The Nuclear Electronics Group consistently takes major national strategic demands as its mission. Oriented toward the frontiers of nuclear physics and deep-space exploration missions, it is dedicated to overcoming technical bottlenecks in high-end readout electronics.

Over the past five years, the laboratory has led the development of the readout electronics system for the TPC array detector in several major endeavors, including the "Tianwen-1" Mars Energy Particle Analyzer, the CAS' Strategic Priority Program (Category B), the National Key Research and Development Program, and the National Major Scientific Instruments Development Project (CEE).

Relying on national major scientific and technological infrastructures such as the Heavy Ion Research Facility in Lanzhou (HIRFL) and the High Intensity heavy-ion Accelerator Facility (HIAF), the group focuses on research areas including front-end readout electronics, high-speed data acquisition and processing, and radiation-hardened electronics. 

With profound expertise in application-specific integrated circuit design and advanced nuclear electronics, the group has established a full-chain "chip–system" development capability. Its achievements have strongly supported cutting-edge research in nuclear physics and have been widely applied in fields such as nuclear medical imaging and spaceborne detection. 

Additionally, the group continuously cultivates high-level innovative talents in the field of nuclear electronics, committed to providing key technical support for major national scientific facilities and regional economic development.  It has published numerous papers in high-level domestic and international SCI journals, and obtained multiple national invention patents and software copyrights.
