Abstract
The ISAC RF system consists of a radio frequency quadrupole accelerator, five drift tube LINACs, six bunchers, two choppers, and a bunch rotator. An additional buncher will be added in the near future. They run at frequencies ranging from 5.89 to 106.08 MHz, and have cavity Q values ranging from 400 to in excess of 5000. All have to run synchronously and be individually amplitude and phase regulated. A novel system that provides closed-loop amplitude, phase, and tuning control for each cavity using a single feedback circuit is employed. This system, as well as the frequency synthesis and distribution system, is described in this paper.

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
