The importance and the feasibility to extend the proton measurements up to hundreds of MeV is evaluated. The a-Si:H presents an excellent radiation hardness and finds application in harsh radiation environments for medical purposes, for particle beam characterization and, as we propose here, for space weather science applications. The critical flux detection limits for X rays, electrons and protons are discussed.Astronomy & Astrophysicsspace weathersolar energetic particle eventshydrogenated amorphous siliconsolar activitypeak intensitiessolardependencestereotext::journal::journal article::research article
