| 摘 要： | 中国先进研究堆(CARR)旁的中子残余应力谱仪是我国第1台利用中子衍射方法测量残余应力的设备。它的样品台及部分附属设备从瑞典引进,结合CARR的实际情况,完成了概念设计、物理设计及机械加工,目前谱仪正在调试中。新的单色器屏蔽体起飞角在41°～109°连续可变,采用五维姿态调整台,方便灵活地调整单色器的位置。使用双聚焦Si(311)单色器,谱仪的分辨可以达到0.2%。一维中子位置灵敏探测器ORDELA1128N的主要指标与REST上使用的ORDELA1150N的相比有了很大改进。谱仪的附属设备多样,具备开展织构测量和材料原位拉伸等实验研究的能力。

| Abstract: | The neutron residual stress diffractometer for China Advanced Research Reactor (CARR) is the first instrument in China for the residual stress measurement using neutron diffraction method. Its sample table and some affiliated equipments were relocated from Sweden. According to the situation of CARR,the conceptional and physical design and mechanism fabrication were finished. Now the whole instrument is going to be put in commissioning. The take-off angle of new monochromator's shielding could be continuousl... |
