Description
The Fermi chopper serves as the core key equipment of the high-energy inelastic neutron scattering spectrometer at the China Spallation Neutron Source (CSNS), and its technical performance directly determines the energy resolution of the spectrometer. At present, the spectrometer is equipped with a Fermi chopper applicable only to the low-energy range, which leads to obvious limitations in experimental application and research expansion.
To further improve the scientific capability of the high-energy inelastic spectrometer, we plan to carry out the research and development of a new high-energy-range Fermi chopper in the next two to three years. This report mainly introduces the overall R&D roadmap of the new high-energy Fermi chopper, clarifies the core technical indicators, and summarizes the key technical highlights.
