Abstract:

The difficulty of materials inner stress detection is a barrier to engineering equipment research. And neutron scattering techniques is now recognized as the most precise method for mapping of inner residual stresses in materials or even components. Nine neutron scattering spectrometers of China Advanced Research Reactor (CARR) has been carried out thermal debugging, another five spectrometers are under construction. The thermal neutron spectrometer mentioned in this paper is one of the five spectrometers to be built in the neutron guide hall. It is anticipated that the instrument will be accomplished and available to users in 2018. The design of the hardware is mentioned. The function of positioning and control of the spectrometer can be carried out by the software. This spectrometer is available for material scientists to accomplish further studies with its function, and provides a good reference for spectrometer designing experts.
