Fact #159 Earth & tides

The ground tide stretches the LHC's 27-kilometre ring by about a millimetre over the course of a day, which is enough to shift the beam energy and has to be corrected for.

The crust under Geneva rises roughly 25 centimetres, and the tunnel goes with it. A circumference change of one part in twenty-seven million moves the beam energy by about 0.014%, so operators adjust the radio-frequency system to compensate. The Moon's pull is, quite literally, an entry in the collider's operating procedures.
