Trigger performance of plastic scintillator detectors with silicon photomultiplier readout for cosmic ray muons
Bibliographic record
Abstract
Abstract A plastic scintillating fiber (SciFi) detector with multi-channel readout electronics based on the Citiroc1A chip is being developed for muon tomography application. In this study, to provide external triggers of cosmic ray muons to the SciFi detector, we fabricated two 10 cm × 10 cm × 2 cm plastic scintillators with wavelength shifting fibers (WLS) and evaluated their trigger performance with silicon photomultiplier readout. The results showed that the plastic scintillators embedded with WLS fibers obtained a light collection increase of up to three times in comparison to those without WLS fibers, and exhibited good discrimination of cosmic ray muons from ambient gamma rays. The trigger system consisted of the two scintillator detectors could achieve a high trigger efficiency up to 99% within a coincidence time window of 10 ns. Its inherent latency of both trigger strategy and readout electronics was well below 30 ns, making it feasible to offer external triggers to Citiroc1A with a peaking time tunable from 12.5 ns to 87.5 ns.

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.
