Description
The Multi-Physics Instrument (MPI) is the first neutron total scattering instrument based on the China Spallation Neutron Source (CSNS) in China, which is jointly constructed by Dongguan University of Technology, the Institute of High Energy Physics, CAS and City University of Hong Kong. This project was begun in September 2018 and completed in June 2021, with its comprehensive performance reaching the international advanced level of similar Instruments. The MPI features a large range of detector coverage angles, high neutron flux, and high real-space resolution, fulfilling to structural analysis of materials with different degrees of structural order, including liquids, glasses, nanomaterials, and crystalline materials. It focuses on the structural research of materials with long-range order and local disorder, as well as materials with long-range disorder and medium-range order. The MPI is equipped with various sample environments to facilitate studies on the structural evolution of materials under various in-situ conditions such as temperature, pressure, stress-heat coupling, and charge-discharge, covering research areas including batteries and energy, chemistry and the environment, alloy materials, rare earths, and magnetic materials. It provides a research platform for materials with different degrees of structural order in the fields of materials science, physics, chemistry, and the environment.
