Design development and R&D; for CERN’s HL-LHC external beam dump / Banks, G (CERN) ; Bracco, C (CERN) ; Calviani, M (CERN) ; Farina, E (CERN) ; Gross, L (CERN) ; Lechner, A (CERN) ; Lund, A (CERN) ; Solieri, N (CERN)
The energy contained in the LHC's two beams must be safely absorbed in external beam dumps (TDE). High Luminosity (HL) is a future upgrade which will increase this stored energy to 700 MJ, compared to 150 MJ in Run 1. [...]

The LHC beam dump system has the task of safely and reliably disposing of the extracted beams from 450 GeV to 7 TeV. The present dump assembly consists of a multi-segment graphite core, which is contained in a duplex stainless steel vessel with titanium windows. [...]

The Large Hadron Collider (LHC) beam dump (TDE) is essential for safe and reliable operation of the collider. It absorbs particles extracted from the accelerator whenever required. [...]

Design and behaviour of the Large Hadron Collider external beam dumps capable of receiving 539 MJ/dump / Maestre, J. (CERN ; Granada U.) ; Torregrosa, C. (CERN ; Granada U.) ; Kershaw, K.

Two 6-t beam dumps, made of a graphite core encapsulated in a stainless steel vessel, are used to absorb the energy of the two Large Hadron Collider (LHC) intense proton beams during operation of the accelerator. Operational issues started to appear in 2015 during LHC Run 2 (2014-2018) as a consequence of the progressive increase of the LHC beam kinetic energy, necessitating technical interventions in the highly radioactive areas around the dumps.

LHC Dump Assembly - Operational Feedback and Future Prospective / Perillo-Marcone, A (CERN) ; Calviani, M (CERN) ; Grenier, D (CERN) ; Kershaw, K (CERN) ; Polzin, T (CERN)
The current LHC external beam dumps (TDE, Target Dump External) are operational since 2008. The dump cores are 7.6 m long and made up of different grades of graphite, enclosed in a duplex stainless steel vessel, welded together in different sections. [...]

Irradiation of Low-Z Carbon-Based Materials with 440 GeV/c Proton Beam for High Energy & Intensity Beam Absorbers: The CERN HiRadMat-56-HED Experiment / Andreu Muñoz, Pablo (CERN) ; Calviani, Marco (CERN) ; Charitonidis, Nikolaos (CERN) ; Cherif, Ahmed (CERN) ; Farina, Edoardo (CERN) ; Krainer, Alexander (CERN) ; Lechner, Anton (CERN) ; Maestre, Jorge (CERN) ; Nuiry, Francois-Xavier (CERN) ; Seidenbinder, Regis (CERN) et al.
The beam stored energy and the peak intensity of CERN Large Hadron Collider (LHC) will grow in the next few years. The former will increase from the 320 MJ values of Run2 (2015-2018) to almost 540 MJ during Run3 (2022 onwards) and 680 MJ during the HL-LHC era putting stringent requirements on beam intercepting devices, such as absorbers and dumps.

A Large Diameter Entrance Window for the LHC Beam Dump Line / Presland, Andrew ; Goddard, Brennan ; Jiménez, J M ; Ramos, D ; Veness, Raymond
The graphite LHC beam dump block TDE has to absorb the full LHC beam intensity at 7 TeV. The TDE vessel will be filled with inert gas at atmospheric pressure, and requires a large diameter entrance window for vacuum separation from the beam dumping transfer line. [...]
