Description
This contribution reviews high-intensity and high-brightness effects through the CERN accelerator complex, from the H- and heavier ions' sources/linacs to the injector synchrotrons and the Large Hadron Collider (LHC), for several beam flavours and physics users. It covers various beam dynamics limitations and mitigations applied in order to reach high beam performance while maintaining low losses, for the lowest emittances, as foreseen by the LHC injector upgrade but also for Physics Beyond Collider project and towards High-Luminosity LHC. These simulations and experimental efforts for beam optimisation include optics and single particle effects coupled with incoherent collective effects such as Intrabeam-Scaterring and space-charge, coherent collective effects (instabilities, beam induced heating, e-cloud) but also beam loss handling and collimation. Prospects for the final Run 3 year (2026) but also Run 4, after the Long Shutdown 3 (LS3) are finally summarised.
