A method for obtaining self-standing bent monocrystals is proposed. The crystal curvature was interpreted and parametrized, while the crystallographic quality was verified using hard X-ray diffraction at the DIGRA facility (Institut Laue–Langevin, Grenoble, France).

Two perfect silicon mono-crystals were bent to be used to deflect high-energy charged particle beams in the context of beam extraction and/or beam collimation at accelerator facilities, such as for steering the 7 TeV proton beam of the Large Hadron Collider. The sample curvature and quality were tested at the ID11 beamline of the European Synchrotron Radiation Facility via hard X-ray diffraction and at the Karlsruhe Institute of Technology synchrotron via X-ray white-beam topography.
