50 Tesla and Other Superconducting Possibilities
From
1. Charging superconductors will get a lot more efficient and cost effective
2. Superconducting magnets could achieve 50 tesla in about 5 years
3. Superconducting wire should cost about 4 times less on a price performance basis in three years
4. Superconducting motors should be in a few hundred or a few thousand vehicles by 2020
5. 50 tesla magnets should enable a muon collider in the 2020s
The Department of Energy recently funded Fermilab scientist Tengming Shen $2,500,000 to develop Bi2Sr2CaCu2Ox superconductors. He expects he could use this material to build magnets with a reach of up to 50 Tesla. Shen's magnets could potentially be cooled with a simpler refrigeration unit. The superconducting material that has magnetic field upper limits surpassing 100 Tesla at 4.2 K and can be fabricated into a multifilamentary round wire, to practical magnet conductors that can be used to generate fields above 20 Tesla for the next generation of accelerators.
Studies suggest that reducing the present cost of the superconductor by a factor of two would bring the cost of 10-GW, 1200-mile-long, superconducting cables to within range of that of conventional overhead lines. Since underground dc cables also offer substantial environmental, siting, and aesthetic benefits over conventional overhead transmission lines, they may become an attractive alternative option in some situations. Superpower Inc, is on track to improving price performance of its superconducting wire by 4 times.
