[CRD117] The On-orbit Performance of DAMPE Trigger System


  • Yang LIU

Primary authors



The Dark Matter Explorer (DAMPE) was launched into a sun-synchronous orbit at the altitude of 500 km on Dec 17, 2015. Its main scientific objective is to detect electrons and photons in the range of 5 GeV-10 TeV with a high energy resolution. A first investigation to the flight data shows that the trigger system operates quite well. The trigger system reduces the trigger rate on orbit from about 1 kHz to 70~100 Hz. This rate is properly high and will not bring pile-ups to the data acquisition system. The trigger efficiency for high energy electrons is almost 100%, which makes the detector very suitable for fulfilling its tasks.
