The Critical-Current Envelope
The map of how much current REBCO carries across field and temperature — the magnet's operating boundary.

A superconductor's critical current falls as field and temperature rise, tracing a critical surface. Magnet design keeps operation safely inside it with margin. Reaching 16.84 T and 26.49 T means operating REBCO near the high-field frontier of that envelope, which the REBCO study maps explicitly.
Common questions
The surface, falling with field and temperature, above which a superconductor quenches to normal resistance. Magnets operate safely inside it with margin.
Because reaching the breeder's and burner's fields means working near the REBCO high-field frontier, so Kronos maps the envelope openly (DOI 10.5281/zenodo.21842514) rather than assuming comfortable margin.
