View of the CMS (Compact Muon Solenoid) experiment Tracker Outer Barrel (TOB) in the cleaning room. The CMS is one of two general-purpose LHC experiments designed to explore the physics of the Terascale, the energy region where physicists believe they will find answers to the central questions at the heart of 21st-century particle physics.

The Globe of Innovation in the morning. The wooden globe is a structure originally built for Switzerland 's national exhibition, Expo'02, and is 40 meters wide, 27 meters tall. (Maximilien Brice; Claudia Marcelloni, © CERN)
Assembly and installation of the ATLAS Hadronic endcap Liquid Argon Calorimeter. The ATLAS detector contains a series of ever-larger concentric cylinders around the central interaction point where the LHC's proton beams collide. (Roy Langstaff, © CERN)
Checks are performed on the alignment of the magnets in the LHC tunnel. It is vital that each magnet is placed exactly where it has been designed so that the path of the beam is precisely controlled. (Maximilien Brice, © CERN)
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.

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, © CERN)
