Abstract:Based on the software GEANT4,the description of the detector endcap electromagnetic calorimeter of Beijing spectrometer is accomplished.At the same time,the behaviors of electrons,photons and hadrons in endcap electromagnetic calorimeter (EEMC) are studied.Different behaviors such as energy/position resolutions under the standard electromagnetic interaction package are compared with the low electromagnetic interaction package,which will be helpful for particle discrimination. |
