| Abstract | An RF pulse compression system based on double-height waveguides was studied for the Klystron-based CLIC main linac. The optimized power gain of the new system is 3.78, with a specific output pulse shape required for the transient beamloading compensation. A method based on the waveform parameters of the input pulse was introduced to achieve such an output pulse shape. This pulse compression system consists of a storage cavity of a Barrel Open Cavity (BOC) type and four correction cavities. The BOC storage cavity has a Q0 of 2.35 × 105 with the TM32,1,1 mode and a β of 6.6. A novel RF coupler was designed to facilitate the machining procedure of the BOC storage cavity. For the correction cavities, a bowl cavity with the TE1,2,4 mode and a spherical cavity with the TE1,1,3 mode were selected for the potential correction chain. Three prototypes were designed, fabricated, and RF measured validating the fabrication procedure for the series production. |
