Several bending-magnet beamlines at the ESRF are operated independently by Collaborating Research Groups (CRGs). For administrative purposes, CRGs are third-party contractors to the ESRF, and each maintains a research program independent of the ESRF. Further information on CRGs is available from the CRG Liaison Office.

Users have two routes for accessing these beamlines:

  • One-third of the beamtime on these beamlines is managed through the ESRF public user program.
  • The remaining two-thirds is allocated by each CRG through an independent proposal process. Allocation procedures may differ slightly among CRGs.

Both routes are handled through the ESRF User Portal. The CRG Liaison Office can advise on proposal submission for CRGs.

Industrial applications

The ESRF’s mission includes interacting with and supporting European industry. Synchrotron X-rays permit analysis of industrial products under real conditions of manufacture and use, often in real time. The CRG Liaison Office and the Industrial and Commercial Unit can help identify appropriate resources at CRG beamlines for studying questions of concern to industry.
