The AI Concierge: institutional design for recording, reconnection, and mutual growth at SPring-8-II

This Scientific Comment proposes the AI Concierge as an institutional design for recording and responsibly reusing tacit experimental judgments at synchrotron facilities. It specifies a minimum operational model that combines AI-assisted drafting with human confirmation, governance, provenance, and safeguards for knowledge reconnection.

High-purity X-ray polarimetry at high energies for Mössbauer spectroscopy

This work extends high-purity X-ray polarimetry into the 15–30 keV range, enabling polarization-filtered synchrotron Mössbauer spectroscopy of higher-energy nuclear resonances. A proof-of-principle experiment at 22.494 keV demonstrates a polarization purity of (1.2 ± 0.5) × 10⁻⁸, establishing the feasibility of the approach.

XAS3DLive: an interactive X-ray absorption spectroscopy simulation/fitting platform for atomic 3D structure characterization

An interactive X-ray absorption spectroscopy (XAS) simulation/fitting platform for atomic 3D structure characterization integrates machine-learning-driven XAS simulation, 3D structure visualization and editing, and experimental XAS fitting into one unity for fast and user-friendly analysis.

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

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 personnel protection at high-power light sources.
