The China Seismo-Electromagnetic Satellite (CSES) space mission foresees a constellation of satellites devoted to the study of plasma, electromagnetic fields and particles perturbations potentially correlated with the occurrence of seismic events. Like the first satellite, launched in February 2018, CSES-02 hosts several payloads, among which the Italian High Energy Particle Detector (HEPD-02), with major improvements with respect to the first one. Key upgrades include the Control & Housekeeping system, with increased detector configurability and active monitoring, the advanced Trigger system, providing trigger prescaling and concurrent trigger configurations, and gamma rays detection capabilities in the 2–20 MeV range.
HEPD-02, after a large test campaign for the space qualification and calibration, has been installed on satellite with the other payloads and has currently undergone the tests at satellite level before launch, foreseen for 2025. In this contribution the instrument, with its improved design, and the test campaign are described.
