项目摘要

A sensor of fluxgate magnetometer on a space vehicle is exposed in space, so the sensor should be required working on a good condition in the wide range temperature from +200℃ to -160℃ with precise resolution.We developed a wide range temperature control box that is made of magnetic shield material. The system changes the temperature from +200 to -160℃, and it has a magnetic calibration coil and 6 channel thermocouples. We tested some kinds of sensor core at the range of high temperature region, from 20 to +200℃ in the first test step. The used core is made of Permalloy thin foil and it is winded around two kind bobbins that is made of Inconel and made of ceramics. In the next step, we tested these sensor cores at the low temperature range, from 20℃ to -160℃. At the same time, we improved the magnetometer electronics and we produce a model magnetometer that is similar to that of the Bepi-Colombo Mercury Research Vehicle. We obtained good data of temperature characteristics of 2 kind sensors at the wide range. And also we developed a magnetic moment measuring system and measured magnetization of satellite parts, instruments and satellite itself.In this study, we obtained the following.(1) A magnetic shielded temperature control system was built and it is able to control the temperature from +200℃ to -160℃. It is wide range temperature test system and it will be useful system for temperature test under the non magnetic field environment.(2) The temperature characteristics, sensitivity, drift, offset and noise of sensor were obtained for 2 kind sensor cores. The result of ceramic sensors showed excellent characteristics.(3) The high speed magnetic moment measuring system is working on a satellite EMC test of the magnetization for many instruments and satellites.

航天器上的磁通门磁力计的传感器暴露在太空中，因此要求传感器在+200℃至-160℃的宽温度范围内良好工作，并具有精确的分辨率。我们开发了宽范围温控箱该系统由磁屏蔽材料制成，温度从+200℃变化到-160℃，并具有磁校准线圈和6通道热电偶。我们在20℃的高温范围内测试了几种传感器核心。到第一个测试步骤中使用的磁芯由坡莫合金薄箔制成，并缠绕在由铬镍铁合金制成的两种陶瓷绕线管上。下一步，我们在低温下测试了这些传感器磁芯。温度范围从20℃到-160℃ 同时，我们改进了磁力计电子器件，并生产了与Bepi-Colombo水星研究飞行器类似的模型磁力计，我们获得了良好的温度数据。我们还开发了磁矩测量系统，测量了卫星部件、仪器和卫星本身的磁化强度。在这项研究中，我们得到了以下结果：（1）磁屏蔽温度控制系统。建立了能够控制温度从+200℃到-160℃的宽范围温度测试系统，它将成为无磁场环境下温度测试的有用系统。（2）温度特性、灵敏度、获得传感器的漂移、偏移和噪声2种传感器磁芯。陶瓷传感器的结果显示出优异的特性。(3)高速磁矩测量系统正在为许多仪器和卫星进行磁化强度的卫星EMC测试。
