An electro-optical measurement on electric field of insulator surface under HV pulse in vacuum

It is well known that the modification of insulator surface electric field contributes significantly to the surface flashover in vacuum. For the purpose of studying the surface electric field, an on-line measurement system based on Kerr electro-optical effect is developed. And the preliminary experiments are performed, in which a modified surface field is observed when insulator is being stressed by a HV nanosecond square pulse.
