Powering of the CMS Phase-2 Upgraded Tracker

The LHC machine will be upgraded to increase its peak luminosity and targeting an integrated luminosity of 3000 to 4500 fb$^{−1}$ in 10 years. The CMS experiment will be upgraded to meet new challenges such as unprecedented radiation environment, demanding high resilience, and increased number of events per bunch crossing, requiring higher detector granularity. Consequently, both the Outer Tracker (OT) and Inner Tracker (IT) will have to fulfill very stringent requirements also in the power distribution to the front-end electronics: the OT (more than 13000 independent modules) will use in situ DC/DC converters to parallel distribute 100 kW of power, while the IT will use a serial powering scheme to provide about 50 kW to thousands of modular units.
