Abstract

fetched live from OpenAlex

Abstract We present the development of the front end amplifier circuit for the ABCStar readout ASIC designed for the upgraded ATLAS Inner Tracker (ITk) detector. The amplifier is intended to work with silicon strip sensors of moderate length between 1.9 cm and 5.5 cm dependent on position in the detector. The final circuit is implemented in a commercial 130 nm CMOS process tolerant up to the total ionizing doses (TID) predicted for the lifetime of the detector, that is maximum of 66 Mrad (660 kGy) (Si) for the endcap region. The final architecture and the performance of the circuit is presented in the context of a long development program which started soon after the construction of the present ATLAS Semi-Conductor Tracker (SCT) detector.

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.
