英文摘要: DAMPE is a space-based mission designed as a high energy particle detector measuring cosmic-rays and gamma-rays which was successfully launched on Dec.17, 2015. The BGO electromagnetic calorimeter is one of the key sub detectors of DAMPE for energy measurement of electromagnetic showers produced by e(+/-)/gamma. Due to energy loss in dead material and energy leakage outside the calorimeter, the deposited energy in BGO underestimates the primary energy of incident e(+/-)/gamma In this paper, based on detailed MC simulations, a parameterized energy correction method using the lateral and longitudinal information of electromagnetic showers has been studied and verified with data of electron beam test at CERN. The measurements of energy linearity and resolution are significant improved by applying this correction method for electromagnetic showers.
