Eight 715B tubes were tested by recording oscillograms of the various electrode currents under arcing conditions and simultaneously making visual observations of the locations of the arcs. The results are given and some conclusions are drawn. Measurements on the thermionic emission of 18-8 stainless steel when contaminated by the material evaporated from an oxide cathode have been concluded. The results show that zirconium-clad molybdenum, gold-plated molybdenum, and carbonized nickel are all superior to this material as regards use as a grid material. Author
