Schematic representation of a Laue lens based on QM crystals. Left side: red arrows represent an X-ray beam diffracted towards a detector placed on the focal plane of the lens. The blue plate represents the crystal. The primary curvature leads to a secondary curvature of the planes affected by `quasi-mosaicity'. In this configuration, QM diffracting planes are orthogonal to the main surface of the plate. The primary curvature allows focusing of the diffracted radiation onto the focal plane, while the QM curvature increases the integrated diffraction efficiency. Right side: the particular arrangement of a QM crystal in a Laue lens. |
