The beam dump is a large graphite block used to take up the energy stored in the LHC beam in case the beam needs to be shut down. Since the energy in the beam can be as high as the kinetic energy of a landing 747-400, designing and operating the dump is challenging. In this episode, Marco Calviani, who heads the group that is responsible for this and other beam dumps at CERN, tells us about how the dump works, and what they have recently changed in order to cope with the higher luminosity in future configurations of the LHC.
