Single event effect hardness for the front-end ASICs in the DAMPE satellite BGO calorimeter

Chinese Physics C 2016年第1期40卷 86-91页

The Dark Matter Particle Explorer （DAMPE） is a Chinese scientific satellite designed for cosmic ray studies with a primary scientific goal of indirect detection of dark matter particles. As a crucial sub-detector, the BGO calorimeter measures the energy spectrum of cosmic rays in the energy range from 5 GeV to 10 TeV. In order to implement high-density front-end electronics （FEE） with the ability to measure 1848 signals from 616 photomultiplier tubes on the strictly constrained satellite platform, two kinds of 32-channel front-end ASICs, VA160 and VATA160, are customized. However, a space mission period of more than 3 years makes single event effects （SEEs） become threats to reliability. In order to evaluate SEE sensitivities of these chips and verify the effectiveness of mitigation methods, a series of laser-induced and heavy ion-induced SEE tests were performed. Benefiting from the single event latch-up （SEL） protection circuit for power supply, the triple module redundancy （TMR） technology for the configuration registers and the optimized sequential design for the data acquisition process, 52 VA160 chips and 32 VATA160 chips have been applied in the flight model of the BGO calorimeter with radiation hardness assurance.

Science China(Information Sciences) 2022年第2期65卷 259-260页

作者： Chang CAI Bingxu NING Xue FAN Tianqi LIU Lingyun KE Gengsheng CHEN Jian YU Ze HE Liewei XU Jie LIU Institute of Modern Physics Chinese Academy of Sciences State Key Laboratory of ASIC and System Fudan University School of Nuclear Science and Technology University of Chinese Academy of Sciences The Fudan Microelectronics Group Fudan University School of Electronic Engineering and School of Microelectronics Chengdu Technological University

Dear editor,The static random-access memory (SRAM)-based field programmable gate arrays (FPGAs) mainly composed of extensive configurable logic blocks (CLBs),high-speed embedded memories (BRAMs),and a set of programmable routing,wires or switch boxes[1,2]are commonly used in avionic and space fields because of their advanced performance and high flexible in-field reprogramming abilities[2].However,the advanced SRAM-based FPGAs are susceptible to radiation effects,
