DEVELOPMENT OF LOW-NOISE TRAVELING-WAVE TUBES.
Abstract
Efforts were continued on the designs and development of low-noise, L-band, traveling-wave tubes. The mechanical design of the gun was completed with a 0.040-inch cathode design which will operate at 125 ma/sq. cm. A low dispersion helix design was begun, using a four-rod helix support structure. The helix impedance calculations were made for the purpose of the impedance transformer design. The calcu lated helix impedance is essentially independent of frequency at the 50-ohm level. (Author)
