Powering of the CMS Phase-2 Upgraded Tracker
/ Cassese, Antonio (INFN, Florence)
/CMS Collaboration
The LHC machine will be upgraded to increase its peak luminosity and targeting an integrated luminosity of $3000 \div 4500\;$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..

Prototyping of Hybrid Circuits for the CMS Phase-2 Outer Tracker Upgrade at the HL-LHC
/ Blanchot, Georges (CERN) ; Gadek, Tomasz (Zurich, ETH) ; Honma, Alan (Brown U.) ; Kovacs, Mark Istvan (CERN) ; Rasevic, Nikola (VINCA Inst. Nucl. Sci., Belgrade) ; La Rosa, Alessandro (CERN) ; Zografos, Angelos (Natl. Tech. U., Athens)
High Density Interconnect hybrids are being developed for the CMS tracker Phase-2 upgrade for the HL-LHC. These hybrids are flexible circuits laminated to carbon fiber composite stiffeners and are assembled with flip-chips, passives and connectors. [...]

Commissioning and simulation of CHROMIE, a high-rate test beam telescope
/ Asenov, Patrick Asenov (Democritos Nucl. Res. Ctr.)
/CMS Collaboration
The upgrade of the LHC to the High-Luminosity LHC (HL-LHC) is expected to increase the current instantaneous luminosity by a factor of 5 to 7, providing the opportunity to study rare processes and measure precisely the standard model parameters. To cope with the increase in pile-up (up to 200), particle density and radiation, CMS will build new silicon tracking devices with higher granularity (to reduce occupancy) and improved radiation hardness.

CMS Inner Tracker Upgrade
/ Luukka, Panja (Lappeenranta U. Tech.)
The LHC is preparing an upgrade, which will bring the luminosity of the machine to 5-7 $\times$ $10^{34}$~$\mathrm{ cm^{\text{-}2}s^{\text{-}1} }$ reaching an integrated luminosity of 3000 $\mathrm{ fb^{\text{-}1} }$ by the end of 2037. This High Luminosity LHC (HL-LHC) scenario will require extensive upgrades to the experiments to fully exploit the physics potential of the accelerator. [...]

Bringing heterogeneity to the CMS software framework
/ Gutsche, Oliver (Fermilab)
/CMS Collaboration
The advent of computing resources with co-processors, for example Graphics Processing Units (GPU) or Field-Programmable Gate Arrays (FPGA), for use cases like the CMS High-Level Trigger (HLT) or data processing at leadership-class supercomputers imposes challenges for the current data processing frameworks. These challenges include developing a model for algorithms to offload their computations on the co-processors as well as keeping the traditional CPU busy doing other work. [...]
