Description
The Circular Electron Positron Collider (CEPC) is a large international scientific facility proposed by the Chinese particle physics community. The proposal of silicon photomultiplier (SiPM) coupling with the glass scintillator as the detection unit HCAL is a new solution for the next generation calorimeter. In order to achieve the goal of high density and high light yield of the glasses. Glass Scintillators R&D; Group has prepared and researched a large number of scintillating glasses. Among them, the highest light yield can reach 1600 photons/MeV, and the best energy resolution is 19.64%@662keV.Further improvements in light yield and exploration of high-density glass systems are the next phase of the plan.
Summary
A large number of scintillation glasses were prepared and their scintillation properties were studied for HCAL of CEPC. The highest light yield of the glasses can reach 1600 photons/MeV. Glass Scintillators R&D Group will continue to improve the light yield and density of the scintillating glasses.
