【 摘 要 】

The BESIII experiment is located at the Beijing Electron Positron Collider (BEPCII) in China. Its electromagnetic calorimeter (EMC) consists of 6240 CsI(TI) crystals, each read out by two Photodiodes (PD) at the end of the crystal. Changes in the response of the calorimeter due to radiation damage in the crystals or changes in the photo detector output are monitored with a light pulser system.
