Abstract

Tacitrons are triode gas-discharge tubes, similar in construction to thyratrons. The primary functional difference between a tacitron and a thyratron is that the tacitron is designed to be completely grid-controlled, whereas a thyratron has grid control only over ignition. Demountable cesium-barium (Cs-Ba) tacitrons have exhibited very low forward voltage drops in the range of a few volts, hold-off voltages greater than 200 V, and average conduction current densities greater than 10 A/cm/sup 2/. These characteristics yield an average power switching density in the order of 10/sup 3/ W/cm/sup 2/ approaching 95% peak switching efficiency. This parameter regime places the Cs-Ba tacitron in the range of conventional solid-state devices, with the advantage that the tacitron should reliably operate in extremes of temperature and radiation. The high-current tacitron has been designed to modulate average currents in the range of 100 to 200 A, with the intent of demonstrating continuous power conditioning capability in the kilowatt range.

大电流可拆卸铯钡电子管的工作特性

瞬变电子管是三极管气体放电管，结构类似于闸流管。静控管和闸流管的主要功能区别在于静控管被设计为完全栅格控制，而闸流管只有在点火时才有栅格控制。可拆卸铯钡(Cs-Ba)静电加速器的正向电压降非常低，只有几伏，保持电压大于200 V，平均传导电流密度大于10 a /cm/sup /。这些特性产生的平均功率开关密度为10/sup 3/ W/cm/sup 2/，接近95%的峰值开关效率。该参数体系使Cs-Ba铯原子介电子处于传统固态器件的范围内，其优点是铯原子介电子可以在极端温度和辐射下可靠地工作。大电流静电加速器被设计为在100到200 A的范围内调制平均电流，目的是展示在千瓦范围内的连续功率调节能力。
