High Current Density Cathodes
Abstract
This is the last of a series of reports describing an experimental study of the critical factors and mechanisms involved in achieving high- emission-density cathodes capable of long life and reliable operation in electron tubes. Detailed results of the work of the last reporting period of this investigation are included herein, along with a review of the more significant developments of the entire two-year program. All of the objectives of the program have essentially been met, and in some cases exceeded, resulting in a tungstate cathode which represents an advance in the state of the art for high current density emitters. Reliability and reproducibility were demonstrated by consecutively fabricating and life testing eighteen cathodes. No rejects or deviations were encountered, and initial characteristics were uniform for the entire group.
