Abstract

In this paper, we design a structure of CsI(Tl) thin film crystal cell, and cover the CsI(Tl) thin film on the surface of the CCD directly. In order to prevent the photons emit from the surface of film, which result in depressing the fluorescence efficient, we cover the film with alumina to form reflective layer. Al layer is used to separate the CsI(Tl) crystal according to the size of CCD photosensitive cell, which solve problem that fluorescence cross talk between the different photosensitive cell. The fluorescence transmission efficiency of CsI(Tl) film crystal cell model is also researched , the results show the fluorescence transmission efficiency is maximum when the thickness of film is 40 μm.
