    "abstract": "The pixel detector is the innermost tracking device of the CMS experiment at\nthe LHC. It is built from two independent sub devices, the pixel barrel and the\nend disks. The barrel consists of three concentric layers around the beam pipe\nwith mean radii of 4.4, 7.3 and 10.2 cm. There are two end disks on each side\nof the interaction point at 34.5 cm and 46.5 cm. This article gives an overview\nof the pixel barrel detector, its mechanical support structure, electronics\ncomponents, services and its expected performance.",
