/ Manczak, Jerzy (CERN) ; Frasca, Alessandro (CERN) ; Portone, Alfredo (Fusion for Energy, Barcelona) ; Lechner, Anton (CERN) ; Rogers, Chris (Daresbury) ; Ahdida, Claudia (CERN) ; Schulte, Daniel (CERN) ; Calzolari, Daniele (CERN) ; Saura Esteban, Francisco Javier (CERN) ; Bottura, Luca (CERN) et al.
Muon production in the multi-TeV muon collider studied by the International Muon Collider Collaboration is planned to be performed with a high-power proton beam interacting with a fixed target. The design of the target area comes with a set of challenges related to the radiation load to front-end equipment. [...]

Findings of the Physics Beyond Colliders ECN3 Beam Delivery Task Force
/ Ahdida, Claudia (CERN) ; Bartosik, Hannes (CERN) ; Bernhard, Johannes (CERN) ; Brugger, Markus (CERN) ; Calviani, Marco (CERN) ; Colinet, Antoine (CERN) ; Esposito, Luigi Salvatore (CERN) ; Franqueira Ximenes, Rui (CERN) ; Fraser, Matthew Alexander (CERN) ; Gautheron, Fabrice (University of Patras (GR)) et al.
The ECN3 Beam Delivery Task Force was mandated by the PBC Study Group to assess the technical feasibility of increasing the proton beam intensity to the ECN3 hall of the North Area to satisfy the demands of a compelling set of PBC experimental physics proposals. This report summarises the findings of the Task Force that converge on a technically feasible solution with an implementation timeline that could exploit and build upon the investment already foreseen as part of Phase 1 of the NA-CONS project, and take the SPS complex into a new intensity frontier for Fixed Target physics in Run4..

CERN Linac4 Chopper Dump: Operational Experience and Future Upgrades
/ Sharp, Calum (CERN) ; Andreu Muñoz, Pablo (CERN) ; Calviani, Marco (CERN) ; Costa, Gabriele (CERN) ; Esposito, Luigi Salvatore (CERN) ; Franqueira Ximenes, Rui (CERN) ; Grenier, Damien (CERN) ; Grenier-Boley, Edouard (CERN) ; Hunt, James (CERN) ; Krainer, Alexander (CERN) et al.
The Chopper Dump in the Linac4 accelerator at CERN is a beam-intercepting device responsible for the absorption of the 3 MeV H⁻ ion beam produced by the Linac4 source and deflected upstream by an electromagnetic chopper. It allows a portion of the beam, which would otherwise fall into the unstable region of the radiofrequency buckets in the Proton Synchrotron Booster, to be dumped at low energy with minimal induced radiation.

Towards the Last Stages of the CERN’s AD-Target Area Consolidation Project and Recommissioning Plans to Resume Operation
/ Torregrosa, Claudio (CERN) ; Ahdida, Claudia (CERN) ; Bouvard, Aymeric (CERN) ; Broche, Alexandre (CERN) ; Burger, Stephane (CERN) ; Butcher, Mark (CERN) ; Calviani, Marco (CERN) ; Clerc, Vincent (CERN) ; De Macedo, Aurelio (CERN) ; De Man, Sven (CERN) et al.
Antiprotons are produced at CERN at the Antiproton Decelerator (AD) Target Area by impacting 26 GeV/c proton beams onto a fixed target. Further collection, momentum selection, and transport of the secondary particles - including antiprotons - towards the AD ring is realised by a 400 kA pulsed magnetic horn and a set of magnetic dipoles and quadrupoles.
