Component for radiation detector and radiation detector

摘要

A group of scintillator elements that convert an incident radiation into a light is one-dimensionally arranged. A photodiode array includes a group of photodiode elements that are arranged corresponding to arrangement positions of the respective scintillator elements, with detection surfaces formed substantially parallel to the incidence direction of the radiation. A reflection thin film is formed on a rear surface of the photodiode array in such a manner that the reflection thin film covers surfaces of the scintillator elements of the scintillator array that is fixed adjacent to the photodiode array.
