CMS cavern inaugurated

1 February 2005

After six and a half years of work, CERN leaders and dignitaries celebrate the completion of a second detector cavern. The CMS cavern is 53 x 27 x 24 metres. To make space for the enormous detector, 250,000 cubic metres of soil have been removed from the detector cavern and a second space that houses technical components.
