Incoherent electron cloud effects in the Large Hadron Collider

K. Paraschou, G. Iadarola
During the operation of the Large Hadron Collider in 2018, the majority of physics data was collected with a beam energy of 6.5 TeV, a bunch spacing of 25 ns and with β-functions in the high luminosity interaction points equal to 30 cm. In this configuration, it was found through several experimental measurements that electron cloud induces a significant degradation of the beam lifetime. This contribution reviews the available experimental observations, showing in particular the role played by
