Characterization of a two-channel, high resolution hard X-ray microscope using Fresnel zone plates for laser-plasma interaction experiments

New X-ray imaging techniques are currently being developed at the 'Commissariat a l'energie atomique et aux energies alternatives' in the context of Inertial Confinement Fusion. Fresnel zone plates (FZPs) are being considered as they can perform high-resolution and high-flux imaging in the X-ray domain. Here we present the characterization of a bi-lens FZPs resolution used in an imager prototype, designed for the LULI2000 laser facility. Characterization was performed on a synchrotron radiation facility and on a femtosecond laser facility. The resolution of the two FZP channels was measured to be between 2.4 #mu#m and 5.2 #mu#m and the expected total resolution for the diagnostic was to be 3.3 #mu#m. (authors)
