Description
PAL, established in 1988 with full support from the Pohang University of Science and Technology, has acted as a powerhouse to support basic science and technology in Korea and has secured a competitive edge frontier after making ceaseless efforts. PAL is now operating PLS-II and PAL-XFEL.
PLS-II is the 3-rd generation synchrotron with 3-GeV beam energy and 5.8 nm emittance. Thirty-six beamlines are operational for user-service operation. PAL-XFEL is a hard X-ray free-electron laser facility based on 10-GeV normal conducting linac. One hard X-ray and a soft X-ray FEL are operational for user-service operation.
The PAL-XFEL has demonstrated excellent timing stability and unprecedented peak brightness since its start of user service operation in June 2017, outperforming other XFEL facilities worldwide. The 18-fs timing stability in the XFEL allows excellent pump-probe time-resolved experiments with low-timing jitter. A self-seeding scheme enables us to produce a higher peak brightness of the XFEL with a narrow bandwidth: the peak brightness of 3.2 x 1035 photons/(s·mm2·mrad2·0.1%BW) at 9.7 keV and the bandwidth of 0.19 eV, the best to date. To provide more beamtime to users, we started the 2nd hard X-ray FEL line project in 2024 and will finish it by 2027.
For our current or potential scientific users, we will continue to strengthen our capacity, scientific programs, and industry engagement and maximize our impact as a major contributor to the cutting-edge future of science in Korea.
