Description
MAIA (Muon Accelerator Instrumented Apparatus) is a detector concept optimized for 10 TeV muon collisions, where the continuous decay of the circulating muons produces an intense beam-induced background (BIB) that shapes every aspect of the detector design. MAIA features an all-silicon tracker with precision timing inside a 5 T solenoid, surrounded by high-granularity silicon-tungsten and iron-scintillator calorimeters to facilitate particle-flow reconstruction. This talk will present the updated MAIA design and the full-simulation performance results from the recently released MAIA paper (arXiv:2502.00181). Even in the presence of challenging machine backgrounds, reconstruction efficiencies exceed approximately 95% for energetic tracks, photons, and charged pions in the central region of the detector. We will describe the multi-layered approach to detector design and object reconstruction that makes this possible, including shielding nozzles, timing and threshold selections, and background-aware reconstruction.
