Calibration of the FY-3E particle sensors: High-Energy Particle Detector (HEPD)

Abstract The FY-3 satellites are China's second generation polar-orbiting meteorological satellites. high-energy particle detector (HEPD) suite of measures protons and electrons in different energy ranges. As the fifth satellite series, FY-3E continues to observe electrons. Here, we use Monte Carlo simulations based on GEANT4 code model electron calibrate electron/proton campaigns at Space Electron Facility, National Science Center (NSSC-SEF) 100 MeV high intensity proton cyclotron China Institute Atomic Energy (CYCIAE-100). Due limitation accelerator, electronic calibration results also provided. Overall, findings this study can serve as a useful reference for characterizing performance HEPD verifying feasibility on-orbit data.
