Presentation Transcript

  1. Engineering: MWPC design configuration schemas

  2. Wire Pad Chamber (WPC) , one gap Avalanche Cdet in parallel to current source (not shown) will reduce current flow to amplifier as ratio of impedances (full Spice-model see below)

  3. 2-gap/layer Wire Pad Chamber (WPC) OR-ing (double signal) Independent HV sources (for reliability)

  4. Cathode Pad Chamber (CPC), one gap Single Cathode Read-Out (SCRO)

  5. Cathode Pad Chamber (CPC), one gap Double Cathode Read-Out (DCRO) Double signal

  6. Combined Wire strip and Cathode Pad Chamber (WCPC) Bad design Rather large loop

  7. WCPC (Single Cathode RO scheme)

  8. WCPC (Double Cathode RO scheme) Double signal

  9. MWPC readout schemes for M1R1 CPC (SCRO) CPC (DCRO)

  10. Anode readout INFN chambers M1+M5 R4 0mm 53.8mm 39.8mm 25.8mm 11.8mm 0mm -20.7mm +21.3mm -6.7mm +7.3mm SPB

  11. Anode readout PNPI chambers M2+M3,+M4 R4 0mm 54.8mm 10.2mm 0mm -22.3mm +22.3mm SPB

  12. Anode readout CERN chambers M2+M3 R1+R2 0mm 54.2mm 38.8mm 26.2mm 10.8mm 0mm -21.7mm +21.7mm -6.3mm +6.3mm SPB The additional ground connector we have at present is not drawn.

  13. Double Cathode readout (CERN chambers) - Single Cathode readout INFN and CERN chambers have just less connectors on equivalent positions - INFN uses no male and female parts, as CERN does ±23.2mm ±18.8mm ±9.2mm ±4.8mm 0mm OPB
