“…The results are encouraging but it remains technically difficult to produce bright X-ray point sources in order to reach the desired spatial resolution. As an alternative of X-ray point projection diagnostics, X-ray monochromatic backlighting imaging using spherically bent crystals is successfully applied nowadays (Belyaev et al, 1976;Pikuz et al, 1995Pikuz et al, , 1997Aglitskiy et al, 1998Aglitskiy et al, , 1999Koch et al, 1998Koch et al, , 1999Fraenkel et al, 1999;Workman et al, 1999;Sanchez del Rio et al, 1997;Sinars et al, 2003aSinars et al, , 2003bCuneo et al, 2005;Benuzzi-Mounaix et al, 2006;Le Pape et al, 2008). It has already been experimentally demonstrated that in the case of almost normal incidence in backlighting traditional scheme, spatial resolution around 1.6 mm could be reached within a field of view about1 mm (Aglitskiy et al, 1998) and about 10 mm within a bigger field of view (4 Â 20 mm 2 ) (Sinars et al, 2003a(Sinars et al, , 2003b.…”

An improved high luminosity, easily spectrally tunable backlighting scheme based on a spherically bent crystal is considered in this paper. Contrary to the traditional backlighting scheme, we used crystal far from normal incidence, and the backlighter source was inside the Rowland circle. With the presented configuration, we obtained a spatial resolution up to 8 mm in the desired direction with an X-ray backlighting energy close to 5 keV. Detailed discussions and ray-tracing calculations show that with this convenient scheme resolution down to 5 mm can be achieved. A dedicated application to high energy density physics is presented: the radiography of shock compressed matter.

Laser-driven shock waves studied by x-ray radiography

Multimegabar laser-driven shock waves are unique tools for studying matter under extreme conditions. Accurate characterization of shocked matter is for instance necessary for measurements of equation of state data or opacities. This paper reports experiments performed at the LULI facility on the diagnosis of shock waves, using x-ray-absorption radiography. Radiographs are analyzed using standard Abel inversion. In addition, synthetic radiographs, which also take into account the finite size of the x-ray source, are generated using density maps produced by hydrodynamic simulations. Reported data refer to both plane cylindrical targets and hemispherical targets. Evolution and deformation of the shock front could be followed using hydrodynamic simulations.

“…Though laser-driven X-ray absorption radiography has been successfully demonstrated on many experiments (some examples are reported in [14][15][16][17][18]), XPCI using laser-produced X-ray sources has been less intensively studied. A significant advance in the application of laserdriven bremsstrahlung X-ray sources to XPCI was shown by Workman et al in 2010 [19], however the quality of the images they obtained did not allow for a comprehensive study of shock wave characteristics.…”

X-ray phase-contrast imaging (XPCI) is a versatile technique with wide-ranging applications, particularly in the fields of biology and medicine. Where X-ray absorption radiography requires high density ratios for effective imaging, XPCI is more sensitive to the density gradients inside a material. In this letter, we apply XPCI to the study of laser-driven shockc waves. We used two laser beams from the Petawatt High-Energy Laser for Heavy Ion EXperiments (PHELIX) at GSI: one to launch a shock wave and the other to generate an X-ray source for XPCI. Our results suggest that this technique is suitable for the study of warm dense matter (WDM), inertial confinement fusion (ICF) and laboratory astrophysics.
