Michel Mathieu, a technician for the ATLAS collaboration, is cabling the ATLAS electromagnetic calorimeter's first end-cap, before insertion into its cryostat. Millions of wires are connected to the electromagnetic calorimeter on this end-cap that must be carefully fed out from the detector so that data can be read out. Every element on the detector will be attached to one of these wires so that a full digital map of the end-cap can be recreated. Photo #: 001_001_001.jpg |

After the insertion of the first end-cap into this cryostat, the team proceed to the wiring operations. Millions of wires are connected to the electromagnetic calorimeter on this end-cap, whch must be carefully fed out from the detector so that data can be read out. The energy of photons, electrons and positrons will be measured as they pass through the end-cap having been created along the line of the beams in the proton-proton collisions. Photo #: 0308016_02 |

A view from inside the liquid-argon calorimeter end cap. The back of the rear HEC wheel. The brass plug 2 can be seen in the centre, circling the opening in which the FCAL assembly. At the outside can be seen the cryostat, and the pigtails coming from the feedthroughs. In the foreground, in green, is the T6 cradle on which the wheels were supported before insertion. At the 6 and 9 o'clock positions can be seen attached to the wheel the stainless steel sliders, and below them the rail that support the wheel. Photo #: atl-enews-2003-024_Figure_4.jpg |
