Abstract

fetched live from OpenAlex

The sections of beam pipe passing through the magnets of the two fast cycling synchrotrons of the KAON Factory accelerator are to be constructed of alumina, thereby avoiding the eddy current problems which would otherwise arise if conventional metal pipes were used. An RF shield is required inside the nonconducting ceramic pipe to provide a low-impedance path for the image current of the circulating beam. Two schemes using different construction techniques for both the ceramic pipe and the internal RF Shield are described and compared. It is noted that the reference design of alumina beam pipe plus RF shield has operated reliably on ISIS for over seven years and can be regarded as a proven design. It is concluded that the integrated design could, with a little more development, offer an alternative at lower cost.>

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.
