Set-up in SX5 as operated during 2004 beam tests• Connected 6 chambers in ME+2 & ME+3
20° slice on YE+2 SP
CSC Track-Finder will provide a cosmic muon trigger based on a coincidence of LCTs in two or more disks

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)

Preparing for OperationPreparing for Operationbefore beam & after install/commissionbefore beam & after install/commissionPreparing for OperationPreparing for Operation
before beam & after install/commissionbefore beam & after install/commissionRun 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.

Trigger Commissioning PhasesTrigger Commissioning Phaseswith first collisionswith first collisions
Trigger Commissioning PhasesTrigger Commissioning Phaseswith first collisionswith 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.

Trigger Hardware:• Finished with, in or about to start production
Trigger Integration• Much testing already done• Program of Electronics Integration Center Tests• Trigger Program for Cosmic Challenge
Trigger Commissioning• Realistic plan in place starting with USC55 occupancy in December• Operation with downloaded simulated data in USC55• Orderly connection and checkout with subsystems, central systems• Operations & testing w/o beam (downloaded & cosmic) planned until
startup• Use of single beams for halo muon triggers & beam-gas events
Plan developed for first data run operations• 5 Phases:
• synchronization & testing, technical validation of data transport, data content validation, data physics evaluation, physics feedback
