摘要：

Hard X-ray focusing by a linear phase Bragg-Fresnel crystal lens was performed with an efficiency close to 30%. The phase shift of an incident beam was controlled by deviating the crystal lens from the exact Bragg condition. Analytical expressions for the intensity and the image contrast at the focal point was presented.
