Efforts were continued on a program to design and develop a low-noise, multiple-function, X-band traveling-wave tube, for simultaneous operation as a linear X-band amplifier, limiter, and video detector in an electronic countermeasures system. The major effort during this period was expended in the evaluation of prototype tubes and focusing packages. The tubes fabricated were of glass or of hybrid glass-metal ceramic consturction in which only certain functions were evaluated, as well as metal ceramic structures in which all the proposed functions have been integrated. The evaluations have indicated that most of the design objectives can be met now and that any further ncessary design revisions can be best made in completely integrated tubes of metal ceramic construction. Meanwhile, improvements in metal ceramic technology, and the design refinements being made in the focusing structure and overall package design, are intended to simplify and increase the reliability of the proposed tube design.
