چکیده انگلیسی
The Silicon Pixel Detector (SPD) forms the two innermost layers of the ALICE Inner Tracking System (ITS). The SPD consists of 120 detector modules (half-staves) on two barrel layers at mean radii of 3.9 and 7.6 cm, respectively. The SPD contains in total nearly 107107 pixel cells which provides the high spatial precision, efficiency and granularity required to reconstruct secondary vertices of charm and beauty particle decays in a region where the track density could reach 80tracks/cm2.In this paper, the status of the construction and integration of the SPD are overviewed. Results on the detector performance with test beam data and results on the SPD performance with the response simulation model in the ALICE scenario are discussed.
