Abstract
The Circular Electron Positron Collider (CEPC) project is a Higgs/Z factory proposed by Chinese high energy physics community. A fine granular scintillator-tungsten electromagnetic calorimeter (ScW ECAL) is under development for the application of the particle flow algorithm (PFA) at CEPC. The active layers of the ScW ECAL are consisting of 5 × 45 mm2 plastic scintillator strips, with silicon photomultiplier (SiPM) readout. A set of ScW ECAL geometries has been implemented into the Geant4 simulation to optimize the geometry parameters such as layer numbers and scintillator sensor thickness. The performances of SiPM and the scintillator strip detector were tested, and the test results indicate that the SiPM and the sensor detector worked well. These results are meaningful for the construction and the tests of the prototype at the next stage.
