'Ring in the new...' for the CMS Detector

3 January 2001

The Compact Muon Solenoid (CMS) is already beginning to come together close to its final location at CERN, the European Laboratory for Particle Physics, Geneva. CMS is one of the two general purpose detectors being built for the Large Hadron Collider (LHC), the machine that will supersede the Large Electron Positron collider (LEP). Here we see the first complete ring of iron that will form part of the iron "barrel". The iron will contain the magnetic field created by a large superconducting solenoid, located within the barrel. The ring is about 15.8 m high (the yellow spot towards the lower right is an engineer's hard-hat - see here for a larger view). The LHC is scheduled for completion in 2005, and in the meantime visitors to CERN will have the chance to watch the progress of the CMS assembly.
