Marcello Maggi 7/12/ 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

Marcello Maggi 7/12/ 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

Marcello Maggi 7/12/ B=3.8T Th=220mV B=3.8T Th=205mV B=0T Th=220mV MTCC preliminary results 10 Ottobre Entries Mean RMS OF 0 19 Ottobre Entries Mean RMS OF Ottobre Entries Mean RMS 11.1 OF 119 NOISE Noise stable during entire period

Marcello Maggi 7/12/ MTCC preliminary results EFFICIENCY HV = 8.5 kV HV = 9.0 kV HV = 9.2 kV HV = 9.4 kV HV = 9.6 kV DT Segment extrapolation to RPC

Marcello Maggi 7/12/ MTCC preliminary results Start using stand-alone RPC reconstruction Studied RPC 3  RESIDUALS

Marcello Maggi 7/12/ 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

Marcello Maggi 7/12/ DQM 3 Modules developed Digi used tested on FF Efficiency Barrel done Sync Specific Trigger Studies

Marcello Maggi 7/12/ 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

Marcello Maggi 7/12/ 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

Marcello Maggi 7/12/ 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
