MuscleX-Diffraction Imaging (MuscleX-DI) is an integrated, open-source software suite for data reduction and visualization of scanning X-ray diffraction (XRD) experiments. It is developed in Python and runs on Linux, Microsoft Windows or macOS. MuscleX-DI offers an end-to-end software analysis pipeline that ingests diffraction patterns and raster scan parameters to generate 2D visualizations of various calculated measurements from raw XRD patterns. Modules can be run via a graphical user interface or in a `headless mode' from the command line. We provide an overview of the general structure of the MuscleX-DI software package.

A new event-driven, energy-resolving ASIC intended for full-field X-ray fluorescence imaging is presented. Its frameless mode of operation was validated on a synchrotron beamline using a bump-bonded, 2D segmented silicon sensor, demonstrating per-pixel energy measurements with event-driven readout. Using on-chip spectral acquisition together with autonomous system control, this prototype establishes key building blocks for future real-time elemental mapping in biological, environmental and materials research.

The development of a timing diagnostic tool at the CSI endstation of the Shanghai Soft X-ray Free Electron Laser Facility achieves precise temporal characterization for advanced pump–probe experiments. The tool's unique design enables X-ray pulse monitoring without sample-stage rotation with both spectral-encoding and spatial-coupling methods, offering a reliable solution for X-ray pump–probe experiments at the CSI endstation.

A high-speed X-ray microscope design optimized for white beam synchrotron radiation enables real-time in situ imaging of crack dynamics during electron beam powder bed fusion (PBF-EB) of high-Z materials. With high temporal resolution and 10 µm spatial resolution, the system reveals previously unobservable crack evolution behavior in Ni-based superalloys, potentially advancing understanding of additive manufacturing processes.

MapsTorch is a new open-source package that enables automatic differentiation for X-ray fluorescence (XRF). The robust performance of MapsTorch makes it possible to automate steps that are usually manual in XRF analysis, including initial spectrum fitting and elemental intensity refinement, and therefore can support automated, high-throughput workflows for synchrotron facilities.

Comprehensive upgrades to optics, detectors and the endstation at the CXS beamline have transformed its coherent diffraction imaging performance, enabling routine Bragg coherent diffraction imaging and microbeam diffraction, and adding the capability for transmission geometry nano-imaging via ptychography.

A description of stereolithography printing a disposable, high-reliability alternative to commercially available stopped-flow capillary and cuvette holders is given. The new design offers all the advantages of rapid prototyping for enhanced design flexibility.

A four-segmented APPLE-II undulator was constructed, and its operation has started at NanoTerasu BL13U. The performance of arbitrary polarization control using phase shifters is demonstrated.

Here, a novel high-temperature contactless furnace, compatible with a range of X-ray diffraction and imaging techniques, is introduced. This study outlines its design, characterizes its thermal performance, and demonstrates strain relaxation and grain growth within an iron grain upon in situ annealing, utilizing dark-field X-ray microscopy at the ESRF-ID03 beamline.

A liquid-nitrogen-cooled silicon channel-cut monochromator was developed and tested under synchrotron radiation with incident powers up to 417 W. The minimal deformation and the maintained high stability indicate its suitability as a first optical element for fourth-generation synchrotron sources, such as SPring-8-II.

The refractory high-entropy alloy Mo0.20Nb0.21Ta0.19V0.20W0.20 crystallizes in a tungsten-type structure with all elements located on a single crystallographic site.

From whole specimens to histological level reconstructions, images derived from 3D synchrotron-based microtomography (SR-microCT) have emerged as a tool that is revolutionizing a wide range of biological research. This paper presents the first commissioning results from experiments to image the anatomy of small animals and specimens from zooarchaeology and palaeontology carried out on MOGNO, the nano- and microtomography beamline at Sirius/LNLS, Brazil.

A valence-band resonant inelastic X-ray scattering instrument, operating in the tender X-ray range, uses an incoming beam with a linear energy dispersion to reach the intrinsic resolution of the Rowland spectrometer. Such a scheme is insensitive to the incident bandwidth and therefore preserves count-rates despite the higher resolution.

Methods using spontaneous radiation to monitor and optimize the Aramis hard X-ray beamline are presented, together with the eight-year evolution of these improvements and the resulting record performance.

The Spanish synchrotron ALBA has recently inaugurated BL31-FaXToR, a beamline for hard X-ray micro-tomography. The design, performance and scientific program of the beamline are described.

Monochromators based on multilayer gratings can provide a very high throughput on an extended energy range (1 to 5 keV) in the tender X-ray domain. A multilayer mirror must be associated with the grating to achieve a fixed exit direction. We show how important an accurate modeling of the reflectivity of these two elements is to achieve both an optimal design and an optimal tuning.

A reactor is described, whose modular design enables in situ X-ray scattering and spectroscopy, infrared spectroscopy, gas and liquid injection under autoclave-like conditions and magnetic stirring for solvothermal synthesis up to 200°C and 8 bar.

An analysis of experimental artifacts in time-resolved X-ray solution scattering data acquired at high repetition rate XFEL sources, specifically at the FXE instrument at the European XFEL, is presented.

It has been 50 years since the publication in PNAS of our first results on the utilization and demonstrated benefits of synchrotron radiation for macromolecular crystallography. In this brief article, I offer some personal observations and comments about that early research at Stanford and the Stanford Synchrotron Radiation Project (SSRP, later renamed SSRL), how it evolved, and consider key factors in how and why synchrotron radiation ultimately catalyzed a new and transformational paradigm for study of the structure of biomolecules.

We provide a historical introduction and our thoughts on the current trends including some based on papers in this special issue of Journal of Synchrotron Radiation celebrating the 50th Anniversary of the Stanford SSRL synchrotron radiation and protein crystallography initiative led by Keith Hodgson.

This work provides guidelines on how to meaningfully perform a dip-and-pull X-ray photoelectron spectroscopy (XPS) experiment applied to electrochemistry and electrocatalysis to obtain information on both the electrode properties and the electrode/electrolyte interface. The aim is to facilitate access to the dip-and-pull XPS method to newcomers from the field of electrochemistry.
