Electron cloud in 2016: Cloudy or clear?

The proton physics run in 2015 confirmed that electron cloud poses a significant challenge to LHC operation with beams of 25 ns bunch spacing. Despite evident conditioning of the electron cloud during the 2015 Run, full suppression did not occur, and hence also the 2016 proton physics Run suffered t...

description The proton physics run in 2015 confirmed that electron cloud poses a significant challenge to LHC operation with beams of 25 ns bunch spacing. Despite evident conditioning of the electron cloud during the 2015 Run, full suppression did not occur, and hence also the 2016 proton physics Run suffered the presence of e-cloud. This contribution reviews the electron cloud situation throughout the 2016 Run. The conditions at the beginning of the run, including the scrubbing and intensity ramp-up, are covered and compared to 2015. Studies and observations of the evolution during the run are described, along with ongoing efforts to interpret them. Finally, some future implications are discussed. Detailed considerations and plans for 2017 operation are presented elsewhere [1].
