Сцинтиляційний детектор для рентгенівської радіографії

Abstract

Luminescent materials based on A2B6 compounds are among the most promising for X-ray radiography. The main advantages of crystals of this type are a high internal quantum yield of luminescence and wide possibilities for influencing the emission spectra and other initial characteristics of luminescent materials. To unambiguously determine the type of substance, the radiography system uses sequentially located low-energy and high-energy scintillation detectors, as well as a filter. In the case of low useful signal levels, it is important to have a minimum noise level of the detector crystal. For this, the noise characteristics of the sensitive element of the detector were optimized.
