We report on the development and test of a prototype track-finding processor for the Level-1 muon trigger of the Compact Muon Solenoid (CMS) experiment. The CMS experiment will study proton collisions at a center-of-mass energy of 14 TeV when the Large Hadron Collider begins operation in 2006. The Level-1 Trigger of CMS must reduce the 40 MHz beam crossing rate to approximately 100 kHz using custom electronic devices. The track-finding processor developed at the University of Florida reconstructs tracks in the endcap muon system of CMS, and reports the measured momentum of muon candidates to the Global Level-1 Trigger. The processor employs three-dimensional tracking algorithms to accommodate the non-axial magnetic field and high backgrounds in the CMS endcaps. A prototype processor was designed and built using programmable logic devices for flexibility, and successfully tested. The measured latency is only 400 ns for the decision logic. We also report on the plans for a pre-production prototype, as well as the overall physics capability of the endcap muon trigger.
