The ability to computationally transform coherent diffraction patterns into high spatial resolution images in coherent diffractive imaging (CDI) experiments at synchrotrons relies on the detection of weak signals of scattered photons. CDI techniques, such as X-ray ptychography, in the soft X-ray regime have been hampered by the challenging photon detection in this energy range. Nonetheless,...
The SoftiMAX beamline at MAX IV, commissioned in 2020, provides a versatile platform for soft X-ray spectromicroscopy and imaging in the 275–2500 eV range. The Scanning Transmission X-ray Microscopy (STXM) end-station, initially based on the ALS conceptual design with interferometric sample positioning, has since undergone extensive mechanical redesign and software optimisation to improve...
Two scanning transmission x-ray microscopes—MAXYMUS and MYSTIIC—are currently operated at undulator beamlines of BESSY II. Initial demonstrations of soft x-ray ptychography were previously conducted at MAXYMUS, successfully overcoming the resolution limits of conventional soft x-ray optics. However, these efforts were constrained by the limitations of 2D soft x-ray detector technology...
Soft x-ray imaging is a key method in the field of magnetism, offering exceptional spatial and temporal resolution, quantitative contrast, and the ability to investigate devices under operando conditions. Image contrast arises from strong dichroism at or near the elemental resonances. Coherent imaging is particularly attractive as it promises enhanced resolution and sensitivity. In this...
