Abstract

An analysis of the impact of high-energy cosmic radiation protons on the onboard electronics of the spacecraft was performed. It has been shown that protons can cause nuclear reactions with the atomic nuclei of electronics material. Residual nuclei formed as a result of a nuclear reaction have sufficiently high energy to cross the sensitive areas of several bits of electronics, and the high ionizing ability of nuclear fragments makes it possible to generate an excess charge of carriers that exceeds the critical charge for upsets to occur simultaneously in several bits of an electronic device.

单个宇宙辐射粒子对机载航天器电子设备的多位扰乱
摘要 对高能宇宙辐射质子对航天器机载电子设备的影响进行了分析。结果表明,质子可与电子材料的原子核发生核反应。核反应形成的残余原子核具有足够高的能量,可以穿过多个电子器件的敏感区域,核碎片的高电离能力使其有可能产生过量载流子电荷,超过临界电荷,使电子器件的多个位同时发生损坏。
