介绍了嫦娥一号卫星X射线谱仪准直器磁屏蔽设计的基本思路,通过磁场点测实验得到了谱仪准直器的真实磁场分布,并且根据实验结果对谱仪准值器的磁屏蔽效果进行了模拟计算,由模拟结果可知该准直器对电子能起到较好的屏蔽作用。
The basic idea of the magnetic shield design for the Chang’e-1 satellite X-ray spectrometer collimator is introduced. The real magnetic field distribution of the collimator is obtained by the magnetic field point test. According to the experimental results, the magnetic shield The simulation results show that the collimator can play a good shielding effect on electrons.
