InterFace Beamline

dedicated to

Surfaces and Interfaces

The Centre National de la Recherche Scientifique (CNRS) and the Commissariat à l'Energie Atomique et aux énergies alternatives (CEA) have jointly constructed and now operate the CRG-IF beamline at ESRF in order to propose powerful X-ray beams to french surface researchers. One third of the beamtime is allocated in counterpart to the european scientific community. This beamline opened at the beginning of the ESRF, was the first CRG Beamline operational. BM32 is now composed of technical and scientific staff coming from CNRS (INP/SPrAM UMR 5819 and Institut Néel), and CEA (DSM/INAC/SP2M/NRS).

CRG-IF beamlime is member of the 5 french beamlines located at the ESRF forming the F-CRG facility.


Two instruments are available to offer a complementary characterization of surfaces and interfaces in soft and hard condensed matter:

  • (1) In-situ study of atomic layers growth under ultra high vacuum is allowed in the In Situ Nanostructures and Surfaces (INS) hutch.
  • (2) The multitechnic goniometer (GMT) working in air offers large possibilities to investigate interfaces between different elements or states of matter.

A new instrument (since march 2006) designed for submicronic focussed white beam (Laue) diffraction:

  • (3) Determination of the local orientation and complete lattice unit cell (full strain tensor) of submicronic grains in polycristalline materials (Laue MicroDiffraction)

Beamtime can be allocated by submitting proposals to two scientific program committees:

  • French or CRG beamtime through French committees (shared with SOLEIL synchrotron committees)
  • standard ESRF beamtime through ESRF international committees.

When choosing the suited instrument for your experiments during the electronic submission procedure please:

  • for UHV + goniometer in INS hutch (former name SUV)                                           select                IF-INS
  • for GMT goniometer (monochromatic beam) in GMT hutch                                     select                IF-GMT
  • for Laue Microdiffraction installation (white beam) in GMT hutch                        select                IF-µLaue
