In order to make full use of the physics potential of the LHC, an increase of the luminosity by at least a factor of 5 is planned within the High-Luminosity LHC (HL-LHC) project.
The project includes increasing the bunch intensity, adding so-called crab cavities, and replacing the magnets in the high luminosity interaction regions for the ATLAS and CMS experiments. The increased beam intensity implies a doubling of the stored energy in the beam to 700 MJ, which leads to the risk of having a fatal incident for the LHC in the case of uncontrolled beam loss due to for example fast failure of an accelerator magnet or a crab cavity.
A number of different failure scenarios have been studied both theoretically and through experiments in the LHC, and are presented in this talk. Their impact on the beam and the accelerator is discussed and the proposed machine protection strategy, based on mitigation of the failures and appropriate interlocking, is presented.
