Bragg x-ray optics based on crystals with transmission and reflection properties bent on cylindrical or spherical surfaces are discussed. Applications of such optics for obtaining one- and two-dimensional monochromatic images of different plasma sources in the wide spectral range 1-20 Å are described. Samples of spectra obtained with spectral resolution of up to λ/Δλ ~ 10,000 and spatial resolution of up to 18 μm are presented.

We report the use of streaming data interfaces to perform fully online data processing for serial crystallography experiments, without storing intermediate data on disk. The system produces Bragg reflection intensity measurements suitable for scaling and merging, with a latency of less than 1 s per frame. Our system uses the CrystFEL software in combination with the ASAP::O data framework.

After the publication of "Direct formation of hard-magnetic tetrataenite in bulk alloy castings" Ivanov et al., Advanced Science 10 (2022) 2204315, the authors identified a potential misinterpretation of the experimental data. Further work confirms that the original conclusions cannot be supported, and accordingly the paper is retracted.

Article Synopsis
- - The study compares the effectiveness of two types of X-ray analyzers: the spherically bent Bragg analyzer and the cylindrically bent Laue analyzer, focusing on their reflectivity and energy resolution using a SiO glass sample.
- - Bragg analyzers perform well at photon energies up to 10 keV but experience a decline in reflectivity and resolution as energy increases, particularly beyond 20 keV.
- - In contrast, Laue analyzers show improved reflectivity and steady resolution at energies over 10 keV, making them ideal for high-energy-resolution fluorescence-detection and X-ray emission spectroscopy of certain materials, with both analyzers demonstrating similar performance in specific measurements.

Article Synopsis
- A new real-time feedback system has been designed to enhance beam position and energy at the Shanghai Synchrotron Radiation Facility's hard X-ray nanoprobe beamline.
- The system separates the beam position signals into high-frequency and low-frequency components, which are corrected using two different types of optical components with varying inertial masses.
- Experimental results show a marked improvement in stability, reducing beam angular fluctuations significantly, from 2.21 to 0.92 µrad RMS horizontally and from 0.72 to 0.10 µrad RMS vertically.
Article Synopsis
- - The study presents a new processing strategy for synchrotron scanning 3D X-ray diffraction data to analyze complex materials like crystalline rocks, focusing on overcoming challenges of deformation and multiple phases in the samples.
- - The method utilizes Friedel pairs to accurately pinpoint diffraction events and employs new modules to match data, assign phases to pixels or voxels, and locally fit crystal orientations.
- - Tests on fractured granite and a metal gasket demonstrate the technique's ability to detail internal structures and textures, revealing valuable information about materials under high plastic deformation.
