A ug 2 00 5 The ATLAS Pixel Detector
The ATLAS Pixel Detector is the innermost layer of the ATLAS tracking system and will contribute significantly to the ATLAS track and vertex reconstruction. The detector consists of identical modules, arranged in three barrels concentric wi th the beam line and centered on the interaction point and three dis ks on either side for the forward region. The position of the Pixel Detector near the interaction point requires excellent radiation hardness, mechanical and the rmal robustness and good long-term stability, all combined witha low material budget. The detector layout, results from production modules and the status of assembly are presented.
Design studies on sensors for the ATLAS Pixel Detector
For the ATLAS Pixel Detector, prototype sensors have been successfully developed. For the sensors design, attention was given to survivability of the harsh LHC radiation environment leading to the need to operate them at several hundreds of volts, while maintaining a good charge collection efficiency, small cell size and minimal multiple scattering. For a cost effective mass production, a bias grid is implemented to test the sensors before assembly under full bias.
