Monochromatic X-ray backlighting imaging with toroidally bent crystal

The reflection type toroidally bent crystal analyzer was investigated based on the Bragg diffraction to diagnose the laser plasma X-ray. The dispersive element of crystal analyzer was mica. The bent radiuses of the crystal analyzer in meridian plane and in sagittal plane are 296 mm and 198 mm respectively, and the corresponding Bragg angle is 54°.
