Abstract
The Sudbury Neutrino Observatory (SNO) [1] is a 1000 tonne heavy water Cerenkov detector, that has finished its data taking period on November 29th 2006. The heavy water was contained in a 12 m diameter acrylic sphere, surrounded by 9500 PMTs. It is located in INCOs Creighton mine in Sudbury, Ontario, Canada - 2039 m (6000 mwe) underground. The so-called third phase of the experiment had in addition to the heavy water an array of 36 3 He and 4 4 He proportional counters installed. In this configuration it can detect neutrons produced by the neutral current interaction of solar neutrinos by neutron capture in these counters (NCDs = neutral current detection array). This is a way to determine the neutral current flux independent of the PMT system with very different systematic uncertainties and is therefore determining the CC and NC reactions in separate streams.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
