Organization

PAL-XFEL is the hard X-ray free-electron laser at Pohang Accelerator Laboratory (EXT-017). It provides femtosecond X-ray pulses for time-resolved diffraction and scattering experiments.

Access status

• Level: yellow (Negotiated Access)
• Rationale: PAL-XFEL hard X-ray FEL user facility; international beamtime access.
• Access URL: www.pal.postech.ac.kr
• Contact name: Office of Research Services
• Contact email: ors@depaul.edu
• Verification date: 2026-07-01

Relationship to DePaul

DePaul Physics ultrafast x-ray research (Eric Landahl, CSH-007) includes experiments at PAL-XFEL documented in peer-reviewed publications (full-text facility pass, July 2026). DePaul does not operate XFEL beamtime allocations.

Verification

• Status: likely (~)
• Confidence: 75/100
• Rationale: XFEL sub-facility resource for publication-evidence extraction; pub links pending curator review.
• Last verified: 2026-07-01
• Evidence:
• Curator — DePaul ultrafast x-ray program uses PAL-XFEL (distinct from Euro XFEL affiliation-only papers)
• PAL facility documentation
