CMS Detector experiment

To record the Universe’s tiniest constituents we need the world’s largest network of scientific instruments.

The 12,500-tonne Compact Muon Solenoid experiment (CMS) in Cessy, France, uses key information about particles emerging from high-energy collisions in the Large Hadron Collider (LHC) to unearth nature’s secrets.

A view through the heart of the CMS experiment

Taking on this challenge was a leap into the unknown with size, technical precision, innovation, durability, engineering and electronics like never before.

Even CMS’s method of construction was unique, with “slices” of detector weighing as much as 2000 tonnes being fully constructed on the surface then lowered 100 metres into the cavern, ready-made.
