I wonder if it’s to avoid thermal expansion, and maybe fatigue related to cycling of expansion and contraction.
Yeah, it's probably not good to let your miles and miles of superconducting magnets get warm and expand, even slightly. At the scale of the LHC you're probably looking at meters of displacement across the whole structure.
