PAL-XFEL has operated general user program successfully from 2017 in both hard (2.5 – 14 keV) and soft (250 – 1300 eV) X-ray beamlines. Particularly in Soft X-ray Scattering and Spectroscopy (SSS) beamline, X-ray absorption and emission spectroscopy (XAS / XES) endstation has conducted general user programs.
In SSS beamline, second experimental instrument, Resonant Soft X-ray Scattering (RSXS) endstation, was built and open from 2020. This endstation mainly supports optical laser pump (800-nm-wavelength and harmonics) soft X-ray probe (400-1300 eV, covers 3d transition metal L2,3-edge, O K-edge, and part of 5f rare-earth element M4,5-edge) time-resolved RSXS experiments, with a time resolution better than 100 fs. Within less than a year, there have been several successful experiments, mainly in 3d transition metal compounds which are important magnetic and strongly correlated materials. The details of the endstation and selected experimental results will be introduced in the presentation.
