Wide-range miniaturized space proton detector and detection method

The invention relates to the technical field of space radiation environment detection, and particularly relates to a wide-range miniaturized space proton detector and a detection method. The wide-range miniaturized space proton detector comprises a low-energy detection area and a high-energy detection area, wherein the low-energy detection area is used for detecting and identifying medium-energy protons and is provided with a graphene film, a microchannel plate and a first detector; the high-energy detection area is used for detecting and identifying high-energy protons and is provided with asecond detector, a Ta energy reduction sheet and a third detector; and the first detector, the second detector, the Ta energy reduction sheet and the third detector are sequentially arranged from thinto thick. According to the invention, the medium-energy protons in a low-energy section are detected and identified through a method of the graphene film and a silicon semiconductor, and the high-energy protons in a high-ener
