The μ-RWELL-based preshower and muon detectors of the IDEA detector concept

The IDEA detector, designed for future e+e- colliders like FCC-ee or CEPC, features an innovative design with a central tracker enclosed in a superconducting solenoidal magnet, a pre-shower system, and a dual readout calorimeter. Positioned within the iron yoke are three muon detector stations. The pre-shower and muon detector employ μ-RWELL technology, inheriting the best characteristics of GEM and Micromegas, being spark-robust and simple to assemble. Both preshower and muon detectors follow a modular design, with 50x50 cm2 μ-RWELL tiles. The preshower targets a 100 μm spatial resolution, while the muon detector prioritizes channel count. Vigorous R&D on μ-RWELL technology has yielded various prototypes characterized in lab and test beams, and technology transfer to industries for mass production.
