A simulation framework for the CMS Track Trigger electronics
/ Amstutz, Christian (Karlsruhe U., EKP) ; Magazzu, Guido (INFN, Pisa) ; Weber, Marc (Karlsruhe U., EKP) ; Palla, Fabrizio (INFN, Pisa)
A simulation framework has been developed to test and characterize algorithms, architectures and hardware implementations of the vastly complex CMS Track Trigger for the high luminosity upgrade of the CMS experiment at the Large Hadron Collider in Geneva. High-level SystemC models of all system components have been developed to simulate a portion of the track trigger. [...]

The CMS High Level Trigger System: Experience and Future Development
/ Bauer, Gerry (MIT) ; Behrens, Ulf (DESY) ; Bowen, Matthew (CERN) ; Branson, James G (UC, San Diego) ; Bukowiec, Sebastian (CERN) ; Cittolin, Sergio (UC, San Diego) ; Coarasa, J A (CERN) ; Deldicque, Christian (CERN) ; Dobson, Marc (CERN) ; Dupont, Aymeric (CERN) et al.
The CMS experiment at the LHC features a two-level trigger system. Events accepted by the first level trigger, at a maximum rate of 100 kHz, are read out by the Data Acquisition system (DAQ), and subsequently assembled in memory in a farm of computers running a software high-level trigger (HLT), which selects interesting events for offline storage and analysis at a rate of order few hundred Hz. [...]

Track-Parameter Evaluation and Primary-Vertex Finding with the Pixel Detector
/ Cucciarelli, Susanna (Basel U.) ; Konecki, Marcin (Basel U.) ; Kotlinski, Danek (PSI, Villigen, Switzerland) ; Todorov, Teddy (Institut de Recherches Subatomiques, IN2P3-CNRS-ULP, LEPSI Strasbourg, France)
Two algorithms for primary-vertex finding based on charged particle tracks reconstructed with three pixel hits are presented in this note. The evaluation of the track parameters is also described. [...]

Recent experience and future evolution of the CMS High Level Trigger System
/ Bauer, Gerry (MIT) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Bukowiec, Sebastian Czeslaw (CERN) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; Coarasa Perez, Jose Antonio (CERN) ; Deldicque, Christian (CERN) ; Dobson, Marc (CERN) ; Dupont, Aymeric (CERN) et al.
The CMS experiment at the LHC uses a two-stage trigger system, with events flowing from the first level trigger at a rate of 100 kHz. These events are read out by the Data Acquisition system (DAQ), assembled in memory in a farm of computers, and finally fed into the high-level trigger (HLT) software running on the farm. [...]

An FPGA based track finder at L1 for CMS at the High Luminosity LHC
/ Amstutz, Christian (KIT, Karlsruhe, EKP) ; Ball, Fionn Amhairghen (Bristol U.) ; Balzer, Matthias Norbert (KIT, Karlsruhe, EKP) ; Brooke, James John (Bristol U.) ; Calligaris, Luigi (Rutherford) ; Cieri, Davide (Rutherford) ; Clement, Emyr John (Bristol U.) ; Hall, Geoffrey (Imperial Coll., London) ; Harbaum, Tanja Renate (KIT, Karlsruhe, EKP) ; Harder, Kristian (Rutherford) et al.
A new CMS Tracker is under development for operation at the High Luminosity LHC from 2025. It includes an outer tracker based on PT-modules which will construct tracker stubs, built by correlating clusters in two closely spaced sensor layers for the rejection of low transverse momentum track hits, and transmit them off-detector at 40MHz.

Further Tests of the CMS Drift Tubes Muon Trigger
/ Aldaya, M ; Amapane, Nicola ; Battilana, Carlo ; Bellato, Marco ; Benvenuti, Alberto ; Bontenackels, Michael ; Castellani, Lorenzo ; Cavallo, Francesca Romana ; Cerminara, Gianluca ; Checchia, Paolo et al.
Two drift tubes stations of the CMS muon barrel system were exposed, in October 2004, to a 40 MHz bunched muon beam at the Cern SpS. The performances of the level-1 local trigger were tested at different energies and inclination angles of the incident muon beam. [...]
