CRG beamtime access

There are two routes to access beamtime on a CRG beamline:

• One-third of the scheduled beamtime on CRG beamlines is managed through the ESRF public user program, with proposals being submitted twice a year, see public access beamtime webpage.
• The remaining two-thirds of the scheduled beamtime is “private” and allocated by each CRG’s own beamtime allocation procedures, see next section.

Both routes are handled through the ESRF User Portal. While all efforts are made to make proposal submission as consistent as possible, by the nature of CRGs, the procedures to apply for private beamtime may differ slightly from beamline to beamline. The CRG Liaison Office can advise on proposal submission for CRGs.
