Transverse coupled-bunch instabilities driven by high-order modes near the coupling resonance
You Sun, Weiwei Li, Tianlong He +3
Betatron coupling near the difference resonance has been explored and adopted in several fourth-generation storage rings, yet its influence on high-order-mode-driven transverse cou…

Convexity of the longitudinal variation of third-order resonance driving terms and its application in dynamic aperture optimization
Wanbin Li, Zihan Wang, Yuejing Huang +2
The optimization of the dynamic aperture (DA) of a storage ring is typically a non-convex problem with multiple local optima. Recent studies showed that reducing the variation of r…

Impact of short-range wakefields from radio-frequency cavity resonant modes on bunch lengthening
Tianlong He, Jincheng Xiao, Weiwei Li +2
The high-performance operation of fourth-generation synchrotron light sources critically depends on harmonic cavities (HCs) to alleviate statistical collective effects through bunc…
