2026-2nd Call for Proposals at PAL-XFEL

We invite scientists worldwide to submit proposals for general user beamtime experiments at PAL-XFEL (Pohang Accelerator Laboratory – X-ray Free Electron Laser) from August to December 2026. PAL-XFEL has three beamlines, two for hard X-ray experiments (XSS: X-ray Scattering and Spectroscopy, NCI: Nano Crystallography and Coherent Imaging) and one for soft X-ray experiments (SSS: Soft X-ray Scattering and Spectroscopy). The access to PAL-XFEL is open to the international scientific community, with the requirement that foreign users collaborate with Korean scientists being local contacts. Additionally, all applicants must contact PAL-XFEL staff scientists to discuss experimental details before submitting a beamtime proposal. There is no fee for proposal submission, but charges will apply when the experiment is conducted, as per government policy. Please register as a user of PAL and submit an application form of the PAL-XFEL proposal via the website ([https://pal.postech.ac.kr/en/index.do](https://pal.postech.ac.kr/en/index.do)).
