Extended-Interaction Klystron for the AN/TPS-43-E Radar System
Abstract
This effort was directed at developing and demonstrating a form, fit and functional extended-interaction klystron replacement for the VA-145E twystron in the AN/TPs-43E radar system. A suitable extended-interaction output circuit had already been demonstrated under Contract F30602-78-C-0029. A total of three tubes were built and tested under this program. All performed to full specifications when tested under normal factory test conditions. However, none of the three tubes performed satisfactorily in a simulated AN/TPS-43-E system (a Westinghouse TPS-3 system). Unstable tube operation was caused by the rotary joint, which has a severe mismatch near the operating frequency band. After this condition was discovered with tube S/N 001, tubes S/N 002 and S/N 003 were built in an attempt to overcome this near-short-circuit condition by reducing the output resonator impedence near the problem frequencies. This solution was only partially successful. These later tubes operated satisfactorily at some orientations of the rotary joint but would become unstable at the worst mismatch points. The task of designing a special tube that would include novel features for overcoming the severe system mismatch problem was determined to be outside the scope of this contract and this effort was concluded.
