USC55 Trigger Schedule Overview

• Four phases of activity in USC55
• Installation, Detector Integration, Central
  Integration, Commission

11
Trigger Install Schedule - I

• Install/Commission Trig. Crates Dec 05 - Apr
  06
• Tested Trigger Crates installed, re-tested,
  interconnected, inter-synchronized
• Regional and Global Detector trigger systems
  integrated with each other and Global Trigger
• Integrate w/Detector Elect. May 06 - Oct 06
• Cal Trig connected to E/HCAL USC55 electronics
• Muon Triggers connected to optical fibers
  carrying trigger data from detector
• Global Trigger connected to TTC distribution
  system
• Operation with Local DAQ

12
Trigger Install Schedule - II

• Integrate w/Central Trig. DAQ Nov 06 - Apr 07
• Subset of triggers available to detectors in
  UXC55
• Dedicated testing with individual detectors
• Detailed synchronization testing of all systems
• Testing with Central DAQ
• System Commissioning May 07 - Jun 07
• Full capability of trigger system available
• Tests with all detectors and trigger operating
  simultaneously together and partitioned
• Trigger and DAQ can operate in 8 separate
  partitions
• Ready for single beam commissioning, Jul 07
• Beam-gas synchronized triggers
• Halo muon events (see following slides)

13
Preparing for Operationbefore beam after
install/commission

• Run as much of CMS as possible integrated with
  TriDAS for as long as possible to shake out
  problems.
• Run for long periods of time with artificially
  generated data of as high a volume a possible
  loaded as close to the front ends as we can
  manage with as high a trigger rate as we can
  handle.
• This type of continuous "stress-testing" should
  help us to make the system robust.
• Also run for long periods of time with cosmic
  triggers
• Download simulated data in both the readout and
  trigger streams
• See if we can pass these all the way to yield
  triggers and physics signals on tape.

14
Trigger Commissioning Phaseswith first collisions

• 1. Synchronization Trigger testing/evaluation
• Determine that data is being properly set up
  (e.g. synchronized), triggered and transported to
  farm nodes.
• 2. Technical validation of subdetector data
• Determine from detector data written to farm
  nodes that detectors are indeed being read out
  properly and if the data is indeed correct
  technically
• 3. Evaluation/calibration/validation of
  subdetector data
• Study the subdetector data calibration and
  performance to validate its content for physics
  analysis
• 4. Evaluation of data by physics groups.
• Make basic physics plots of detector data to
  validate performance
• 5. Feedback from Physics Groups.
• Transport of min-bias data to the remote Tier-1
  centers for input into the simulation and
  regeneration of our simulation samples
• Calculation of trigger efficiencies and feedback
  to the trigger group on physics problems with the
  day 1 trigger set.

15
Commissioning TriDAS Modes

• Normal Mode
• Trigger rate at 50 kHz (evolves from 12.5 ? 50 ?
  75 ? 100 kHz)
• Safe Mode
• Trigger rate lt 10 kHz
• Level-1 Latency 3.2 ?s (128 bunch crossings - bx)
• Un-buffered Trigger Rule
• Each L1A separated by at least 8.75 ?s
• Assures that all detectors are read out before
  next L1A - no storage of additional events after
  each L1A.
• Limit set by tracker presh., deadtime of 9 _at_
  L1A rate of 10 kHz.
• Single Step Mode
• Trigger rate low
• Level-1 Latency 3.2 ?s (128 bunch crossings - bx)
• Handshake Trigger Rule
• After each L1A, Global Trigger System raises busy
  and waits for DAQ, to lower the busy after the
  event has been successfully read out.
• Large deadtime, only usable for debugging and
  initial commissioning.

16
Initial Trigger Menu

• Level-1 Trigger Totally Open
• Calorimeter low ET or any muon (no PT cut)
• Other candidate triggers for later running are
  active for diagnostic and study purposes
• Continue Halo Muon Cosmic triggers
• Test Triggers
• Dedicated runs and possible operation during
  abort gaps to verify detector functionality and
  synchronization.
