Abstract
A delay line for traveling wave tubes comprises a rectangular wave guide having cross members which perpendicularly protrude into the wave guide interior extending alternately from two sides facing each other of a first pair of inner wave guide walls. The wave guide inner wall includes a recess extending in the longitudinal direction of the wave guide and disposed symmetrically at both sides of the longitudinal extension of the cross members, at least in the area of their ends. Such a delay line construction provides for the provision of a magnet surrounding the line which may have a comparably small inside diameter.
