Description
In the Large Hadron Collider (LHC), two beam dumps (TDEs) ensure the safe and reliable disposal of the extracted beams. During Run 4, the stored beam energy will increase from 490 MJ achieved so far during Run 3 to a maximum of 710 MJ. A new design, capable of withstanding the increase in dump energy, is therefore presented for the High Luminosity LHC (HL-LHC) TDEs. This contribution includes an analysis of the beam energy actually dumped during Run 3, and presents energy deposition studies on the new design of the HL-LHC TDE. The energy absorption breakdown between the main components of the new TDE is presented, as well as the leakage to the surrounding shielding and cavern. Transverse and longitudinal peak energy densities are also shown, for standard dump events and considering failure scenarios in the beam dilution system.
