随着对高性能和低成本的需求不断增长，商用现货（COTS）部件正在应用于许多空间应用。由于某些产品具有大量COTS设备，因此单独测试它们可能会变得成本高昂且复杂。质子测试提供了这样一种折衷方案。根据空间环境和应用，质子测试可以是评估部件的成本效益技术。本文介绍了质子与重离子测试之间的权衡考虑的优点和缺点。这样的情况下，讨论了使用商业视频控制器和CCD的低地球轨道系统，如国际空间站COTS正在大量考虑。建议了可能的风险缓解措施，以降低灾难性故障的可能性。
With the increasing demand for high performance and lower cost, commercial off-the-shelf (COTS) parts are being applied to many space applications. Because certain products have a large quantity of COTS devices, testing them individually can become cost prohibitive and complex. Proton testing provides such a compromise. Depending on the space environment and the application, proton testing can be a cost effective technique for evaluating parts. This paper presents some of the advantages and disadvantages in considering tradeoffs between protons versus heavy ion testing. Such a case is discussed of using a commercial video controller and CCD for a LEO system such as the International Space Station where COTS are heavily being considered. Possible risk mitigating steps are suggested to reduce the possibility of a catastrophic failure.
