Abstract: In a reticulated grid cathode which has a flexible connection at one end to the conductor for the filament current present inside the cathode, the flexible connection consists of a number of thin metal strips of the same thickness. The strips constitute an approximately semi-circular arc and each consist of two strips of preferably the same thickness. In order to minimize the bending stress occurring in the strips, the diameter of the arc formed by the strips is chosen to be as large as possible relative to the radial dimensions of the cathode.
