中国先进研究堆(CARR)旁的中子织构谱仪是由德国引进的四圆谱仪改造而来,该谱仪通过单只3He管采集样品在各个取向上的晶面衍射数据,测量样品各晶面的极图从而获得晶粒取向分布。织构的研究对于预测材料性能、控制加工工艺、研究变形机理及晶间等有十分重要的意义。织构谱仪在调试完成投入使用前,需要准确地获得谱仪的零点和中子束的波长。因此,开发了针 The neutron texture spectrometer next to China Advanced Research Reactor (CARR) was modified by the introduction of a quadrupole spectrometer introduced by Germany that collects the diffraction data of the crystal facets in all orientations through a single 3He tube. The measurement sample The pole figure of each crystal face thus obtains the grain orientation distribution. The study of texture has very important significance for predicting the material properties, controlling the processing technology, studying the deformation mechanism and the intergranular. Before commissioning the fabric spectrometer, it is necessary to accurately obtain the zero point of the spectrometer and the wavelength of the neutron beam. Therefore, the needle was developed
