  3. Event dump GAS Close Loop?? GAS Simple System X-DAQ Patch Panels Prelim. Trigger DCS On-flight Cabling LV SY1527 System Prelim. Chamber DCS T,Thrs Sorter RPC LBB HV SY1527 System TBC HzMeter Conf DB DCC noise X-DAQ SECTOR COMMISSIONING

  4. Status of RPC Commissioning • W+2 Completed(except horiz. Sectors) • W+1 Completed(except horiz. Sectors) • W0 Sector 4 and 5 to completion Sector Test are done before final cabling RPC BARREL

  5. Status of RPC Commissioning • RE+3 pre-commissioned • RE+2 pre-commissioned • RE+1 pre-commissioned • RE-1/2 pre-commissioned Missing Front-End functional and read-out test and cooling test. Few gas leakages to be fix and understood Commissioning needs a clear resource allocation and commitments RPC ENDCAP

  7. Tower Test new On going Tower Test on Near Side Half Wheel +1 Step 1) Cabling:connectivity,CCU chain Step 2) LV up:grounding and functionalities Step 3) HV up:stability Step 4) Data Acquisition:performance, full chain Use of the MTCC set-up in Green and Balcony Barracks

  8. MTCC

  9. 10 Ottobre Entries 30712 Mean 0.3705 RMS 5.125 OF 0 B=3.8T Th=220mV 19 Ottobre Entries 30712 Mean 16.37 RMS 88.58 OF 769 B=3.8T Th=205mV B=0T Th=220mV 29 Ottobre Entries 30712 Mean 0.514 RMS 11.1 OF 119 MTCC preliminary results Noise stable during entire period NOISE

  10. HV = 8.5 kV HV = 9.0 kV HV = 9.2 kV HV = 9.4 kV HV = 9.6 kV MTCC preliminary results DT Segment extrapolation to RPC EFFICIENCY

  11. Studied RPC 3  MTCC preliminary results Start using stand-alone RPC reconstruction RESIDUALS

  12. Use of RPC MTCC results Dedicated Cosmics MC production Comparison Data Vs MC Improve the model of the simulation RPC Trigger and Reconstruction performance with realistic simulation

  14. DQM 3 Modules developed Digiused tested on FF Efficiency Barrel done Sync Specific Trigger Studies

  15. DCS HV/LV Data stored on and retrieved from OnlineDB Important for off-line RPC performance analyses HV components sensitive to temperature to be understood

  16. GAS SYSTEM • Prototype Closed Loop under test at ISR Many results to report, and to understand • New-Binos stability feature “cured” • On going Commissioning of Distributors • Gas Gain Monitor to be set-up

  17. Conclusion • Clear set of performance benchmark • Sector Test on Barrel going smoothly • Tower Test ala MTCC in preparation now • Time to devote more effort on SW • Few items to follow up closely
