Description

The high-luminosity upgrade of the LHC (HL-LHC) is foreseen to reach an instantaneous luminosity a factor of five to seven times the nominal LHC design value. The resulting, unprecedented requirements for background monitoring and luminosity measurement create the need for new high-precision instrumentation at CMS, using radiation-hard detector technologies. This contribution presents the strategy for bunch-by-bunch online luminosity measurement based on various detector technologies. The potential of the exploitation of the tracker endcap pixel detector, the outer tracker, the hadron forward calorimeter, the barrel muon detectors and the 40 MHz scouting system is discussed together with the concept of a standalone luminosity and beam-induced background monitor using Si-pad sensors.
