Designing a toroidal crystal for monochromatic X-ray imaging of a laser-produced He-like plasma
文献摘要：
In this study,a toroidal quartz(2023)crystal is designed for monochromatic X-ray imaging at 72.3°.The designed crystal produces excellent images of a laser-produced plasma emitting He-like Ti X-rays at 4.75 keV.Based on the simulations,the imaging resolutions of the spherical and toroidal crystals in the sagittal direction are found to be 15 and 5 μm,respectively.Moreover,the simulation results show that a higher resolution image of the source can be obtained by using a toroidal crystal.An X-ray backlight imaging experiment is conducted using 4.75 keV He-like Ti X-rays,a 3×3 metal grid,an imaging plate and a toroidal quartz crystal with a lattice constant of 2d=0.2749 nm.The meridional and sagittal radii of the toroidal α-quartz crystal are 295.6 and 268.5 mm,respectively.A highly resolved image of the microgrid,with a spatial resolution of 10 μm,is obtained in the experiment.By using similar toroidal crystal designs,the application of a spatially resolved spectrometer with high-resolution X-ray imaging ability is capable of providing imaging data with the same magnification ratio in the sagittal and meridional planes.
