DEVELOPMENT OF S-BAND LOW-NOISE PERIODIC PERMANENT MAGNET TRAVELING-WAVE TUBE

Abstract

The principal problem areas in the development of an S-band, low-noise, periodic, permanent magnet traveling-wave tube are discussed. Lens effects in the gun region are reduced by the use of larger anode apertures, contributing to improved operation in the 600-gauss field of a permanent magnet. A pin-seal input match was tested which might make possible a considerable reduction in total beam length. Magnets were designed for use in a reversed-field structure. A magnetic circuit for producing a PM-PPM field is described, and test results are cited. (Author)
