Description
The CMS pixel subdetector was upgraded at the beginning of 2017. CMS has seen a delivered integrated luminosity of 120 $fb^{-1}$, resulting in a fluence of $1 \times 10^{15} n_{eq}/cm^{2}$ received by the innermost layer of the Phase-1 pixel detector, after two years of operation in 2017-2018. Studies of radiation damage effects are essential to understand their implications on the detector operation as well as on its performance. The evolution of the detector properties, such as leakage current and depletion voltage, was studied during the data taking period. In this presentation we discuss the simulation of leakage current and depletion voltage in 2017-2018 for Phase-1 CMS pixel detector and compare it with the direct measurements of these parameters.
