Abstract

Because the high frequency Carrier Electron Tubes were exhibiting several characteristics that were detrimental to tube manufacture such as low test yields, below nominal test parameters and difficulty of activating and aging, it was proposed to evaluate the use of a modified triple carbonate cathode coating with a reduced percentage of calcium carbonate in place of the double carbonate cathode coating that contains no calcium carbonate as the emission material.
