Abstract : Traveling Wave Tubes (TWT) broadband RF amplifiers, are used in the majority of the Electronic Warfare (EW) systems. Low power TWTs are used as driver TWTs, or pre-amplifiers, and relatively high power or output TWTs are used as transmitters. TWTs are high value items; and they are usually the single most expensive item in Electronic Warfare systems. Significant quantities of TWTs are in storage at the Warner Robins Air Logistics Center (WR-ALC). Because of the time these tubes have been held in stores, there are concerns about the operational status of these depot assets. As a result of these concerns WR-ALC initiated contract F09603-86-G- 3044 Task 0020 with the Westinghouse Regional Service Center (RSC) in Warner Robins to perform an impartial engineering screening program on serviceable AN/ALQ-131 TrArTs. As the manufacturer of the AN/ALQ-131 Block l and Block II EW systems, Westinghouse had both the TWT and system background needed to develop the test criteria and perform the screening. The goals of this program was to ensure that the TWTs operated properly when issued to a field shop and to create a quantitative data base which could be used to predict the serviceability of the AN/ALQ-131 mvTs remaining in depot stores. In addition, the test data base would provide some insight into the probable serviceability of other depot TWT assets. To provide a comprehensive screening program system testing, using the AN/ALQ-131 pod and its support equipment, and laboratory testing, using TWT factory test equipment, were performed. (KAR) P. 10
