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.

The proposed Shenzhen Superconducting Soft X-Ray Free-electron Laser (S3FEL) aims at generating FEL pulses from 1 nm to 30 nm. At phase-I, two undulator beamlines work at ehco-enable harmonic generation (EEHG) principle. The two undulators will cover the spectral ranges 2.3-15 nm (~83-539 eV) and 5-30 nm (~41-248 eV), respectively, when receiving electrons from 2.5 GeV superconducting linac. However, the generated FEL radiation is sensitive to various electron beam properties, e.g., its energy profile influenced by collective effects such as Coherent Synchroton Radiation (CSR), especially at high harmonics. To generate intense full coherent FEL radiation at ultra-short wavelength, a novel technique of EEHG cascaded harmonic lasing method is also considered. Physical design and FEL performance are described in this paper.
