The Stripping Method for X‐Ray Spectral Correction in ISO 4037‐1 Narrow Spectra Series (N10‐N150)

X-Ray Spectrometry, EarlyView.
ABSTRACT Spectrometry is an important tool for the characterization of X‐ray beams in ionizing radiation metrology. However, the use of solid‐state spectrometers for accurate measurements requires correction of spectral distortions caused by the interaction between photons and the detector.

Simultaneous very small angle and small‐angle neutron scattering measurements enabled by flat‐panel‐type photomultiplier detectors at SANS‐J, JRR‐3

Journal of Applied Crystallography, EarlyView.
Replacing conventional position‐sensitive photomultiplier tube detector systems with a square array of four flat‐panel‐type photomultiplier tube detectors enables simultaneous very small angle and small‐angle neutron scattering measurements, while improving the effective neutron detection area, spatial resolution, sensitivity and signal‐to‐background ...

Experimental observation of grazing‐incidence X‐ray back‐diffraction with large angular dispersion

Journal of Applied Crystallography, EarlyView.
The first experimental observation of grazing‐incidence X‐ray back‐diffraction validates both the dynamical description and a simple geometrical interpretation of its exceptionally large angular dispersion.We report the first experimental observation of grazing‐incidence X‐ray back‐diffraction (GIXBD) exhibiting exceptionally large angular dispersion ...

Design and performance of a capacitor‐based burn‐through monitor for high‐power X‐ray beams at XFEL facilities

Journal of Synchrotron Radiation, EarlyView.
We present the results of testing 92 prototypes of a capacitor‐based burn‐through monitor at the LCLS XCS and XPP endstations. We quantify the beam energy density thresholds required to induce a detectable high‐voltage electrical short prior to complete burn‐through and demonstrate the reliability of this scalable, low‐cost solution for machine and ...

Development of a wide field of view X‐ray imaging detector and its application in X‐ray multi‐scale imaging

Journal of Synchrotron Radiation, EarlyView.
A wide field of view X‐ray imaging detector has been developed, and applied to wide‐range X‐ray multi‐scale imaging to visualize a relatively large object from its entire structure to the cellular level.A wide field of view X‐ray imaging detector with an effective field of view of more than 90 mm has been developed.

Diamond compound refractive lenses for high‐energy dark field X‐ray microscopy

Journal of Synchrotron Radiation, EarlyView.
In this work, we compare and quantify the performance of compound refractive lenses fabricated from single‐crystal diamond against conventional beryllium and aluminium counterparts under bright‐field conditions and show dark‐field imaging applications for the diamond compound refractive lens.Compound refractive lenses (CRLs) are a type of X‐ray optics ...

State of the Field: Royal Studies and Court Studies

History, EarlyView.
Abstract Monarchy, as the world's oldest and most enduring form of political organization, is an area that has attracted the attention of scholars from a range of disciplines. Two connected and complementary fields embody this interdisciplinary study of monarchy and monarchies: royal studies, which takes an all‐encompassing approach to monarchy, and ...
