Zhangjiang to build hard X-ray free-electron laser by 2025


The hard X-ray free-electron laser, being constructed at Zhangjiang National Innovation Demonstration Zone, is scheduled to be completed by 2025, equipped with 10 experimental stations, the Shanghai Nuclear Society announced recently at its 40th anniversary event.

The laser device is the scientific and technological infrastructure project with the largest ever amount of investment and longest construction period in China.

After its completion, the device, together with the existing Shanghai Synchrotron Radiation Facility (SSRF), the soft X-ray free-electron laser and the Shanghai Ultra-short and Ultra-intense Laser Facility (SULF), will form the world’s largest photonic science facilities group with the strongest comprehensive capability.

According to Zhao Zhentang, vice-president of the Shanghai Advanced Research Institute, Chinese Academy of Sciences, its superconducting accelerator will provide high-resolution imaging, ultra-fast process exploration and advanced structure analysis, among other cutting-edge research measures for physics, chemistry, life sciences, materials and energy sciences.

Official data shows that since the SSRF was put into service in May 2009, it had received more than 40,000 users, provided more than 280,000 hours of experimental time, undertaken more than 10,000 projects, and published more than 4,500 research papers by November 2018.
