The Design and Realization of the Payload Integrated Test System for DAMPEtwo

The Dark Matter Particle Explorer (DAMPE) is a space-borne high-energy cosmic ray detector. The payload consists of five subsystems, including the Plastic Scintillator Detector (PSD), the Silicon-Tungsten tracKer converter detector (STK), the BGO (Bismuth Germanate) calorimeter, the NeUtron Detector (NUD), and the Data AcQuisition system (DAQ). The five subsystems work collaboratively to collect the information of cosmic rays. In order to systematically verify the performance of the payload before launching, we have developed a set of integrated test system for the ground tests of the payload based on the LabWindows/CVI (C programming language Virtual Instrument) platform. This system has realized the integrity and automation of the comprehensive ground tests of the payload, improved the security, reliability, and efficiency of the ground tests, and provided a guarantee for the successful delivery of the payload.
