摘要

研究了用紫外照射气体和电极的触发火花隙的性能。制作了一个测试电路,可以调节紫外线的强度和相对定时。测量了这对触发火花间隙所需电压的影响。结果表明,紫外的存在降低了启动火花间隙闭合所需的触发电压。在紫外线的存在下,触发电压的脉冲间变化也减小了。实验还表明,触发脉冲与紫外照射之间的相对时间对火花隙的触发有显著的影响。最后,开发了一种驱动电路,该电路在触发脉冲时自动计时火花隙的紫外线照射,并在触发脉冲的持续时间内维持紫外线的产生。结果显示了这些设计修改的结果所带来的改善。

Characterisation of a triggered mid-plane spark gap with UV illumination
The performance of a triggered spark-gap has been investigated in which the gas and electrodes are illuminated with UV. A test circuit was produced in which the intensity and relative timing of the UV could be adjusted. The effect that this had on the voltage required to trigger the spark-gap was measured. It was demonstrated that the presence of UV reduces the required trigger voltage to initiate the closure of the spark-gap. The pulse to pulse variation of this trigger voltage is also decreased in the presence of UV. It was also shown that the relative timing between the application of the trigger pulse and the UV illumination has a marked effect on the triggering of the spark-gap. Lastly a drive circuit has been developed which selftimes the UV illumination of the spark-gap when the trigger pulse is applied and sustains the generation of UV for the duration of the trigger pulse. Results are presented demonstrating the improvement seen as a result of these design modifications.
