The ALICE Inner Tracking System during its transport in the
experimental cavern and its insertion into the Time Projection Chamber (TPC).
ALICE (A Large Ion Collider Experiment @ CERN) will study the physics of
ultrahigh-energy proton-proton and lead-lead collisions and will explore
conditions in the first instants of the universe, a few microseconds after the
Big Bang. (Maximilien Brice, © CERN)

The LHCb electromagnetic calorimeter. This huge 6X7 square
meter wall consists of 3300 blocks containing scintillator, fibre optics and
lead. It will measure the energy of particles produced in proton-proton
collisions at the LHC when it is started. Photons, electrons and positrons will
pass through the layers of material in these modules and deposit their energy in
the detector through a shower of particles. (Maximilien Brice, ©

Aerial view of CERN and the surrounding region of
Switzerland and France. Three rings are visible, the smaller (at lower right)
shows the underground position of the Proton Synchrotron, the middle ring is the
Super Proton Synchrotron (SPS) with a circumference of 7 km and the largest ring
(27 km) is that of the former Large Electron and Positron collider (LEP)
accelerator with part of Lake Geneva in the background. (© CERN)
