China's large-scale research apparatus "Shanghai Light Source" accomplished

By Zou himfr

Shanghai Xinhua April 29 a total buying into of about 12 billion so far the biggest of China's biggest technical apparatus - the "Shanghai Synchrotron Radiation Light Source" Today in Shanghai Zhangjiang Hi-Tech Park formally accomplished and open for users at dwelling and abroad. Member of the Political Bureau of the CPC Central Committee, State Councilor Liu came to the culmination observance, and constituents of the CPC Central Committee Political Bureau, Shanghai Municipal Party Committee Secretary Yu Zhengsheng, vice head individual of NPC Standing Committee, CAS President Lu Yongxiang, leader of the Chinese Academy of Engineering Xu culmination of the widespread start device.

If the clinic for X-ray of human skeletal components and body-fluid vessels, "camera", then "the Shanghai Synchrotron Radiation Light Source" (hereinafter mentioned to as the "Shanghai Light Source") handed out by the super X-ray micro-world information will convey an "imaging revolution" -- - It will use X-ray appliances than commonplace lightweight on the billion-fold, powerful synchrotron emission millions of times the material micro-optical "imaging", for numerous localities of cutting-edge study and one of the most sophisticated device irreplaceable.

70s from the last century, the world's built, and construction of synchrotron radiation light source device has more than 60. In China, the first-generation synchrotron radiation light source is "Beijing Light Source", the second-generation light source is the National Synchrotron Radiation Laboratory in Hefei, the third-generation light source is the "Shanghai Light Source."

In the international community has built 20 third-generation synchrotron radiation light source, the "Shanghai Light Source" energy ranking fourth in the world, second only to Japan, the United States, Europe, the facility. Hefei and second-generation synchrotron radiation light source compared to the third-generation "Shanghai Light Source," the electron beam emittance of about 4 nano-radian, a difference of nearly 40 times the brightness of its difference of about 1600 times (about three order of magnitude) . "Shanghai Light Source" owner of the high-intensity, high-brightness, high stability properties, can be used to engage in the life sciences, materials science, environmental science, medicine, pharmacy and other cutting-edge multi-disciplinary basic research, as well as micro-electronics, petroleum, medical diagnosis and other high-tech development and application of experimental research.

Open distributing of technical gear is a prominent feature. "Shanghai Light Source" with more than 60 years construction the capability of Article beamline, will be at the identical time hundreds of Experiment Station to supply infrared lightweight to a kind of hard X-ray synchrotron emission lightweight, to the user-ray appliance will be for more than 5000 hours /year. Up to now, the "Shanghai Light Source," has obtained 78 nationwide universities to use the submission 301, for a total of 2868 localized time 23,000 hours.

"Shanghai Light Source," December 25, 2004 ground-breaking work by the Chinese Academy of Sciences jointly with the Shanghai Municipal People's Government to apply to the national construction, by the Chinese Academy of Sciences, the construction of the Shanghai Institute of Applied Physics. - 21393
