In an invention detector having an array of detectors, grounding pads are positioned in the spaces between some detectors (data detectors) and other detectors (reference detectors). The grounding pads are kept at zero electric potential, i.e., grounded. The grounding serves to (1) drain away electrons and thereby prevent an unwanted accumulation of charge in the spaces, and (2) cause the electric field lines to be more perpendicular to the detectors in regions near the grounding pads. |
