Overview of Traveling Wave’s Tubes Reliability Models
P. 169-174.
Traveling wave tubes are actively used in various radio transmitting devices. However, the analysis of modern literature sources showed that there are no mathematical models that allow to take into account the influence of technical parameters of traveling wave tubes on the failure rate, and, as a consequence, on the time to failure and resource.
