Integration of the CMS Phase 1 Pixel Detector

During the extended year-end technical stop 2016/17 the CMS Pixel Detector has been replaced. The new Phase 1 Pixel Detector is designed for a luminosity that could exceed $\text{L} = 2x10^{34} cm^{−2}s^{−1}$. With one additional layer in the barrel and the forward region of the new detector, combined with the higher hit rates as the LHC luminosity increases, these conditions called for an upgrade of the data acquisition system, which was realised based on the $\mu$TCA standard. This contribution focuses on the experiences with integration of the new detector readout and control system and reports on the operational performance of the CMS Pixel detector.
