上海硬X射线自由电子激光装置首次出光 建成后能量达8GeV 全球同类装置仅两台
新华社10月21日报道，上海科技大学10月15日发布消息，硬X射线自由电子激光装置（SHINE）首次出光。该装置的4GeV连续波超导直线加速器已完成调试，18台波荡器投入运行，波荡器长4米、磁周期55毫米。
SHINE工程于2018年4月开工，法人单位为上海科技大学。装置建成后能量将达8GeV，覆盖0.2至15 keV光子能量范围，最高重复频率达1 MHz。建成后，它将成为全球仅有的两台同类型装置之一，另一台为美国的 LCLS-II-HE。项目目标于2027年底建成投用。

Shanghai's SHINE Facility Produces First Light; the 8 GeV Hard X-Ray Free-Electron Laser Will Be One of Only Two of Its Kind Worldwide
China's hard X-ray free-electron laser facility SHINE has produced its first light, Xinhua reported on October 21, citing an October 15 announcement by ShanghaiTech University. The facility's 4 GeV continuous-wave superconducting linear accelerator has been commissioned, and 18 undulators — each 4 meters long with a 55-millimeter magnetic period — are in operation.
Construction of SHINE began in April 2018, with ShanghaiTech University as the project's legal entity. When complete, the facility will reach 8 GeV, cover a photon energy range of 0.2 to 15 keV and operate at repetition rates of up to 1 MHz. It will be one of only two facilities of its kind in the world, the other being LCLS-II-HE in the United States. Completion and commissioning are targeted for the end of 2027.
