10. Maciek Kudla, RPC Review – Link System 13.06.2006 LBB - Frontplane Control Bus between LBs and CB

11. Maciek Kudla, RPC Review – Link System 13.06.2006 Control/Readout Crate - CCS Board 3 CCS FEC Boards drives 18 CCU rings

12. Maciek Kudla, RPC Review – Link System 13.06.2006 MTCC – Link system Detector: (installed) YE+1 - 2 LBBs, YB+2 - 2 LBBs, YB+1 - 1 LBB; Green barack: (installed) Control/Readout Crate (1 CCS, 1 DCC), Trigger Crate (1 TB), TTC Crate (TTCci, LTC, TTCex); 904: (installed, used for software development) 2 LBB, Control/Readout Crate (1 CCS, 1 DCC), Trigger Crate (1 TB), TTC Crate (TTCci, LTC, TTCex);

13. Maciek Kudla, RPC Review – Link System 13.06.2006 Link system - Status and schedule LBB - 36 installed on detector, 17 ready for installation, 43 - to be assembled, LB - 55 used MTCC, 6 used 904, 400 to be delivered July, CB - 8 used MTCC, 3 used 904, 60 to be delivered July, FP - 8 used MTCC, 3 used 904, 60 to be delivered July, Control Crate - 1 for MTTC, one for software development in 904

14. Maciek Kudla, RPC Review – Link System 13.06.2006 ProductionTests of LBB components Step 1 - Factory - basic tests (to assure the production quality and speed-up repair work): 1.LB tested with the production Lappeenranta tester 1.all outside connections are covered, 2.all connections between Xilinxes, 3.QPLL locking; 2.CB tested with BSCAN 1.some of the outside connector, 2.all connection between chips with BSCAN support, 3.possibly the flash programming (?); Step 2 – Lappeenranta - "system, functional test" full crate assemblied (2xCB, 18LB, 2FB): 1.test boards used instead of FEBs, 2.this should cover the things that are not included in Step 1 1.CB outside connections, 2.flash programming; Step 3 – 904 - Commissioning: 1.LBs, CBs in full ring setup – Step 2.1 repeated ~1 hour needed

15. Maciek Kudla, RPC Review – Link System 13.06.2006 RPC Link system Integration Status All tasks: Control of FEBs (thresholds etc), Synchronisation FEB data to LHC clock, Transmission FEB data (in compressed form) to Trigger Boards via optical links Diagnostic readout (RPC histograms, events) via CCU rings, Injection of test patterns at FEB and LB level Tested in several tests runs and in 904 Integration Area i.e synchronisation quality very good (< 1ns), Long CCU chain with redundacy tested, etc

16. Maciek Kudla, RPC Review – Link System 13.06.2006 Summary System in production stage, Software development advanced (see Bunkowski’s talk), Heavy cabling and detector installation before us...
