The China Institute of Atomic Energy has successfully completed and brought into operation a state-of-the-art quantum radioactivity metrology laboratory, along with a 'multi-purpose in one line' production and research platform dedicated to ionization radiation metrology-level equipment. This milestone achievement addresses a long-standing gap in China's domestic capabilities concerning low-temperature quantum magnetocalorimeters, signifying that China has now attained a globally advanced standing in quantum radioactivity metrology technology.
As the pioneering innovative platform in China built upon the principles of magnetocalorimetry, the laboratory has substantially enhanced the resolution of γ-ray detection and bolstered analytical prowess for critical nuclides. It has achieved a groundbreaking zero-to-one advancement in signal detection employing the magnetocalorimetry principle within China.
The laboratory is outfitted with cutting-edge dilution refrigerators, enabling the testing of quantum microcalorimeter devices at ultra-low temperatures. Utilizing these sophisticated facilities, the research team is poised to undertake pertinent studies and establish a comprehensive quantum metrology standard system.
Established in 1950, the China Institute of Atomic Energy stands as a pivotal institution in China's nuclear scientific research landscape. As a subsidiary of the China National Nuclear Corporation, it encompasses six primary research institutes.
