Description
The experimental results at CERN's LHC confirmed the Standard Model with high precision. However, several questions are still open, and successors for the High-Luminosity LHCs are proposed to explore the Standard Model with unprecedented precision. Future colliders, like the FCC-ee and Muon Collider, aim to measure Higgs Yukawa couplings and self-interactions with unprecedented accuracy, requiring precise jet energy measurements and advanced calorimetry with Particle Flow algorithms.
In this context, we propose the development of a hadronic calorimeter based on resistive Micro Pattern Gas Detectors (MPGDs) for future colliders. MPGDs are a class of gaseous detectors that offer several advantages for calorimetry applications. They feature adaptable, high-granular readout capabilities, typically on the order of square centimeters or less; moreover, the radiation-hard technology and high rate capabilities of MPGDs, with the potential to handle rates up to 10 MHz/cm², make them particularly suitable for the challenging background conditions, such as the ones expected at the Muon Collider.
Furthermore, resistive MPGDs offer additional benefits that are crucial for high-performance calorimetry. The resistive layer incorporated in these detectors provides excellent spatial resolution, contributing to the operational stability of the detectors by effectively quenching discharges, thereby enhancing their reliability and longevity in high-rate environments.
A program of characterization studies has been undertaken to assess the performance of resistive MPGDs for hadronic calorimetry.
The results of the characterization studies, in terms of efficiency, spatial and time resolution, and response uniformity, performed with a muon beam at CERN SPS on three MPGD technologies, resistive MicroMegas, µ-RWELL, and RPWELL, are presented. Additionally, results for an HCAL cell prototype consisting of eight layers (~1 λ) of alternating stainless steel and MPGD detectors tested with pion beams of energy ranging up to 10 GeV are shown.
