Description
The LHC machine is planning an upgrade program which will
smoothly bring the luminosity at about 5*10^34cm-2s-1 in 2028,
to possibly reach an integrated luminosity of 3000fb-1 by the
end of 2037. This High Luminosity LHC scenario, HL-LHC, will
require a preparation program of the LHC detectors known as
Phase-2 upgrade. The current CMS Tracker, including both inner
pixel and outer strip systems, is already running beyond design
specifications and will not be able to survive HL-LHC radiation
conditions. CMS will need a completely new device in order to
fully exploit the high-demanding operating conditions and the
delivered luminosity. The upgrade plan includes extending the
pixel detector in the forward region from the current coverage
of |\eta|<2.4 to 4, where up to ten disks will compose of the new
forward pixel detector. Additionally, the new outer system should
have also trigger capabilities. To achieve such goals, R&D activities
are ongoing to explore options and develop solutions that would allow
including tracking information at Level-1. The design choices for the
CMS Tracker upgrades are discussed along with some highlights of the
R&D activities.
