Design and measurements of a damping ring kicker for the ILC
Bibliographic record
Abstract
The International Linear Collider (ILC) requires ultra fast kickers for the damping ring. The modulators must produce pulses of plusmn5 kV magnitude, with rise and fall times of 6 ns or less depending on the final configuration [1]. The deflector plates will be configured as a 50 Omega stripline, charged to opposite polarities, providing a potential difference of 10 kV. The pulse magnitude must be repeatable to a high accuracy. The need for 3.25 MHz burst mode operation, at 5 Hz, gives an average repetition rate of up to 16.3 kHz [2]. This paper describes a novel design for a pulse generator for the damping ring kickers, in which two stacks of 1 kV FETS will be combined to generate the fast pulses. Each stack of FETs is a 100 Omega driver: the two stacks form a 50 Omega pulse generator as this is preferable to one 50 Omega stack. Measurements and calculations are presented on the present state of the TRIUMF prototype pulse generator.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
