英文摘要: Dark Matter Particle Explorer (DAMPE) is one of the first scientific exploration satellites of China, aiming to search dark matter by measuring the spectrum of electron/positron and gamma ray. DAMPE mainly consists of four sub-detectors including Plastic Scintillator Detector (PSD), Silicon Tungsten Tracker (STK), BGO Calorimeter (BGO) and Neutron Detector (NUD). As the most important sub-detector of DAMPE, BGO calorimeter plays a key role in precisely measuring energy of the incident cosmic ray and identifying particles. In this paper, thermal design of the calorimeter is introduced. Based on this design, the Finite Element Analysis (FEA) on temperature field of the BGO calorimeter is performed with the given on-orbit conditions. In the end, Thermal Vacuum (TV) test has been carried out in March, 2015 to prove the FEA is correct and the methodology in this paper is effective.
