Ptychographic characterization of a coherent nanofocused X-ray beam

Opt Express. 2020 Feb 17;28(4):5069-5076. doi: 10.1364/OE.386068.

Abstract

The NanoMAX hard X-ray nanoprobe is the first beamline to take full advantage of the diffraction-limited storage ring at the MAX IV synchrotron and delivers a high coherent photon flux for applications in diffraction and imaging. Here, we characterize its coherent and focused beam using ptychographic analysis. We derive beam profiles in the energy range 6-22 keV and estimate the coherent flux based on a probe mode decomposition approach.
