Description
technical field [0001] The invention relates to the technical field of gas discharge observation, in particular to a gas gap discharge electronic energy quantitative measurement system and a measurement method. Background technique [0002] The gap discharge process has been a long-term concern in the high-voltage field. For long-gap discharges, the related theories of streamer and leader as two important physical processes have been widely accepted, while for short-gap discharges, the streamer stage may have formed through the gap. The conductive channel completes the breakdown of the gap. [0003] Most of the existing gap discharge process observations focus on the characteristics of optical morphology, thermodynamic parameters, and charge quantity. The corresponding measurement methods include recording optical images, arraying photomultiplier tubes to obtain streamer development speed, and so on. [0004] Recording optical images is to conduct microsecond-level high-spe...
