The last Barrel Toroid coil was moved into position on 25th August and the structure was released from the external supports on 29th September
10/26/2005 Insertion of the 3rd cylinder (out of the four) into the barrel SCT
All four barrel cylinders are complete and at CERN, the integration into the cylindrical support structure has been recently completed

ATLAS Barrel Calorimeter
The mechanical installation of the LAr and Tile Barrel Calorimeters in the pit has been completed end of 2004 on the support trucks below the access shaft on the C-side
The installation of electronics and services is ongoing, including also services for the ID
The Barrel Calorimeter is scheduled to move into the completed Barrel Toroid early November
In the meantime first cosmic ray events have been registered in part of the Tile Calorimeter asshow in the event display below

Very instructive comments from the user feedback have been presented at the recent ATLAS Physics Workshop (obviously this was one of the main themes and purposes of the meeting)

s = 14 TeV corresponds to E ~ 100 PeV fixed target proton beam
The LHC will be the first machineable to explore the high-E part of the cosmic ray spectrum
Are there links with astrophysics and cosmology ? Yes, many ….

First ATLAS PhysicsCalorimeter-based analyses
• Expect calorimeters to be in relatively good shape compared to other systems for first collisions
• Some high-profile analyses rely on the jets plus missing transverse energy signature e.g.
– Search for dark matter candidate (lightest, stable, supersymmetric particle)– Large extra dimension scenario
• Other topics: jets or em clusters e.g.– Search for high-mass resonances (Z’,W’,excited leptons,
etc.)
