36. FPGA implementation of a histogram-based parent bunch-crossing identification for the Drift Tubes chambers of the CMS experiment

Oral

The first running implementation on FPGA of a histogram-based trigger primitive generator for the CMS Drift Tubes at the HL-LHC is presented. This project is driven by the need to generate a trigger by processing the charge collection times, acquired by means of a TDC, and asynchronously shipped to the back-end. We review the design of the bunch crossing evaluation, its implementation on FPGAs...

71. eFEX preproduction module design and test

The Electron Feature Extractor (eFEX) is one of the core subsystems for the Phase-I upgrade of the ATLAS Level-1 Calorimeter Trigger. In Run 3, the eFEX will identify isolated e/g and tau candidates with much higher discriminatory power than in Run 2. The eFEX subsystem consists of 24 eFEX modules housed in two ATCA shelves. Each eFEX module has up to 200 optical input/output links and more...

In view of the High-Luminosity LHC, the Compact Muon Solenoid (CMS) experiment is planning to replace entirely its trigger and data acquisition system. Novel design choices are being explored such as ATCA prototyping platforms and newly available interconnect technologies proving links up to 28 Gb/s. Higher-level trigger object reconstruction is performed through large scale FPGAs (such as...

19. Upgrade of the ATLAS MDT Readout and Trigger for the HL-LHC

Robert Richter (Max-Planck-Institut fur Physik (DE))

Trigger

Oral

The luminosity increase of the LHC in Phase-II calls for an in-depth redesign of the entire MDT readout chain. While the high rate of primary detector signals requires increased bandwidth at each level of the data path, the MDT readout must, in addition, supply accurate coordinate information to the trigger system, leading to more reliable identification of high-pT tracks. The pre-selection of...

40. Realization of a state machine based detection for Track Segments in the Trigger System of the Belle II Experiment

Trigger

Oral

The Belle II Experiment relies on an online level 1 trigger system to reduce the background and achieve the targeted frequency of 30 kHz. Here the basis for all trigger decisions based on data from the Central Drift Camber is the track segment finding. To improve both efficiency and maintainability we restructured the original combinatorial approach to finite state machines. The new...
