Hefei Advanced Light Facility (HALF), a major national science and technology infrastructure, is a fourth-generation synchrotron radiation facility in the low-energy range (2.2 GeV) based on diffraction-limited storage ring (DLSR) technology. It generates soft X-rays with over a hundredfold enhancement in brightness and coherence compared to third-generation synchrotron light sources. By pioneering novel experimental methodologies with unprecedented precision and sensitivity across spatial, temporal, and energy dimensions, HEFEI ADVANCED LIGHT FACILITY will serve as a pivotal research platform for probing microscopic particle behaviors, light-element structures, and dynamic changes in materials' electronic/chemical/spin states.

Upon completion, HALF will stand as the world’s most advanced low-energy synchrotron radiation light source. It will propel Hefei’s transformation into a global hub for photon science and applications, establish China’s full-spectrum advanced light source system spanning all energy ranges, and accelerate advancements in cutting-edge technologies, innovation ecosystems, strategic industrial modernization, and national scientific competitiveness.
