【 摘 要 】

Results obtained in several experiments on active RF pulse compression at X-band using a magnicon as the high-power RF source are presented. In these experiments, microwave energy was stored in high-Q TE01 and TE02 modes of two parallel-fed resonators, and then discharged using switches activated with rapidly fired plasma discharge tubes. Designs and high-power tests of several versions of the compressor are described. In these experiments, coherent pulse superposition was demonstrated at a 5???9 MW level of incident power. The compressed pulses observed had powers of 50???70 MW and durations of 40???70 ns. Peak power gains were measured to be in the range of 7:1???11:1 with efficiency in the range of 50???63%.
