Numerical Optimization of 6D Cooling Solenoids for a Muon Collider / Fabbri, S (CERN) ; Bottura, L (CERN) ; Statera, M (LASA, Segrate)
In the current most evolved design concept of a machine for accelerating and colliding muons, there exists two long (∼1 km) channels for cooling newly created muons and antimuons. Termed the ‘6D cooling channels’, the beam is cooled in momentum and position space using a series of alternating polarity solenoids which create an oscillating field in the beam direction, absorbers and radio-frequency cavities.

In the framework of the IMCC (International Muon Collider Collaboration), a feasibility study for a collider ring 10 km long with muons having a center of mass energy of 10 TeV is currently being carried out. The superconducting magnets represent one of the most challenging components of the collider stage of such a facility: indeed, the need for high fields, large apertures and dipole + quadrupole combined function require technological choices at the edge of the status of the art.

Mechanical Design of a ReBCO Non/Metal-Insulated 40 T Solenoid for the Muon Collider / Accettura, C (CERN) ; Bertarelli, A (CERN) ; Bordini, B (CERN) ; Bottura, L (CERN) ; Dudarev, A (CERN) ; Kolehmainen, A (CERN) ; Mulder, T (CERN) ; Sanda, F (CERN) ; Vernassa, G (CERN)
In the framework of the design studies of a Muon Collider (MuC), the design of Ultra-High-Field (UHF) magnets is a crucial part, particularly for the MuC's final cooling stage. To address this, CERN has recently introduced a conceptual design for a 40 T solenoid characterized by very compact pancake coils. [...]

In accordance with the guidelines set forth in the Updated European Strategy for Particle Physics, the International Muon Collider Collaboration has been initiated to assess the feasibility of a Muon Collider facility with a center-of-mass energy of 10 TeV. The primary challenges stem from the brief muon lifetime at rest, which is limited to 2.2 µs. [...]

Research and Development Status for an Innovative Crystal Calorimeter for the Future Muon Collider / Cantone, C (Frascati) ; Ceravolo, S (Frascati) ; Colao, F (ENEA, Frascati) ; Meco, E Di (Frascati) ; Diociaiuti, E (Frascati) ; Frank, I (Munich U. ; CERN) ; Gianotti, P (Frascati) ; Gargiulo, R (INFN, Rome ; Rome U.) ; Leonardi, E (CERN ; UC, Riverside) ; Lucchesi, D (INFN, Padua) et al.
Accurate measurements of physical processes in high energy frontier experiments demand exceptional spatial, temporal, and energy precision to discern the physics behind high-energy particle jets. Calorimeters, like other detection systems, must be able to meet these increasingly challenging performance requirements. [...]

This work focuses on the design of resistive dipole accelerator magnets for the Muon Collider accelerator under study in the frame of the International Muon Collider Cooperation (IMCC) and with the participation of the European Union (MuCol program). The design specifications require that these dipoles are subjected to very fast ramps, with ramp times in the range from 1 ms to 10 ms. [...]

Conceptual Design of a Target and Capture Channel for a Muon Collider / Accettura, C (CERN) ; Bottura, L (CERN) ; Calviani, M (CERN) ; Calzolari, D (CERN) ; Ximenes, R Franqueira (CERN) ; Kolehmainen, A (CERN) ; Lechner, A (CERN) ; Gomez, J Lorenzo (Fusion for Energy, Barcelona) ; Portone, A (Fusion for Energy, Barcelona) ; Esteban, F J Saura (CERN) et al.
The “target and capture channel” is one of the crucial systems in a Muon Collider, whose function is to create an intense muon beam from the decay of the pions generated by a multi-MW proton beam impinging on a particle-producing target. To guarantee the capture of the pions and resulting muons, the channel consists of a sequence of solenoids, providing a well-defined profile on axis, with 20 T peak at the target location and an adiabatic decrease along the channel length.
