In order to understand the escape of the Martian atmosphere, study the interaction between the solar wind and the Martian atmosphere, and research the acceleration mechanism of neutral particles near the Martian shock, the characteristics of particles in Mars plasma will be explored. A Mars ion and neutral particle analyzer prototype having three functions: Energy analysis, direction analysis and composition analysis, has been developed. A mass spectrometer using Time-of-Flight (TOF) structure based on ultra-thin carbon film, which can obtain a high resolution, has been used to implement composition analysis. Because temperature varies greatly on Mars, in order to distinguish TOF of different particles, the TOF system requires a time resolution of less than 600 ps within the temperature range of-40℃ to +60℃. In this paper, a prototype electronics mainly including a time-to-digital converter (TDC) implemented in Field Programmable Gate Array (FPGA) for mass spectrometer is described. For anti-irradiation considerations, the TDC architecture is implemented in a flash FPGA, and adopted Triple Module Redundancy (TMR) to mitigate Single-Event-Upset (SEU). Online correction is adopted to ensure that TDC can work accurately in the large temperature range. Rom-temperature's test results show that a time resolution of 539ps with a 239 ps RMS was obtained. Thermal tests suggested that the prototype electronics operates well in a temperature range from-40℃ to +60℃ with an RMS less than 305.5 ps.

“…Using CRÈME96 we have predicted that SEU probability for the DFFs in APA FPGA chips is about 6.8×10 -7 /(bit*day) in the DAMPE orbit [9], based on the assumption of the SEU threshold value of about 3 MeV*cm 2 /mg, and the SEL probability for VA160 is about 2.7×10 -5 /(device*day) for VA160 and 8.1×10 -5 /(device*day) for VATA160. We can roughly calculated out that the SEL probability is about 2×10 -5 /(day*device) for the 84 ASIC chips in total, and the SEU probability…”

The DAMPE (DArk Matter Particle Explorer) is a scientific satellite which was successfully launched in Dec., 2015, with the major scientific objective of indirect searching for the clue of dark matter particles in space. The BGO (Bismuth Germanate Oxide) calorimeter is a critical sub-detector of DAMPE payload, with the functions of measuring the energy of cosmic particles, distinguishing positrons/electrons and gamma rays from hadron background, and providing trigger information. It is composed of 308 BGO crystal bars and each bar is coupled by two Hamamatsu R5610A PMTs (photomultiplier tubes), from both sides respectively. Each PMT sends out three dynode signals, to achieve a large dynamic range, which results in 1848 signal channels. A readout electronics system, which consists of 16 FEE (Front End Electronics) modules, is designed to precisely measure the charges of PMT signals and to provide "hit" signals. The in orbit status of the electronics system is to be introduced in this paper.
