Abstract :
The ALICE Silicon Pixel Detector (SPD) forms the two innermost layers of the Inner Tracking System (ITS) of the ALICE experiment at LHC. The SPD is made of hybrid silicon pixel detectors with a total of 9.8 × 10 6 readout cells. The total material budget per layer is limited to less than 1% X 0 . The space and material budget constraints had strict implications on the design of the detector and the device packaging. An overview of the individual components of the SPD is presented as well as the status of production.
