That's not to mention delays in work too. Every time there's a "quenching" event at the LHC, that's days/weeks/months fixing everything and getting it back down

That's not to mention delays in work too. Every time there's a "quenching" event at the LHC, that's days/weeks/months fixing everything and getting it back down to temp. I seem to recall they had to shut down for a year or so for upgrades at one point too. Having to work around the cooling had to have affected that timeline.
