WebScintillation (physics) Scintillation is the physical process where a material, called a scintillator, emits UV or visible light under excitation from high energy photons ( X-rays or γ-rays) or energetic particles (such as electrons, alpha particles, neutrons or ions ). [1] [2] See scintillator and scintillation counter for practical applications. WebA good linearity of the LAAPD response to X-rays was observed up to energies of about 20keV. The ratio of the APD gain for X-rays and light pulses remained constant (within 1%) for both the 5.9 and 16.6keV photopeaks in the APD gain range up to 100. This allowed for use of soft X-rays as an accurate reference in APD scintillation detection study. 5s定着化研修 https://tambortiz.com
