The High-Energy Particle Detector (HEPD) onboard the China Seismo-Electromagnetic Satellite
(CSES-01) - launched in February 2018 - is a light and compact payload suitable for measuring
electrons (3-100 MeV), protons (30-300 MeV), and light nuclei (up to a few hundreds of MeV)
with a high energy resolution and a wide angular acceptance. The very good capabilities in particle
detection and separation, together with the Sun-synchronous orbit, make HEPD well suited for
galactic particles and solar modulation studies. We report here some insights on the data-analysis
techniques employed for this kind of study; as a result, semiannual galactic hydrogen differential
energy spectra between 40 and 250 MeV for the period between the end of the 24th and the start
of the 25th solar activity cycle, are presented . Moreover, a brief discussion on the comparison
with theoretical spectra obtained from the HelMod 2D Monte Carlo model is also presented.
