Electron cloud eects have been identified as one of the main performance limitations for some of the synchrotrons of the CERN accelerator complex. The tools for the simula- tion of the electron cloud build-up and its eects on beam stability have significantly evolved in recent years, leading to a much better understanding of all machine observations. At the same time, electron cloud mitigation measures have been tested (e.g. surface treatments) and implemented in operation (e.g. beam induced scrubbing). The combination of a deeper understanding of the electron cloud and a handle on its mitigation has been the key to reach and exceed the nominal luminosity in the LHC during Run 2 as well as to define strategies to cope with the High Luminosity (HL) operation of the LHC as from 2026.
