METHOD OF CONTROLLING WORKING SURFACE CURVATURE OF A SINGLE-CRYSTAL PLATE OF A DIFFRACTION UNIT WHICH PROVIDES COLLIMATION OF AN X-RAY BEAM Russian patent published in 2020 - IPC G21K1/06 

FIELD: physics.

SUBSTANCE: invention relates to X-ray optics and is intended to control the corresponding given convergence condition of the X-ray beam. Control is performed by curvature of working surface of monocrystalline plate in composition of diffraction unit formed by said plate, performing function of diffraction element, on which X-ray beam Bragg diffraction takes place and is glued to piezoelectric plate. Plate has flat electrodes sputtered on both its opposite surfaces to bend said monocrystalline plate together with the piezoelectric element plate when exposed to the last electric field.

EFFECT: technical result is the possibility of bending the working surface of the monocrystalline plate by further changing the curvature of the working surface of the monocrystalline plate by changing the value of the electric field strength acting on the piezoelectric element plate distributed along its surface, and providing simultaneous bending of glued to each other and cantilever fixed monocrystalline plate and plate of piezoelectric element.
