Experiment research on HPM pulse compression

The paper presents the results of the experiment research on HPM pulse compression at S band by the method of switched energy storage. The input pulse is of the power ranged from 1.0 2.7MW and 1.4m s width. The width of output pulse is about 13 14ns, the power gain is about 40 and the output power is 106MW. A spontaneous gas breakdown switch is used. It is shown that the rise time of output pulse is depended on the gas pressure and gas ingredient and the power gain is of no relation with the rise time of output pulse.
