40 MHz Level-1 Trigger Scouting for CMS / CMS Collaboration
The CMS experiment will be upgraded for operation at the High-Luminosity LHC to maintain and extend its physics performance under extreme pileup conditions. Upgrades will include an entirely new tracking system, supplemented by a track finder processor providing tracks at Level-1, as well as a high-granularity calorimeter in the endcap region. [...]

40MHz Scouting Muon Studies /CMS Collaboration
The 40MHz Scouting system is a novel data acquisition system, parallel to the Level-1 trigger, that collects the Level-1 trigger primitives at the full bunch crossing rate. It was first demonstrated in 2018 at the end of Run 2 and the system has been updated for Run 3. The Run 3 demonstrator captures data from multiple sources: the outputs of the Global Muon Trigger (GMT), data from Calorimeter Layer 2 and the Global Trigger (GT) and the inputs of the Barrel Muon Track Finder (BMTF)..

First Data Taken with the Level-1 Data Scouting System /CMS Collaboration
The Level-1 40 MHz data scouting system will record trigger objects created by the Phase-2 Level-1 trigger at the bunch crossing rate, enabling novel analyses and improving monitoring capabilities. At the end of 2018 and from the beginning of LHC Run-3 a demonstrator system has been in operation, taking data initially from the CMS Phase-1 Global Muon Trigger and recently, from mid-2021, also from the CMS Phase-1 Calorimeter Trigger. First data obtained this novel system are shown here. [...]

The Phase-2 Upgrade of the CMS Detector / Pásztor, Gabriella (Eotvos U.) /CMS Collaboration
The high-luminosity upgrade of the Large Hadron Collider (HL-LHC) will provide a unique opportunity to extend the physics reach of the CMS experiment by achieving unprecedented precision in the study of Standard Model (SM) processes and by increasing its discovery potential for physics beyond the SM to higher energy scales and rarer processes. The HL-LHC, however, will also bring experimental and instrumental challenges with its harsh environment: high radiation levels, high number of particle collisions per bunch crossing (pileup of 140-200), and extreme final state particle multiplicities [...]

40 MHz Scouting for the CMS Level-1 Trigger / Giorgetti, Sabrina (INFN, Padua) /CMS Collaboration
The Level-1 trigger Data Scouting (L1DS) is a novel data acquisition system under development for the Phase-2 CMS detector at the High-Luminosity LHC (HL-LHC). Its purpose is to capture and process Level-1 trigger (L1T) information at the bunch crossing collision frequency of the LHC preceding the standard L1T selections. [...]

Triggering on electrons, photons, tau leptons, jets and energy sums with the CMS Level-1 trigger / Bhowmik, Sandeep (NICPB, Tallinn) /CMS Collaboration
The Compact Muon Solenoid (CMS) experiment implements a sophisticated two-level triggering system composed of the Level-1, instrumented by custom-design hardware boards, and a software High Level Trigger. A new Level-1 trigger architecture with improved performance is now being used to maintain high physics efficiency for the more challenging conditions experienced during Run II. [...]

Performance of CMS Level-1 Trigger Data Scouting during LHC Run 3 / Giorgetti, Sabrina (INFN, Padua) /CMS Collaboration
The CMS Level-1 Trigger Data Scouting (L1DS) system represents an innovative approach within the CMS experiment, enabling the acquisition and processing of Level-1 Trigger (L1T) objects at the full LHC bunch-crossing (BX) rate of 40 MHz. The system will be fully deployed as part of the CMS Phase-2 Upgrade at the High-Luminosity LHC (HL-LHC), harnessing the improved Phase-2 L1T design, featuring tracker and high-granularity calorimeter data for the first time.
