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.<br>

<p class="MsoNormal" style=""><span style=""> </span>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.</p>
