  13. SP/MS Mezzanine Card Status • Contains Track-Finding algorithm • Same mezzanine card is used for Muon Sorter • The previous (2002) prototype was fully validated • Production version of mezzanine card fully compatible with prototype • Production is complete

  14. Track-Finder Production: Complete! 21 Sector Processors built 12 sectors, + spares, + test stands,+2 from inferior vendor 2 spares require reworking

  15. Muon Sorter • Sorts up to 36 muons from 12 SP’s and transmits best 4 to GMT • Only 1 needed in CMS Rice LVDS drivers and SCSI-3 connectors GTLP backplane interface

  16. Full TF Crate Tests • Test of complete system took place at Rice University • Final system works! • All specs met, including overall latency • Ready for data at CERN

  17. Status of PC Electronics at CERN • 60 peripheral crates on detector disks • ALCT/CFEB Installed on chambers • BP 30/60 Production finished: 1/7/06 • 15 more arrive about every 2weeks • CRB 80/60 All at CERN and Tested • MPC 68/60 All at CERN • CCB 76/60 All at CERN • TMB 350/468 Production finished: 1/7/06 • 40 more will be at CERN by end of June 2006 • 500 will be at CERN by end of July 2006 • RAT 240/468 Production finished: 1/7/06 • 60 more will be at CERN by end of June 2006 • 540 will be at CERN by end of July 2006

  18. Status of TF Electronics at CERN • One Track Find Crate in counting room • SP 5/12 21 SP’s produced • Will be sent as needed • MS 1/1 5 MS’s produced • Will be sent as needed

  19. Peripheral Crates - Assembly • Progress at ISR • Assemble PC • Crates structures are all assembled • Back Planes, BP, installed on 40 PC • 24 BP on hand to be installed • CRB, Crate Regulator Boards, attached to BP on 36 PC • All assembled and tested – 80 units • Install boards and Test Electronics • 30 PC tested and shipped to SX5 – FULL set for PLUS end • Schedule for remainder • Assemble crates as BP arrive • Install and test as boards arrive • 2-3 PC can be completed per day • Easily stay ahead of installation at SX5 • Expect to finish 60+ PC by end of July ‘06

  20. Peripheral Crates - Installation • Work Progress at SX5 • Install and prepare Racks • PLUS end racks ALL prepared and installed • MINUS end • All (12) mini-racks prepared and 2 installed, 10 in storage area • 2 x 56U racks installed in ME-1, NOT prepared • NO other 56U racks installed (4) • Have NO turbine units for these racks • NO estimate on turbine delivery to CMS • Install PC, insert boards, and attach skew clear cables • All PC installed in PLUS end • No PC installed in MINUS end • Will be starting installation soon • Making preparations to install while closed

  21. Installed PC • PC on Top of YE+1 • ME+1/3 & ME+1/4 • Mini-rack with 2 PC’s • Each with 9 CSC’s • Installed and Tested

  22. Installed Track Finder Crate at SX5 patch panel, optical links to MPCs EMU TTC Crate Muon Sorter SP: MPC inputs CCB 01 with ribbon out SP: DT connection Ribbon takes ECL L1A-req to NIM crate.

  23. 904 (CERN, Prevessin) • 904 is our CERN backup test stand & pit stop • we should have ~100% redundancy in the CSCTF system here at all times • we have 2 spare crates here • 3 SP05 • 4 DT-transition boards • a PC running the latest CSCTF online s/w • connections to a TTC crate, peripheral crate. • CCB04, MS, CAEN 2718 etc.. • the system here is running constantly and is where the CERN based software development takes place.

  24. 904 EMU LAB TTC Crate TF Crate peripheral Crate PC:: emulab03

  25. Slice of EMu at MTCC • One 60° Trigger Sector on the Positive Endcap: • Sector 5, overlap with DT sectors 10-11 • Multiple stations on multiple disks • YE+1, YE+2 (and YE+3) • ME+1, ME+2, ME+3 (and ME+4) • Total of up to 36(39) chambers YE2 YE3 YE1 ME4 ME3 ME2 ME1 DT-11 DT-10

  26. Trigger at MTCC • Self-trigger on cosmics: TF/SP • CSC standalone system running stably for over a year • Trigger criteria very configurable; • baseline is a coincidence between LCTs from any two stations • we can also trigger on single LCTs from any required chambers • eg we have been providing HCAL with triggers from single hits in the ME1’a’ overlap region • we may wish to narrow down the eta roads cuts to point more at tracker during MTCC etc etc..

  27. PC Installation for MTCC • Test PC plus chambers • Plan to finish before magnetic field running starts • ME+1 >> ALL tested • 10 of 12 tested – 2 in MTCC • ME+2&3 • 2 of 12 tested – both in MTCC • ME+4 • 2 of 6 tested • Minus Plans • Can test as access permits during MTCC • With magnetic field OFF and access to towers on minus end caps can connect / dis-connect testing computer in ~10 minutes • Expect ample time to finish while YB’s are being lowered.

  28. Status of Track Finder Crate for MTCC • All hardware necessary to fulfill our full MTCC deliverable is now installed at SX5/green barracks • Production trigger crate • SP05 (+ 1 spare) • CCB01 :allows front panel read out of ECL trigger pulse, sent on to (L/C)TC • EMU DDU to read out trig data (local spy & s-link to DAQ FRL) • commissioning of the final path CSC TF --> DAQ FRL is the current focus • nb the main CSC detector DAQ -->FRL is already commissioned! • DT-TF interface card mounted, cables ready to be connected

  30. Conclusion CSC Muon Trigger system is in very good shape: • For MTCC: • Installation/commissioning of peripheral crates will be ready • Track Finder Crate is ready for MTCC • Installation/commissioning of peripheral crates is on schedule • Track Finder Crate is running for over a year
