Defocused illumination with beam‐shaping condenser for uniform wide‐field X‐ray imaging

Journal of Synchrotron Radiation, EarlyView.
A defocused illumination method based on a beam‐shaping condenser to suppress fringe artifacts arising from rectangular aperture diffraction and sub‐grating interference is developed, providing an effective and practical approach for achieving wide‐field and uniform illumination in X‐ray microscopy.The beam‐shaping condenser (BSC) has become a key ...

Demonstration of a family of X‐ray dark‐field retrieval approaches on a common set of samples

Journal of Synchrotron Radiation, EarlyView.
This study aims to guide users of dark‐field imaging in selecting the most suitable technique for their imaging goals. To this end, we provide a summary table and highlight opportunities for future research into the sources of dark‐field contrast across emerging methods.There are various imaging setups capable of capturing dark‐field images, each with ...

A dedicated beamline for wide‐energy‐range X‐ray spectroscopy at SSRF: combining soft and hard X‐ray capabilities

Journal of Synchrotron Radiation, EarlyView.
A wide‐range beamline (130–10000 eV) combining both soft X‐ray and hard X‐ray photons has been constructed at SSRF for in situ X‐ray photoemission spectroscopy investigations of the solid–gas interface, and for hard X‐ray photoemission spectroscopy studies with layer‐by‐layer resolution.The advancement of renewable energy critically depends on the ...

Proposal of a novel APPLE‐KNOT undulator by selecting the KNOT field as the dominant magnetic field

Journal of Synchrotron Radiation, EarlyView.
The degradation of circular polarization state in conventional APPLE‐KNOT undulators has been noted. To overcome this limitation, we propose a novel APPLE‐KNOT undulator design which utilizes the KNOT magnetic field as the dominant component.The APPLE‐KNOT undulator forms composite magnetic fields by superimposing an APPLE field and a KNOT field with ...
