LHC MD4243: Q22 optics in TI2
/ Velotti, Francesco Maria (CERN) ; Bartmann, Wolfgang (CERN) ; Bracco, Chiara (CERN) ; Goddard, Brennan (CERN) ; Hessler, Christoph ; Kain, Verena (CERN) ; Chapochnikova, Elena (CERN) ; Timko, Helga (CERN)
This MD shows the feasibility of operating TI2 with an optics matched to the SPS Q22 optics.Optics studies in the transfer line (TL) were performed together with an injection voltage scan toassess, also, the longitudinal quality of the injected single bunch..

Beam steering performance of bent silicon crystals irradiated with high-intensity and high-energy protons
/ Scandale, W (CERN) ; Calviani, M (CERN) ; D'Andrea, M (CERN) ; Esposito, L S (CERN) ; Garattini, Marco (CERN ; Imperial Coll., London) ; Gilardoni, S (CERN) ; Montesano, S (CERN) ; Natochii, A (CERN ; Orsay, LAL ; Taras Shevchenko U.) ; Rossi, R (CERN) ; Smirnov, G I (CERN ; Dubna, JINR) et al.
Beam steering performance of bent silicon crystals irradiated with high-intensity and high-energy protons has been studied. In particular, crystals of the type used for collimation and extraction purposes in the Large Hadron Collider and the Super Proton Synchrotron at CERN have been irradiated at the HiRadMat CERN facility with $2.5 \times 10^{13}$ 440 GeV/c protons, with a pulse length of 7.2 $\upmu $s.

Design and operation of the air-cooled beam dump for the extraction line of CERN's Proton Synchrotron Booster (PSB)
/ Perillo-Marcone, Antonio (CERN) ; Calviani, Marco (CERN) ; Solieri, Nicola (CERN) ; Kaiser, Paul (CERN) ; Sarrio, Alba (CERN) ; Venturi, Valentina (CERN) ; Vlachoudis, Vasilis (CERN)
A new beam dump has been designed, built, installed and operated to withstand the future proton beam extracted from the Proton Synchrotron Booster (PSB) in the framework of the LHC Injector Upgrade (LIU) Project at CERN, consisting of up to 1E14 protons per pulse at 2 GeV, foreseen after the machine upgrades planned for CERN's Long Shutdown 2 (2019-2020).

SixTrack project: Status, runtime environment, and new developments
/ De Maria, Riccardo (CERN) ; Andersson, Joel (CERN) ; Field, Laurence (CERN) ; Giovannozzi, Massimo (CERN) ; Hermes, Pascal (CERN) ; Hoimyr, Nils (CERN) ; Iadarola, Giovanni (CERN) ; Kostoglou, Sofia (CERN) ; Maclean, Ewen (CERN ; U. Malta) ; McIntosh, Eric (CERN) et al.
SixTrack is a single-particle tracking code for high-energy circular accelerators routinely used at CERN for the Large Hadron Collider (LHC), its luminosity upgrade (HL-LHC), the Future Circular Collider (FCC), and the Super Proton Synchrotron (SPS) simulations. The code is based on a 6D symplectic tracking engine, which is optimised for long-term tracking simulations and delivers fully reproducible results on several platforms. [...]

Muon background studies for beam dump operation of the K12 beam line at CERN
/ Rosenthal, Marcel (CERN) ; Banerjee, Dipanwita (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; Döbrich, Babette (CERN) ; Gatignon, Laurent (CERN) ; Gerbershagen, Alexander (CERN) ; Montbarbon, Eva (CERN) ; Rae, Bastien (CERN) et al.
In the scope of the Physics Beyond Colliders study at CERN a future operation of the NA62 experiment in beam dump mode is discussed, enabling the search for dark sector particles, e.g. heavy neutral leptons, dark photons and axions. [...]

Space charge and transverse instabilities at the CERN SPS and LHC
/ Métral, Elias (CERN) ; Amorim, David (CERN) ; Arduini, Gianluigi (CERN) ; Bartosik, Hannes (CERN) ; Benedetto, Elena (CERN) ; Burkhardt, Helmut (CERN) ; Li, Kevin (CERN) ; Oeftiger, Adrian (CERN) ; Quatraro, Diego (CERN) ; Rumolo, Giovanni (CERN) et al.
At the CERN accelerator complex, it seems that only the highest energy machine in the sequence, the LHC, with space charge (SC) parameter close to one, sees the predicted beneficial effect of SC on transverse coherent instabilities. In the other circular machines of the LHC injector chain (PSB, PS and SPS), where the SC parameter is much bigger than one, SC does not seem to play a major (stabilising) role, and it is maybe the opposite in the SPS.
