Development of a quadripartite wakefield structure as dechirper for free electron laser
Yu Ji, Congrui Lei, Jiahang Shao +13
Wakefield structures are critical for beam manipulation in free-electron lasers (FELs), particularly when serving as dechirpers, where beam-induced longitudinal wakefields compensa…
Demonstration of Direct-amplification Enabled Harmonic Generation in an Ultraviolet Free-Electron Laser
Hao Sun, Jitao Sun, Li Zeng +14
We report the experimental demonstration of direct-amplification enabled harmonic generation in an ultraviolet free-electron laser (FEL) driven by a low-intensity seed laser. By em…
Mains-Synchronized Timing Trigger for Stability Enhancement in FEL Pulsed Microwave Systems
Jinfu Zhu, Hongli Ding, Haokui Li +3
Pulsed microwave stability in linear accelerators (LINACs) is critical for maintaining high-quality electron beams in synchrotron radiation and free-electron laser (FEL) facilities…
Prototype design of a digital Low-Level RF system for S3FEL S-band Transverse Deflecting Cavities
Jinfu Zhu, Hongli Ding, Haokui Li +7
Transverse Deflecting Cavities (TDCs) are generally adopted for electron beam diagnosis. Three sets of S-band and two sets of X-band TDCs are planned at Shenzhen Superconducting So…
