Limiting Instabilities in Multibunch : Review and Cures Alban Mosnier, CEA/DAPNIA - Saclay

Limiting Instabilities in Multibunch : Review and Cures Alban Mosnier, CEA/DAPNIA - Saclay. Since very high beam currents are distributed among many tightly spaced bunches unstable coupling between bunches through long-range wakefields has become the main limiting instability
