CLS Operational Status and Future Operational Plans
Bibliographic record
Abstract
The Canadian Light Source (CLS) has been in operation for users since 2005 and recently commissioned the 22^{nd} photon beamline. In 2021 the CLS commenced top-up operations at 220 mA, which has been a big success for the user experiments. The storage ring is now RF power limited and will require a second RF cavity to realise the design goal of 500 mA. The 250 MeV electron injector complex for the CLS booster synchrotron ring dates back to the original linac from 1962 and the Saskatchewan Accelerator Laboratory. This paper will give an overview of the present status of the accelerator systems for user operations and the operational improvement plans for a second RF cavity in the storage ring and a new linac.

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.
