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.

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.

The FCCee Pre-Injector Complex

The international FCC study group published in 2019 a Conceptual Design Report for an electron-positron collider with a centre-of-mass energy from 90 to 365 GeV with a beam currents of up to 1.4 A per beam. The high beam current of this collider create challenging requirements on the injection chain and all aspects of the linac need to be carefully reconsidered and revisited, including the injection time structure.

Studies on Top-Up Injection into the FCC-ee Collider Ring

In order to maximize the luminosity production time in the FCC-ee, top-up injection will be employed. The positron and electron beams will be accelerated to the collision energy in the booster ring before being injected with either a small transverse or longitudinal separation to the stored beam.

For the LHC injectors upgrade (LIU) at CERN, the two PS (Proton Synchrotron) dumps will be redesigned and upgraded for the new high intensity beams. The EN-STI group is in charge of the design and installation of the new dumps, foreseen for the next CERN's Long Shutdown in 2019-2020. [...]
