DEVELOPMENT OF LOW-NOISE TRAVELING-WAVE TUBES.

Abstract

Research was continued on the design and development of low noise L-band traveling-wave tubes. The initial design considerations for the lownoise gun were developed. The S-band gun, which gave satisfactory performance, was scaled to L-band, and the calculated noise figure was less than 10 db from 1.0 gc to 2.6 gc. A broadband helix design was considered in terms of the conditions imposed by the required PPM focusing and broadband noise figure.
