Stability Enhancement of a Self-Amplified Spontaneous Emission Free-electron Laser with Bunching Containment
Huaiqian Yi, Xiaofan Wang, Li Zeng +2
The self-amplified spontaneous emission (SASE) mechanism, the fundamental operating principle of numerous free-electron laser (FEL) facilities, is driven by electron beam shot nois…
