Abstract

fetched live from OpenAlex

A high-power klystrode RF system for the RFQ1 facility at the Chalk River Laboratories has been manufactured by Continental Electronics corporation, Dallas using klystrode amplifier tubes developed by Varian, San Carlos. The system consists of two units, each capable of 250 kW in pulsed or CW mode. The two units can be operated independently to drive two separate accelerator structures, or together in a master/slave combination to drive one structure. This system is the first high-power klystrode to power a CW accelerator, and is a significant step in high-power klystrode development, increasing the average power per tube by a factor of 5 (to 250 kW). Commissioning, initial operation of one unit of this system with the RFQ1 facility, and data obtained to date, is described.>

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.
