Report from the Conventional Beams Working Group to the Physics Beyond Colliders Study and to the European Strategy for Particle Physics / Bernhard, Johannes (CERN) ; Banerjee, Dipanwita (CERN) ; Baratto Roldan, Anna (CERN) ; Brugger, Markus (CERN) ; Charitonidis, Nikolaos (CERN) ; d'Allesandro, Gian Luigi (CERN) ; Van Dijk, Maarten (CERN) ; Doble, Niels (CERN) ; Dyks, Luke Aidan (University of Oxford (GB)) ; Gatignon, Lau (Lancaster University (GB)) et al.
This document summarises the main conclusions of the Conventional Beams Working group, which has analysed the beam-related and technical requirements and requests in the proposals to the Physics Beyond Colliders study, mainly for the North Area at the CERN SPS. We present results from studies on feasibility, requirements, compatibility between proposals and, where possible, the order of magnitude of the costs. [...]

Modeling X-Y Beam Distributions via Crossing of Coupled Resonances in an Accelerator Complex / Lamb, Elleanor
Key words: luminosity, van der Meer, non-factorization, resonance, calibration, losses In high-energy colliders, discoveries are made possible by improving precision and accuracy of the measured rare events. Precision is maximized by increasing the collider integrated luminosity, whereas accuracy is addressed by minimizing the systematic errors via ad-hoc luminosity calibrations of the detectors. [...]

Need of reference proton data for the DICE/NA60+ experiment / Scomparin, Enrico (Universita e INFN Torino (IT)) ; Usai, Gianluca (Universita e INFN, Cagliari (IT))
In this document we motivate the need for data taking in proton-nucleus at collision energies per incident nucleon corresponding to those of nucleus-nucleus interactions. With a non-expert audience in mind, we show that this is a general requirement for all experiments working with relativistic heavy-ion collisions and further demonstrate this case for a few observables that are crucial for the NA60+ experiment at the CERN SPS..

Status and challenges of Nb$_3$Sn accelerator magnets at CERN : Lessons learned from ITER to HL-LHC / Devred, A
The High-Luminosity Large Hadron Collider (HL-LHC) project at CERN has offered the opportunity to promote and develop various types of enabling accelerator technologies, such as MgB$_2$ superconducting links for cold powering and Nb$_3$Sn accelerator magnets for the interaction regions where the t [...]

Development of SLA 3D printed volumes for leak testing of LHC Hi-Lumi cryomodules at STFC / Poynton, J O W (Daresbury) ; Wilde, S (Daresbury) ; Bourne, J (Daresbury) ; Jordan, E (Daresbury) ; Templeton, N (Daresbury) ; Matheson, B (TRIUMF) ; Capelli, T (CERN) ; Seller, A (CERN)
Daresbury Laboratory recently completed the build of a Radio Frequency Dipole (RFD) crab cavity cryomodule for the Super Proton Synchrotron (SPS). During the build the team faced challenges leak testing welds which could not be tested in the typical evacuation method. [...]
