  • 5 transmission electron microscopes
    Jéol JEM 1011 (100kV), Jéol JEM 1400 (120kV), Jéol JEM 1400 Flash (120kV), Jéol JEM 2100F (200kV, EDX,STEM), Jéol JEM ARM200F (200kV, EDX,STEM HAADF, EELS).

 

Services

As head of the microscopy department at the LCC, I ensure, for the LCC staff, the organization of all the work carried out at the Raimond Castaing microcharaterization center (scanning and transmission electron microscopy). I carry out all the specific work requiring high resolution, electronic diffraction, X-ray analysis, cartography, etc.
