ABSTRACT:
A grid gates a stream of ions when a D.C. potential is applied between two sets of interdigitated wires included in the grid to produce a D.C. field. The improved grid disclosed herein contains the two sets of interdigitated wires in a single plane so that the D.C. field is precisely normal to the ion current flow direction to prevent a residual ion current flow when the grid provides the gating effect.
