14 ATLAS Getting Ready for LHC
Inner Detector (ID)
The Inner Detector (ID) is organized into four sub-systems:
Pixels (0.8 108 channels)
Silicon Tracker (SCT)(6 106 channels)
Transition Radiation Tracker (TRT)(4 105 channels)
Common ID items
Physics at LHC, Cracow, 4-July-2006, P. Jenni (CERN)
15 ATLAS Getting Ready for LHC
Pixels
The Pixel project progresses well, but it was affected by two technical problem that require highest priority recovery actions:
Corrosion leaks in the barrel cooling tubes (now under control, repair ongoing)Broken low-mass cables for the barrel services (repair/replacement strategy being put into place)
At this stage the schedule is very tight and on the critical path, but all efforts are madeto have the full system ready for installation in time for May 2007
The installation schedule has been adapted as to accommodate the late availability (Note that the Pixel sub-system can be installed independently from the rest of the Inner Detector)
Two bi-staves assembled (final) in the L1 half-shell; L1 and L2 assembly proceed in parallel

Conclusions
Many important milestones have been passed in the construction, pre-assembly, integration and installation of the ATLAS detector components
Very major software, computing and physics preparation activities are underway as well, using the Worldwide LHC Computing Grid (WLCG) for distributed computing resources
Commissioning and planning for the early physics phases have started strongly
ATLAS is highly motivated, and on track, for first collisions in 2007
(ATLAS expects to remain at the energy frontier of HEP for the next 10 – 15 years, and the Collaboration has already set in place a coherent organization to evaluate and plan for future upgrades in order to exploit future LHC machine high-luminosity upgrades)
