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…

Particle swarm optimization fitting of long-range wake potentials for trapped-mode parameter characterization in the HALF storage ring
Haiyan Yao, Tianlong He, Xiaoyu Liu +2
Accurate extraction of trapped-mode impedance parameters of complex storage ring components is essential for assessing their impact on coupled-bunch instabilities. This paper propo…
