Triggering on muon showers / Prado, J (ICTEA, Oviedo) ; Vico, C (ICTEA, Oviedo) ; Folgueras, S (ICTEA, Oviedo) /CMS Collaboration
In view of the HL-LHC, the Phase-2 CMS upgrade will replace the entire trigger and data acquisition system. The readout electronics will be upgraded to allow a maximum L1 accept rate of 750 kHz and a latency of 12.5 μs. [...]

Firmware implementation of Phase-2 Overlap Muon Track Finder algorithm for CMS Level-1 trigger / Fokow, Piotr Andrzej (Warsaw U. of Tech.) ; Leguina, Pelayo (Oviedo U.) /CMS Collaboration
The Overlap Muon Track Finder (OMTF) is one of the subsystems of the Compact Muon Solenoid (CMS) Level-1 Trigger. For the High-Luminosity Large Hadron Collider era (CMS phase-2 upgrade), a new version of the OMTF is currently under development. [...]

Upgrade of the CMS Drift Tube electronics for the High Luminosity LHC / Redondo, I (Madrid, CIEMAT) /CMS Collaboration
The electronics of the CMS Drift Tubes (DT) chambers will be replaced to operate during High Luminosity (HL-LHC). In the upgraded architecture, optical links (lpGBT, VTRX+) send all signals to the backend, where complex logic running on FPGAs will process the data within trigger latency with precision enough to profit from the full chamber resolution, which in the present system is only possible offline. [...]

Pileup mitigation in Hadron Forward calorimeter at the Level-1 trigger of the CMS experiment for the HL-LHC / Ghodgaonkar, Abhijeet (Tata Inst.) ; Sugunan, Aravind Thachayath (Tata Inst.) ; Govekar, Pranav Keshav (Tata Inst.) ; Patil, Mandakini Ravindra (Tata Inst.) ; Mazumdar, Kajari (Tata Inst.) /CMS Collaboration
The high luminosity operation of the LHC will deliver collisions with a luminosity about 10 times the original design value. This poses a big challenge for trigger and data acquisition due to nearly 200 overlapping collisions, called pile up, within the same bunch crossing. [...]

R&D of the cluster finding algorithm for CMS iRPC detector / CMS Muon Collaboration
The Compact Muon Solenoid (CMS) experiment will undergo phase-II upgrade to enhance the capacity of detectors in the High-Luminosity Large Hadron Collider era. An important extension involves the installation of the Improved Resistive Plate Chambers (iRPC) in the most forward part of the endcap muon system. [...]

Prototype Design of Global Common Module for ATLAS Experiment’s Phase-II Upgrade / Tang, S (Brookhaven) ; Bonini, F (Brookhaven ; CERN) ; Begel, M (Brookhaven) ; Benoit, M (Brookhaven ; Oak Ridge) ; Chen, H (Brookhaven) ; Filimonov, V (Mainz U., Inst. Phys.) ; Lucca, F (Buenos Aires, CONICET) ; Matakias, D (Brookhaven) ; Qian, W (Rutherford) ; Sankey, D (Rutherford) et al.
A new Global Trigger subsystem will be installed in the Level-0 Trigger as part of the High-Luminosity Large Hadron Collider (HL-LHC) upgrade of ATLAS during the upcoming Long-Shutdown 3. It will feature new and improved trigger hardware and algorithms, and an increased maximum output rate of 1 MHz. [...]

Data Preparation And Optimization For Real Time Track Reconstruction On The ATLAS HTT PRM Board / Axiotis, Konstantinos (Geneva U. ; CERN) /ATLAS TDAQ Collaboration
Custom hardware boards for pattern recognition have been developed for the fast reconstruction of charged particle tracks at the ATLAS experiment for the High-Luminosity LHC upgrade. The Pattern Recognition Mezzanine (PRM), part of the Hardware Tracking for the Trigger system, is one of the boards where track fitting and track reconstruction is being performed using linearized algorithms in an Intel Stratix 10MX FPGA.

New readout electronics for ATLAS ZDC detector / Korcyl, K (Cracow, INP) /ATLAS ZDC Collaboration
The ATLAS ZDC detectors located in the LHC tunnel detect far-forward neutrons emerging from interactions during proton-proton or lead-lead collisions. PMT signals are transferred over the 200 m long fast air-core cable to the electronics room. [...]

Particle flow reconstruction for the CMS Phase-II Level-1 Trigger / Herwig, C (Fermilab) /CMS Collaboration
The upgrade of the CMS detector for the high-luminosity LHC will include track-finding for the first time in the Level-1 trigger, enabling Particle Flow reconstruction of every event in addition to comprehensive pileup mitigation. The Correlator trigger will reconstruct isolated leptons and photons, hadronic jets, and energy sums, assisted in many cases by machine learning to benefit from the complete particle-level event record.
