Feng, C. Comissioning progress and advanced FEL experiments at the SXFEL facility JACoW Publishing Geneva, Switzerland The Shanghai soft X-ray Free-Electron Laser facility (SXFEL) is the first X-ray FEL facility in China. The construction of the SXFEL facility was finished recently. The output photon energy of the SXFEL can cover the whole water window range. Except for the self-amplified spontaneous emission, various seeding technques have also been adopted for improving the performances of the SXFEL. Here we presents an overview of the SXFEL facility, including the layout and design, construction status, commissioning progress and future plans.
