Abstract
The dynamic modeling and control design of a newly proposed magnet power supply system are presented. This system is based on a conventional rectifier power supply with a series switch-mode ripple regulator (SMRR). It has been shown that this system offers excellent steady-state performance. A critical assessment of the dynamic performance of SMRR is presented here. Small signal dynamic models for the system are established. The function of the SMRR as a speed-up feedforward path during dynamic transients is analyzed. The regulator design criteria for the closed-loop system to achieve optimum performance are identified. The precise control of the magnet current can be achieved with several kHz regulation bandwidth and less than 10 ppm harmonic content. A systematic design procedure is outlined, and a design example is provided. Computer simulation and experimental results are presented to verify the theoretical analyses.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
