CONTROLLER

Crate Controller• Interface to DCS • Provide Slow Control services Download FPGA, thresholds, calibration constants; LV monitoring, debug electronics.

DAQ Motherboard (DMB)• Initiates FE digitization and readout • Receives and sends FE data to DDU• Provides Slow Control interface to FE boards (VME-JTAG)

TRIG Motherboard (TMB)

Muon Port Card (MPC)

Clock Control Board (CCB)• Interfaces to the TTC system • Distributes LHC clock, resets, L1- Accept

Trigger Motherboard Receives CFEB comparator hits, ALCT stubs, RPC hits. Generates Cathode LCT, matches ALCT with CLCT, outputs LC

Ts to backplane, stores data for readout.

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

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

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

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.

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..

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.

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

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
