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.

Commissioning TriDAS ModesCommissioning TriDAS ModesCommissioning TriDAS ModesCommissioning TriDAS Modes

Normal Mode•Trigger rate at 50 kHz (evolves from 12.5 50 75 100 kHz)

“Safe” Mode•Trigger rate < 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% @ 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.
