The fluorescence transformation efficiency research of the hexagonal microcrystalline column model of CsI(Tl) film

Abstract

Based on the luminescence of the X-ray in the scintillator, this article builds a new hexagonal microcolumn model of CsI(Tl) thin film coupled with the charge-coupled device (CCD). The study proposes a fluorescence transport structure for X-ray luminescence and investigates the fluorescence transformation efficiency of the CsI(Tl) crystal to X-ray. Simulation results reveal that the different thickness and crystal column diameter has a significant impact on the fluorescence transmittance efficiency. The comprehensive discussion indicates that the maximum efficiency can be acquired under an appropriate grain diameter and film thickness.
