摘要

快速等离子体调查(FPI)是美国国家航空航天局磁层多尺度空间物理任务上的一套仪器,旨在研究地球磁层中的磁重联。在这项工作中,为 FPI 开发了一个微通道板 (MCP) 电流预测模型,以自主监测设备电流。本文介绍了对 FPI 粒子分光计中的微通道板电阻的分析结果,以及一个新模型,该模型结合了 MCP 电阻的物理信息模型和 FPI 仪器温度的经验模型。这种改进的 MCP 电阻估算方法可以更精确地确定 MCP 的额定电流,从而准确检测电流异常。

Automated Current Monitoring for Microchannel Plates on Fast Plasma Investigation
The Fast Plasma Investigation (FPI) is an instrument suite aboard NASA’s Magnetospheric Multiscale space physics mission, which is designed to study magnetic reconnection in the Earth’s magnetosphere. In this work, a predictive model of microchannel plate (MCP) current was developed for FPI to autonomously monitor the device currents. The results of an analysis of the resistance of the microchannel plates included in the FPI particle spectrometers are presented along with a new model that combines a physically-informed model of MCP resistance with an empirically-derived model of FPI instrument temperature. This improved estimation of MCP resistance allows for a more precise determination of nominal MCP current, enabling accurate detection of current anomalies.
