Quoting MadameConcorde (Reply 3): I hope they will have no more major breakdowns after the helium leaks and heated up magnets but who knows?
Don't worry about the helium leaks, this is just a plumbing problem (anyway, ALL helium systems leak, because helium atoms are so small that they can actually like hydrogen, diffund though the empty spaces in the cristalline structure of metals).

Such an ambitious project, one of the biggest, and next to the Apollo missions the biggest science project ever, surely needs to be done right, so I´m not surprised that repair will take its time. I´m only surprised that the failure happened so early during the testruns.

Quoting MD11Engineer (Reply 2): Well, those magnets are not mailorder items. They are unique pieces, made to customer specifications.
With the quench I assume that all coils inside have burnt through.
As far as I've heard it wasn't the actual coil but the connection between two coils which hadn't been soldered/welded well enough so it melted and ultimately arced. The coils themselves might actually have survived, but unless they've warmed the assembly up and looked inside we probably can't know for sure.
