Abstract：
This paper presents the measurement on the light output non uniformity of full size PbWO₄ crystal, which will be used in the electromagnetic calorimeter (ECAL) of CMS detector. It makes use of the ²²Na radiactive source and the coincident method. With the help of convolution fitting method, it is possible to make fine measurement on the light output non uniformity of the crystal. The effect of depolishing one of the lateral faces of the crystal on the non-uniformity has been studied. The slope of the non uniformity curve decreases with the increasing of the roughness. When the roughness reaches R_z=(1.49±0.27)μm the non uniformity curve meets the requirement of CMS ECAL.
