Major scientific and technological infrastructure is a large-scale and complex scientific research system that provides extreme research means for exploring the unknown world, discovering natural laws, and realizing technological change. It is also the material and technological basis for breaking through the scientific frontier and solving major scientific and technological problems of economic and social development and national security. The Outline of the Eleventh Five-Year Plan for National Economic and Social Development clearly lists 12 major national scientific and technological infrastructure projects, such as the spallation neutron source and large astronomical telescope projects. CIECC was deeply involved in formulating the National Medium- and Long-term Plan for the Construction of Major Scientific and Technological Infrastructure Projects (2012-2030), and clearly proposed 16 major national projects, such as the Submarine Scientific Observation Network and the High-Energy Synchrotron Radiation Source Verification Device.
CIECC provided consultative assessment services for the establishment and feasibility study of all these projects. So far, a number of facilities have been built and put into operation, and their overall performance has reached the international advanced level. Among them, the Shanghai Synchrotron Radiation Facility (SSRF) has supported the rapid development of life sciences, medicine, materials science, and other disciplines in China, and has achieved important results; the Pulsed High Magnetic Field Facility (PHMFF) has made China the third country to break through the 90 Tesla barrier after the United States and Germany; and the auxiliary heating system of the Experimental Advanced Superconducting Tokamak (EAST) has repeatedly created new world records of high-temperature plasma discharge. So, CIECC has made great contributions to China’s entry into the world’s forefront of science and technology.
