PAL-XFEL Call for R&D beamtime Proposals
Information for R&D beamtime
PAL-XFEL operates the R&D beamtime program independent from general user beamtime. It is opened for the experiments that meet the following criteria.
- Establishing new experimental techniques or instruments at PAL-XFEL
- Proving critical performance of PAL-XFEL
- New users with no experience in XFEL experiments
- COVID-19 related research using PAL-XFEL
- Time resolved SFX with solution mixing and injection technique
- Applications of nano-focused hard X-ray FEL
- Applications of the self-seeded XFEL
R&D beamtime proposals will be decided by PAL internal review. Please contact for more details and submission of the proposal to PAL-XFEL Beamline (palxfel-beamline@postech.ac.kr)
Schedule for R&D beamtime
Although the PAL-XFEL takes the R&D proposal throughout the year, the evaluation will be carried out on the following schedule.
- The proposal deadline for the first half-year of 2022: Sep 5, 2021
- The result will be announced within two weeks after the deadline.

User Information and Obligations
- All visiting users must register the PAL system and attend a radiation safety course.
- All applicants are required to contact the PAL-XFEL staff in advance to discuss the experimental details and submit a beamtime application.
- The beamtime proposal must be submitted by the principal investigator (PI) of the research team. Students are ineligible.
- In case of change (or addition) of the samples or experimental setup specified in the proposal, users must obtain the agreement of PAL-XFEL and KOSUA (Korea Synchrotron User Association) prior to the beamtime. PAL-XFEL will provide the help for implementing such change/addition, but is not responsible for the plan that is not in the original beamtime proposal.
- For all kinds of beamtime proposals, an End of Run Report should be submitted to the user office of PAL within one year after finishing the experiment.
- Proposals are required to be written in English.
- PAL charges users in accordance with the Government policy. For non-proprietary research, the fee is KRW 250,000 per shift (12 hrs). For proprietary research, the fee is KRW 50,000,000 per shift.
