The efficiency of a travelling wave tube is improved by the provision of a resonance section having a decreased delay interval with regard to the normal delay interval of the delay line of the tube. The resonance section is interposed in the delay line at the collector-side end of the delay line in such a manner that reflecting impact points are present at its ends and that at a medium operational frequency of lambda o the length of the resonance section is 1 = n lambda L/2. |
