Abstract

fetched live from OpenAlex

An innovative optical module (OM) with segmented light-sensitive area has been developed for IceCube-Gen2 that will take neutrino astronomy at the South Pole to the next level. It builds on the successful features of the mDOM and D-Egg modules of IceCube Upgrade while adapting to the smaller borehole diameter of IceCube-Gen2. The newly developed OM, which is being tested in IceCube Upgrade, serves as a prototype for the planned mass production of about 10,000 OMs for IceCube-Gen2. To simplify the assembly process, important changes were made to the design, in particular to integrate the new gel pad concept. This replaces the 3D-printed support structure of the mDOM while maintaining through total internal reflection the increased light collection efficiency of the reflector rings. In addition, the design features local generation of high voltage for each photomultiplier tube (PMT) via a Cockcroft-Walton circuit and the full digitization of the signal on each PMT base with a sampling rate of 60 MSpS. This significantly reduces the complexity of the mainboard so that it fits into the limited space available. This article describes the development status and presents the performance of the first prototypes.

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.
