8 Mar 2017 | | Abstract: | 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 $e^{pm}/{gamma}$. Due to energy loss in dead material and energy
leakage outside the calorimeter, the deposited energy in BGO underestimates the
primary energy of incident $e^{pm}/{gamma}$. 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. | | Source: | arXiv, 1703.2821 | | Services: | Forum | Review | PDF | Favorites | |
