Welcome to the National Synchrotron Radiation Laboratory (NSRL). NSRL is the first dedicated synchrotron radiation facility in China, which locates on the West Campus of the University of Science and Technology of China (USTC), in Hefei, Anhui Province. It is one of the key issues of China’s investments on large-scale scientific research facilities. Its construction began on Nov. 20, 1984, and completed with a national review in Dec. 1991. After Phase II Project from 1999 to 2004 and Upgrading from 2012 to 2014, NSRL now owns a fully upgraded soft X-ray synchrotron radiation facility. The synchrotron is close to the 3rd generation level, and the facility is now with five ready-to-use endstations: combustion and flame, soft X-ray microscopy, catalysis and surface science, angle resolved photo-emission spectroscopy, atomic and molecular physics. It has six other beamlines now open for future endstations. The superior radiation, together with the well-designed beamlines and endstations, allow national-wide scientists to perform cutting edge scientific experiments, which are otherwise impossible in their home laboratories. The researches cover physics, chemistry, life sciences, material sciences, surface sciences, metrology, medicine, microscopy, instrumentation, and so on. As a government supported, user-oriented large-scale scientific facility, we enthusiastically welcome researchers from various fields coming to carry out your state-of-the-art research with us.
