Description

Die Erfindung betrifft eine Anordnung zur einstellbaren Halterung einer langgestreckten Wanderfeldverstärkerröhre, bei der die Zu- und Abführung der Hochfrequenzenergie über in axialer Richtung durch die Röhrenhülle hindurchgeführte Koaxialleitungsabschnitte erfolgt, mit einem die Röhre umgebenden magnetischen Kreis, der aus einem Magnetfelderzeuger und einem den Magnetfelderzeuger aufnehmenden Gehäuse besteht, das von einem weichmagnetischen Außenzylinder, einem dazu konzentrisch angeordneten und die Röhre in geringem Abstand umgebenden nichtmagnetischen metallischen Innenzylinder und zwei diese Zylinderanordnung stirnseitig abschließenden ringscheibenförmigen weichmagnetischen Endplatten gebildet ist.The invention relates to an arrangement for adjustable mounting an elongated traveling field amplifier tube, in which the supply and discharge of the High-frequency energy passed through the tube casing in the axial direction Coaxial line sections are made with a magnetic circuit surrounding the tube, that consists of a magnetic field generator and a housing accommodating the magnetic field generator consists of a soft magnetic outer cylinder, one concentric to it arranged and the tube at a small distance surrounding non-magnetic metallic Inner cylinder and two annular disk-shaped rings that terminate this cylinder arrangement on the end face soft magnetic end plates is formed.

Derartige Anordnungen sind grundsätzlich bekannt.Such arrangements are known in principle.

Aufgabe der Erfindung ist es, die Ausfluchtung der Magnetfeldachse mit der Strahlachse in einfacher Weise zu ermöglichen, da diese Achsen auf Grund der Fertigungstoleranzen nicht notwendig von vornherein ausgefluchtet sind und deshalb bei derartigen Anordnungen nach dem Einbau der Röhre üblicherweise ausgefluchtet werden.The object of the invention is to align the axis of the magnetic field to allow with the beam axis in a simple manner, since these axes due to the manufacturing tolerances are not necessarily aligned from the start and therefore usually aligned in such arrangements after the tube is installed will.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß jede der Endplatten einen ringförmigen Bund aufweist, der mit einstellbaren Halterungselementen versehen ist, die am zugehörigen Röhrenende anliegen und dieses quer zur Achse des magnetischen Kreises zu verschieben gestatten.This object is achieved according to the invention in that each of the End plates have an annular collar with adjustable support members is provided, which rest on the associated tube end and this transverse to the axis of the Allow magnetic circuit to move.

In der Zeichnung ist ein Ausführungsbeispiel der erfindungsgemäßen Anordnung im Längsschnitt dargestellt.In the drawing is an embodiment of the invention Arrangement shown in longitudinal section.

Der Magnetfelderzeuger kann entweder permanente Magnete oder - wie dargestellt - eine Spule 81 aufweisen. Der magnetische Kreis weist einen Innenzylinder 83 aus nichtmagnetischem Material, einen Außenzylinder 84 aus weichmagnetischem Material und ringscheibenförmige weichmagnetische Endplatten 85, 86 auf, die die Zylinderanordnung stirnseitig abschließen. Die Endplatte 85 weist einen ringförmigen Bund 88 auf und trägt drei oder vier Schrauben 89, um die Röhre in dem magnetischen Kreis einstellbar zu halten. Vorzugsweise sind Anschlagscheiben 90 an den Schrauben 89 angebracht, um einen besseren Kontakt mit den Kühlrippen 77 der Auffangelektrode der Röhre herzustellen. Der Bund 88 ist mit vier Öffnungen 91 versehen, um einen freien Fluß der Kühlluft zu ermöglichen und die Befestigungsbolzen 80 an dem linken Ende des Kühlers zugänglich zu machen.The magnetic field generator can either have permanent magnets or, as shown, a coil 81 . The magnetic circuit has an inner cylinder 83 made of non-magnetic material, an outer cylinder 84 made of soft magnetic material and annular disk-shaped soft magnetic end plates 85, 86 which close off the cylinder arrangement at the end. The end plate 85 has an annular collar 88 and carries three or four screws 89 to adjustably hold the tube in the magnetic circuit. Preferably, stop washers 90 are attached to screws 89 for better contact with the cooling fins 77 of the tube's collecting electrode. The collar 88 is provided with four openings 91 to allow a free flow of the cooling air and to make the fastening bolts 80 accessible at the left end of the cooler.

Die Endplatte 86 weist ebenfalls einen ringförmigen Bund 93 auf, welcher eine nichtmagnetische zylindrische Ausfütterung 94 hat. Diese Ausfütterung trägt drei oder vier Stellschrauben 95 zur Halterung ; und Querverschiebung des strahlerzeugerseitigen Röhrenendes, und der Bund 93 ist mit Öffnungen 96 versehen, damit die Stellschrauben 95 zugänglich sind. Das Ende des Bundes 93 ist mit einem Gewinde versehen, um eine mit einem Flansch versehene Kappe 97 abnehmbar anzubringen, welche die Röhre an den magnetischen Kreis in axialer Richtung andrückt.The end plate 86 also has an annular collar 93, which has a non-magnetic cylindrical liner 94. This lining carries three or four set screws 95 for mounting; and lateral displacement of the jet generator side Tube end, and the collar 93 is provided with openings 96 so that the set screws 95 are accessible. The end of the collar 93 is threaded to a flanged cap 97 detachably attaching the tube to it presses the magnetic circuit in the axial direction.

Um eine feste Unterstützung für die Röhr über die ganze Länge des Röhrenteiles mit verringertem Durchmesser vorzusehen, ohne die leichte radiale Einstellung der Röhre relativ zum magnetischen Kreis mittels der Schrauben 89 und 95 zu beeinträchtigen, ist ein schmaler Hohlraum zwischen der Außenseite der Röhre und der Innenseite des nichtmagneitschen Innenzylinders 83 vorgesehen. Dieser Raum ist mit einem elastischen @ verformbaren Material 101, wie beispielsweise Silikongummi, gefüllt, welches sich bei' Betätigung der Schrauben etwas deformiert und damit die Röhre elastisch unterstützt. Das elastische Material ist von einer nichtmagnetischen Muffe 98 umschlossen, welche strahlerzeugerseitig einen an der Röhre befestigten Endflansch 100 aufweist, und ist zusammen mit der Muffe 98 mit der Röhre aus dem Zylinder 83 herausziehbar. Die Gummifüllung ist also in dem Raum zwischen Röhre und Muffe 98 angebracht. Die nichtmagnetische Ausfütterung 94 wird aus demselben Grunde wie die Muffe 98 mit der Röhre entfernt.In order to provide firm support for the tube over the entire length of the reduced diameter tube section without affecting the easy radial adjustment of the tube relative to the magnetic circuit by means of screws 89 and 95, there is a narrow cavity between the outside of the tube and the inside of the non-magnetic inner cylinder 83 is provided. This space is filled with an elastic, deformable material 101, such as, for example, silicone rubber, which deforms somewhat when the screws are actuated and thus elastically supports the tube. The elastic material is enclosed by a non-magnetic sleeve 98, which has an end flange 100 attached to the tube on the jet generator side, and can be pulled out of the cylinder 83 together with the sleeve 98 with the tube. The rubber filling is thus placed in the space between the tube and the sleeve 98. The non-magnetic liner 94 is removed with the tube for the same reason as the sleeve 98.
