Abstract
The post-accelerator for the ISAC radioactive beam facility combines a 35.4 MHz RFQ and a variable energy 106 MHz DTL. The ISAC DTL is designed to accelerate ions with 3 /spl les/ A/q /spl les/ 6 to energies fully variable from 0.153 to 1.53 MeV/u. The unique separated function design allows efficient room-temperature acceleration and full energy variability with no degradation in beam quality. The first stable beams were accelerated in the DTL in Dec. 2000 with full commissioning in the first months of 2001. Test results with stable beams will be reported and compared with beam simulation results. In addition the initial operating experience with stable beam delivery is reported.

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
