【#Tech24H】China’s first high-energy direct-geometry time-of-flight inelastic neutron scattering spectrometer has passed acceptance. If conventional scientific instruments are likened to human eyes, this high-energy inelastic spectrometer is a super camera with extraordinary capabilities. It can not only see the static structure of matter but also probe the dynamic processes of atoms and molecules within materials on picosecond (one trillionth of a second) timescales, recording every instant of how atoms and molecules vibrate, rotate, and transfer energy. This major national instrument, dedicated to observing the structure and dynamics of the microscopic world, fills a gap in China’s capability for inelastic neutron scattering above 100 milli-electron volts.
