Iter and other big or old projects are going the safe route with magnets that need to be at 4 or so Kelvin. All these ‘hotter’ superconductors are relatively unproven (it’s a oversimplification for a broad category), especially their strength when made into the shapes that make the magnetic field and form part of the load bearing structure of the container. The winners would enter that tipping point.
- cma 6y agoIt is worth pointing out that Iter started in 1985, I think before REBCO was discovered (and it was a little bit after that they acheived superconductivity at 77K, liquid nitrogen temp). Sturdy and flexible tape form from ion beam-assisted deposition I think was later but I can't find the date. (edit: maybe in the lab in 1992? I'm not sure when it scaled production: https://en.wikipedia.org/wiki/Superconducting_wire#cite_note-20 https://en.wikipedia.org/wiki/Superconducting_wire#cite_note... )
- fabian2k 6y agoPractical use of the new high-temperature superconductors in high field magnets is even more recent. NMR is probably the closest commercial application for this kind of magnet, and the first spectrometers using the new superconductors were sold last year.
- Florin_Andrei 6y agoThe sandwich structure described in the article makes sense: separate the superconducting and the load-bearing functions into different layers.
