Description
Intrabeam scattering (IBS) in the SwissFEL injector has emerged as a critical performance-limiting phenomenon, manifesting as a significantly larger slice energy spread than previously anticipated. By combining detailed numerical simulations with a newly developed analytical model, we achieve excellent agreement with experimentally measured slice energy spreads, validating our approach. These results naturally prompt the question of how IBS-induced degradation can be mitigated, both in future SwissFEL operation and in next-generation facilities. Leveraging the insights gained from our study, we identify key design principles for X-ray free-electron laser (XFEL) injectors aimed at suppressing slice energy spread growth. Furthermore, guided by this improved understanding, we propose and evaluate novel operational schemes for the electron source that enhance XFEL performance in the presence of IBS.
