Abstract: A grid for an electron tube comprises an axially extending helically wound continuous flat metallic strip or ribbon. The smallest dimension of the grid is along the length of the tube and is positioned in the lateral path of electrons between an inner central cathode and an outer concentric anode to minimize electron interception and excessive heating of the grid. The thin edges of the ribbon are secured in peripheral slots along a plurality of longitudinal support rods disposed around a circular area. The larger flat surfaces of the ribbon, extending in a transverse direction from the support rods, provide improved structural rigidity and heat dissipation.
