Description

The HL-LHC conditions of instantaneous peak luminosity up to 7.5x10^34 cm-2 s-1 and an integrated luminosity of the order of 300 fb^-1/year would result in 1 MeV neutron equivalent fluence of 2.3 x 10^16 neq/cm2 and a total ionizing dose (TID) of 12MGy (1.2 Grad) at the center of CMS, where its innermost component, the Phase-2 Pixel Detector will be installed. The detector should survive the above radiation dose, handle hit rates of 3GHz/cm^2 at lowest radius, be able to separate and identify particles in extremely dense collision debris, deal with a pileup of 140-200 collisions per bunch crossing and have high impact parameter resolution. This translates into a highly granular detector design with thinner sensors and smaller pixels, and a faster and radiation hard electronics compared to the Phase-1 counterpart. This presentation focuses reviews the Phase-2 upgrade of the CMS silicon pixel detector focusing on the features of the detector layout and on developments of pixel devices.
