Description
Abstract: Lepton colliders, such as FCC-ee and a multi-TeV muon collider, have been proposed as possible options to investigate the Standard Model (SM) after the HL-LHC. In this context, calorimeters at future experimental facilities will require excellent energy resolution to effectively differentiate between hadronic decays of W and Z bosons, good granularity at the $O(1\ \mathrm{cm}^2)$ level, and excellent time resolution of a few nanoseconds, to be compliant with Particle Flow Algorithms that allow achieving optimal jet reconstruction performance.
We propose a hadronic calorimeter (HCAL) consisting of a sampling structure of absorber material and resistive Micro-Pattern Gaseous Detectors (MPGD) as the active layers.
In this contribution the latest developments in the project will be presented, including simulation studies using GEANT4 and recent results from test beam campaigns, focusing on the performance of the MPGD active layers and the hadronic-shower response of a 12 layers MPGD-HCAL prototype, where first 8-layers are of the dimensions of $20 \times 20\ \text{cm}^2$ and last the 4-layers of $50 \times 50\ \text{cm}^2$.
