FIB-SEM investigation and uniaxial compression of flexible graphite
/ Solfiti, Emanuele (Norwegian U. Sci. Tech.) ; Wan, Di (Norwegian U. Sci. Tech.) ; Celotto, Ambra (Norwegian U. Sci. Tech.) ; Solieri, Nicola (CERN) ; Munoz, Pablo Andreu (CERN) ; Ximenes, Rui Franqueira (CERN) ; Heredia, Jorge Maestre (CERN) ; Martin, Claudio Leopoldo Torregrosa (CERN) ; Nuiry, Antonio Perillo Marcone Francois-Xavier (CERN) ; Nuiry, F.X. (CERN) et al.
Flexible graphite (FG) with 1 - 1.2 g/cm$^3$ density is employed as beam energy absorber material in the CERN's Large Hadron Collider (LHC) beam dumping system. However, the increase of energy deposited expected for new HL-LHC (High-Luminosity LHC) design demanded for an improvement in reliability and safety of beam dumping devices, and the need for a calibrated material model suitable for high-level FE simulations has been prioritized.

CERN Linac4 Chopper Dump: Operational Experience and Future Upgrades
/ Sharp, Calum (CERN) ; Andreu Muñoz, Pablo (CERN) ; Calviani, Marco (CERN) ; Costa, Gabriele (CERN) ; Esposito, Luigi Salvatore (CERN) ; Franqueira Ximenes, Rui (CERN) ; Grenier, Damien (CERN) ; Grenier-Boley, Edouard (CERN) ; Hunt, James (CERN) ; Krainer, Alexander (CERN) et al.
The Chopper Dump in the Linac4 accelerator at CERN is a beam-intercepting device responsible for the absorption of the 3 MeV H⁻ ion beam produced by the Linac4 source and deflected upstream by an electromagnetic chopper. It allows a portion of the beam, which would otherwise fall into the unstable region of the radiofrequency buckets in the Proton Synchrotron Booster, to be dumped at low energy with minimal induced radiation.

Antiprotons are produced at CERN at the Antiproton Decelerator (AD) Target Area by impacting 26 GeV/c proton beams onto a fixed target. Further collection, momentum selection, and transport of the secondary particles - including antiprotons - towards the AD ring is realised by a 400 kA pulsed magnetic horn and a set of magnetic dipoles and quadrupoles.
