Chinese Academy of Sciences' Multi-Physics Spectrometer 300+ User Experiments in 3 Years
TapTechNews August 14th news, yesterday (August 13th), the Institute of High Energy Physics, Chinese Academy of Sciences released a blog post, announcing that the multi-physics spectrometer has completed more than 300 user experiments in the past three years, becoming a model of collaborative innovation in the Guangdong-Hong Kong-Macao Greater Bay Area.
Introduction of the Multi-Physics Spectrometer
TapTechNews note: The multi-physics spectrometer is jointly built by the Spallation Neutron Source Science Center, Dongguan University of Technology and City University of Hong Kong, and is the first cooperative spectrometer built on the China Spallation Neutron Source, a major national scientific and technological infrastructure.
The key technical indicators of the multi-physics spectrometer, the neutron flux per unit power at the sample position is at the leading level among international similar spectrometers, and the diffraction resolution and real-space resolution of the spectrometer have reached the best level among international similar spectrometers.
At the same time, during the development of the multi-physics spectrometer, a series of key technological breakthroughs have also occurred. The first domestic position-sensitive helium-3 tube detector was successfully developed for the first time and achieved engineering application, with its performance reaching the international advanced level, achieving a from 0 to 1 breakthrough, laying a solid foundation for the subsequent independent development of spectrometer detectors.
The team independently developed the first domestic software for neutron diffraction and data reduction of pair distribution function, constructed the whole chain of full scattering data acquisition and analysis technology, and realized the localization of neutron full scattering data reduction software.
Results
Yin Wen, a researcher at the Institute of High Energy Physics, Chinese Academy of Sciences and the person in charge of the multi-physics spectrometer, introduced that in the past three years of operation of the multi-physics spectrometer, more than 300 user experiments have been completed, and the research fields include batteries and energy, chemistry and environment, alloy materials, rare earth and magnetic materials, etc., providing a structural research platform with different degrees of order for the fields of materials science, physics, chemistry, and environment, and has achieved a number of important results in serving national major needs, industrial needs and basic research fields, and has published more than 100 high-level papers in journals such as Nature.
Significance
The multi-physics spectrometer is the first large-scale scientific experiment facility in which Hong Kong and Macao regions participated in the investment and construction. It supports the cutting-edge research and technological development of universities, research institutes and enterprises including the Guangdong-Hong Kong-Macao Greater Bay Area, and has an irreplaceable exemplary and leading role.
The multi-physics spectrometer provides key support for the Chinese Academy of Sciences - Hong Kong Region Neutron Scattering Science and Technology Joint Laboratory and the Guangdong-Hong Kong-Macao Neutron Scattering Science and Technology Joint Laboratory established successively.
