The General Technology Center coordinates four professional technical teams: the Mechanical Technology Group, the Collimation Conditions Technology Group, the Electrical and Electromagnetic Compatibility Group, and the Radiation Safety and Protection Group. Focusing on the construction and operation needs of national major scientific and technological infrastructures, the center provides full-chain, integrated technical support and innovative services, laying a solid technical foundation for scientific research breakthroughs in heavy-ion physics and related fields of the institute.

The center is deeply engaged in the field of technologies related to particle accelerators and major facilities, including the operation, maintenance and upgrading of the Heavy Ion Research Facility in Lanzhou (HIRFL), full-process technical support for the High Intensity heavy-ion Accelerator Facility (HIAF), key technology research and development for the 300MeV proton-heavy ion accelerator of the Space Environment Simulation and Research Infrastructure (SESRI) of Harbin Institute of Technology, construction of the Proton Radiation Effects Facility (PREF) of the Xinjiang Technical Institute of Physics and Chemistry, and independent development of the Second generation heavy Ion Medical Machine (SIMM). Its work covers the entire cycle of civil engineering planning, system design, equipment development, installation and commissioning, and operation and maintenance support, forming a multi-disciplinary collaborative technical system integrating mechanics, alignment, electrical engineering and radiation protection.

The center attaches great importance to talent team building and technological innovation breakthroughs. It currently has a scientific research and technical team with a reasonable structure and outstanding professional capabilities. The team continuously promotes the in-depth integration of cutting-edge technologies and engineering practices, and has achieved a series of important results in fields such as digital twin modeling, intelligent alignment, multi-source Monte Carlo simulation, broad-energy-spectrum neutron detection, and ionizing radiation metrology. It has successfully established the highest γ metrology standard of CAS, and independently developed key equipment such as a high-precision rotating beam intelligent delivery system and a personal dosimeter distributed personnel access management system.

In the future, the General Technology Center will continuously strengthen multi-disciplinary collaborative research capabilities, strive to build a domestically leading and internationally renowned general technical support and innovation platform for major facilities, and deepen research in fields such as accelerator mechanical design, digital technology, radiation protection, and electrical support.
