Description
Future electron-positron collider experiments impose stringent requirements on calorimeter systems, including high granularity (compatible with the particle flow approach), excellent energy resolution, low cost, and large-scale constructability. While existing calorimeter concepts each possess distinct merits, none can simultaneously satisfy all of the above criteria. Scintillating glass, as a novel scintillating material, offers several compelling advantages—tunable composition, feasibility of large-size fabrication, low cost, high density, and high light yield—making it a promising candidate for realizing a calorimeter design that meets all these requirements. For the AGORA framework, we propose a three-dimensional high-granularity scintillating glass calorimeter concept, comprising a homogeneous electromagnetic calorimeter (ECAL) and a high-sampling-ratio hadronic calorimeter (HCAL).
This report presents recent progress in the design and simulation of the scintillating glass calorimeter, including the optimization of the detector layout, granularity, sampling ratio, and number of layers. Based on the optimized design, a detailed detector description has been implemented in the simulation framework, accompanied by the development of a realistic digitization algorithm. Preliminary detector performance has been obtained from the full simulation chain. Furthermore, we investigate the impact of scintillating glass material properties on energy resolution and demonstrate how performance improvements can be achieved through dedicated detector design optimization.
