To solve the above problem, "in a delay line for transit time tubes to amplify • MilliKteterwaves, which consists of a waveguide , in which strip-shaped transverse webs are arranged alternately on opposite ends and galvanically connected to these, which up to an alternating space between one the line speed shaft and a treten- through openings in the transverse webs άΒη electron rich, according to the _-.? proposed that zv / ei longitudinal webs are arranged in the hollow conductor symmetrically with respect to the transverse webs extending from the waveguide Innenv / andung made to the Elevate the immediate proximity of the crossbars »

In the figures 1 to 3, 4 to 6 and 7 to 9 several thin metal sheets are shown, which are simply stacked or layered to produce the delay line and zJ. can be attached to one another by gold soldering. For this purpose, the thin metal sheets in the positions of FIGS. 1, 2 and 3 _S of FIGS. A, 5 and 6 or FIGS. 7? 8 and 9 are consequently stacked on top of each other until the ~
