Abstract
The ISAC project under construction at TRIUMF is to consist of radioactive ion sources, a high resolution mass separator, a low-energy (60 keV) experimental area, RFQ and DTL linacs to reach 1.5 MeV per atomic mass unit (amu), and a high-energy experimental area. Additionally, there will be a stable off-line source primarily for commissioning the linacs but also for use by the low-energy experimental program. The transport line which connects these elements therefore includes a switch which allows either the radioactive beam to supply the low energy area simultaneously with the off-line source supplying the RFQ, or the radioactive beam supplying beam to the RFQ simultaneously with the off-line source supplying beam to the low-energy experiments. The maximum ion source voltage is 60 kV. The RFQ accepts particles with 2 keV per amu, so masses less than 30 must have lower energy and masses larger than 30 can only be accelerated if they are multiply-charged.

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
