The Centre National de la Recherche Scientifique (CNRS) and the Commissariat à l'Energie Atomique (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 (SPM/SPrAM UMR 5819 and Laboratoire de Cristallographie), and CEA (DSM/DRFMC/SI3M/PCM and DSM/DRFMC/SP2M/NRS).

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

• In-situ study of atomic layers growth under ultra high vacuum is allowed in the Surface Ultra Vacuum (SUV) hutch.

• The multitechnic goniometer (GMT) working in air offers large possibilities to investigate interfaces between different elements or states of matter.

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

• Determination of the complete lattice unit cell (full strain tensor) of submicronic grains in polycristalline materials (MicroDiffraction)
  

Optics Hutch has been completely refurbished since January 2006. It has allowed to improve the X-ray Beam features coming in the experimental hutches (flux, spot size on sample and energy resolution...) and to achieve a microspot via a pinhole and two focussing mirrors.
