The Compact Muon Solenoid (CMS) is one of two main detectors at the LHC. It weighs 12,500 tons, measures 69 ft. (21 m) in length and is a key research tool for 2,000 scientists hailing from 37 countries. It was built above ground and lowered into place—a sensible strategy for so massive a piece of hardware. Here it is seen in 2008, just before it was completed.
