LHC Powering Issues – Review of Beam Dumps

Research output: Chapter in Book/Report/Conference proceedingConference contribution


Following the near catastrophic quench event in September 2008, the LHC magnets have seen their magnetic field strength reduced to a maximum safe value, limiting the LHC’s beam energy. Since then, the challenge of establishing the causes of such an event and ensuring that it is not likely to reoccur has been of paramount priority. The main topic of this paper is to discuss the significant powering issues and causes of beam dumps over the last three years of operation, correlating individual system statistics, year-to-year, with
intermittent system changes/upgrades. To complement this, predictions of the systems most likely to cause issues whilst operating at higher energies will be discussed, as well as a brief look at past ‘near-miss’ events, their causes, and plans for prevention of future reoccurrence
