| 摘 要： | 介绍了双晶单色器出射光与入射光T型固定出口机构的工作原理，分析了双晶之间位置关系及尺寸确定所需遵循的原则，并根据这些原则提出一种基于T型固定出口机构的双晶单色器晶体间位置关系及尺寸的确定方法。该方法不仅能够满足双晶单色器的固定出口的工作要求，而且还优化了双晶的长度尺寸、消除了第二晶体微调的位置误差。最后举例论证了该方法的有效性。

| Abstract: | The principle of the T-shaped exit fixed mechanism of the exit beam and entrance one in the double-crystal monochromator is introduced, and requirements of deciding the ubiety and dimensions of two crystals are analyzed. According to these requirements, a method of deciding the ubiety and dimensions of two crystals based on the T-shaped exit fixed mechanism is put forward. The method can not only satisfy the working requirements of double-crystal monochromator, but also optimize the length of two crystals, moreover, it can eliminate the position error when fine adjusting the second crystal. The advantage of the method is testified by giving an example in the end. |
