Description

technical field [0001] The invention belongs to the technical field of experimental equipment, in particular to an experimental equipment for measuring the internal stress of a solid-state battery based on neutron diffraction. Background technique [0002] The application of neutron scattering technology began in 1946. Researcher Shull of the Oak Ridge National Laboratory in the United States used a reactor-based neutron source to carry out neutron diffraction experiments for the first time, aiming to analyze the microscopic static structure inside the material. The neutron diffraction analysis technology is the same as The X-ray analysis method is similar, and the strain is calculated according to the displacement of the diffraction peak, and then converted into a stress result. At present, many neutron scattering laboratories in the world have established neutron diffraction stress spectrometers for measuring stress. [0003] However, the position of the stage on the neutr...
