The Shanghai Synchrotron Radiation Facility (SSRF) () is a synchrotron-radiation light source facility in Shanghai, People's Republic of China. Located in an eighteen-hectare campus at Shanghai National Synchrotron Radiation Centre, on the Zhangjiang Hi-Tech Park in the Pudong district.〔China economic net. "(En.ce.cn )." ''Shanghai particle accelerator to open its doors for business.'' Retrieved on 2009-05-12.〕 SSRF is operated by the Shanghai Institute of Applied Physics (SINAP). The facility became operational in 2009, reaching full energy operation in Dec 2012. ==Construction== It has a circumference of 432 metres, and is designed to operate at 3.5GeV, the highest energy of any synchrotron other than the Big Three facilities SPring-8 in Hyōgo Prefecture, Japan, ESRF in Grenoble, France and APS at Argonne National labs, United States. It will initially have eight beamlines. The particle accelerator cost 1.2 billion yuan (US$176 million). It is China's biggest light facility.〔 It is located under a building with a futuristic snail-shaped roof. The synchrotron opened to universities, scientific institutes and companies for approved research in May 2009.〔 Dec. 2004 - Sept. 2006: Building construction Jun. 2005 - Mar. 2008: Accelerator equipment and components manufacture and assembly Dec. 2005 - Dec. 2008: Beamline construction and assembly Apr. 2007 - Jul. 2007: Linac commissioning Oct. 2007 - Mar. 2008: Booster commissioning Apr. 2008 - Oct. 2008: Storage ring commissioning Nov. 2008 - Mar. 2009: ID Beamline commissioning Apr. 2009: The SSRF operation begins〔(【引用サイトリンク】title=Construction Schedule )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Shanghai Synchrotron Radiation Facility」の詳細全文を読む スポンサード リンク
