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

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 SP1 MS (x1) SP2(x 12) x 1 L1A signal distributed out of crate from CCB

CSC Trigger Muon Port Card & Sector Processor Muon Port Card (Rice): 6 built w/FPGA mezzanines, fully tested in beam, in radiation, in crate w/ 7 Trigger Motherboards connected to Sector Processor Final board (w/small changes) is under final testing followed by production start. Sector Processor (Florida): PPP built & tested in structured beam In production (1st 2 made) Total needed: 12 15 X 1.6 Gb/s optical links from MPC Mezzanine card TLK2501 serializers Optomodules GTLP Receivers VME Interface (glue logic) Xilinx Virtex-2 800 User I/O

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

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
