Abstract
The storage ring for a 2.9 GeV Canadian Light Source has been designed. The lattice is composed of twelve compact DBA cells resulting in a ring that is 148 meters in circumference with twelve drifts of 4.5 meters for the inclusion of insertion devices. The emittance is less than 20 nm-rad, resulting in radiation brightness competitive with other "third generation" sources. Details of orbit correction, beam stability and lifetime and the effect of insertion devices have been investigated. The RF requirements have been defined and preliminary magnet designs have been done. The light source will operate with full energy injection and the injection scheme has been fully defined. Injection includes a 300 MeV linear accelerator, low energy transfer line, booster synchrotron and high energy transfer to the storage ring. With this configuration it will be possible to operate the storage ring with beam currents up to 500 mA, resulting in a source of very intense light over a broad range of photon energies. Far example, with a state of the art undulator, it will be possible to produce 20 keV photons with a brightness close to 10/sup 18/ photons/s/mm/sup 2//mrad/sup 2//0.1% bandwidth.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
