My timing is impeccable. It appears that yesterday, scant hours after I wrote a post about explosive quenches of superconducting electromagnets, one of the ring magnets at the LHC quenched.
Interestingly, this magnet is of the same field strength, and therefore probably of similar construction, as the MRI machine I mentioned at the Martinos Center. However, the magnets at the LHC are much longer and narrower than an MRI machine, as the former needs to contain a miles-long beam of protons, while the latter needs to fit human patient comfortably.
I have a doubt…
