Abstract—

An experimental study has been done of the bias effect of the active (high-voltage) electrode potential on the breakdown characteristics in a discharge tube 15 mm in diameter, filled with neon, argon, or their mixture (3 : 1) at a pressure of ~1 Torr. The bias of the potential is carried out by parallel connection to the electrode with an additional constant voltage or additional pulses with an amplitude less than the voltage for maintaining self-sustained discharge. In this case, a change in the breakdown voltage, the velocity of the pre-breakdown ionization wave, and the brightness of radiation from its front is observed. In particular, the breakdown voltage can increase up to 1.5–2 times, and this state of the discharge gap can be maintained for tens of minutes. The observed effects are assumed to be caused by the appearance of a charge on the tube wall and a change in its potential near the electrode, which affect the characteristics of the primary breakdown between the electrode and the wall and, in turn, the processes of discharge ignition. The mechanisms of appearance of the surface charge on the wall when feeding a bias voltage to electrode are investigated.

高压电极电位偏置对放电管中电离波引起击穿的影响

摘要-

已经进行了实验研究，研究了活性（高压）电极电势对直径为15 mm的放电管在高压下充满氖气，氩气或其混合物（3：1）的击穿特性的影响。 〜1托。电势的偏置是通过使用一个附加的恒定电压或振幅小于用于维持自持放电的电压的附加脉冲与电极并联连接来执行的。在这种情况下，观察到击穿电压，击穿前电离波的速度以及来自其正面的辐射亮度的变化。特别地，击穿电压可以增加到1.5到2倍，并且放电间隙的这种状态可以保持数十分钟。假定观察到的效应是由于管壁上出现电荷以及电极附近的电势变化引起的，这会影响电极与壁之间的初次击穿特性，进而影响电极的放电过程。放电点火。研究了向电极馈入偏压时壁上表面电荷出现的机理。
