Charge Collector Design

The charge collector for the Qweak chambers will use concentric strips aligned with the electron scattering polar angle ([math]\theta[/math]) and radial strips. The radial strip are not aligned with phi due to the expected phi symmetry. Six, 130 pin output connectors will be used. Two of the pins are ground and 128 carry signals from individual strips.
