CERN LHC Update: Large Hadron Collider Experiment Gets A Crucial Upgrade

The Compact Muon Solenoid (CMS) experiment is one of the four main experiments at the Large Hadron Collider (LHC) — the world’s largest particle accelerator, housed underground near the France-Switzerland border near Geneva. The experiment, which consists of a roughly 69 feet long and a 50 feet wide detector located 300 feet below the ground, was crucial in the discovery of the Higgs boson in 2012.
