Meter-Scale REBCO Tapes With a Current Flow Diverter Architecture
Bibliographic record
Abstract
The current flow diverter (CFD) architecture allows increasing the normal zone propagation velocity (NZPV) of rare-earth barium copper oxide (REBCO) tapes. A continuous reel-to-reel CFD fabrication process has been developed to produce a high quality one meter long CFD REBCO tape. Standard scratch tests showed that the adhesion strength of the silver layer of a regular commercial tape and an annealed CFD tape are similar while being slightly lower in the case of a nonannealed CFD tape. Depending on the CFD architecture, experimental measurements revealed an increase in the NZPV of CFD tapes by a factor of 6 to 22 with respect to regular tapes, which is comparable to previous results obtained on short length CFD tapes (12 cm). A detailed analysis combining optical microscopy and numerical simulations revealed that the reel-to-reel CFD fabrication process minimizes geometrical imperfections, which results in a good NZPV uniformity over long lengths. This demonstration of the effectiveness of the CFD concept in long-length CFD tapes represents an important step toward the potential development of a safe and more reliable protection scheme in high field magnets and other high current carrying REBCO based devices.

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.
