Abstract
The T2K ND280 near detector will characterize the JPARC neutrino beam close to the production site, before any oscillation occurs. The Tracker section of this near detector is optimized for measurements of charged-current neutrino interactions and in conjunction with the surrounding electromagnetic calorimeter can also measure electromagnetic showers from neutral pion or single gamma production. The Fine Grained Detector, or FGD, provides an active target mass for these interactions. The FGD is composed of finely segmented plastic scintillators, which will allow for accurate tracking of short-ranged particles. Readout is accomplished using wavelength-shifting fibres coupled to multi-pixel photon counters and custom-built digitizing ASICs. The FGD also contains a water target, which will allow for the extraction of neutrino cross-sections on oxygen. This poster will focus on the expected capabilities of the FGD, as well as its ongoing construction and testing.

How this classification was reachedexpand
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; a candidate call from one teacher head, not a consensus.
