OPTICAL DIAGNOSIS OF HIGH POWER MICROWAVE AIR BREAKDOWN
A diagnostic method of HPM breakdown in waveguide is presented. Experiment results, such as optics-electronics signal of air breakdown, the decline constant of HPM discharge plasma and verification of the conjecture that breakdown point shifts to source. In the mean time, experiment of short pulse HPM breakdown in free space is done. We take the systematic picture of HPM breakdown in free space. Therefore, the directly knowledge of breakdown characteristic is obtained.
