Summary
The silicon pixel detector is the innermost component of the CMS tracking system, providing high precision space point measurements of charged particle trajectories. Before 2018 the number of interactions per bunch crossing will significantly increase. To maintain a high tracking efficiency, CMS has planned to replace the current pixel system during Phase I by a new lightweight detector, equipped with an additional 4th layer in the barrel, and one additional forward/backward disk. A new readout chip has been designed, with increased data buffers and a digital readout protocol to increase the readout speed. The present status of the project will presented, including preliminary results from tests on the first production pixel modules of the new Pixel Tracker.
