Abstract: 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 is stored in high-$Q$ ${\mathrm{TE}}_{01}$ and ${\mathrm{TE}}_{02}$ 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 $7\ensuremath{\mathbin:}1--11\ensuremath{\mathbin:}1$ with efficiency in the range of 50%--63%.
