Abstract: Nuclear detection technology is the core supporting discipline for the research and development of nuclear science and technology. China Institute of Atomic Energy (CIAE) has successively provided more than 67 kinds of detectors, and more than seventy kinds of nuclear electronics instruments and devices (more than several thousand sets in total) for the research and development of nuclear science and technology in China, which makes an important contribution to the development of nuclear science in China. With the supports of the state, CIAE has carried out research on planar technology silicon detectors, compound semiconductor detectors, high-purity germanium detector, nuclear quadrupole resonance detector and high-temperature fission ionization chamber detector etc. since the 11th five-year-plan. Breaking through a series of key technologies, CIAE has developed a variety of advanced nuclear detectors or devices used in the fields of nuclear technology application, national security and national economy, and made new contributions to the country.
