3. CSC Trigger Major Milestone: Structured Beam Tests
ME 1/1
ME 1/2
ME 2/2
ME 3/2
RE1/2
Peripheral Crate #1
ME1/1+ME1/2
Peripheral Crate #2
ME2/2+ME3/2
RPC Link board Crate
Each has 2 TMB, 1 MPC
Track-Finder Crate (next slide)
First time used full Track-Finding logic to identify tracks in data
Full DAQ logging of inputs and outputs for offline comparisons
L1A generation a major synchronization accomplishment for trigger
Provided trigger for other subsystems
Marks beginning of CSC Trigger operations at CERN

4. Track-Finder Crate at CERN -- Florida, Rice, UCLA
System of multiple peripheral crates (multiple Muon Port Cards) to TF crate
Synchronization studies
Multiple Sector processors to one Muon Sorter
Fully functional in Beam Tests
Provides trigger for the experiment
Operating now for Integration tests

6. Trigger Completion
Operate fully functional trigger electronics at CERN
Employed in myriad tests & preparation activities
Tests in Electronics Integration Center
Prevessin 904 (see next slide)
Labs & row of racks for all electronics subsystems
Test interfaces & integration as much as possible before move to USC55 or slice tests
Surface & “Magnet” tests in SX5
With both HCAL and EMU
More during magnet test
Verify trigger functions & interfaces w/detectors on surface.
Installation in Underground Counting Room (USC55)
Expect start in December --”ready for crates”
Racks & Infrastructure installed
Underground Counting Room

7. Trigger Install/Commission: Path to USC55 thru Prevessin 904
Assemble one each of critical racks in central trigger core in underground counting room
Electronics Labs
trigger & electronics integration racks
Contingency in case of further delays in USC 55 occupancy
Starts Now
