摘要
Inorganic scintillation crystals have many advantages such as high light output,irradiation resistant,high detection efficiency,etc.The scintillator has more and more widely applications,it converts the deposition energy of high-energy radiation(X-rays,gamma rays,etc.)or high-energy particles(such as protons,neutrons and electrons)into ultraviolet or visible light.There are many kinds of scintillators,which can be divided into inorganic scintillators and organic scintillators based on chemical composition.Inorganic scintillator detector is one of the most widely used scintillator detectors.CsI crystals as one of inorganic scintillatior was widely used in the fields of nuclear physics experiments,safety inspection[1],oil exploration,and industrial detection,and so on,because of the high detection efficiency of rays and X-rays.
