Properties uniformity studies for scintillation elements of 1D- and 2D-matrices on the basis of crystals ZnSe(Te), CdWO₄, CsI(Tl), Bi₃Ge₄O₁₂

摘要

Results are presented on parameters of light output and uniformity of scintillation properties of 1D and 2D-matrices for different conditions of their preparation. It has been shown that with grinded scintillators based onud ZnSe(Te) and CdWO₄ light output is higher as compared with the polished ones. Energy resolution and light outputud have been measured for 2D-scintillators on the basis of CdWO₄, CsI(Tl), ZnSe(Te) for γ-radiation and α-particlesud from ²³⁵Pu. Advantages of 2D-scintillators over monolithic scintillators are shown.
