ABSTRACT:
A grid electrode for an electron tube with planar electrodes consists of a planar array of fine wires mounted on a support frame. The support frame has a circular outside rim and interconnected interior elements dividing the area inside the rim into three or more separated apertures. The interior elements include radial elements connected to non-radial elements, forming a mechanically rigid structure with good heat conduction to the outside rim which resists buckling out of its plane when differentially heated.
