摘要
本文分析了在“风云一号(B)”气象卫星环境中各种粒子辐射在集成芯片临界体积中产生的能量沉积,即LET(线性能量传输);得到了银河宇宙线1≤Z≤28、银河宇宙线异常成分(C、N、O、Ne、Ar、Fe)、内辐射带质子等产生的LET,计算了其分别产生的单粒于事件(SEU)翻转率。
This paper analyses energy deposit in critical volumes of integrate chips, whi-ch produced by some radiated particles in Feng Yun-1 (B) satellite environment. That is called linear energy translation (LET). We have obtained the LET of Galactic Cosmic-Ray components 1 ≤Z≤28, Galactic Cosmic-Ray anomaly components (C, N, O, Ne, Ar, Fe), and inner radiation belt protons. And single event upset (SEU) ratioes produced by these particles are caculated respectively.
