We report on the development and test of a fast 3-D Track-Finder for the Level-1 trigger of the CMS endcap muon system. System tests included four types of custom circuit boards clocked at 40 MHz, optical links, and a high-speed custom auxiliary backplane in a VME crate. The hardware results, calculated using field-programmable gate arrays, programmable(More)
An open-access program for generating three-item statement (3TS) matrices from data such as molecular sequences does not currently exist. The recently developed LisBeth package allows for representation of hypotheses of homology among taxa or areas directly as rooted trees or as hierarchies; however, LisBeth is not a standard matrix-based platform. Here we(More)
The content of this note is intended for CMS internal use and distribution only Abstract We propose to fix the boundary between the DT and CSC Level-1 Track-Finders at η = 1.04. The ramifications of this decision and the details of the electronic interface between the two systems are discussed in this Note. The efficiency and ghost rate of the Track-Finders(More)
We report on the design and test results of a prototype processor for the CMS Level-1 trigger that performs 3-D track reconstruction and measurement from data recorded by the cathode strip chambers of the endcap muon system. The tracking algorithms are written in C++ using a class library we developed that facilitates automatic conversion to Verilog. The(More)
We report on the development and performance of a novel track-finding processor for the Level-1 trigger of the CMS endcap muon system. The processor links track segments identified in the cathode-strip chambers of the endcap muon system into complete three-dimensional tracks. It then measures the momentum of the best track candidates from the sagitta(More)
