Efforts were continued on the development of low-noise, traveling-wave tubes for operation in the X-, C-, S-, and L-band regions. The tubes will be environmentalized to operate under the following conditions Shock, 15g temperature, -54C to 71C altitude, 70,000 feet and vibration 5 to 55 cps. An improvement in magnet stack construction tec has given almost 100 stack-to-stack reproducibility. The first preliminary performance tests were made on the M5058 and the M5056 with the new helix design. The preliminary results for both tube types are encouraging. Author
