At the energies involved, it’s akin to a bacteria interfering with a supersonic goods train. The only bit that needs shielding is the detector systems, and that’s not THAT hard to do in space. At least if you’re at the point of building a space based accelerator.
I think on earth is preferential, and you’d have to build it underground anyways in order to shield it from interference.
Something something “resonance cascade.”
Even underground there is tons of issues. One for example is that the ground is having tides.
As the moon passes above is the ground is moving by several cm so it has to be compensated by the collider.
