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. [...]

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. (CERN) ; Bracco, C. (CERN) ; Coiffet, T. (CERN) ; Ferrari, M. (CERN) ; Ximenes, R. Franqueira (CERN) ; Gilardoni, S. (CERN) ; Grenier, D. (CERN) ; Lechner, A. (CERN) et al.
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 operation in 2016 was limited by the constraints on the maximum allowed intensity in the SPS due to the vacuum leak at the internal dump. The present baseline foresees the replacement of the T1DVG with a new upgraded hardware during the upcoming EYETS. [...]

Beam Intercepting Devices at CERN – Types, Challenges, Design, R&D and Operation / Calviani, Marco (speaker) (CERN)
Beam-intercepting systems are essential devices designed to absorb the energy and power of a particle beam. Generally, they are classified in three categories depending on their use: particle-producing devices, such as targets; systems for beam cleaning and control, such as collimators or scrapers; and those with safety functions, such as beam dumps or beam stoppers.  Beam-intercepting devices have to withstand enormous mechanical and thermally-induced stresses [...]

Energy deposition challenges for the HL-LHC beam dump / Farina, E (CERN) ; Banks, T G (CERN) ; Bracco, C (CERN) ; Calviani, M (CERN) ; Dutheil, Y (CERN) ; Lechner, A (CERN) ; Solieri, N (CERN)
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. [...]
