  The Shanghai Soft X-ray Free-Electron Laser facility (SXFEL) is being developed in two steps, the test facility SXFEL-TF and the user facility SXFEL-UF. The SXFEL-TF, which will generate 8.8 nm FEL radiation with the two-stage cascaded HGHG-HGHG or EEHG-HGHG scheme, is under commissioning at the SSRF campus. In the meantime, The SXFEL-UF, with designed wavelength in the water window region, began construction in November 2016, based on upgrading the linac energy to 1.5 GeV and building a second undulator line and five experimental end-stations. Status and future plan of the SXFEL is presented here.

  We study the two-color soft x-ray generation at the Shanghai soft X-ray Free Electron Laser (SXFEL) user facility based on the echo-enabled harmonic generation (EEHG) scheme. Using the twin-pulse seed laser with different central wavelengths, an preliminary simulation result indicates that two-color soft x-ray FEL radiation with wavelengths at 8.890 nm and 8.917 nm can be obtained from the ultraviolet seed laser. The radiation power is about 600 MW and the time delay is adjustable.
