Deconstructing ALEPH

25 April 2001

After just over 11 years of service, the ALEPH detector at CERN, the European laboratory for particle physics is being dismantled, together with the other detectors that observed collisions at the Large Electron Positron collider, LEP. LEP was shut down in November 2001 to make way for a new machine, the Large Hadron Collider (LHC), which will be built in the same 27-km tunnel. This image, taken during the dismantling, makes plain the large scale of the detectors at LEP - notice the person emerging from the tunnel near the bottom of the picture.
