Sub-5 nm hard x-ray point focusing by the combination of a Kirkpatrick-Baez mirror and a multilayer zone plate

چکیده
In hard x-ray microscopy, one approach for point transmission focusing is the use of multilayer zone plates (MZP) instead of conventional Fresnel zone plates, which are difficult to prepare with high aspect ratio. In extension of our previous work on line focusing down to 6.8 nm using the combination of Kirkpatrick-Baez (KB) mirror and multilayer Laue lense (MLL) [1], we have here used the approach of a compound optics of a high gain KB mirror and a nanofocusing MZP at the coherence beamline P10 of Petra III. The basic concept is sketched in Fig.1.

Synchrotron-based imaging and tomography with hard X-rays
Hard X-ray imaging with synchrotron radiation is a powerful tool to study opaque materials on the microand nano-lengthscales. Different imaging methods are available with an instrument recently built at Sector 34 of the Advanced Photon Source. In-line phase contrast imaging is performed with micrometer resolution. Increased spatial resolution is achieved using cone-beam geometry. The almost par...

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 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 کامل2.B X-Ray Imaging with Kirkpatrick-Baez Microscopes
This article describes the design, testing, and use of Kirkpatrick-Baez (KB) x-ray microscopes on OMEGA. These microscopes consist of grazingincidence mirror pairs arranged to reflect and focus x rays, thereby providing images of the x-ray-emitting region. KB microscopes are one of several practical devices that can be used to focus and collect x rays. Simpler x-ray-imaging devices are the pinh...

The first test of nanoscale-focusing Kirkpatrick-Baez (KB) mirrors in the nested (or Montel) configuration used at a hard X-ray synchrotron beamline is reported. The two mirrors are both 40 mm long and coated with Pt to produce a focal length of 60 mm at 3 mrad incident angle, and collect up to a 120 µm by 120 µm incident X-ray beam with maximum angular acceptance of 2 mrad and a broad bandwidt...
