Radiation effects in the space environment is of particular concern to electronics, often causing them to fail either due to ionization or from particles directly damaging components through collision. The goal of the partnership is to study the radiation effects of commercial off-the-shelf (COTS) components such as solid-state drives (SSDs) and digital-to-analog converters (DAC) to evaluate their performance for use in space instrumentation where high reliability is required. Space radiation effects on electronics are primarily mitigated by using radiation-hardened components. These components are designed using a variety of techniques including changing the manufacturing materials and implementing redundant elements inside the device, which results in a more expensive part. Consumer-grade and automotive-grade COTS components utilize mass production methods to lower the costs. In addition, current commercial designs are generally more tolerant to TID effects due to the fabrication technologies and advanced device structures. Demonstrating suitable radiation performance in modern commercial electronics will open the door to higher performance devices when compared to traditional radiation-hardened devices based on older technology. This research project will use the Co60 radiation chambers at the University of Saskatchewan and TRIUMF radiation test facility to screen variety of commercial electronics. The low dose rate Co-60 chamber will provide the capability of evaluating the sensitivity to enhanced low dose rate effects, and the proton beams at TRIUMF will be used to evaluate the single event effects of the components. The validated COTS components and the low-cost screening strategies will provide Xiphos with its most significant opportunity to reduce the cost of next-generation avionics used in low Earth orbit by several orders of magnitude. This research project will enable Canadian aerospace companies like Xiphos to reduce the cost of their avionics units by shifting from space grade parts to automotive grade parts without suffering a substantive reduction in reliability or longevity.

空间环境中的辐射效应特别关注电子设备，通常导致它们由于电离或颗粒而导致的失败，或者由于粒子直接通过碰撞损害组件而失败。合作伙伴关系的目的是研究商业现成（COTS）组件（例如固态驱动器（SSD）和数字到Analog转换器（DAC））的辐射效应，以评估其在需要高可靠性的空间仪器中使用的性能。通过使用辐射硬化的成分，主要减轻对电子设备的空间辐射影响。这些组件是使用各种技术设计的，包括更改制造材料并在设备内实现冗余元素，从而导致更昂贵的部分。消费级和汽车级的COTS组件利用质量生产方法来降低成本。此外，由于制造技术和高级设备结构，当前的商业设计通常更容易耐TID效应。与基于旧技术的传统辐射设备相比，现代商业电子产品中适当的辐射性能将为更高性能设备打开门。该研究项目将使用萨斯喀彻温大学和TriumF辐射测试设施的CO60辐射室来筛选各种商业电子产品。低剂量速率CO-60腔室将提供评估对增强低剂量速率效应的敏感性的能力，并且TriumF的质子束将用于评估组件的单个事件效应。经过验证的COTS组件和低成本筛选策略将为Xiphos提供其最重要的机会，以将低地球轨道中下一代航空电子产品的成本降低几个数量级。该研究项目将使像Xiphos这样的加拿大航空航天公司通过从空间级零件转移到汽车级零件，而不会大大降低可靠性或寿命，从而使加拿大航空航天公司能够降低其航空电子设备的成本。
