In 1994, the french CRG beamlines (Collaborating Research Group) have been created by the CNRS and CEA with the mission to (i) welcome, support and train the french scientists and (ii) develop cutting edge instrumentation and analysis tools.
The french CRGs are composed of 5 beamlines, placed on ports BM02, BM32, BM07, BM30 and BM16 at the ESRF synchrotron:
- D2AM (anomalous diffraction/scattering for material science),
- IF (diffraction/scattering, surfaces and interfaces),
- FIP (macromolecular crystallography in biology),
- FAME (absoption spectroscopy for earth and environmental sciences)
- FAME-UHD (same as FAME, but on ultra-diluted metallic elements)
For more than 20 years, the F-CRG beamlines have been complementary to the ESRF beamlines by a multi-technics and multi-scale approach. This is possible thanks to several specific instruments providing a unique sample environment. These state of the art instruments are maintained by initiatives and expertise from a network of interdisciplinarity laboratories in Grenoble or further away. Some Grenoble labs (Néel Institute, INAC/MEM, IBS, OSUG, SIMAP) provide permanent technical staff to the F-CRG beamlines. In addition, researchers from these labs and from a few additional labs (LMGP, CERMAV, INAC/SYMMES, LIPhy) play the role of “Local Contacts” or “Beamline Responsibles”. Except for the beam slots assignment, the mutualisation of the F-CRG beamlines is coordinated by a « Structure d’Exploitation » (SE), reporting to a governing board (CEA and CNRS founding agencies) and an external scientific advisory committee.
On average, more than 500 scientists (from France, Europe and rest of the world) come every year on the F-CRG beamlines, performing more than 180 experiments.
The 5 F-CRG beamlines at ESRF are accessible through the ESRF program committee (user portal) and through the SOLEIL common interface (sunset).
