Improvement of the Efficiency of the TRIUMF Charge State Booster (CSB)
Bibliographic record
Abstract
The Electron Cyclotron Resonance Ion Source (ECRIS) is a versatile and reliable ion source to charge-breed rare isotopes at the TRIUMF’s Isotopes Separation and Acceleration (ISAC) facility. Significant research work has been done by different groups worldwide to improve the efficiency and performance of the ECRIS. The most recent result of these activities is the implementation of the two-frequency plasma heating. At the ISAC facility of TRIUMF, a 14.5 GHz PHOENIX booster which has been in operation since 2010 was recently upgraded to accommodate the two-frequency heating system using a single waveguide to improve its charge breeding efficiency. Besides, a program has been launched to improve and optimize the extraction of charge bred isotopes in terms of beam emittance. A detailed investigation of the effect of the two-frequency heating technique on the intensity, emittance, and the efficiency of the extracted beam is presently being conducted and the status will be presented.

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.
