How do scintillator detectors work
WebX-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays.. Detectors can be divided into two major categories: imaging detectors (such as photographic plates … WebFeb 26, 2024 · The scintillating material or phosphor produces a tiny light flash when a charged particle strikes it. The photomultiplier tube detects the light flash and produces an electric pulse. Amplifiers and electronic circuits record and count the electrical pulses from the photomultiplier tube.
