The objectives of this project are to design and install at the SOLEIL synchrotron radiation source a metrology test facility for the R&D of optical components and detectors. We propose to build, on a bending magnet, three optical branches dedicated to VUV, soft X-rays and hard X-rays energy ranges to cover few eV to 28 keV. This installation will first address the needs of the SOLEIL experimental groups (Optics and Detectors) and will be used by a large community.This beamline will also be valuable as a general-purpose beamline to prepare, test and set up a wide range of experiments. Several problems will be studied at VUV or X-ray wavelengths: reflectivity measurements or gratings diffraction efficiency, scattering measurements and performance test of optical components. The use of X-ray beams for the characterization of optical surface shapes is also considered.
This project is build in collaboration with the Laboratoire National d’Essais (LNE)) and the CEA DIF. For the LNE, the metrology beamline of SOLEIL could become the national primary standard source. For the CEA DIF, the use of this beamline is very important to characterize with very high accuracy all diagnostics design for the Megajoule laser.
