Abstract：
In the process of design and research of BES Ⅲ crystal calorimeter, we made a detailed Monte Carlo study for the performance of BES Ⅲ CsI crystal calorimeter on the basis of the detection cell of 7×7 CsI matrix. Results are presented on incoherent noise, on energy linearity, on uniformity of the crystal light output, on position dependence. Those results show that the energy resolution of the 5×5 matrix sum is about 2.1% for 1 GeV photon and the best energy resolution of the lower energy photon is obtained with the energy threshold of 2.5 σ_noise. The energy deposit in the matrix decreases by about 1% and the energy resolution degrades by about 0.3% when 800MeV photons are injected in the gap region between two crystals. The average position resolution is about 6.3 mm at 800 MeV.
