6. Trigger Commissioning Plans
Operate fully functional trigger electronics at CERN
Employed in myriad tests & preparation activities
Tests in Electronics Integration Center
Labs & row of racks for all electronics subsystems
Test interfaces & integration as much as possible before move to USC55
Cosmic Challenge in SX5
Test multiple trigger components with multiple detector components during the magnet test.
Verify trigger functions & interfaces w/detectors on surface
Installation in Underground Counting Room (USC55)
Expect start by Nov 30 ‘05 -- “ready for crates”
Racks & Infrastructure installed, cooling operational
USC55
Underground Counting Room

7. Trigger Install/Commission: Electronics Integration Center: Prevessin 904
Assemble one each of critical racks in central trigger core in underground counting room
Electronics Labs
trigger & electronics integration racks
Test/integrate trigger electronics in EIC before use in Cosmic Challenge or installation in USC55
Started April 18

8. HCAL-SLB-RCT Integration in EIC - Maryland, Lisbon, Wisconsin
Sent synchronous jet data from HCAL HTR Cards thru 6 SLB over 10m copper 4Gb/s Vitesse Links to 6 Regional Calorimeter Trigger Receiver Mezzanine cards, thru Receiver Cards, Backplane and Jet Summary Card to Jet Capture Card recording output of 256 crossings. See output jets on all channels in expected crossings.

9. CSC trigger in cosmic challenge - Florida & Rice
Set-up in SX5 as operated during 2004 beam tests
Connected 6 chambers in ME+2 & ME+3
 20° slice on YE+2 SP
CCB
CSC Track-Finder will provide a cosmic muon trigger based on a coincidence of LCTs in two or more disks
The LED lights on the SP (left) and CCB (right) is the response to a 40 Hz cosmic muon rate. On the CCB, the LED about 4 down is blinking. On the SP, the 2 bottom LEDs of the array at the top of the board blink in unison with the CCB. At the very end of the movie, an LED on the left side midway from bottom to top of the array comes on. That indicates that the internal DAQ FIFO filled.

10. 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 Operation before 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 Phases with 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 < 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 L1A rate of 10 kHz.
“Single Step” Mode
Trigger rate “low”
“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 Test Triggers
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.
