New Small Wheel Upgrade – Small Thin Gap Chamber Assembly, Testing, and Integration
Bibliographic record
Abstract
The small wheel is the innermost component of the muon endcap of the ATLAS experiment at CERN. It is currently being upgraded and replaced by a newer and more efficient model for the higher luminosity runs of the Large Hadron Collider (LHC). New wire chambers for triggering, nicknamed small-strip Thin Gap Chambers (sTGCs), are among the most important elements being enhanced in the New Small Wheel (NSW). The chambers are produced in various institutions worldwide, and then delivered to CERN for wedge assembly and testing. This paper gives a summary of the production chain used for the integration of sTGCs at CERN, with an emphasis on the testing carried out at the Gamma Irradiated Facility (GIF++) and long-term high voltage (HV) testing post-assembly.

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; both teacher heads agree on what is shown here.
