    count noun Model A intended for use with solid scintillators
    Example sentencesExamples
    • It consists of a 13 meters in diameter weather balloon filled with about a kiloton of liquid scintillator, a chemical soup that emits flashes of light when an incoming anti-neutrino collides with a proton.
    • Plastic scintillators, placed between the bricks, are needed to produce a flash of light upon absorption of an ionizing particle, specifically, neutrino.
    1. 1.1 A detector for charged particles and gamma rays in which scintillations produced in a phosphor are detected and amplified by a photomultiplier, giving an electrical output signal.
      闪烁计数器;(闪烁计数器中的)闪烁体
      Example sentencesExamples
      • Luc activity was assayed quantitatively with a liquid scintillator using the photon-counting mode after the feeding of luciferin as substrate.
      • The technologies used for detection are different, however, as the MINOS detectors are made from steel plates layered with plastic scintillators.
      • Photons emitted from the scintillator generate an electron-hole pair.
      • The intensity and the energy of the ion beams on the target micropositioning stage or after the beam has penetrated the target are measured with a plastic scintillator.
      • However, traditional film-based scanners are gradually being replaced by digital systems that are based primarily on caesium-iodide scintillators coupled to flat-panel detectors.
