Radiation load studies for the proton target area of a multi-TeV muon collider
/ 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. [...]

Searching for the best initial beam parameters for efficient muon ionization cooling
/ Stechauner, Bernd (CERN ; TU Vienna) ; Fol, Elena (CERN) ; Rogers, Chris (Rutherford) ; Schieck, Jochen (Vienna, OAW ; TU Vienna) ; Schulte, Daniel (CERN)
Ionization cooling stands as the only cooling technique capable of efficiently reducing the phase space of a muon beam within a short time frame. The optimal cooling parameters of a muon collider aim to minimize transverse emittance while simultaneously limiting longitudinal emittance growth, resulting in optimal luminosities within the collider ring. [...]

Radiation shielding studies for superconducting magnets in multi-TeV muon colliders
/ Lechner, Anton (CERN) ; Amorim, David (CERN) ; Bottura, L (CERN) ; de Sousa, P Borges (CERN) ; Caiffi, B (INFN, Genoa) ; Calzolari, D (CERN) ; Carli, C (CERN) ; Ferreira Somoza, J (CERN) ; Frasca, A (CERN) ; Lerner, G (CERN) et al.
Circular muon colliders provide the potential to explore center-of-mass energies at the multi-TeV scale within a relatively compact footprint. Because of the short muon lifetime, only a small fraction of stored beam particles will contribute to the physics output, while most of the muons will decay in the collider ring. [...]

Multiturn simulation of radiative Bhabha scattering in the equivalent photon approximation
/ Kicsiny, Peter (CERN ; EPFL-ISIC, Lausanne) ; Buffat, Xavier (CERN) ; Schulte, Daniel (CERN) ; Burkhardt, Helmut (CERN) ; Pieloni, Tatiana (EPFL-ISIC, Lausanne) ; Seidel, Mike (EPFL-ISIC, Lausanne)
In this paper, we present a Monte Carlo event generator for radiative Bhabha scattering, based on the method of equivalent photons, and optimized for multiturn tracking simulations in the xsuite framework. We demonstrate the accuracy of the event generator with successful benchmarks of the luminosity and event cross section against currently existing alternative tools. [...]

Dielectric laser acceleration (DLA) is a promising approach to accelerate single electrons at a high repetition rate to GeV energies, for indirect dark matter searches. Relevant concepts include the integration of the dielectric structure inside the laser oscillator. [...]

Transverse Coherent Instability Studies for the High-Energy Part of the Muon Collider Complex

The International Muon Collider Collaboration (IMCC) is studying a 3 TeV center-of-mass muon collider ring, as well as a possible next stage at 10 TeV. Muons being 200 times heavier than electrons, limitations from synchrotron radiation are mostly suppressed, but the muon decay drives the accelerator chain design. [...]
