Computational studies have shown that potentially MeV-range swift heavy ions (SHIs) occur in titanium under GeV-range proton irradiation, which reflects the operating conditions of one of the muon collider's proton beam windows. To gain a better understanding of the effects of these on the atomic structure of the window, the development of accurate computational SHI models in HCP titanium is...

A study of cluster reconstruction and calibration optimization for the MAIA detector concept is presented. Single-particle samples of pions, neutrons, and electrons were simulated across multiple energies and detector regions with and without beam-induced background. Reconstructed cluster response in the ECAL and HCAL was evaluated using a cluster-matching framework based on angular separation...

The final cooling section of a muon collider accelerator complex requires low emittance muon beams in order to achieve the high luminosities needed at the interaction point in the collider ring. The objective of the final cooling stage is to minimize the transverse emittance while limiting the growth of the longitudinal emittance.

High-gradient RF cavities are essential components of the cooling channel for a muon collider, where they restore longitudinal momentum during ionization cooling. The compact lattice geometry and strong magnetic focusing impose strict constraints on cavity integration, motivating the investigation of dielectric-loaded RF structures as a compact alternative to conventional vacuum cavities....

Towards the construction of a muon cooling demonstrator, substantial R&D is needed to validate its key technologies and their integration in a compact cooling cell layout. A key step in the Muon Cooling Demonstrator programme is the construction of a test facility for 3 GHz RF cavities, to test the RF breakdown limit in a 7 T background field. The field is generated by a split-solenoid of 250...

Muon final cooling requires low-frequency RF cavities to satisfy beam-dynamics constraints, but conventional cavity dimensions increase rapidly as the operating frequency decreases. This work investigates compact RF cavity concepts for final cooling, focusing on reentrant geometries and dielectric loading using alumina and water. CST simulations were performed from 100 MHz down to 3 MHz,...

Wear of the container is a key engineering issue for potential dense granular targets in accelerator facilities. New understanding of the erosive mechanisms particular to dense media and their implications for a target will enable the robust design of a granular target for the Muon Collider.

Laser-assisted Hโป charge-exchange injection is a promising alternative to conventional carbon-foil stripping for high-power proton rings. In foil-based systems, foil heating and degradation, uncontrolled beam losses, and radioactivation limit the achievable average beam power. In this work, we evaluate the feasibility of laser-assisted Hโป charge-exchange injection into the accumulator of a...

This study uses FLUKA simulations to investigate pion production from proton interactions with a graphite target for muon collider applications. A 40 cm target is struck with 0.8 GeV and 8 GeV/c proton beams, and pion yields are evaluated in terms of angular and energy distributions. The dependence of pion yield on target length is also examined, showing saturation near one interaction length...

Efficient identification of heavy flavoured jets is essential for the physics programme of a future muon collider, particularly for Higgs and electroweak measurements where final states involving $b$-quarks dominate.

The beam cooling process constitutes a major challenge for the Future Muon Collider, as the beam is initially generated with a large phase-space volume that must be substantially reduced prior to acceleration. This reduction must be achieved on a timescale significantly shorter than the muon lifetime. In the low-energy regime, collective effects such as space charge and intrabeam scattering...

A future 10 TeV Muon Collider provides exciting opportunities to search for heavy long-lived particles (LLPs), but beam-induced backgrounds (BIB) from muon decays present a major challenge for detector performance and the reconstruction of these signatures. Previous detector studies have imposed standard hit-timing requirements to reduce BIB occupancy. However, such selections are optimized...

The current concept of the final cooling segment of the Muon Collider requires a set of fourteen 40 Tesla solenoids with a free bore of 50 [mm] to reduce the transverse emittance of the beam. These solenoids are intended to be made of REBCO (rare-earth barium copper oxide), a high temperature superconductor (HTS). The solenoid is constructed as a stack of pancakes, all winded with a 12 [mm]...

It is known that the addition of a static magnetic field has a degrading effect on the performance of RF cavities, a situation presenting particular problems for the cooling channel of a muon collider. Within this environment, a strong external magnetic field (2โ5 T) is superimposed upon the RF field in order to provide beam focusing. The RF field for such systems is required to be in the...

Developing a 6-D ionization cooling demonstrator is a top priority for muon collider development. Alongside experiments both upstream and downstream to demonstrate the necessary reduction in emittance for a collider, non-destructive measurements along the beamline of the bunch profile within 1mm and energy within 1% are necessary to tune components of the lattice. A muon ionization cooling...

Muon colliders require rapid six-dimensional cooling to reduce the large initial muon beam phase space before decay. In this work, we study a tilted-solenoid ionization cooling channel using G4Beamline, investigating whether solenoid tilts can generate transverseโlongitudinal coupling for emittance exchange while maintaining strong cooling and transmission.

We present lattice designs for a rapid cycling synchrotron (RCS) chain for a 10 TeV parton center-of-momentum (pCM) muon collider sited at Fermilab. A conventional RCS relies on only iron dominated, ramped field magnets that track beam momentum. To overcome the limited maximum fields of these ramped magnets, superconducting, fixed field magnets can be interleaved with the ramped field...

The final cooling stage of the Muon Collider concept relies on ultra-high-field solenoids exceeding 40 T, magnetic fields that can only be realised with high-temperature superconductors (HTS). The need for compact, cost-efficient magnets necessitates extremely compact winding packs, driving the overall operating current densities to 700 A/mmยฒ and beyond.

A future 10 TeV muon collider offers numerous exciting physics opportunities, the success of which depends on the ability to reconstruct charged particle trajectories, or tracks.
