Description
The CMS pixel detector is a tracking device located closest to the
interaction point. The present detector was designed for a maximum
luminosity of 1×1034 cm−2s−1. Following the Phase 1 upgrade of the LHC,
the peak luminosity is foreseen to reach 2×1034 cm−2s−1. Due to the
radiation damage and significant data losses in the readout chip, the
present pixel system must be replaced by a new one in order to maintain
the excellent tracking and physics performance of the detector. The main new features of the upgraded pixel detector would be ultra-light
mechanical design with four barrel layers and three end-cap disks,
digital readout chip with higher rate capability and new cooling system. These design improvements, along with results of simulation studies for the expected performance of the new pixel detector, and current status of the upgrade efforts will be presented.
