The choke-mode accelerating structure is one of the higher-order-mode (HOM) damping structures. It has the advantage of relatively simple fabrication and low surface magnetic field. The high-gradient performance of X-band choke-mode accelerating structures has been studied with six different single-cell prototypes. It was observed that high electric field and small choke dimension caused...
The Accelerator Laboratory of Tsinghua University has been carrying out research on radio frequency (RF) pulse compressors at both S-band and X-band. The S-band high-power test facility mainly consists of two S-band klystrons and a SLED-I type pulse compressor. Pulse modulations including the phase-to-amplitude modulation and high efficiency pulse compression have been demonstrated...
This report includes two sections. Section I focuses on RF breakdowns of Compact Pulsed Hadron Source（CPHS）RFQ. The conditioning history curve of CPHS RFQ has been recorded. After the post-processing of experiment data，the normalized curve of the conditioning history turned into a relatively smooth curve, which indicated that the empirical formula proposed by CERN for the high gradient...
