The first neutron total scattering spectrometer in China has achieved fruitful results: more than 300 user experiments have been completed, and some technologies have achieved "0 to 1" breakthroughs
on August 14 that the Institute of High Energy Physics of the Chinese Academy of Sciences published a blog post yesterday (August 13),
announcing that the multi-physics spectrometer has completed more than 300 user experiments in the three years since its operation , becoming a model of collaborative innovation in the Guangdong-Hong Kong-Macao Greater Bay Area.
Introduction to Multiphysics Spectrometer
The multi-physics spectrometer was jointly built by the Spallation Neutron Source Science Center, Dongguan University of Technology and City University of Hong Kong. It is the first collaborative spectrometer built at the China Spallation Neutron Source, a major national scientific and technological infrastructure.
The key technical indicators of the multi-physics spectrometer are that
the neutron flux per unit power at the sample is at the leading level among similar international spectrometers , and the diffraction resolution and real space resolution of the spectrometer are at the best level among similar international spectrometers.
At the same time, a series of key technological breakthroughs were made during the development of the multi-physics spectrometer.
For the first time, a domestically produced position-sensitive helium triple-tube detector was successfully developed and put into engineering use. Its performance reached the international advanced level,
achieving a breakthrough from "0 to 1" , and laying a solid foundation for the subsequent independent development of spectrometer detectors.
The team independently developed
the first domestically produced software for neutron diffraction and pair distribution function data reduction , built a full chain of total scattering data acquisition and analysis technology, and realized the localization of neutron total scattering data reduction software
Results
Yin Wen, a researcher at the Institute of High Energy Physics of the Chinese Academy of Sciences and the person in charge of the multi-physics spectrometer, introduced that
in the three years since the multi-physics spectrometer was put into operation, more than 300 user experiments have been completed . The research fields include batteries and energy, chemistry and environment, alloy materials, rare earths and magnetic materials, etc. It has provided 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 the major needs of the country, industrial needs and basic research.
More than 100 high-level papers have been published in journals such as Nature.
significance
The multi-physics spectrometer provides key support for the "Chinese Academy of Sciences-Hong Kong Joint Laboratory of Neutron Scattering Science and Technology" and the "Guangdong, Hong Kong and Macao Joint Laboratory of Neutron Scattering Science and Technology" which were established successively.
