Abstract:
A method for manufacturing a gating grid for a charged particle stream, the gating grid comprising a first and second set of electrically isolated, equally spaced wires that lie in the same plane, the respective sets of wires to be applied to alternate potentials, the method comprising the steps of:selecting an insulating substrate material to serve as a frame for a gating grid; patterning a set of conductive portions on opposing sides of a hole formed in the substrate; aligning a first individual section of wire from a conductive portion on one side of the hole, across the hole to a conductive portion on a second side of the hole; tensioning the individual wire section thus stretched from one side of the hole to the other side; and bonding first one side of the individual wire section to the conductive portion on one side of the hole and then next bonding the same individual wire section to the second conductive portion on the other side of the hole; and repeating the steps of aligning, tensioning, and bonding other individual sections of wire.
