Description
The CSES mission, coordinated by China National Space Administration (CNSA) and Italian Space Agency (ASI), aims to probe the near-Earth environment through coordinated electromagnetic, ionospheric, magnetospheric, and cosmic-ray observations.
The High-Energy Particle Detector 02 (HEPD-02) was developed by the Italian Limadou collaboration for the CSES-02 satellite, launched in June 2025., HEPD-02 measures electron fluxes from 3 to –100 MeV and proton fluxes from 30 to –200 MeV. Building on the experience of HEPD-01 experiment, operating aboard CSES-01 since February 2018, HEPD-02 features a redesigned tracker with monolithic active pixel sensors (MAPS) that achieves <10° angular resolution forat 103 MeV electrons and aimproved new trigger and calorimeter detectors made of plastic and crystal scintillator layers read-out by PMTs optimized to contain electrons up to 100 MeV. As one of the few instruments currently in orbit dedicated to this energy range, HEPD-02—like its predecessor— is expected to deliver measurements that will significantly advance our understanding of the radiation environment around the Earth. This presentation reports the technological solutions and in-flight performances of the HEPD-02 instrument.’s in-flight performance and outlines the scientific return anticipated over a ≥6-year mission spanning the current solar maximum and the subsequent declining phase of solar activity.
