Efficient sub 100 nm focusing of hard x rays
An x-ray beam with energy of 20.5 keV has been efficiently focused down to a spot size as small as 90 nm390 nm by a Kirkpatrick–Baez reflecting mirrors device. The first mirror, coated with a graded multilayer, plays both the role of vertical focusing device and monochromator, resulting in a very high flux s231011 photons/sd and medium monochromaticity sDE /E,10−2d. Evaluation of the error cont...
متن کاملTwo-step hard X-ray focusing combining Fresnel zone plate and single-bounce ellipsoidal capillary.
A two-step focusing set-up combining a Fresnel zone plate with an ellipsoidal capillary is presented. It is shown that, in addition to the anticipated gain in flux, the employment of the prefocusing micro-optic makes optimal use of the elliptical shape of the capillary by almost eliminating aberrations. A small cross section of the prefocused beam allows a tiny fraction of the capillary surface...
متن کاملA Hard X-ray KB-FZP Microscope for Tomography with Sub-100-nm Resolution
An instrument for high-resolution imaging and tomography has been built at the APS beamline 34 ID-C, Argonne National Laboratory. In-line phase contrast tomography can be performed with micrometer resolution. For imaging and tomography with resolution better than 100nm a hard X-ray microscope has been integrated to the instrument. It works with a Kirkpatrick-Baez (KB) mirror as condenser and a ...
متن کاملTowards Sub-100 Nm X-ray Microscopy for Tomographic Applications
We have demonstrated that structures down to 150 nm can be visualized in X-ray projection images using a nano-focus X-ray source. Due to their unlimited depth of focus, they don a limit on the specimen size in the case of 3D tomographic imaging. Further simulation studies have shown that optimization of the detector response curve and switching from a reflective Xray target to a transmission ta...
متن کاملTextbook for hard X-ray focusing with Kirkpatrick-Baez optics
1. Background Currently, grand-scale synchrotron radiation facilities, where high-quality X-ray sources are available in wide energy ranges from the softto hardX-ray regions, have significantly advanced the performance characteristics of analytical technologies using the fluorescence, absorption and diffraction effects of X-rays in various materials. The application of X-ray microscopy with the...
