Elucidation of triggering characteristics for a trigatron spark gap by measuring UV light

자외선측정(紫外線測定)에 의한 트리거트론시동특성(始動特性)의 해명(解明)

Triggering characteristics of a trigatron spark gap have been studied by measuring self-emission UV light. By combining the measurement of the UV light with that of the trigger gap voltage and the lain discharge current, we distinguished clearly the differences between the trigatron operations in which the lain discharge occurs after the trigger discharge in the case of sale polarity between the trigger pin and the lain electrode at the opposite side, and the lain gap breakdown takes place before the formation of the trigger spark in the case of different polarity. We show the observation of UV radiation with the other electromagnetic measurements is a simple and reliable scheme to investigate the triggering properties of the trigatron spark gaps.
