Experimental Software Design of Neutron Residual Stress Diffractometer at China Advanced Research Reactor

The experimental software of the neutron residual stress diffractometer at China Advanced Research Reactor (CARR) was designed. According to the principle of residual stress measurement by neutron diffraction and the geometry of diffractometer, the measurement procedures were analyzed and the functions needed for residual stress measurement were proposed. Based on the motion control and data acquisition system of the diffractometer, the implement method of these functions was designed. Then the software was realized by LabVIEW language and tested by neutron beam. The experimental software for CARR neutron residual stress diffractometer was successfully accomplished.
