First operational experience with data-driven hysteresis compensation for the main dipole magnets of the CERN SPS
/ Lu, Anton (CERN ; Vienna, Tech. U.) ; Kain, Verena (CERN) ; Petrone, Carlo (CERN) ; Di Capua, Vincenzo (CERN) ; Schenk, Michael (CERN) ; Zannini, Carlo (CERN)
Magnetic hysteresis, eddy currents, and manufacturing imperfections pose significant challenges for beam operation in multi-cycling synchrotrons. Addressing the dynamic dependency of magnetic fields on cycling history is a current limitation for control room tools using existing models. [...]

Correlating start-of-ramp losses with beam observables at blat-bottom in the LHC
/ Karlsen-Bæck, Birk Emil (CERN ; Rome U.) ; Salvachua, Belen (CERN) ; Timko, Helga (CERN) ; Zampetakis, Michail (CERN) ; Morales Vigo, Sara (CERN)
Power limitations are expected at injection energy for the main Radio Frequency (RF) system due to the doubled bunch intensity in the High Luminosity (HL-) Large Hadron Collider (LHC) era. One way to overcome these power limitations is to reduce the capture voltage. [...]

Simulated impact of the HL-LHC beam on a graphite target

In the High Luminosity Large Hadron Collider (HL-LHC) era, the intensity of the circulating bunches will increase to 2.2e+11 protons per bunch, almost twice the nominal LHC value. Besides detailed studies of known and new failure cases for HL-LHC, it is also required to investigate failures beyond nominal design. [...]

Development of numerical tools for intra-beam scattering modelling
/ Soubelet, Felix (CERN) ; Bartosik, Hannes (CERN) ; Kostoglou, Sofia (CERN) ; Paraschou, Konstantinos (CERN) ; Zampetakis, Michail (CERN) ; Iadarola, Giovanni (CERN)
Intra-beam Scattering (IBS) is one of the main mechanisms of emittance blowup and performance deterioration in the Large Hadron Collider (LHC) accelerator complex. It is particularly relevant since the recent upgrades across the injector complex to reach the high brightness beams of the High Luminosity LHC (HL-LHC) era have been implemented. [...]

Luminosity effects due to dependent heavy-tailed beams
/ Lamb, Elleanor (Ecole Polytechnique, Lausanne ; CERN) ; Sterbini, Guido (CERN) ; Bartosik, Hannes (CERN)
The luminosity of particle colliders depends, among other parameters, on the transverse profiles of the colliding beams. At the LHC at CERN, heavy-tailed transverse beam distributions are typically observed in routine operation. [...]
