A STUDY AND INVESTIGATION OF A PREDICTIVE RELIABILITY MODEL FOR HIGH POWER KLYSTRON TUBES.
Abstract
Klystron field failure data were analyzed and a predictive reliability model was developed. The mathematical model express the probability of survival (reliability) as a function of various physics-of-failure phenomena. The phenomena are emission depletion, filament failure, gas failure, output window failure (multipactoring), sublimation failure, and mechanical failure. Each is treated separately. The relative effects of each of these factors are expressed by proportionality constants, and the manner in which each influences tube reliability is expressed by a reliability function. In addition, expressions were developed to relate tube pressure and pulse emission density to average tube life. This study indicates that the reliability of high-power klystrons can be predicted.
