Laser-driven plasma diagnostics commonly rely on high-resolution monochromatic x-ray imaging using α-quartz (211) spherical crystals at an 88.7° Bragg angle for the Cu Kα characteristic line. However, the performance of this imaging approach is constrained by astigmatism-induced resolution limits (&...
