摘要：

Bent Bragg-Fresnel lenses were tested under conditions relevant to the NRL Nike Laser monochromatic backlighting experiments. This hybrid two-dimensional (2D) x-ray imaging diagnostics incorporates high resolution and 1D focusing of the linear Fresnel structure as well as monochromatic and 1D focusing nature of cylindrically bent Bragg crystals. Lenses made of silicon (111) and quartz (10 (1) under bar1 and 10 (1) under bar0) with focal length of 125 rum were tested on our x-ray test bench. First images of backlit targets were obtained. Experimental issues, possible applications and future developments including extension of these diagnostics to the harder x rays (>10 keV), are discussed. (C) 2003 American Institute of Physics.
