The Shanghai Soft X-ray Free-Electron Laser (SXFEL) is expected to open to users by the end of this year to greatly facilitate research into the nanoscale world.

The SXFEL, the first X-ray free-electron laser user facility in China, is known as the fourth-generation light source. It can photograph and film molecules, providing a revolutionary research tool for physics, biology, chemistry and other research areas.

It has made a breakthrough in the development of the X-ray free-electron laser in China. (Xinhua)
