Abstract : A focused, Q-spoiled laser was used to induce electrical breakdown of the solid dielectric between two charged electrodes. The effect of the following parameters on the breakdown delay was studied: laser focal point, applied voltage (30-85 KV), charging polarity, laser power (20-90 MW), dielectric thickness (10-20 mils), and dielectric type. Delay times as short as 3 nsec, with 1 nsec jitter, were recorded. Graded dielectrics were found to decrease switch closure time through the formation of multiple breakdown channels. Observed results seem consistent with the avalanche-streamer theory of solid breakdown. (Author)
