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 (UMR SyMMES CNRS-CEA/IRIG and Institut Néel), and CEA (DRF/IRIG/MEM).

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

CRG-IF beamtime can be asked both through the ESRF and the Soleil program committees.

Deadlines for proposal submission:

March 1st 2023 for ESRF beamtime and February 15th 2023 (5:00 PM) for CRG beamtime.

After the beamlime closure for the installation of new LaueMAX station, funded by MAGNIFIX project EquipeX+, external user beamtime should restart:

INS2 & GMT: 1rst-15th October 2023

LaueMAX : 15th January 2024

Last 5 years CRG-IF BM32 beamline science and capabilites are described in the report to the BeamLine Review Panel.

Two instruments are available to offer a complementary characterization of surfaces and interfaces in soft and hard condensed matter, with monochromatic and few 100 µms sized beam, by means of scattering X-ray techniques from 5 to 27 keV:

  • (1) In-situ study of atomic layers growth under ultra high vacuum is allowed in the In Situ Nanostructures and Surfaces (INS2) hutch.
  • (2) The multitechnic goniometer (GMT) working in air offers large possibilities to investigate interfaces between different elements or states of matter.

A Laue diffraction instrument designed for submicronic spatially-resolved white (polychromatic) beam diffraction. Beamsize: 300x300 nm2 Continuous energy spectrum in 5-22 keV range:

  • (3) Determination of the local orientation, strain (lattice paramaters) and stress at submicrometre scale in microstructures (2D maps and 3D profles) and microobject by Laue microdiffraction (LaueMax)

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
