Operate fully functional trigger electronics at CERN• Employed in myriad tests & preparation activities
Tests in Electronics Integration Center• Labs & row of racks for all electronics
subsystems• Test interfaces & integration as much as
possible before move to USC55
MTCC in SX5• Test multiple trigger
components with multipledetector components duringthe magnet test.
• Verify trigger functions &interfaces w/detectors onsurface
Installation in Underground CountingRoom (USC55)
• Started Mid-July ‘06 -- “ready for crates”• Racks & Infrastructure installed, cooling operational• RCT crates, power, infrastructure fully installed
• Passed CERN Safety Review• Card installation next

HCAL HTR to RCT • Used JCC to verify data• 6 cables used - all in sync• Latency measurements w/PMT
as source of HCAL TPG
ECAL TCC to RCT • Valid link established • Channel number sent as data• 2 channels on 20 m cables
sent in sync to RCT
HCAL HTR & ECAL TCC to RCT • 28 cables to RCT from 9 TCC
& 18 HCAL HTR outputs• Common clocking: LTC, TTCci• 28 channels in sync - links stable for >10 hours error free running• “Hydra” link cable checked as an option for two SLB’s to one RCT RMC
ECAL - HCAL Pattern tests• RCT can “lookup” incoming data
• LUTs can be programmed to duplicate incoming data• Have ORCA emulation to help predict outputs

RCT to Local Timing Controller (for MTCC) Tests • Receive 56 HCAL links (448 towers) in Green Barracks• Send trigger out with RCT Jet Capture Card
• OR of towers in each half using Quality Bit• Validated connection with LTC/GT
• GT ANDs top & bottom - reduces rate
RCT Jet Capture Card to GT Tests • Backup Global Calorimeter Trigger• JCC in spare VME slot of RCT Crate• Currently sends up to 4 trigger bits
• Threshold ET, e/ candidate, MIP• Tests using RCT pattern successful!
• ECAL TCC patterns yield JCC output• Synchronized to Bunch crossing 0
RCT- GCT Source Card• First test with new GCT• Completed successfully in July

A vital part of the trigger program:•EIC (Bat. 904) is the only opportunity to test a large number of channels with close to final infrastructure before moving into USC55.
•Tests done in EIC are mostly a continuation of previous integration tests done in institute labs, but performed in an environment as close to USC55 as possible: rehearsal for USC55 activities
Method:•Download and synchronously propagate test patterns within and between trigger systems
•Use simulated data & data from test beams
Goals:•Test interfaces, software, synchronization, DCS…•Prepare electronics for use in Cosmic Challenge•Gain back some time lost in the delay of USC55 by testing everything possible before installation
•Completion of Electrical Clearance tests
