The wiring of the spools are of different expansion coefficient than the leaders that are available for the power connection. Without having more info, I do suspect that the resistive connection are those connections between the actual magnet coils and the leads. My guess would be, to use Nickel-crome alloy which have a closer expansion/shrinkage coefficient when super cooled and will have a better bonding with the coils. It will be more costly, but it may have prevented this meltdown. The problem with the electrical connections

The failed magnet in the LHC was made by Fermilab, Illinois. Fermilab is still the largest functioning particle collider... unttil the LHC goes online. Conspiracy Theory, anybody? ;) just double checking my figures in my last post, I "discovered" something…

Because of LBJ, it was in Texas. When Bill Clinton became president he put a stop to it and had it filled in. How did that compare with the CERN/LNC ?" It would have been the SSC - it would have been more than three times the length of the LHC (87 km, as opposed to 27) and packed almost three times as much power (20 TeV, as opposed to 7)) Dan Tillmanns asks:

If they spend a year and multi-million amounts in repairs just for having it blown up again after a few hours, and if they do it without looking for ways to avoid/limit such incident again, then it looks just like an immense wasting of money. However, I suppose they do look at the root of the problem too, but am rather surprised not reading about it in the report.
