Electron Bunch Train Excited Higher-Order Modes in a Superconducting RF Cavity
Yongfeng Gao, Senlin Huang, Fang Wang +7
Higher-order mode (HOM) based intra-cavity beam diagnostics has been proved effectively and conveniently in superconducting radio-frequency (SRF) accelerators. Our recent research…
Design study of a beta=0.09 high current superconducting half wave resonator
Hu-Tan-Xiang Zhong, Feng Zhu, Pei-Liang Fan +2
There's presently a growing demand for high current proton and deuteron linear accelerators based on superconducting technology to better support various fields of science. A \b{et…
Self-Seeded FEL Wavelength Extension with High-Gain Harmonic Generation
Ling Zeng, Weilun Qin, Gang Zhao +5
We study a self-seeded high-gain harmonic generation (HGHG) free-electron laser (FEL) scheme to extend the wavelength of a soft X-ray FEL. This scheme uses a regular self-seeding m…
Mechanical analysis of a 162.5MHz taper HWR cavity
Peiliang Fan, Feng Zhu, Hutianxiang Zhong +2
One superconducting taper-type half-wave resonator (HWR) with frequency of 162.5MHz, \b{eta} of 0.09 has been developed at Peking University, which is used to accelerate high curre…
Drive laser system for the DC-SRF photoinjector at Peking University
Zhiwen Wang, Senlin Huang, Lin Lin +4
Photoinjectors are widely used for linear accelerators as electron sources to generate high-brightness electron beam. Drive laser, which determines the timing structure and quality…
The low level radio frequency control system for DC-SRF photo-injector at Peking University
Fang Wang, Liwen Feng, Lin Lin +4
A low level radio frequency (LLRF) control system is designed and constructed at Peking University, which is for the DC-SRF photo injector operating at 2K. Besides with continuous…
Beam breakup simulation study for high energy ERL
Si Chen, Miho Shimada, Norio Nakamura +3
The maximum beam current can be accelerated in an Energy Recovery Linac (ERL) can be severely limited by the transverse multi-pass beam breakup instability (BBU), especially in fut…
The discharge characteristics of the DUHOCAMIS with a high magnetic bottle-shaped field
Dongpo Fu, Weijiang Zhao, Peng Guo +7
For the purpose to produce high intensity, multiply charged metal ion beams, the DUHOCAMIS (dual hollow cathode ion source for metal ions) was derived from the hot cathode Penning…
Study on the multi-pass, multi-bunch beam breakup for 9-cell TESLA cavities in ERL
Si Chen, Sen-Lin Huang, Yong-Ming Li +5
Generally, Energy Recovery Linac (ERL) needs special designed high current superconducting RF cavities. In this paper, the threshold current of BBU for compact ERL facilities with…
