The invention discloses a super-wide LET (Linear Energy Transfer) detection method and device capable of adopting a pixel type silicon sensor. The super-wide LET detection device based on the pixel type silicon sensor adopts two layers of pixel type silicon sensors to replace multiple layers of Si-pin sensors, and adopts a priority reading circuit to collect position, time and deposition energy information during triggering; while a high sampling rate is guaranteed, the incidence direction of each incidence charged particle can be recorded in real time so as to realize accurate target detection by an LET spectrum; and meanwhile, a plurality of [Delta]E telescope systems are simultaneously adopted to be used in parallel to realize wide LET spectrum detection by a coupling way. The device has the beneficial effects that the incidence direction and the ionization energy loss of each incidence charged particle can be recorded in real time, LET spectrum detection accuracy is greatly improved, the size of a detector can be effectively reduced, and the field of view of the detector is improved.
