The proposal to create a Muon Collider with Multi-TeV energy levels presents an unprecedented opportunity for advancing high energy physics research. With this collider, it will be possible to accurately measure the Higgs coupling with other Standard Model particles, as well as the trilinear and quadrilinear Higgs self-coupling. By doing so, researchers hope to gain a more precise understanding of the Higgs potential and potentially discover evidence of new physics beyond the Standard Model. However, one of the primary challenges for this project is dealing with the high background radiation caused by decaying muons in the beam. To address this, an innovative hadronic calorimeter has been designed that utilizes Micro Pattern Gas Detectors (MPGDs) as active layers. MPGDs are ideal for high radiation environments and offer high granularity for precise spatial measurements. The calorimeter has been optimized for jet reconstruction and background suppression, and its design and layout have been simulated using the Geant4 toolkit to support detector R&D. This article details the design and optimization of the MPGD-based hadronic calorimeter.
