Abstract

Abstract. The results of a destructive single-event effect susceptibility radiation test of the PNI RM3100 magnetometer sensor, specifically the MagI2C ASIC (application-specific integrated circuit) on the sensor board are presented. The sensor is a low-resource commercial off-the-shelf (COTS) magneto-inductive magnetometer. The device was monitored for destructive events and functional interruptions during exposure to a heavy ion beam at the Lawrence Berkeley National Laboratory's 88′′ Cyclotron. The RM3100 did not experience any destructive single-event effects when irradiated to a total fluence of 1.4 × 107 cm−2 at an effective linear energy transfer (LET) of 76.7 MeV cm2 mg−1 while operated at nominal voltage (3.3 V) and elevated temperature (85 ∘C). When these results are combined with previous total ionizing dose tests showing no failures up to 150 kRad (Si), we conclude that the PNI RM3100 is extremely radiation tolerant and can be used in a variety of space environments.

PNI RM3100磁力计空间应用的单事件效应测试

摘要介绍了PNI RM3100磁强计传感器的破坏性单事件效应磁化率辐射测试结果，特别是传感器板上的magi2c ASIC(专用集成电路)。该传感器是一种低资源商用现货(COTS)磁感应磁力计。在劳伦斯伯克利国家实验室的88“回旋加速器”中，该设备在暴露于重离子束时被监测到破坏性事件和功能中断。在标称电压(3.3 V)和高温(85°C)下，以76.7 MeV cm2 mg - 1的有效线性能量转移(LET)照射总影响为1.4 × 107 cm - 2时，TheRM3100没有发生任何破坏性的单事件效应。当这些结果与之前的总电离剂量测试相结合时，显示没有高达150 kRad (Si)的失效，我们得出结论，PNI RM3100具有极高的耐辐射性，可以在各种空间环境中使用。

期刊介绍： Geoscientific Instrumentation, Methods and Data Systems (GI) is an open-access interdisciplinary electronic journal for swift publication of original articles and short communications in the area of geoscientific instruments. It covers three main areas: (i) atmospheric and geospace sciences, (ii) earth science, and (iii) ocean science. A unique feature of the journal is the emphasis on synergy between science and technology that facilitates advances in GI. These advances include but are not limited to the following: concepts, design, and description of instrumentation and data systems; retrieval techniques of scientific products from measurements; calibration and data quality assessment; uncertainty in measurements; newly developed and planned research platforms and community instrumentation capabilities; major national and international field campaigns and observational research programs; new observational strategies to address societal needs in areas such as monitoring climate change and preventing natural disasters; networking of instruments for enhancing high temporal and spatial resolution of observations. GI has an innovative two-stage publication process involving the scientific discussion forum Geoscientific Instrumentation, Methods and Data Systems Discussions (GID), which has been designed to do the following: foster scientific discussion; maximize the effectiveness and transparency of scientific quality assurance; enable rapid publication; make scientific publications freely accessible.
