*_ABSTRACT_*

 

*            *The ATLAS pixel detector is the innermost detector of the 
ATLAS experiment at the Large Hadron Collider at CERN. With 
approximately 80 million readout channels, the ATLAS silicon pixel 
detector is a high-acceptance, high-resolution, low-noise tracking 
device. Providing the desired refinement in charged track pattern 
recognition capability in order to meet the stringent track 
reconstruction requirements, the pixel detector largely defines the 
ability of ATLAS to effectively resolve primary and secondary vertices 
and perform efficient flavor tagging essential for discovery of new physics.

 

               Being the last sub-system installed in ATLAS by the end 
of June 2007, Pixel Detector was successfully connected, commissioned, 
and tested in situ while meeting an extremely tight operations schedule, 
and is ready to take data upon the projected turn-on of the LHC at the 
end of 2009. UT Dallas group has successfully deployed and commissioned 
the environmental controls for the opto-links, crucial for stable 
operation of the readout electronics of the pixel detector. Since fall 
2008, the pixel detector was included in the combined ATLAS detector 
operation, collecting physics data with cosmic muons. Details from the 
pixel detector installation and commissioning, as well as the details on 
major calibration procedures and the results obtained with collected 
cosmic data, are presented along with the current ATLAS detector status 
summary.
