Description
Für sehr kürze elektromagnetische Wellen im Bereich der Zentimeter- und Dezimeterwelle sind Os.zilla,toren bekanntgeworden;, deren Schwingungen mittels einer Magnetfeldröhre angeregt werden., die mit einem veränderlichen Lechersystcm als abstimmbarer Schwingkreis, gekoppelt sind. Derartige Schwingungserzeuger sind in einem Hohlraum angeordnet worden, um die unkontrollierte: Abstrahlung von Sch`v ingungsenergie zu verhindern. Die Entnahme der Schwingungen erfolgt vielmehr mittels in den Hohlraum eingeführter Energieleitungen, die z. B. aus konzentrischen Leitungen bestehen können, deren Mantel mit dem metallischen Gehäuse des Hohlraumes verbunden ist, in dessen Inneres der Innenleiter des Kabels hineinragt. Auf dem Lechersystem bilden sich stehende Wellen aus, deren Energie je nach der Kopplung des Innenleiters der Energieleitung emtnehmbar ist und irgendwelchen Meßanordnungen oder dem Mischteil eines. Überlagerungsempfängers zugeführt wird. Bei der Änderung der Abstimmung wird die Lage der stehenden Welle zum Innenleiter des konzentrischen Kabels geändert, so daß der Grad der Ankopplung von der Abstimmung abhängig ist. Es ist jedoch erwünscht, daß die abnehmbare Energie über den ganzen REgelbeTeich des Oszill'ators konstant bleibt.For very short electromagnetic waves in the range of centimeter and decimeter waves are known as Os.zilla, toren, whose vibrations by means of a magnetron., which with a variable Lechersystcm are coupled as a tunable resonant circuit. Such vibrators are been placed in a cavity to avoid the uncontrolled: radiation of Sch`v to prevent ing energy. Rather, the vibrations are extracted by means of introduced into the cavity power lines, which z. B. from concentric lines can exist whose jacket is connected to the metallic housing of the cavity is, in the interior of which protrudes the inner conductor of the cable. On the Lechersystem standing waves are formed, the energy of which depends on the coupling of the inner conductor the power line and any measuring arrangements or the mixing part one. Heterodyne receiver is supplied. When changing the vote will changed the position of the standing wave to the inner conductor of the concentric cable, so that the degree of coupling depends on the vote. However, it is desirable that the removable energy is constant over the whole area of the oscillator remain.
Eine vorteilhafte Lösung für die vorgenannte Aufgabe besteht bei Schwingungserzeugern der beschriebenen Art darin, daß die Energieentnahme mittels der Polschuhe des Feldmagneten der Magnetfeldröhre erfolgt. Die Polschuhe befinden sich stets im Spannungsmaximum der sich auf dem Lechersystem ausbildenden stehenden Welle, so daß sie ein ideales Mittel zur Auskopplung einer stets gleichen Energiemenge der erzeugten Schwingungen bilden. Die Polschuhe stellen. gewissermaßen einen Dipol dar; an den[ die Energieleitung zur Auskopplung der Schwingungen angeschlossen ist.An advantageous solution to the above-mentioned object is given by vibration generators of the type described in that the energy extraction by means of the pole pieces of the field magnet the magnetron. The pole shoes are always at the maximum tension the standing wave forming on the Lechersystem, so that it is an ideal Means for coupling out a constant amount of energy from the generated vibrations form. Put the pole shoes. to a certain extent represents a dipole; to the [the power line is connected to decouple the vibrations.
Eine Ausführung der Erfindung ist in der Zelichnung dargestellt.An embodiment of the invention is shown in the drawing.
Mit i ist eine, Magnetfell!dröhre bezeichnet, in deren Innern Lecherleiter 2 angeordnet und an das Anodensystem angeschlossen sind. Mittels des äußeren., kapazitiv an diese Leiter angekoppelten Lechersystems 3 läßt sich die von, der Magnetfeldröhre i erzeugte, sehr kurze Welle ändern. Dazu dient ein zwischen den Leitern, 3 des. äußeren Lechers.yste@ms verstellbarer kolbenartiger Kurzschlußschieber 4. Die Anordnung befindet sich innerhalb: eines Gehäuses 5, das. auch. den Feldmagneten 6 der Magnetfeldröhre i aufnimmt. Die Polschuhe 7 des Magneten 6 sind in der Achse des Anodensystems, der Magnetfeldröhre angeordnet und befinden sieh, daher, wie.. bereits erwähnt, stets, im Spannungsbauch der sich auf dem Lechersystem aus den Leitern 2 und, 3 bildenden stehenden Welle. Infolgedessen. können sie, zur konstanten Ankopplung der zur Energieentnahme dienenden konzeintrischen Leitung 8 benutzt werden, deren Innenleter an den einen Polschuh z. B. bei 9 angeschlossen ist, während der metallische Mantel mit dem anderen Polschuh bei io verbunden, ist. Wie erkennbar ist, befinden sieh die Anschlußstellzn dicht an den der Magnetfeldröhre gegenüberstehenden Stirnseiten der Polschuhe.With i is a "Magnetfell! Tube" denotes, inside of which Lecher ladder 2 are arranged and connected to the anode system. By means of the outer., Capacitive Lechersystems 3 coupled to this conductor can be seen from the magnetron i generated very short wave change. This is done by a between the conductors, 3 des. outer Lechers.yste@ms adjustable piston-like short-circuit slide 4. The arrangement is located inside: a housing 5, the. also. the field magnet 6 of the magnetron i picks up. The pole pieces 7 of the magnet 6 are in the axis of the anode system, the magnetron tube and are located, therefore, as .. already mentioned, always, in the belly of tension on the Lechersystem made up of conductors 2 and 3 forming standing wave. Consequently. they can, for constant coupling the concentric line 8 serving for energy extraction are used, whose Inner leter to the one pole piece z. B. connected at 9, while the metallic Jacket is connected to the other pole piece at io. As can be seen, are located see the connection position close to the end faces opposite the magnetron the pole shoes.
