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

10/26/2005And the end-caps are coming soon… here the LAr end-cap C on its way (22nd September)

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.)

Search for the Higgs Boson• Vector boson fusion

dominates favoured Higgs mass range

• Relies on calorimeter tagging forward jets

• Extensive VBF studies performed by Canadian group (including 2 theses)

• WW l l analysis performed by Canadians at Fermilab
