Hyperbolic X-ray Curved Crystal - XRD/XRF
Using a doubly curved crystal (DCC) provides three-dimensionally focused, highly monochromatic X-rays.
Introduction
Using doubly curved crystals (DCC), three-dimensionally focused, highly monochromatic X-rays can be obtained. Crystal materials such as mica, graphite, silicon, and germanium are applicable in the energy range of 1.5-58 keV. These crystals reflect X-rays based on Bragg's law of diffraction.
