Summary
This materials science study addresses energy loss mechanisms in high-temperature superconductor tapes designed for large-scale magnetic systems in particle accelerators and fusion tokamaks. The authors demonstrated that existing theoretical models inadequately predicted coupling loss in filamentized REBCO tapes produced via industrial deposition methods, and proposed an improved model enabling quantitative predictions across low- to mid-frequency ranges without empirical parameter adjustment. The work represents an advance in superconductor engineering applicable to high-energy physics infrastructure.
UK applicability
This research is not directly applicable to UK agricultural, soil, or food systems research. It may be of tangential interest to UK institutions operating particle accelerators or conducting fusion research (such as the Culham Centre for Fusion Energy), but falls outside the scope of farming systems and human nutritional health.
Key measures
Hysteresis loss, coupling loss, magnetic field frequency response (up to 1000 Hz), filament geometry parameters
Outcomes reported
The study evaluated hysteresis and coupling loss in filamentized REBCO (rare-earth barium copper oxide) superconductor tapes produced via scalable industrial deposition on patterned Hastelloy substrates. The researchers developed an improved quantitative model for predicting coupling loss at frequencies up to 1000 Hz without requiring geometric parameter fitting.
