This study optimizes a Diamond Light Source photon absorber using additive manufactured (AM; 3D printing) conformal cooling channels in copper, achieving a maximum temperature drop of 11%, pressure drop reduction of 82% and examination of the AM print quality and its compliance with synchrotron and particle accelerator hardware applications using custom benchmark artefacts. These improvements can reduce thermal fatigue failure, component size, vibrations and energy consumption of absorbers, boosting overall facility efficiency, reliability and beam stability.

We present an easily assembled, low-cost beam-tilting extension for synchrotron-based ultra-small-angle X-ray scattering (USAXS) / small-angle X-ray scattering (SAXS) beamlines enabling grazing-incidence (GIUSAXS) and transmitted (GTUSAXS) experiments on liquid surfaces with negligible loss of X-ray flux. The setup is implemented at the sample stage with ∼0.5 m of additional space and provides incidence angles up to ∼0.6°, corresponding to approximately twice the critical angle of typical reflector materials.

A versatile Mamba-based software framework for automated attitude tuning of beamlines is reported, which is expected to be able to cover most attitude-tuning needs (beam focusing, sample alignment etc.) in a simple and maintainable way. As well as a few real-world examples at the High Energy Photon Source and Beijing Synchrotron Radiation Facility, both in China, also presented is a virtual-beamline mechanism based on easily customisable simulated detectors and motors.

By coupling asymmetrical-flow field-flow fractionation to small-angle X-ray scattering (AF4–SAXS), we enable precise, size-resolved analysis of polydisperse samples. Our automated AF4–SAXS system at the EMBL P12 beamline streamlines workflows, making advanced characterization accessible to both novice and experienced users, with principles adaptable to other facilities.

The MUSTACHE setup, described in this work, provides a state-of-the-art approach for investigating phenomena induced by high-energy X-rays, specifically targeting deep-core ionization, Auger cascades, and molecular photofragmentation triggered by these processes. Optimized for the tender and hard X-ray range, this high-resolution electron–multi-ion coincidence setup enables efficient detection of high-kinetic-energy electrons and their correlated ions with high momentum resolution.
