61. An FPGA-Based Track Finder for the L1 Trigger of the CMS Experiment at HL-LHC

Davide Cieri (STFC - Rutherford Appleton Lab. (GB))

Trigger

Oral

A new tracking detector is under development for use by the CMS experiment at the High-Luminosity LHC. This upgrade will allow to reconstruct within a few microseconds charged particle tracks with transverse momentum above 3 GeV, for use in the Level-1 trigger. A concept for an FPGA-based track finder using a fully time-multiplexed architecture is presented, reconstructing tracks using an...

23. The ATLAS Muon-to-Central Trigger Processor Interface for the Phase-I Muon Trigger Upgrade

Trigger

Oral

The Muon-to-Central Trigger Processor Interface (MUCTPI) of the ATLAS experiment at CERN will be upgraded for run 3 of the LHC. The current system, a full 9U VME crate, will be replaced by a single AdvancedTCA blade, based on state-of-the-art FPGA technology and high-density ribbon fibre-optic transmitters and receivers. The module uses a System-on-Chip (SoC) with a processor running an...

27. Development of the jet Feature EXtractor (jFEX) for the ATLAS Level 1 Calorimeter Trigger upgrade at the LHC

Marcel Weirich (Johannes Gutenberg Universitaet Mainz (DE))

Trigger

Oral

To cope with the enhanced luminosity delivered by the Large Hadron Collider in 2021, the ATLAS experiment has planned a major upgrade. The first level trigger based on calorimeter data will be upgraded to exploit fine-granularity readout using a new system of Feature Extractors (FEXs), each optimized to trigger on different physics objects. This presentation is focused on the jet FEX.
The main...

98. FELIX: the New Detector Readout System for the ATLAS Experiment

Frans Philip Schreuder (Nikhef National institute for subatomic physics (NL))

Trigger

Oral

Starting during the upcoming major LHC shutdown (2019-2021), the ATLAS experiment at CERN will move to the Front-End Link eXchange (FELIX) system as the interface between the data acquisition system and the trigger and detector front-end electronics. FELIX will function as a router between custom serial links and a commodity switch network, which will use industry standard technologies to...

109. A High Luminosity LHC Track Trigger for the CMS Detector

Prof. Brian Winer (The Ohio State University)

Trigger

Oral

During the High Luminosity LHC, to maintain a managable trigger rate and achieve its physics goals,the CMS detector will need charged particle tracking at the hardware trigger level. The tracklet approach is a track-finding algorithm based on a road-search algorithm that has been implemented on commercially available FPGA technology. This algorithm has achieved high performance in...

144. Development of a High-Throughput Tracking Processor on FPGA Boards

Riccardo Cenci (SNS and INFN-Pisa, Italy)

Trigger

Oral

We present the latest results on the prototype of a tracking processor capable of reconstructing events in a silicon-strip tracker at about 40 MHz event rate with sub-microsecond latency. The processor is based on an advanced pattern-recognition algorithm, called “artificial retina”, inspired to the vision system of the mammals. We design and implement this processor on a board equipped with...

185. Design and Performance of the Upgrade of the CMS L1 Trigger

Costas Fountas (University of Ioannina (GR))

Trigger

Oral

The upgraded CMS Level-1 trigger is designed to improve the performance at high luminosity and large number of simultaneous inelastic collisions per crossing (pile-up). During the technical stop at the beginning of 2016, all the electronic boards of the CMS Level-1 trigger have been replaced and the upgraded electronics tested, and commissioned with data. The upgrade of both the Stage-1 and...

158. A Real-Time Demonstrator for Track Reconstruction in the CMS L1 Track-Trigger System Based on Custom Associative Memories and High-Performance FPGAs

Trigger

Oral

A Real-Time demonstrator based on the ATCA Pulsar-IIB custom board and on the Pattern Recognition Mezzanine (PRM) board has been developed as a flexible platform to test and characterize low-latency algorithms for track reconstruction and L1 Trigger generation in future High Energy Physics experiments. The demonstrator has been extensively used to test and characterize the Track-Trigger...

166. The ATLAS Fast Tracker System

Tomoya Iizawa (Waseda University (JP))

Trigger

Oral

The Fast Tracker (FTK) system, one of the ATLAS trigger upgrades, is presently being commissioned. The information from the 100 million channels of the tracking detectors is presently exploited at the HLT only for a subset of the events or for limited detector regions due to timing limitations. The FTK system is designed to deliver full event track reconstruction for all tracks with pT above 1...
