The BGO calorimeter, which provides a wide measurement range of the primary cosmic ray spectrum, is a key sub-detector of Dark Matter Particle Explorer (DAMPE). The readout electronics of calorimeter consists of 16 pieces of Actel ProASIC Plus FLASH-based FPGA, of which the design-level flip-flops and embedded block RAMs are single event upset (SEU) sensitive in the harsh space environment.

Design of the Readout Electronics for the Qualification Model of DAMPE BGO Calorimeter
/ Feng, Changqing (Hefei, CUST) ; Zhang, Deliang (Hefei, CUST) ; Zhang, Junbin (Hefei, CUST) ; Gao, Shanshan (Hefei, CUST) ; Yang, Di (Hefei, CUST) ; Zhang, Yunlong (Hefei, CUST) ; Liu, Shubin (Hefei, CUST) ; An, Qi (Hefei, CUST)
The DAMPE (DArk Matter Particle Explorer) is a scientific satellite being developed in China, aimed at cosmic ray study, gamma ray astronomy, and searching for the clue of dark matter particles, with a planned mission period of more than 3 years and an orbit altitude of about 500 km. The BGO Calorimeter, which consists of 308 BGO (Bismuth Germanate Oxid) crystal bars, 616 PMTs (photomultiplier tubes) and 1848 dynode signals, has approximately 32 radiation lengths. [...]
