Description
This contribution highlights recent progress in developing innovative Micromegas detectors for future collider experiments, aimed at precision tracking and muon systems, with a particular focus on scalability and robust performance. The core technology is based on single-stage pixelized resistive Micromegas detectors, featuring resistive spark-protection layouts implemented through different schemes and integration strategies, optimized for various operating conditions.
Results for these detectors in the high-rate configuration show that efficient operation up to 10 MHz/cm2 can be achieved, with excellent spatial resolution (below 100 μm) and good timing resolution (about 5 ns). This performance is made possible by fast charge evacuation and pad-based readout with mm2 scale granularity. It is worth highlighting that the concept has been realised in large-area prototypes, demonstrating its scalability towards the employment in future collider experiments.
Building on these achievements, low- and medium-rate versions targeting applications for muon systems at FCC-ee have been developed, aiming at simplifying the design and reducing the number of readout channels, while still preserving the key functional and performance characteristics of the high-rate version. This has been realized through the implementation of the charge-sharing technique, which can drastically reduce the readout channel count while maintaining adequate spatial precision.
Comprehensive results will be presented from measurements on large-area modules and on detectors employing different capacitive-sharing configurations.
