29 Pa, when cooler electrode is positively biased, occurs ∼500 V, but 700 V negatively biased. second held 625 1100 K varied 1.7 235 <4 excess 400 Since ionization rate constant lower higher, respectively, than for sodium (5.14 ...
