Abstract

fetched live from OpenAlex

Polycrystalline chemical vapour deposition (pCVD) diamond detectors are being considered for an upgrade of Forward Calorimetry in the ATLAS detector at the CERN LHC. In order to determine their radiation hardness, four detectors were continuously monitored during irradiation with 500 MeV protons at TRIUMF to a fluence of 2.25 x 1017 protons/cm2. All four detectors worked at the end of the irradiation period. The detector response A as a function of fluence has been fitted to a sum of two exponentials and to a function A = ao/(1+a1ϕ) where ao is the initial response and ϕ is the fluence with a1 = 9.8 x 10−17 ± 3.2 x 10−18 cm2/proton. At the end of irradiation the response had reduced to five percent of the original value. The time resolution was found to be ∼ 250 picoseconds.

Full frame distilled prediction

Teacher imitation

Not 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.
