24. CSC Muon Trigger September 21, 2004 CMS Annual Review 24 Current Status of CSC Trigger Elements – Quick Summary n CSC on-chamber: DONE. n Endcap peripheral crate: in or nearing production u TMB Trigger Motherboard – in production, 32 out of 468 built u MPC Muon Port Card – ready for production u CCB Clock & Control Board – ready for production n Track Finder crate in counting house: nearing production u SRSP Sector Processor/Receiver – nearly ready for production u CSC Muon Sorter – prototype=final board? u Backplane – nearly ready for production

25. CSC Muon Trigger September 21, 2004 CMS Annual Review 25 CSC Triggering on Day 0 n Synchronization: u Unclear whether cosmic muons will be useful underground. u Anode and cathode clocks synchronized for communications by programmed front-end pulse injection and other techniques such as CRC checks. u Fine (2ns step) delay of anode data needs colliding beams and LHC clock. l A few seconds of collisions should suffice, analysis time=total time. Need several settings per ALCT since TOF etc vary. u Global CSC data alignment accomplished by comparing data to LHC BX gaps. May take several hours. Local or global DAQ okay. n Chamber alignment and Track Finder coincidences: u Start with “open trigger”, safe mode, and run Track Finding algorithm & check u Open trigger = 1-3 stations per 60 o sector in coincidence n Cross-checks: u Chamber level: DAQ versus Trigger paths u Chamber level: RPC versus CSC paths. u Physics level: e.g. high P T jet triggers yield some punchthrough, decay muons

26. CSC Muon Trigger September 21, 2004 CMS Annual Review 26 Conclusions n The CSC electronics are in very good shape: u Test beam showed that the entire chain of CSC trigger electronics work very well together under “battle conditions” u Production starts soon for Track Finder (MPC, SP) boards u Final prototypes are being tweaked for minor issues. n Plenty of work ahead on the software side for calibration, synchronization etc.
