In this study, we have investigated the temporal dynamics of the CDW in YBa2Cu3O6+x single crystal using time-resolved resonant soft x-ray scattering (tr-RSXS) at the newly developed RSXS endstation of the PAL-XFEL. Using infrared optical pump, CDW correlation changes within a few picosecond time window. Detailed results, i.e. temperature and fluence dependence, will be discussed in the presentation.
