[0002] The Spallation Neutron Source is a large-scale research platform for neutron scattering research and application. It provides an advanced research platform for cutting-edge research in many fields such as materials science and technology physics, chemistry and chemical engineering, resources and environment, new energy, life sciences, medicine, nanoscience, and for solving key issues that meet many of the country's major strategic needs.

[0003] A neutron scattering spectrometer is a device used in neutron scattering experiments, mainly to detect the microstructure and movement of matter.

[0004] The high-pressure neutron diffraction spectrometer is a neutron powder diffraction spectrometer that integrates two working modes, diffraction and imaging, is equipped with a relatively comprehensive set of special pressure environment equipment, and has high / low temperature and magnetic field environments, and has a certain degree of versatility. The spectrometer design optimizes the neutron optical path design, so that the spectrometer has two working modes, diffraction and imaging, and can obtain multi-scale sample structure information; the spectrometer is designed with two sample environments to match the needs of different pressure equipment, achieving large Q value coverage for small pressure equipment and high resolution for large pressure equipment; the spectrometer uses TO choppers and bandwidth-limited choppers to remove the fast neutron background of the incident neutron beam and select the neutron bandwidth. At the same time, the chopper frequency reduction operation mode is designed to double the d value coverage range of the 90-degree position detector; the switching of the diffraction / imaging working mode is achieved through the matching of the multi-segment neutron guide / collimation tube interchange system.

[0005] The existing close-packed neutron detector device has high requirements for positioning accuracy. The distance between each detector is relatively small.
