On the morning of October 9, the launching ceremony of the main equipment of X-ray Free Electron Laser Experimental Device (SXFEL) was held in Zhangjiang Park, Shanghai Institute of Applied Physics, Chinese Academy of Sciences. The ceremony was presided over by Wang Dong, engineering manager, Shanghai National Science Center Chip) leadership, the overall project team, engineering manager and engineering and technical personnel representatives attended. X-ray free electron laser test device by the Chinese Academy of Sciences and the Ministry of Education jointly build the project unit for the Chinese Academy of Sciences Shanghai Institute of Applied Physics, co-construction unit for Peking University. December 30, 2014 the project officially started construction period of 3 years. In his speech, Chief Engineer Yin Lixin said that after the successful installation of DCLS equipment and the commissioning of the beam in late September, our technical team and engineering installation team were transferred to SXFEL equipment installation. The installation team will comprehensively summarize DCLS equipment installation experience, further strengthen technical management in SXFEL equipment installation, and install equipment with the goal of high quality, high efficiency and safety, and strive to complete equipment installation and deliver beam debugging before the end of the year. The project team leader and engineering chief scientist Zhao Zhentang, researcher, delivered a speech and announced that the main equipment installation was officially launched. He stressed that Shanghai Institute of Materia Medica trained many teams to develop excellent abilities and techniques to meet the higher standards Control engineering quality, the SXFEL project into a boutique project. Zhao Zhentang said that the Chinese Academy of Sciences "take the lead in action" plan on science and technology innovation put forward new requirements as Zhangjiang comprehensive national science center of important science facilities, SXFEL opened a new generation of light source prelude, the project will soon be soft X-ray The construction and operation of facilities such as free-electron laser user devices are opening up and accelerating their march toward science and technology innovation centers with global influence, which plays an important role in promoting them.
