Description
The High-Energy Particle Detector 01 (HEPD-01) is one of the payloads on board the China Seismo-Electromagnetic Satellite (CSES-01). CSES-01 was the first multi-channel space observatory of a series of planned missions devoted to monitoring perturbations in electromagnetic fields, plasma and charged particle fluxes induced by natural sources and artificial emitters in near-Earth space. It was launched in February 2018 into a Sun-Synchronous orbit at an altitude of about 500 km. The second satellite, CSES-02, will host a new optimized particle detector, HEPD-02, and is scheduled for launch in June 2025.
HEPD-01 was optimized to detect charged particles, electrons (3-100 MeV), protons (30-300 MeV), and light nuclei (up to a few hundreds of MeV) with high energy resolution and wide angular acceptance. It has provided new measurements on different research fields; in this contribution the latest scientific results obtained with the HEPD-01 detector will be presented, focusing on the measurements of the cosmic rays spectrum and its modulation. These results provide crucial new information for the physical models of the transport and diffusion of cosmic rays and, together with the measurements in the South Atlantic Anomaly, will give new insight in the Earth's magnetosphere modeling, which will be further improved by the next HEPD-02 experiment.
