Abstract

Abstract

A design of an optical pumping source with multichannel surface discharge is introduced. The effects of the trigger voltage and risetime, and the thickness of dielectric substrate on trigger characteristic are analyzed theoretically. The electric field at two electrodes of each channel is intensely deformed, and it is nearly zero at the middle of channels by the action of trigger voltage. Two methods including taking pictures of discharging channels with high-speed multi-frame camera and measuring discharge current with Rogowski coils have been used experimentally to study the discharge synchronism and uniformity of the pumping source. The jitter of about 20 ns of 10 channel uniform discharge is obtained on the conditions of the charging voltage -20 kV, the trigger voltage of 30 kV with th
