China plans to build a next-generation synchrotron radiation facility in Beijing, according to a researcher from Chinese Academy of Sciences, one of the country's top research institutes.
 
中科院一位研究员透露,中国计划在北京建造新一代同步辐射加速器。
 
 
Dong Yuhui, the researcher, said that the project is expected to start construction in Nov next year and will be completed within six years. The total investment will reach 4.8 billion yuan (698.4 million USD).
 
The facility, dubbed1 Beijing Light Source, will meet the national security demands and create aerospace2 materials among other products. It will provide high-resolution method to know substantial structures better.
 
Beijing Light Source will be the so-called fourth generation light source, and its key performance indicators3 would be higher than the third-generation ones.
 
It will create the brightest X-rays in the world, 70 times brighter than the US National Synchrotron Light Source II (NSLS-II) and 10 times brighter than Sweden's MAX IV, the strongest of its kind in the world so far.
 
Bright X-rays could help measure the atomic structure of various substances, and the higher brightness will help people to see more details of substances, something akin4 to using flashlight to see things, Dong said.
