The results of two radiation test campaigns on a low-cost commercial off-the-shelf magnetometer are presented. The test setup and the total ionization dose (TID) levels studied were designed to meet the requirements of a mission to land on Europa. Based on the Europa Lander Science Definition Team report, instruments inside an aluminum vault at the surface of Europa would need to withstand TID of up to 300 krad(SI). In order to evaluate the performance of the PNI RM3100 magnetometer, nine separate sensors were irradiated at two different facilities during two separate campaigns and under different configurations, including passive and active tests. Of the nine sensors, seven survived the TID of 300 krad(SI) while the other two sensors started presenting failures after reaching 150 krad(SI). Post-irradiation tests showed that eight of the nine sensors continued to work without appreciable degradation after stopping exposure, while one sensor stopped working altogether.

PNI RM3100磁力计的辐射容限，用于欧罗巴着陆任务

介绍了在低成本的商用现成磁力计上进行的两次辐射测试的结果。设计测试装置和研究的总电离剂量（TID）水平是为了满足登陆欧罗巴的任务的要求。根据Europa Lander科学定义小组的报告，Europa表面的铝制保险库内的仪器需要承受的最高TID为300  krad（SI）。为了评估PNI RM3100磁力计的性能，在两个独立的活动中以及在不同的配置下（包括被动测试和主动测试），在两个不同的场所对九个单独的传感器进行了辐照。在这9个传感器中，有7个在TID为300 krad（SI）的情况下幸存下来， 而另外两个在达到150 krad后开始出现故障 krad（SI）。辐照后测试表明，九个传感器中的八个在停止曝光后继续工作，而没有明显的退化，而一个传感器则完全停止工作。
