OPPIS development at TRIUMF
Bibliographic record
Abstract
The TRIUMF OPPIS (Optically Pumped Polarized Ion Source) provides the precision quality beam for the experiment on parity-nonconservation in proton-proton scattering at 230 MeV beam energy. The results of recent developments and studies for the minimization of contributions to the experiment systematic error due to the beam energy and position modulations correlated with spin-reversal are presented. Studies of high current production have also been done in collaboration with INR, Moscow and BINP, Novosibirsk. The feasibility of a 10 mA polarized H/sup -/ ion current was demonstrated. The pulsed OPPIS application for the future RHIC and HERA polarization facilities are discussed. The polarization technique of the radioactive nuclide beam is proposed for beta-NMR condensed matter studies with a new ISAC facility at TRIUMF.

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 itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
