Hard x-ray nanoprobe based on refractive x-ray lenses

TLDR

The study aims to reduce the hard‑X‑ray beam size below 20 nm. A hard‑X‑ray scanning microscope using nanofocusing refractive lenses is being developed at ESRF ID13, capable of transmission, fluorescence, diffraction, and tomographic imaging with a 21 keV beam of 47 × 55 nm² size.

Abstract

Based on nanofocusing refractive x-ray lenses a hard x-ray scanning microscope is currently being developed and is being implemented at beamline ID13 of the European Synchrotron Radiation Facility (Grenoble, France). It can be operated in transmission, fluorescence, and diffraction mode. Tomographic scanning allows one to determine the inner structure of a specimen. In this device, a monochromatic (E=21keV) hard x-ray nanobeam with a lateral extension of 47×55nm2 was generated. Further reduction of the beam size to below 20 nm is targeted.
