Advancing Beam Energy Absorption in the Large Hadron Collider: Evolution of Beam Dumps Design and Operation From LHC Construction to High Luminosity LHC | |
|
||
| Two 6-tonne beam dumps are employed to absorb the energy of the two Large Hadron Collider (LHC) intense 7 TeV/c proton beams. Originally designed to handle approximately 300 MJ of energy deposited per dump event, the capacity of these dumps has grown over the lifespan of the LHC due to upgrades aimed at enhancing the machine’s scientific potential. In the era of the High Luminosity LHC (HL-LHC), the dumps will need to withstand energy absorptions of up to 700 MJ per dump. Several upgrades and interventions, such as adjustments to the outer vessel and supporting structure as well as enhancements to online instrumentation, have been executed since the initial installation of the beam dumps. In addition, significant advancements in simulation techniques have been implemented to gain a deeper understanding of the intricate dynamics of high-energy beam absorption and the resulting thermo-mechanical repercussions. Lessons learnt have been acquired also thanks to a first-of-a-kind autopsy. This contribution will present a comprehensive overview of the design, operational experiences, and evolutionary journey of the main absorber within the Large Hadron Collider. | ||
