Detection and Analysis of Uncontrolled Beam Loss in the High Luminosity LHC

Mid-term seminar

In order to make full use of the physics potential of the LHC, an increase of the luminosity by at least a factor 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 will be presented in this talk, including an outlook on the analysis that is still ongoing.
