Abstract :
The radiation hardness of prototype CsI(Tl) crystals has been tested for the electromagnetic calorimeter for the BESIII detector of the BEPCII. Although samples made by one of the producers were found to be soft under irradiation, the problem was quickly improved when this information was fed back. All the tested crystals were found to meet our requirement. At the same time, the monitor function of LED-Fiber system of BESIII EMC was verified.
