Abstract

fetched live from OpenAlex

The commissioning of the Advanced Rare Isotope Electron Linac (ARIEL) facility at TRIUMF is underway. The 30 MeV e-linac has successfully been commissioned to 100 W, and to further increase the power to 1 kW the beam loss monitor system (BLM) for fast Machine Protection must be fully operational. There are currently two types of BLMs employed in the e-linac; long-ionization chambers (LIC) and scintillators, consisting of a small BGO coupled to a PMT. A front-end beam loss monitor board was designed at TRIUMF to meet the strict requirements of the BLMs: a trip of the beam occurs on 100 nC in 100 ms of integrated beam loss, and the trip must occur in 10 us. This contribution will report on the status of the 1 kW BLM system commissioning and will give an outlook as the power is increased to the full 300 kW.

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.
