Abstract
We designed and fabricated an S-band compact pulse compressor with a single spherical resonant cavity and an RF polarizer for the S-band high power test facility at Tsinghua University. The average power gain of the pulse compressor was optimized to 5.2 with input pulse length of 3.6 μs and a compression ratio of 12. This pulse compressor will replace the existing SLED-type pulse compressor with two cylinder resonant cavities, which makes the RF system of the high-power test facility compact. The RF design, mechanical design and cold test of the pulse compressor are presented in this paper.
