At 1127 (0927 GMT) on Friday, the LHC's online logbook recorded a quench in sector 3-4 of the accelerator, which lies between the Alice and CMS detectors.
The entry stated that helium had been lost to the tunnel and that vacuum conditions had also been lost.
It added that the Cern fire brigade had been called to the scene.
Maybe they've already succeeded in the future or a parallel reality?
