Single Event Effects in Ground Level Infrastructure

目标已在前一节中说明，并在支持案例中进一步阐述。对项目合作伙伴的影响将是提高对地面单一事件影响现象和ESW事件风险的理解。迄今为止，这个主题主要集中在静止的背景星系宇宙射线环境上，很少关注空间天气事件期间的增强。通过审查这些事件的可能性和潜在影响，该项目将提高合作伙伴组织对这一主题的认识，并在适当的时候提高他们所经营的更广泛行业的认识。主要结果将是对ESW事件期间地面电子系统对SEE的脆弱性进行风险评估。将计算SEE率和故障概率，并用于确定需要何种（如果有的话）缓解协议来降低风险。行业合作伙伴将能够使用各种方法减少系统的脆弱性，包括根据弹性标准改进电子元件的采购，并通过系统设计提高故障容忍度。研究结果也可用于评估对现有系统改造恢复力措施的必要性，尽管这仅是合作伙伴的考虑，项目不会在这方面提出单方面的建议。

Objectives are stated in the previous section and are further elaborated in the Case for Support. The impact on project partners will be an improved understanding of the phenomenon of single event effects at ground level and the risk from an ESW event. This topic has hitherto focused on the quiescent background galactic cosmic ray environment, with very little attention paid to enhancements during space weather events. By reviewing the likelihood and potential impact of these events, the project will raise awareness of the topic within the partner organisations and, in due course, within the wider industries in which they operate. The main outcome will be a risk assessment of the vulnerability of ground-level electronic systems to SEE during an ESW event. SEE rates and failure probabilities will be calculated and used to determine what (if any) mitigation protocols are required to reduce the risk. Industry partners will be able to reduce the vulnerability of their systems using a variety of methods, including improving their procurement of electronic components based on resilience criteria and increasing failure tolerance through system design. The results may also be used to evaluate the need for retrofitting resilience measures to existing systems, though this is a consideration for the partners alone and the project will not make unilateral recommendations in this regard.
