Non-Destructive Evaluation of Microwave Tubes

The Navy has developed a low-cost, non-intrusive system for monitoring microwave transmitters (MTWs), and correctly identifying component failures. Current technology for monitoring MTWs is limited in that it cannot identify specific component failures within the MTW. When a MTW goes down due to a component failure, the entire MTW is often times replaced. SSC San Diego’s non-destructuive acoustic sensors can detect anomalous RF pulses, providing advanced warnings of component failure before the MTW fails. By placing these non-destructive acoustic emission sensors into new or existing MTWs, real time monitoring can take place, avoiding the wasteful failure and replacement of MTWs due to poor monitoring and specific component failure. Summary of Benefits Avoid incorrect replacement of high-value klystons, magnetrons, or MTWs In-situ prognostic capabilities provide advanced warning of a system malfunction Increase in system readiness and reliability Decrease in inventory of replacements and test systems Improved quality = "Lean Sigma Practices" Decrease in needed experience level of technicians and cost of training
