Glovebox-integrated XES and XAS station for <i>in situ</i> studies in tender x-ray region
Bibliographic record
Abstract
Abstract X-ray emission spectroscopy (XES), as a complementary technique to x-ray absorption spectroscopy (XAS), is powerful in the analysis of the electronic structure of the materials by probing the occupied density of states with high energy resolution. Recently, an XES spectrometer optimized for the tender x-ray region (2–5 keV) was successfully installed into an inert atmosphere glovebox, and the entire system was successfully integrated into the SXRMB (soft x-ray microcharacterization beamline) at the Canadian Light Source. Here, the technical design and the performance of the SXRMB XES-integrated glovebox station is presented. High energy resolution of ∼1 eV or better has been achieved for the spectrometer in the tender energy x-ray ranges. Capability of the station for in-situ XES and XAS measurements is demonstrated using an example of phosphorus phase transformation in phosphorus anodes for lithium-ion battery research.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
