Beam Loss Consequences / Lerner, Giuseppe (CERN)
The operation of high-energy and high-intensity particle accelerators inevitably leads to the loss of a fraction of beam particles, either through controlled processes or accidental events. [...]

LHC Magnetic Model Revisited: Beam-Based Measurements and Machine Reproducibility at Injection / Wanczyk, Joanna ; Fiscarelli, Lucio (CERN) ; Hostettler, Michi (CERN) ; Solfaroli Camillocci, Matteo (CERN) ; Trad, Georges (CERN) ; Wenninger, Jorg (CERN)
The harmonic components of the LHC superconducting magnets exhibit a characteristic decay at low field, primarily caused by current redistribution within the superconducting cables, inducing dynamic changes in the beam tune and chromaticity during the injection plateau. [...]

III.14 - CERN beamline for fixed-target experiments / Gerbershagen, Alexander (U. Groningen (main))
Fixed-target experiments are continuing to play a major role in the very beginnings of accelerator-based studies in particle physics. While collider experiments dominate the exploration in the high-energy domain, fixed-target experiments still cover the important complementary domain, as they permit experiments with extremely high event rates. [...]

The future circular collider in Europe / Zimmermann, Frank (CERN) ; Benedikt, Michael (CERN)
The proposed Future Circular Collider (FCC) integrated programme consists of two stages: An electron–positron collider serving as a highest-luminosity Higgs-boson, electroweak and top-quark factory, followed by a proton–proton collider with a collision energy around 100 TeV. In 2021, the CERN Council initiated the FCC Feasibility Study. [...]
