Abstract
The CLS presently has a 12 cell DBA lattice with a circumference of 170.88 m. By using conventional magnet designs an emittance of 18 nm-rad is achieved. Twelve 5 m straights are available for injection, an RF cavity and insertion devices. An emittance of 1 nm-rad (at 2.9 GeV) can be achieved replacing each DBAs with multi-bend achromats (MBAs) while preserving the 12-fold symmetry although with a reduction of the length of the straights. To achieve the strong focussing required for low emittance very strong field gradients are required in the dipoles as well as the quadrupole and sextupole magnets. Sufficient dynamic aperture for off-axis injection and Touschek lifetime may be possible.

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 it
