Description
Since 2010 the electromagnetic endcap calorimeter based on BGO crystals is taking part in experiments as one of the system of CMD-3 detector. The spacial resolution is one of crucial parameters of the calorimeter. The inaccurate knowledge of real calorimeter position can limit the resolution.
In this work the alignment of the center of the calorimeter with respect to the tracking system of the CMD-3 detector has been performed using events of two-quantium annihilation.
The alignment technique that has been used to determine the real position of the calorimeter is described. Finally, the improvement in spacial resolution of the calorimeter after application the correction on the real calorimeter position is shown.
