LONG-LIFE COLD CATHODE STUDIES FOR CROSSED-FIELD TUBES

Abstract

The objective of the present cold cathode study program is to achieve long life cold cathode performance for crossed-field amplifiers. In this study, selected cold cathode materials will be evaluated as to: their secondary emission properties, their ability to withstand environmental factors expected in a crossed-field amplifier, and their crossed-field amplifier performance. Based on the above experimental information and pertinent theoretical calculations, a life prediction chart will be established for a number of cold cathode materials. The program is divided into two concurrent phases, phase A being concerned with the measurement of various pertinent properties of cold cathode materials outside of the tube environment, and phase B involving the evaluation and life testing of selected cathodes in a crossed-field amplifier.
