technical field [0001] The invention relates to the technical field of space radiation environment detection, in particular to a miniaturized space proton detector with a wide range and a detection method. Background technique [0002] The space radiation environment is the main factor affecting the safe operation of spacecraft in orbit, and the accurate detection of the space radiation environment is also the premise of space situational awareness and space weather forecast. The space radiation environment mainly includes protons, electrons and heavy ions, among which the protons are mainly distributed in the inner radiation belt of the earth, and the energy is mainly in the large dynamic range of 50KeV-150MeV. The existence of these particles will bring radiation hazards such as total ionizing dose and single event effect to spacecraft and satellites, and seriously affect the on-orbit performance and safe operation of spacecraft. Accurate detection of space radiation part...
