Performance of the university of saskatchewan compact torus injector with curved acceleration electrodes
Bibliographic record
Abstract
The first vertical compact torus (CT) injection experiment has been performed in the Saskatchewan Torus Modified (STOR-M) tokamak [Nucl. Fusion 46, 104 (2006)]. To increase the kinetic energy density of the injected CTs for deeper penetration, the University of Saskatchewan Compact Torus Injector (USCTI) was further modified by attaching a 90 degrees curved inner electrode coaxial with the outer electrode. The modification extended the original CT acceleration section from 60 to 114 cm. Effects of the curved acceleration electrodes on the velocity and magnetic field of the CT are reported in this paper. It has been found that the CTs, injected horizontally, were deflected to vertical direction and CT velocity measured at the curved acceleration section increased to 180 kms, representing a 40% increase compared with the case without the curved inner electrode in a previous experiment. At a higher acceleration bank voltage of 16 kV, this velocity increased to about 270 kms. In addition, amplification of the CT magnetic field in the curved acceleration section has also been observed.

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.
