Abstract: A gamma ray detector is a detector detecting gamma rays and includes a photomultiplier tube having an entrance window and a photoelectric surface. The entrance window is a Cherenkov radiator. The photoelectric surface is formed on a vacuum side of the entrance window via an intermediate layer. The thickness of the intermediate layer is equal to or less than the wavelength of Cherenkov light emitted by an interaction of the gamma rays with the entrance window.
