TL;DR: The Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) in South Korea has now entered operation with a timing jitter of just 20 fs.

TL;DR: PAL-XFEL as mentioned in this paper, a 1-nm hard X-ray free-electron laser (FEL) facility based on a 10-GeV S-band linear accelerator (LINAC), is achieved in Pohang, Korea by the end of 2016.

TL;DR: From initial commissioning and performance testing of the beamline, it is observed that BL10B beamline can perform XRS and XAFS measurements successfully.

TL;DR: A new time-resolved Resonant Soft X-rays Scattering endstation developed at the Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) can deliver a soft x-ray probe with a time resolution of ∼100 fs without jitter correction and the temporal dynamics of a charge density wave on a high-temperature cuprate superconductor are demonstrated.

TL;DR: In this article, the authors introduced a new time-resolved Resonant Soft X-ray Scattering (tr-RSXS) endstation developed at the Pohang Accelerator Laboratory Xray Free Electron Laser (PAL-XFEL), which has an optical laser (wavelength of 800 nm plus harmonics) as the pump source.
