Description

The CMS experiment at the LHC at CERN is studying proton-proton collisions at a centre of mass energy of 13 TeV and a frequency of 40 MHz. The experiment produces a raw data rate of the order of PB/second and thus requires a highly efficient trigger system. This is achieved in two stages, a hardware trigger (Level-1(L1)) and a software trigger (High Level Trigger). The L1 trigger, selects interesting ‘physical’ events from the background of events by using calorimetric and muon information. The second decade of the LHC will experience an order of magnitude increase in the instantaneous luminosity, hence increasing the number of collisions per bunch crossing. Such an increase would require changes to both the algorithms and the architecture of the L1 trigger, in particular the integration of tracking at L1. The key component of the CMS upgrade for HL-LHC is a L1 Track Trigger (TT) system. The system will be able to identify tracks with a momentum threshold of 2 GeV/c or above. We will discuss about the concepts and usage for the L1 track finding system.
