Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL)


Pohang Accelerator Laboratory X-ray Free Electron Laser (PAL-XFEL) project was started in 2011 for the generation of X-ray FEL radiation in a range of 0.1 to 6 nm for users. The facility has the space for five undulator lines in total; three hard X-ray (HX) undulator lines and two soft X-ray (SX) undulator lines.
Currently, one HX undulator line and one SX line were installed and are ready for user service operation. This project has been successfully constructed and commissioned by the end of 2016. It has now started the user service from June, 2017.
There is also a synchrotron facility in Pohang, PLS-II.

      • PAL-XFEL achieved saturation of a 0.144 nm FEL beam on Nov. 27, 2016, making it the third hard X-ray (XFEL) in the world, following LCLS in 2009 and SACLA in 2011.
      • To be one of the leading XFELs in the world, PAL-XFEL started the user service in June 2017.
