DESCRIPTION
“0V” Referencing Paths 1.The Strip Bias line on the detector 2.The HV bias return line on the bus tape (if connected) 3.The Shield Of these three paths, the shield has the lowest impedance (certainly resistance). It’s not really a shield, it’s the dominant return path! If we provide an alternate low impedance path, we may be able to connect the shield at one point only. Module performance may improve. Try a wire between the PPB board connectors First test – very slight improvement? Inconclusive…
