The Drift Tube Track Finder MuonTrigger at the CMS Experiment

The Compact Muon Solid (CMS) is a general purpose experiment designed to study proton-proton collisions at the Large Hadron Collider (LHC). At the LHC, proton beams will cross each other at a rate of 40 MHz, producing in average 20 p-p interactions. The CMS L1 Trigger must select interesting collisions at a rate smaller than 100 kHz. This report describes in particular the CMS Drift Tube Track Finder (DTTF) Muon Trigger. The DTTF trigger motivation, electronic implementation, and expected performance are presented.
