    Patent number: 7529075
    Abstract: A representative system for providing an electric field comprises an electrically insulated frame, guard members and endplates. The frame incorporates a top, a bottom, opposing sides and opposing ends, with the sides extending between the top and the bottom. Each of the ends engages the top, the bottom and the sides. The frame defines an interior. The guard members are suspended within the interior of the frame, with each of the guard members being formed of metal tubing. The guard members are spaced from each other and located along a length of the frame such that the guard members are oriented substantially parallel to the ends of the frame. The endplates are positioned at the ends of the frame. The frame, guard members and endplates are operative to form an electric field within the interior of the frame responsive to an electric potential being applied to at least one of the endplates.
