Description
The DArk Matter Particle Explorer (DAMPE) experiment began its on-orbit
operations on December 17, 2015. The main goal of DAMPE is the detection of
cosmic rays and gammas from the GeV to the TeV energy region to search for
dark matter and understanding the origin of the cosmic rays. The BGO
Electromagnetic Calorimeter (BGO ECAL) of the DAMPE is a total absorption
calorimeter that allows for a precise three-dimensional imaging of the
shower shape. It provides a good energy resolution (<1%@200GeV) and high
electron/hadron discrimination (>105). With the data set acquired during the
first and a half years of operation in space, a precise time-dependent
calibration for energy, shower topologies measured by the BGO calorimeter
had been developed. The first result of high energy electron/positron
spectrum which directly measured in space by DAMPE also will be presented.
