A theoretical model of multi-energy radiography is proposed and two approaches—“synthesis” and “analysis”—to studying the structure of objects by this method are considered. It is theoretically… Continue Reading
A direct method is proposed for reconstruction of the effective atomic number by means of multi-energy radiography of the material. The accuracy of the method is up to 95%. Advantages over… Continue Reading
Multi-energy radiography is a new direction in non-destructive testing. Its specific feature is separate detection of penetrating radiation in several energy channels. Multi-energy radiography allows… Continue Reading
Abstract Detectors of the scintillator-photodiode type were obtained on the basis of CsI(Tl), CdWO 4 and ZnSe(Te) crystals, and their comparative study was carried out, aiming at their use in X-ray… Continue Reading
Abstract Effects of the intrinsic and dopant-induced defects in cadmium tungstate (CWO) crystals upon their luminescence and functional characteristics have been studied. It has been shown that… Continue Reading
Abstract Results of experimental studies of detector arrays scintillator-photodiode (S-PD) and scintillator-photoreceiving device (S-PRD) used for X-ray digital radiography have shown that there… Continue Reading
Abstract A low background scintillation spectrometer based on CdWO 4 crystals of large volume (100–200 cm 3 ) with improved energy resolution has been developed as a result of advances in crystal… Continue Reading
Abstract The dual-energy computer tomography (CT), as compared with its traditional single-energy scanners, ensures substantially higher contrast sensitivity. This allows efficient separate… Continue Reading
For reconstruction of the spatial structure of many-component objects, it is proposed to use multi-radiography with detection of X-ray by combined detector arrays using detectors of… Continue Reading
This work has been aimed at measuring the absolute light yield of scintillators CsI(Tl), CWO, GSO and BGO of different size in photons/MeV, using the PMT internal resolution method.
