Description
This paper presents the design of a compact X-band two-stage pulse compression system featuring bowl-shaped open cavities, developed for a newly acquired 6-MW X-band klystron. The system consists of a correction cavity chain, a first-stage and a second-stage storage cavity. By employing bowl-shaped geometries, which have an unloaded quality factor ($Q_0$) higher than those of spherical cavities, the system significantly enhances both power gain and compression efficiency. With an input pulse of 5-µs from the klystron, the first-stage pulse can be flattened, generating a two-stage compressed pulse of 200 ns with exponentially decaying waveforms, thereby achieving a total peak power gain of ≥10.
