Description
The LHC is planning an upgrade program which will bring the luminosity to about $5\cdot 10^{34}$cm$^{-2}$s$^{-1}$ in 2028, with the goal of an integrated luminosity of 3000 fb$^{-1}$ by the end of 2037. This High Luminosity scenario, HL-LHC, will present new challenges of higher data rates and increased radiation. In order to maintain its physics reach in the HL-LHC era, the CMS Collaboration is preparing an upgrade program of the detector known as the Phase-2 upgrade. The CMS Phase-2 Pixel upgrade will require a high bandwidth readout system and highly radiation tolerant sensors and on-detector ASICs. Several technologies for the upgrade sensors are being studied. Serial powering schemes are under consideration to accommodate significant constraints on the system. These prospective designs, as well as new layout geometries that include very forward pixel discs with acceptance extended from |eta|<2.4 to |eta|<4, will be presented together with performance estimates.
