中子准直器作为中子光学器件是中子散射谱仪的核心部件之一,是提高中子散射谱仪的分辨能力的有效途径,对于中子散射谱仪的性能有着非常重要的影响。根据CARR中子散射谱仪的应用需求,开展了最常用的Soller型中子准直器的研制工作。经过几年的试验摸索,已完成了Soller型中子准直器的加工制作工作(实物图如图1所示),掌握了制备工艺,并对其性能进行了测试。测试(图2)结果(图3)表明,自主研制的Soller型 Neutron collimator, as one of the core components of neutron scattering spectrometer, is an effective way to improve the resolving power of neutron scattering spectrometer. It has a very important influence on the performance of neutron scattering spectrometer. According to the application requirements of CARR neutron scattering spectrometer, the most commonly used Soller neutron collimator was developed. After several years of trial and error, Soller neutron collimator has been completed processing (physical map shown in Figure 1), mastered the preparation process, and its performance was tested. The results of the test (Figure 2) (Figure 3) show that Soller-type self-developed
