Realize localization! High performance and large area boron carbide thin film for neutron detectors successfully developed in China
The reporter learned from the Institute of High Energy Physics of the Chinese Academy of Sciences that recently, the Chinese Spallation Neutron Source (CSNS) detector team successfully prepared high-performance and large-area boron carbide film samples to meet the needs of neutron detectors by using the self-developed special device for magnetron sputtering large-area boron plating, and realized the localization of key technologies and devices of neutron detectors.With the upcoming launch of the China Spallation Neutron Source (CSNS) Phase II project, the proposed neutron spectrometer urgently requires new neutron detectors with large area, high efficiency, and position sensitivity...
