Precision work is performed on the semiconductor tracker barrel of the ATLAS experiment, on November 11, 2005. All work on these delicate components must be performed in a clean room so that impurities in the air, such as dust, do not contaminate the detector. The semiconductor tracker will be mounted in the barrel close to the heart of the ATLAS experiment to detect the path of particles produced in proton-proton collisions.
The huge ATLAS Toroid Magnet End-Cap A is transported between building 180 to ATLAS point 1 on May 29, 2007.
Lowering of one of the two ATLAS muon small wheels into the cavern, on February 15, 2008. The tunnel runs as deep as 175 meters (574 ft) underground.
View of the Compact Muon Solenoid cavern with its impressive dimensions: 53 meters long, 27 meters wide and 24 meters high.
A major milestone in the assembly of the ATLAS experiment's inner detector. The semiconductor tracker (SCT) and transition radiation tracker (TRT) are two of the three major parts of the ATLAS inner detector. Together, they will help determine trajectories of particle collisions produced when the LHC is switched on. February 22, 2006.
he electromagnetic calorimeter, completely assembled, is a wall more than 6 m high and 7 m wide, consisting of 3,300 blocks of scintillator, fibre optics and lead. This huge wall will measure the energy of particles produced in proton-proton collisions at the LHC when it is started in 2008. 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. May 17, 2005.
