Longitudinal beam instability driven by coherent radiation in an SSMB laser modulator
Yingjie Dai, Zhuoyuan Liu, Tong Li +2
Storage ring-based steady-state microbunching (SSMB) is a promising approach for generating high-average-power coherent radiation, while the instabilities driven by coherent undula…

Instantaneous and Retarded Interactions in Coherent Radiation
Zhuoyuan Liu, Xiujie Deng, Tong Li +1
In coherent radiation of an ensemble of electrons, radiation field from electrons resonantly drives the other electrons inside to produce stimulated emission. The radiation reactio…
