Wavefront sensing at a high‐repetition‐rate X‐ray free‐electron laser

Journal of Synchrotron Radiation, EarlyView.
We demonstrate a fast, robust and sensor‐free approach to X‐ray speckle tracking that enables shot‐to‐shot wavefront characterization at high‐repetition‐rate X‐ray free‐electron lasers. Our measurements reveal a hierarchy of wavefront fluctuations indicative of instabilities in the accelerator and beamline optics at the European XFEL.Wavefront ...

A History of ‘Religious History’

Journal of Religious History, EarlyView.
As a category denoting the analysis of religious actors across history disinterestedly and on their own terms, “religious history” is a relatively recent coinage. This article offers a brief contextualisation of the emergence of the field in the twentieth century. It distinguishes “religious history” from an older, “confessional” mode of ecclesiastical

Soil wetting and drying processes influence stone artefact distribution in clay‐rich soils: A case study from Middle Gidley Island in Murujuga, northwest Western Australia

Archaeometry, EarlyView.
Abstract Soils that contain swelling clay minerals (e.g., montmorillonite) expand and contract during wetting and drying, causing movement within the soil profile. This process, known as argilliturbation, can alter artefact distributions, destroy stratigraphy and complicate the interpretation of archaeological deposits.
