摘　　要：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。Basic design methods about the magnetic shield of an X-ray spectrometer for Chang＇E Mission were introduced in this paper. The real magnetic field distribution was obtained through the measure experiment, and according to the measure results, the simulation to evaluate the magnetic shield effect was carried on. The results showed that the collimator can play a good role in magnetic shield to the electron.
