Abstract
We present and analyze system-level total ionizing dose (TID) tests of the simple analog system, point-of-load (PoL) dc/dc converter from 3D Plus, which was already qualified up to 50 krad(SiO2) based on component-level tests. TID response varied with the radiation facility for several parts; however, extensive testing with one part has shown significant differences in the TID level of functional failure observed for different operation modes (configurations): depending on the operating configuration of the device, the observed TID level of failure varies from about 60 krad(SiO2) to more than 400 krad(SiO2). These differences are depicted with the use of the safe operating area (SOA) plot for the system, which incorporates main system functional parameters. We also explore the potential utilization of the SOA concept in defining the system’s TID performance, employing a range of TID thresholds rather than relying on a singular value.
我们介绍并分析了对 3D Plus 的简单模拟系统、负载点 (PoL) 直流/直流转换器进行的系统级总电离剂量 (TID) 测试。几个部件的 TID 响应随辐射设施的不同而变化；然而，对一个部件进行的广泛测试表明，在不同操作模式（配置）下观察到的功能故障 TID 水平存在显著差异：根据设备的操作配置，观察到的故障 TID 水平从大约 60 krad(SiO2) 到超过 400 krad(SiO2) 不等。这些差异可以通过系统的安全运行区域图（SOA）来描述，其中包含了主要的系统功能参数。我们还探索了利用 SOA 概念定义系统 TID 性能的可能性，采用了一系列 TID 临界值，而不是依赖于一个单一的值。
期刊介绍：
The IEEE Transactions on Nuclear Science is a publication of the IEEE Nuclear and Plasma Sciences Society. It is viewed as the primary source of technical information in many of the areas it covers. As judged by JCR impact factor, TNS consistently ranks in the top five journals in the category of Nuclear Science & Technology. It has one of the higher immediacy indices, indicating that the information it publishes is viewed as timely, and has a relatively long citation half-life, indicating that the published information also is viewed as valuable for a number of years.
The IEEE Transactions on Nuclear Science is published bimonthly. Its scope includes all aspects of the theory and application of nuclear science and engineering. It focuses on instrumentation for the detection and measurement of ionizing radiation; particle accelerators and their controls; nuclear medicine and its application; effects of radiation on materials, components, and systems; reactor instrumentation and controls; and measurement of radiation in space.
