/ 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. [...]

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.

Simulations of longitudinal beam stabilisation in the CERN SPS with BLonD
/ Repond, Joël (CERN ; Ecole Polytechnique, Lausanne) ; Iliakis, Konstantinos (CERN) ; Schwarz, Markus (CERN) ; Shaposhnikova, Elena (CERN)
The Super Proton Synchrotron (SPS) at CERN, the Large Hadron Collider (LHC) injector, will be pushed to its limits for the production of the High Luminosity LHC proton beam while beam quality and stability in the longitudinal plane are influenced by many effects. Particle simulation codes are an essential tool to study the beam instabilities. [...]

Qualification and Calibration of Single-Mode Phosphosilicate Optical Fiber for Dosimetry at CERN
/ Di Francesca, Diego (CERN) ; Li Vecchi, Gaetano (CERN) ; Girard, Sylvain (St. Etienne U.) ; Morana, Adriana (St. Etienne U.) ; Reghioua, Imene (St. Etienne U.) ; Alessi, Antonino (St. Etienne U.) ; Hoehr, Cornelia (TRIUMF) ; Robin, Thierry (Unlisted, FR) ; Kadi, Yacine (CERN) ; Brugger, Markus (CERN)
We report the results of several complementary radiation tests to qualify and calibrate a highly radiation sensitive Single-Mode (SM) Optical Fiber (OF) for distributed dosimetry application at CERN. The Radiation Induced Attenuation (RIA) is the physical phenomenon used to evaluate the Total Ionizing Dose (TID) received by the OF sensor. [...]

Recent beam performance achievements with the Pb-ion beam in the SPS for LHC physics runs
/ Bartosik, Hannes (CERN) ; Alemany-Fernández, Reyes (CERN) ; Argyropoulos, Theodoros (CERN) ; Bohl, Thomas (CERN) ; Damerau, Heiko (CERN) ; Kain, Verena (CERN) ; Papotti, Giulia (CERN) ; Rumolo, Giovanni (CERN) ; Saá Hernández, Angela (CERN) ; Shaposhnikova, Elena (CERN)
In the SPS, which is the last accelerator in the LHC ion injector chain, multiple injections of the Pb-ion beam have to be accumulated. On this injection plateau the beam suffers from considerable degradation such as emittance growth and losses. [...]

Beam-beam blowup after low-emittance tuning for FCC-ee
/ El Khechen, Dima (CERN) ; Oide, Katsunobu (KEK, Tsukuba ; CERN) ; Zimmermann, Frank (CERN)
FCC-ee (Future Circular Collider) is a 100 km electron-positron circular collider with two foreseen experiments, aiming to run at four energies for precision studies of the Z, W, and Higgs boson and the top quark. The FCC-ee is a challenging machine from different points of view. [...]

Longitudinal mode-coupling instability: GALACLIC Vlasov solver vs. macroparticle tracking simulations
/ Métral, Elias (CERN) ; Migliorati, Mauro (U. Rome La Sapienza (main))
Following the same approach as for the recently developed GALACTIC Vlasov solver in the transverse plane and taking into account the potential-well distortion, a new Vlasov solver, called GALACLIC, was developed for the longitudinal plane. In parallel, a new mode analysis was implemented for the post-processing of the results obtained through macroparticle tracking simulations. [...]

GALACTIC and GALACLIC: Two Vlasov solvers for the transverse and longitudinal planes
/ Métral, Elias (CERN)
GALACTIC and GALACLIC, two Vlasov solvers for the study, in the transverse and longitudinal plane respectively, of single-bunch coherent oscillation modes, were recently developed starting from the Vlasov equation and using a decomposition on the low-intensity eigenvectors, as proposed by Laclare and Garnier. The first Vlasov solver was used for instance to shed light on the destabilising effect of resistive transverse dampers and the second helped understanding the details of the mode-coupling behind some longitudinal microwave instabilities.
