The Track-Finding Processor for the Level-1 Trigger of the CMS Endcap Muon System
نویسنده
چکیده
The algorithms and hardware implementation of the Track-Finder for the CMS endcap muon system are described. The Track-Finder is implemented as 12 Sector Processors which identify up to the three best muons in 60 azimuthal sectors. The coverage in pseudorapidity includes the region of overlap with the barrel muon system. The track-finding algorithms are inherently 3-dimensional to achieve maximum background rejection. A 3-station sagitta measurement assigns pT to a precision similar to that achievable in the barrel region despite reduced magnetic bending in the endcap. The input to the Track-Finder is capable of collecting track segments from multiple bunch crossings, and the overall latency is expected to be about 350 ns.

A Prototype Track-finding Processor for the Level-1 Trigger of the Cms Endcap Muon System
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 threedimensional tracks. It then measures the momentum of the best track candidates from the sagitta measured between three muon chambers in the e...

The Cathode Strip Chamber (CSC) sub-detector [1] at the CMS experiment at CERN consists of trapezoidal 6layer chambers located in the Endcap regions. The CSC system is needed for precise muon identification and generation of trigger primitives for the Level-1 trigger system. The CSC triggering system comprises the onchamber anode and cathode electronics, the off-chamber boards housed in 9U crat...

متن کاملA Demonstrator for the ATLAS Level-1 Muon to Central Trigger Processor Interface (MUCTPI)
The Level-1 Muon Trigger Interface (MUCTPI) to the Central Trigger Processor (CTP) receives trigger information from the detector-specific logic of the muon trigger. This information contains up to two muon-track candidates per sector. The MUCTPI combines the information of all sectors and calculates total multiplicity values for each of six programmable pT thresholds. It avoids double counting...
