WebPresently this technology is implemented using scintillation detectors consisting of a scintillation crystal, which produces optical photons when excited by a gamma ray, and a photomultiplier tube (PMT), which detects these photons. The detector must withstand the high vibrations and high temperatures present in down-hole applications. WebAug 28, 2015 · We fabricated a small-sized, flexible, and insertable fiber-optic radiation sensor (FORS) that is composed of a sensing probe, a plastic optical fiber (POF), a photomultiplier tube (PMT)-amplifier system, and a multichannel analyzer (MCA) to obtain the energy spectra of radioactive isotopes. As an inorganic scintillator for gamma-ray …
