The x-ray emission in laser-plasma accelerators can be a powerful tool to understand the physics of relativistic laser-plasma interaction. It is shown here that the mapping of betatron x-ray radiation can be obtained from the x-ray beam profile when an aperture mask is positioned just beyond the end of the emission region. The influence of the plasma density on the position and the longitudinal...

a bionanocomposite film was developed by nanoclay incorporation to chitosan films, using a solution casting method and the effects of nanoclay concentration (0.5, 1.0, and 3% w/w) on the physical and mechanical properties of the chitosan films were evaluated. moreover, x-ray diffraction (xrd), scanning electron microscopy, and fourier transform infrared spectra (ftir) were used for studying mic...
Multiwavelength observations of SNR 1987A show that its morphology is rapidly changing at X-ray, radio, and optical wavelengths as the blast wave from the explosion expands into the circumstellar equatorial ring. Infrared emission arises from the interaction of dust grains with the hot X-ray emitting gas. We show that the IR emission provides important complementary information on the interacti...
X-ray scattering and interfacial tension measurements are used to demonstrate the formation of nanometer-thick aqueous films on aqueous bulk subphases from polymer-salt biphase mixtures. X-ray scattering determines a coupling constant that characterizes the coupled capillary wave fluctuations of the liquid-vapor and liquid-liquid interfaces of this thin film. These data also determine an effect...
During a severe accident in either sodium-cooled or water-cooled nuclear reactors, jets of molten fuel may impinge on the coolant resulting fuel-coolant interactions (FCI). Experimental programs are being conducted to study this phenomenology and support development models. Due optical opacity test section walls, sodium coolant, apparent water presence intense ebullition, high-speed X-ray imagi...
