Figure 4 Scan results from D03F2 Z sdie interwafer boundry region.

Fault data for the selected detector strips shown in figure 4 are listed in the bad channel list for this detector. In comparing the fault data to the strip output levels the open (plucked) channels are evident (ie. 32,37 & 78) as are the channels which are shorted to floating strip neighbors (ie. 18,23 &34).

Figure 5 Circuit Analysis for Neighbor Strip Charge Collection in a normal region.

Based on the optical spot size the middle strip will receive one unit of charge (ie. q1=1.0) with the near neighbors receiving 90% and the next neighbors receiving 75%. of the light. When the
