Design and optimisation of a variable momentum secondary beamline for the NP06/ENUBET project / Parozzi, Elisabetta Giulia (Universita & INFN, Milano-Bicocca (IT))
The precision of the measurement of the cross-section of the electronic and muon neutrino is mainly limited by the knowledge of the initial flux. The current precision is on the order of 5−10%. [...]

LHC Triplet Task Force Report / Arduini, Gianluigi (CERN) ; Bradu, Benjamin (CERN) ; Brodzinski, Krzysztof (CERN) ; Bruce, Roderik (CERN) ; Cerutti, Francesco (CERN) ; Ciccotelli, Alessia (University of Manchester (GB)) ; Deferne, Guy (CERN) ; Fartoukh, Stephane (CERN) ; Fessia, Paolo (CERN) ; Garion, Cedric (CERN) et al.
The excellent performance of the Large Hadron Collider (LHC) and the extension of Run 3 by one year have led to a significant increase of the expected integrated luminosity by the end of its operation and before the start of the High Luminosity LHC (HL-LHC), exceeding the design LHC integrated luminosity of 300 fb−1 for which the final focus region has been designed.

Particle-in-Cell Simulations of Plasma Density Variations in a Proton-Driven Wakefield Accelerator / Morales Guzman, Pablo Israel (Max Planck Society (DE))
Plasma Wakefield Accelerators (PWFA) use relativistic particle bunches to drive high-amplitude (GV/m) wakefields to accelerate other particle bunches. I use particle-in-cell simulations to study the physics behind a PWFA driven by a long proton that relies on self-modulation (SM). [...]

Automated Evaluation of LHC Beam Losses during High Energy Proton Dumps / Ziegler, Philipp (Universität Regensburg)
All high-energy beam dump events at the Large Hadron Collider (LHC) are analysed to verify correct functioning of the Machine Protection System and to allow early identification of potential issues. These checks are partially automated. [...]

Systematic Errors of a ”frozen Spin” EDM measurement with electric and magnetic Fields due to imperfect Alignment of Fields / Cilento, Vera (CERN) ; Carli, Christian (CERN) ; Haj Tahar, Malek
Many of the rings proposed to measure the Electric Dipole Moment (EDM) of charged particles rely on a combination of magnetic and electric fields bending the beam to fulfil the ”frozen spin” condition. Imperfect alignment of the two fields bending the beam is known to rotate the spin from the longitudinal into the vertical direction. [...]

Feasibility of using crystal channeling for the beam loss mitigation in slow extraction at 8GeV / Nagaslaev, V (Fermilab) ; Tropin, I (Fermilab) ; Esposito, L (CERN) ; Fraser, M (CERN) ; Goddard, B (CERN) ; Velotti, F (CERN) ; Bandiera, L (Ferrara U.) ; Guidi, V (Ferrara U.) ; Mazzolari, A (Ferrara U.) ; Romagnoni, M (Ferrara U.) et al.
In the accelerator applications of slow extraction for High Energy Physics (HEP), one of the prime challenges is the mitigation of beam losses, which is becoming increasingly critical with the continuous rise in beam power. A significant breakthrough was achieved earlier at CERN through the successful deployment of proton beam channeling in a crystal at 400 GeV, effectively diverting the beam away from extraction septa and offering new avenues for improving slow extraction efficiency.
