NSLS-II Digital RF Controller Logic and Applications
Bibliographic record
Abstract
The National Synchrotron Light Source II accelerator consists of the Storage Ring, the Booster Ring, and Linac along with their associated cavities. NSLS II is committed to the use of digital RF controllers for controlling these cavities. Given the number, types and variety of functions of these cavities, we sought to limit the logic development effort by reuse of parameterized code on one hardware platform. Currently we have fielded six controllers in the NSLS II system. There are two controllers each in both the Storage ring and Booster. The first controller in each is used to control the cavity field and the second controller used for diagnostics. In the Linac a controller is provided which modulates the eGUN grid to generate the bunches. Lastly, in the Master Oscillator Distribution System a controller is used to make phase corrections to the outgoing master oscillator clock signal to account for thermal phase drifts along the distribution path.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
