    Abstract: An electron discharge tube comprises a photocathode, a dynode, a mesh having openings of non-uniform sizes on the dynode, and an anode, all in an evacuated tube. The mesh comprises a plurality of spaced first elongated elements of electrically conducting material and a plurality of spaced second elongated elements of electrically conducting material, intersecting to form openings of non-uniform sizes.
