ABSTRACT
Recent work at the University of New Mexico (UNM) by
Morelan~ et al. (1) has demonstrated how finite length
effects in a high power vacuum backward wave oscillator
(BWO) can be exploited to achieve frequency agility for
constant beam and magnetic field parameters. This
enhanced band~vidtll is obtained through the axial
displacement of the slow wave structure with respect to
the cutoff neck "inlet" to the electrodynamics system. This
paper describes the initial engineering design for
accomplishing this displacement automatically to
facilitate the incorporation of a robust controller, as
proposed by Abdallah, et a/. (2). The purpose of this
controller is to demonstrate a "smart tube" where a
variety of objectives, such as i) maximizing the frequency
bandwidth for a given constant power output, ii)
