Description
CSES-01 (China Seismo-Electromagnetic Satellite) is a multi-instrumental space mission developed by CNSA (Chinese National Space Administration) and ASI (Italian Space Agency) to investigate the near-Earth electromagnetic, plasma, and particle environment, focusing on the perturbations induced by natural sources and anthropocentric emitters. The Italian High-Energy Particle Detector (HEPD-01) onboard CSES-01, made of two planes of silicon tracker and a calorimeter of plastic scintillators and LYSO inorganic crystals, provides precise measurements for electrons of 3-100 MeV, protons of 30-200 MeV, and light nuclei. The good capabilities in the detection of particles, combined with a very large detector acceptance and with the CSES-01 polar orbit, make HEPD-01 well suited for many different purposes. These include measurements of the primary cosmic ray spectra, the trapped proton spectra inside the South Atlantic Anomaly, and the re-entrant albedo all-electrons fluxes. In this work, we present the data-analysis techniques and the different approaches used to provide measurements of the different particle populations detected along the CSES-01 orbits. Some of the recent HEPD-01 results are presented and compared with models, as the NASA AP9, which provides predictions of high-energy proton spectra in the radiation belts, or the HelMod model, used to simulate the solar modulation effects of cosmic rays in the heliosphere.
