Research Abstract |
Sensors with high time and spece resolution were challenged to be developed for for measuring propagating surface discharge. First, a micro sensor was proposed based on MEMS technology and a prototype was assembled. It turned out, however, the internal insulation strength of micro sensor was not enough for measuring discharge phenomena. Thus, the electro-optic sensor with 1ns and 3micro resolutions were developed and applied to the surface discharge measurement. From the comparison with the measured data and the numerically simulated results based on continuity equation, the critical condition for keeping propagation was clarified.. Breakdown phenomenon across micrometer-scale gap was also measured. And it turned out that the discharge process in such a small gap has a similar characteristics of discharge in vacuum.
