qPrepare for Phase II, i.e. Run 4

q ATLAS Phase II LoI: Level-1 base line proposal

  • Two-stage synchronous First Level Trigger
  • Level-0 accept rate and latency of 500 kHz & ~3 µs respectively
  • Level-1 accept rate and latency of 200 kHz & ~17 µs respectively
  • Event size at µ 200 ~5 Mbyte

q Level-0 is the Level-1 Trigger used in Run 2–3

  • Calorimeter trigger: Digital Electron & Jet Feature extractor
  • Including associated changes to calorimeter electronics
  • Excluding today’s Level-1 calorimeter trigger system
  • Muon trigger: today’s L1Muon and use of New Small Wheel track segment
  • Exception: new Level-0 CTP

q Level-1

  • RoI based Track Finding seeded by Level-0 calorimeter and muon RoIs
  • Central trigger processor (including selection based on event topology)
  • Subject to further study, increased granularity calorimeter data (seeded by Level-0)
  • Subject to further study, use of MDT’s in the End-cap (and Barrel?)

DAQ @ LHC: ATLAS Upgrade overview

qSummary

q From 2014–2022

  • 100 kHz * 2.4 Mbyte from detector into read-out buffers
  • HLT selection requires up to 50% through network
  • —> 1 Tbit/s
  • At least 1 kHz x 2.4 Mbyte to storage

q From 2022

  • Detector Readout: at least 200 kHz * 5 Mbyte into read-out buffers
  • New detector readout architecture ... blank paper
  • Assume HLT selection still only requires up to 50% through network
  • –> 5 Tbit/s

q TDAQ stresses that 200 kHz is a minimal requirement

  • After all, full readout @ 200 kHz ... still only 10 Tbit/s
  • ... 200 kHz –> 500 kHz –> 1 MHz?

q Challenge is reading out detector at higher (Level-1) rates

  • (Potentially) legacy on-detector electronics
  • Front-end link bandwidth, i.e. LoI based on today’s GBT
