/ Zhang, L.H. (Beijing, Inst. High Energy Phys. ; Beijing, GUCAS ; CAS, IHEP, Dongguan) ; Tang, J.Y. (Beijing, Inst. High Energy Phys. ; Beijing, GUCAS ; CAS, IHEP, Dongguan)
A large collider project CEPC-SPPC is under study with a global effort and a leading role from IHEP, with CEPC (Circular Electron-Positron Collider, Phase I) to probe Higgs physics and SPPC (Super Proton-Proton Collider, Phase II) to explore new physics beyond the Standard Model. The key design goal for SPPC is to reach 75 TeV in center-of-mass energy with a circumference of 100 km. [...]

Implementation of RF modulation in Booster for mitigation of the collective effects in the transient process after the swap-out injection
/ Xu, H (Beijing, Inst. High Energy Phys.) ; Duan, Z (Beijing, Inst. High Energy Phys.) ; Wang, N (Beijing, Inst. High Energy Phys.) ; Xu, G (Beijing, Inst. High Energy Phys.)
On-axis swap-out injection is a promising injection scheme for the diraction-limited storage rings with small dynamic apertures. However, some previous studies have shown that the initial mismatch in the longitudinal phase space may lead to transverse collective instability before approaching the equilibrium state, especially in the high bunch charge situation. [...]

Studies and mitigation of TMCI in FCC-ee
/ Migliorati, Mauro (Rome U. ; INFN, Rome) ; Zannini, Carlo (CERN) ; Antuono, Chiara (CERN) ; Gibellieri, Dora (Rome U. ; CERN) ; Zobov, Mikhail (Frascati) ; Behtouei, Mostafa (Frascati) ; Soos, Roxana (IJCLab, Orsay ; CERN) ; Zhang, Yuan (Beijing, Inst. High Energy Phys.)
Previous studies have identified turbulent mode coupling instability (TMCI) as one of the most severe single-bunch instabilities in the FCC-ee collider, potentially limiting its performance. Its threshold is influenced by both transverse and longitudinal wakefields arising from vacuum chamber resistive wall effects, discontinuities, and beam-beam interactions, the latter of which can be seen as a transverse cross-wake force.In this paper, we investigate the TMCI using the most recent collider parameters and an updated impedance model.

Combined Effect of Beam-Beam Interaction and Beam Coupling Impedance in Future Circular Colliders
/ Zhang, Yuan (Beijing, Inst. High Energy Phys. ; Beijing, GUCAS) ; Carideo, Emanuela (CERN ; Rome U. ; INFN, Rome) ; Migliorati, Mauro (Rome U. ; INFN, Rome) ; Wang, Na (Beijing, Inst. High Energy Phys.) ; Zobov, Mikhail (Frascati)
The future large scale electron-positron colliders, such as FCC-ee in Europe and CEPC in China, will rely on the crab waist collision scheme with a large Piwinski angle. Differently from the past generation colliders both luminosity and beam-beam tune shifts depend on the bunch length in such a collision scheme. [...]
