Core Viewpoint - The successful acceptance of China's first high-energy direct geometry inelastic neutron scattering time-of-flight spectrometer fills a significant gap in the country's capabilities for inelastic neutron scattering above 100 meV, enabling advanced studies of material's microscopic structures and dynamic properties [2][3]. Group 1: Instrument Capabilities - The high-energy inelastic neutron scattering spectrometer can measure both the spatial distribution and energy changes of scattered neutrons, allowing for the analysis of material's microscopic dynamic behaviors in momentum and energy space [3]. - It operates with an incident neutron energy range of 10-1500 meV, achieving an optimal energy resolution of 3% for dynamic excitation signals [3]. - The spectrometer supports a wide temperature range of 1.5-800 K and a magnetic field environment of up to 7T, covering most experimental scenarios for inelastic neutron scattering [3]. Group 2: Scientific Value - In high-temperature superconductivity research, the spectrometer can accurately measure spin fluctuations in superconductors, analyze their relationship with superconductivity, and provide critical experimental evidence for understanding high-temperature superconducting mechanisms [4]. - In the field of energy materials, it can track the diffusion processes of atoms and ions in lithium batteries and hydrogen storage materials, offering theoretical guidance for designing higher-performance energy materials [4]. - In biomedicine, the spectrometer enables the study of the dynamic behavior of biological macromolecules like proteins under near-physiological conditions, paving the way for new drug development [4]. Group 3: Future Prospects - The construction team of the spectrometer has initiated the development of a multi-field coupling loading analysis module, supported by national major scientific instrument development projects [4]. - With its acceptance and upcoming user access, the spectrometer is set to embark on a journey of scientific exploration, helping scientists uncover more mysteries of nature and providing strong support for the development of fundamental disciplines such as physics, chemistry, materials science, and biology [4].
