Chemistry applications at the Brockhouse sector hard X-ray beamlines at the Canadian Light Source
Bibliographic record
Abstract
The Brockhouse sector of the Canadian Light Source is a suite of three hard X-ray beamlines dedicated to X-ray diffraction (XRD) and scattering for materials science. The beamlines opened for general users during 2020–2021. Multiple experimental stations enable several techniques, including synchrotron high-resolution powder XRD, high-energy XRD, thin film characterization, total scattering for pair distribution function experiments, small-angle X-ray scattering, and in situ experiments with multiple environments. The Canadian chemistry community eagerly seized the new opportunities for in-depth structural characterization of materials, with applications in numerous research areas. In this manuscript, we showcase six different examples of how the Brockhouse sector has helped chemists in their unique research interests, offering a glimpse into the countless opportunities at our beamlines.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
