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 continuously changeable from 41° to 109°. The position of monochromator could be adjusted conveniently and flexibly by a five axis table. The resolution of this diffractometer could reach 0.2% using the double focusing Si(311) monochromator. The technical specification of one dimension neutron position sensitive detector ORDELA 1128N is better than that of ORDELA 1150N used on REST. The various affiliated equipments of instrument enable the diffractometer to measure the texture and tensional experiment in situ.
