Abstract

fetched live from OpenAlex

This paper introduces amorphous Selenium (a-Se) drift detectors with uniform drift field as a promising alternative to Silicon drift detectors in high-energy applications. A 3D model was created with a finite element method to simulate the electric field and potential for two detector designs that utilize microstrips and resistive collecting electrodes to increase spatial and energy resolution without increasing readout channels. The charge division readout technique is employed for 3D position sensing. The a-Se drift detector enables unipolar charge sensing for higher mobility carriers, resulting in higher temporal and energy resolution. Additionally, this detector design increases the detection area ratio and reduces the electronics noise, making it a cost-effective alternative with high energy resolution for large-area high-energy applications.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
