The beam dynamics case of beam-beam wire compensators for the HL-LHC era / Bélanger, Philippe (TRIUMF ; U. British Columbia (main)) ; Kaltchev, Dobrin (TRIUMF) ; Sterbini, Guido (CERN) ; Baartman, Rick (TRIUMF)
Beam-beam long-range interactions are known to be a strong source of non-linearities in hadron colliders, undermining the performance of the LHC during proton-proton collisions. In order to enhance the luminosity production of the machine and increase the tolerance of the working point after the High Luminosity upgrade of the LHC (HL-LHC), dedicated correctors such as beam-beam wire compensators can be used.

Significance of Corrosion Phenomena for Magnets of Accelerators, Fusion and High Energy Physics Experiments / Sgobba, Stefano (CERN) ; Aviles Santillana, Ignacio (CERN) ; Fontenla, Ana Teresa Perez (CERN) ; Koizumi, Norikiyo (Natl. Inst. Quantum Radiological Sci. Tech., Chiba) ; Pearce, Robert (Euratom, St. Paul Lez Durance) ; Villers, Frantz (Euratom, St. Paul Lez Durance) ; Vitupier, Guillaume (Euratom, St. Paul Lez Durance)
Although superconducting accelerator and fusion magnets operate at cryogenic temperature and in most cryogenic applications corrosion is not an issue, it is essential to avoid corrosion phenomena that may occur during production and fabrication of parts and components of magnet systems, or during their installation, assembly or maintenance. A delayed leak or a structural failure that would arise in operation due to onset of corrosion phenomena at an earlier stage could lead to grave consequences due to many such components becoming embedded and virtually unrepairable.

Beam-based impedance measurement of HL-LHC low-impedance collimators / Kurtulus, A (Zurich, ETH ; CERN) ; Amorim, D (CERN) ; Biancacci, N (CERN) ; Buffat, X (CERN) ; Giacomel, L (CERN) ; Leuthold, J (Zurich, ETH) ; Mounet, N (CERN) ; Redaelli, S (CERN) ; Smajic, J (Zurich, ETH)
The objective of the High Luminosity Large Hadron Collider (HL-LHC) upgrade is to attain an instantaneous luminosity that is 5 times greater than the design value of the LHC. This requires nearly 2 times higher beam intensity compared to the operational LHC value during Run 2 (2015–2018). [...]

Rapid event extraction and tensorial event adaption: Libraries for efficient access and generic reweighting of parton-level events and their implementation in the MadtRex module / Roiser, Stefan (CERN) ; Schöfbeck, Robert (Vienna, OAW) ; Wettersten, Zenny (CERN ; Vienna, OAW)
We present Rex and teaRex, C++17 libraries for efficient management of parton-level hard scattering event information and completely generic reweighting of such events, respectively. [...]

Batch spacing optimization by reinforcement learning / Remta, Matthias (CERN) ; Velotti, Francesco (CERN) ; Rezagholi, Sharwin (Unlisted, AT)
Beams designated for the LHC are injected into the SPS in multiple batches. Given the tight spacing of 200 ns between these batches, the injection kickers have to be precisely synchronized with the injected beam to minimize injection oscillations. [...]
