Grothe Full Board Production & Test (2004-2005): ~ 150 each Receiver & Electron Cards, ~ 20 each Jet, Clock Cards, Backplanes & Crates need testing - All Repair & Inventory - R. Fobes Test full crates for delivery (2005) 1 year for testing full complement of crates - all Use custom card to capture output of J/S - Jet Capture Card - Under design - T. Gorski Provides trigger for slice test

17. S. Dasu, University of Wisconsin September 2003 - 17 Integration and Chain Tests Integration Tests (2003) Serial Test Cards for input link tests 1 pair at CERN for ECAL integration since March. 1 pair at Princeton for HCAL integration since June. Remaining 6 are being used for receiver mezzanine card production testing at UW Will be reused to pump data to RCT for full test (2005) Pre-production Prototype Full Crate tests Global Calorimeter Trigger (Bristol group) integration at Madison in August is successful - Termination scheme agreed - Minor changes to UW JSC and Bristol IC Integration Tests (2004) Augment above tests with additional electronics from ECAL, HCAL, & GCT groups as becomes available. Initiate Slice Test

18. S. Dasu, University of Wisconsin September 2003 - 18 Slice Tests and Trigger Commissioning Slice Tests (Starting Late Summer 2004) Use full crate of tested production boards Will remain at CERN as spare boards and crate JSC Output Capture Card provides test trigger Personnel: M. Grothe moves to CERN, assisted with visits by others Trigger Commissioning (Starting April, 2005) All eighteen crates - fully tested and shipped to CERN All electronics rechecked in electronics test facility Full commissioning underground in USC55 Personnel: When production finishes, P. Chumney moves to CERN to join M. Grothe, assisted with visits by others.

19. S. Dasu, University of Wisconsin September 2003 - 19 RCT Conclusions Regional Calorimeter Trigger All pre-production prototype boards and ASICs built & validated All boards, ASICS, & crates are either produced, in production or about to start production Integration tests w/ECAL,HCAL, GCT have started Very good progress, but… Major work from now on: Production Testing of ~1800 Boards Software Development - Integration with XDAQ Slice Test Preparation + Software Installation and Commissioning Operations! We have the team in place to do the job!
