Abstract
A high-intensity 30-MeV H/sup -/ cyclotron has been constructed for NORDION International to be used for radioisotope production at the TRIUMF site. It is a four-sector radial ridge design with two 45 degrees dees in opposite valleys. An external multi-cusp DC ion source generates the beam for axial injection into the cyclotron. Two multiple-foil stripping mechanisms produce two simultaneous beams, each of intensities up to 250 mu A. First beam was achieved on May 9, 1990. The initial acceptance tests were completed on July 20, 1990, finishing the project within the 19-month construction schedule. Since then the machine has been used for regular isotope production and operator training.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

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
