If they have to keep the temperature down near liquid helium they must be using (and need) type I superconductors. If we get room temperature superconductors any time in the near future it will almost certainly be type II.
- vilhelm_s 9y agoWhat's the difference between them? When would you need one or the other?
- bradleyjg 9y agoTurns out I was wrong. These applications use niobium-titanium or niobium-tin, both of which are type II superconductors. They do have relatively low Tc -- 10-20 kelvins versus >80 kelvin for the best HTSC, and are cooled even lower to maximize the critical field and current (i.e. maximum they can withstand before losing superconductivity).
