Description

Die Erfindung betrifft eine Laufzeitröhrenanordnung für ultrakurze Wellen, bei der ein in seiner Geschwindigkeit gesteuerter Elektronenstrahl nach dem Durchlaufen eines zur Umwandlung der Geschwindigkeitsmodulation in eine Dichtemodulation ,dienenden Laufraumes durch ein von zwei aufeinanderfoigenden Elektroden gebildetes Auskoppelsystem hindurchtritt. Erfindungsgemäß sind an der Auskoppelstelle außer dem r_A.uskoppelsystem für die Grundwelle ein oder mehrere Auskoppelsysteme mit auf eine Oberwelle der zu erzeugenden Grundschwingung abgestimmten Schwingkreisen angebracht. Eine derartige Anordnung ist in der Figur schematisch dargestellt. In dieser bedeutet i die Kathode, 2 und 3 .die beiden Elektroden, die zur ,Geschwindigkeitsmodulation des Elektronenstrahles dienen. An die beiden Steuerelektroden ist der Hohlraumresonator q. angeschlossen. Mit 5 ist der Laufraum bezeichnet, innerhalb dessen die Geschwindigkeitsmodulation des Strahles in eine Dichtemodulation umgewandelt wird. -Arn Ende des Laufraumes 5 befindet sich er Auskoppelraum 6 für die Grundwelle, welcher durch die Elektroden 7 und 8 begrenzt ist und mit einem Hohlraumschwingkreis 9 verbunden ist. Außer dem Auskoppelraum 6 ist nun noch ein weiterer Auskoppelraum io vorgesehen, der einerseits durch die Elektrode 7, andererseits durch die Elektrode i i begrenzt wird und ebenfalls zu einem Hohlkreis 12 ergänzt ist. Dieser Kreis ist auf eine Oberwelle der zu erzeugenden Grundwelle abgestimmt. Es hat sich gezeigt, daß es auf diese Weise gelingt, auch Oberwellen aus dem Elektronenstrahl zu entnehmen, da der dichtemodulierte Strahl, wie eingehende Überlegungen zeigen, nicht nur die Grundwelle, sondern auch Oberwellen anzuregen vermag. Diese Oberwellen können zu den verschiedensten Zwecken verwendet werden, und es ist möglich, bei einer Laufzeitröhre nicht nur eine, sondern auch mehrere Oberwellen neben -der Grundwelle aus dem Strahl zu entnehmen. Dies kann beispielsweise bei der Trägerfrequenzübertragung sehr vorteilhaft sein und eine Vereinfachung der Gesamtanordnung mit sich bringen.The invention relates to a time-of-flight tube arrangement for ultrashort Waves, in which an electron beam controlled in its speed follows passing through a to convert the speed modulation into a density modulation , serving running space formed by two consecutive electrodes Decoupling system passes. According to the invention, except at the decoupling point the r_A. Resonant circuits tuned to a harmonic of the fundamental oscillation to be generated appropriate. Such an arrangement is shown schematically in the figure. In this means i the cathode, 2 and 3 .the two electrodes that are used for the speed modulation serve the electron beam. The cavity resonator is attached to the two control electrodes q. connected. With 5 the running space is referred to, within which the speed modulation of the beam is converted into a density modulation. -Arn the end of the walking area 5 is the decoupling space 6 for the fundamental wave, which is through the electrodes 7 and 8 is limited and is connected to a resonant cavity circuit 9. Aside from that Auskoppelraum 6 is now a further Auskoppelraum io provided, on the one hand by the electrode 7, on the other hand by the electrode i i and likewise is added to a hollow circle 12. This circle is on a harmonic of the to be generated Fundamental wave tuned. It has been shown that it works this way, too To take harmonics from the electron beam, since the density-modulated beam, As detailed considerations show, not only the fundamental wave, but also harmonics able to stimulate. These harmonics can be used for a variety of purposes and it is possible with a transit time tube not only one, but also several harmonics besides the fundamental can be found in the beam. This can for example, be very advantageous in carrier frequency transmission and a Bring simplification of the overall arrangement.

Jeder der Hohlräume der Röhre ist mit j e einer Koppelschleife 13 bzw. 1q. bzw. 15 versehen. Die Anregung des ersten Hohlraumes d. kann durch Rückkopplung aus dem Auskoppelraum 9 oder aber auch durch Fremdsteuerung erfolgen.Each of the cavities of the tube is connected to a coupling loop 13 or 1q. or 15 provided. The excitation of the first cavity d. can through feedback from the decoupling space 9 or also by external control.
