COMMISSARIAT À L'ÈNERGIE ATOMIQUE
The French Atomic Energy and Alternative Energies Commission (CEA) is a public research organization of a scientific, technical and industrial nature. A major player in research, development and innovation, the CEA is active in four areas: defense and security, low-carbon energy (nuclear and renewable), technological research for industry and fundamental research (material and life sciences). With its recognized expertise, the CEA is involved in setting up collaborative projects with numerous academic and industrial partners.
CEA EXPERIMENTAL EQUIPMENT
The experimental chamber, CASTOR, is used to analyze thin layers in the nanometer range, using monochromatic X-rays provided at the Metrology beamline of SOLEIL synchrotron facility.
The experimental approach combining X-ray reflectivity (XRR) and grazing Incidence X-Ray Fluorescence (GIXRF) provide compositional and structural information on the analyzed samples.
THE GONIOMETER CASTOR
Dr Yves Ménesguen completed his post-doctoral studies in electronics and optics and is a permanent member of staff at CEA-LNHB since 2009. He has been involved in X-ray spectrometry and in the applications of monochromatic X-ray sources. He has developed combined XRR-GIXRF analysis and is responsible for the dedicated CASTOR goniometer and its applications to characterize innovative materials.
Dr Marie-Christine Lépy is a research director at CEA and head of the photon spectrometry group at CEA-LNHB. She has developed X-ray spectrometry using tunable monochromatic X-ray sources. She is involved in several international committees and participated in the launch of the International Initiative on Fundamental Parameters.
