Plans to begin smashing particles at the Large Hadron Collider (LHC) may be delayed after a magnet failure forced engineers to halt work.

The failure, known as a quench, caused around 100 of the LHC's super-cooled magnets to heat up by as much as 100C.

Hmmm... et tonn helium... Sabotasje? Eller bare en gjeng forskere som spiller live rollespill, "Donald Duck og protonstrålen"?
