Description
A Muon Collider with the centre-of-mass energy of 10 TeV is actively studied as a successor of the LHC thanks to its unique combination of high energy reach, clean final state and low environmental footprint. Very low level of synchrotron radiation allows to accelerate muons to multi-TeV energies in a compact ring with minimal energy losses, allowing to reach the discovery potential of the FCC-hh at a fraction of the cost. Yet the decaying muons create extremely intense beam-induced background consisting primarily of soft electrons and photons. Impact of this background is highest in close vicinity to the interaction region, reaching 1000 hits/cm^2 in the innermost layers of the tracking detector.
In our detailed full-simulation studies we have identified key aspects of the tracking-detector design necessary to achieve the target physics performance, which include low material budget, high granularity and high timing resolution at the level of tens of picoseconds.
This contribution will introduce the main technical aspects of the Muon Collider, focusing on the implications of the beam-induced background for the design and performance of the tracking detector. The two flagship technologies considered in our detector design will be discussed: DC-RSD and DMAPS, including the key areas of further R&D necessary to make these technologies suitable for the Muon Collider environment.
