The reflection type toroidally curved crystal analyzer is investigated based on the Bragg diffraction to diagnose laser plasma X-ray. The dispersive element of crystal analyzer is mica. The bent radiuses of the crystal analyzer in meridian plane and sagittal plane are 290 mm and 196 mm respectively, and the corresponding Bragg angle is 54°. The imaging experiment is carried out at the X-ray diffractometer facility by using Cr target. Two-dimensional monochromatic image of a mesh interval of 0.2 mm×0.2 mm is obtained by the toroidally curved crystal. The experimental result indicates that 2D monochromatic image with equal magnification in the meridian and sagittal planes can be obtained by using the toroidally curved crystal analyzer. Furthermore, the spatial resolution of the toroidally curved crystal analyzer achieves 67 μm when the size of the X-ray source is 500 μm and magnifying ratio is 1.86.
