Dark Matter Particle Explorer (DAMPE)
The DArk Matter Particle Explorer (DAMPE), also known as "Wukong" in China, It was successfully launched into a Sun-synchrotrons orbit at an altitude of about 500 km on 17 December, 2015. Its total mass is 1850 kg and was designed to operate for at least three years.
DAMPE is a high-energy particle detector optimized for studies of CREs and γ –rays up to about 10 TeV, which can measure the GeV-TeV cosmic ray electrons (including positrons) and gamma-rays with unprecedentedly high energy resolution. It can also measure nuclei to about 100 TeV per nucleon (Chang et al. 2017).Currently, DAMPE has been in orbit for 7 years and is still in the long routine operation phase.
The DAMPE instrument, from top to bottom, consists of a plastic scintillator detector（PSD）, a silicon–tungsten tracker-converter detector（STK）, a bismuth germanium oxide (BGO) imaging calorimeter, and a neutron detector（NUD）.
