Level-1 Regional Calorimeter Trigger System for CMS
/ Authors
/ Abstract
The Compact Muon Solenoid (CMS) calorimeter regional trigger system is designed to detect signatures of isolated and nonisolated electrons/photons, jets, τ-leptons, and missing and total transverse energy using a deadtimeless pipelined architecture. This system contains 18 crates of custom-built electronics. The pre-production prototype backplane, boards, links and Application-Specific Integrated Circuits (ASICs) have been built and their performance is characterized.
