China's large scientific infrastructure: the Shanghai Synchrotron Radiation Facility, or SSRF, is what's known as the country's first third-generation synchrotron radiation light source. The Nautilus-like building produces light that is hundreds of millions of times more powerful than an ordinary X-ray. It's known as synchrotron radiation and is created when charged electrons move close to the speed of light in a vacuum and change their direction. The process resembles spinning an umbrella fast in the rain, dispersing water droplets along the edge. It's a complex process, and seeing this huge scientific facility in operation is eye-opening. As CGTN's Liu Jiaxin reports, the technology is helping grow international understanding of the molecular world.
