Engineering: MWPC design configuration schemas
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)
2-gap/layer Wire Pad Chamber (WPC) OR-ing (double signal) Independent HV sources (for reliability)
Cathode Pad Chamber (CPC), one gap Single Cathode Read-Out (SCRO)
Cathode Pad Chamber (CPC), one gap Double Cathode Read-Out (DCRO) Double signal
Combined Wire strip and Cathode Pad Chamber (WCPC) Bad design Rather large loop
WCPC (Double Cathode RO scheme) Double signal
MWPC readout schemes for M1R1 CPC (SCRO) CPC (DCRO)
