Eine Wanderfeldröhre mit einer innerhalb einer metallisierten Vakuumhülle der Röhre untergebrachten wendelartigen Verzögerungsleitung und einer Anzahl parallel zueinander längs Mantellinien der Leitung angeordneten Halterungsstäben, die im Innenquerschnitt der Vakuumhülle in ihrer Lage fixiert sind, ist aus der DE-A-1 937 704 bekannt.DE-A-1 937 704 discloses a traveling wave tube with a helical delay line accommodated within a metallized vacuum tube of the tube and a number of support rods arranged parallel to one another along surface lines of the line and fixed in position in the inner cross section of the vacuum tube.
Darüber hinaus geht aus der DE-A-2 137 795 ein Wanderfeldklystron und ein Verfahren zur Herstellung des Wanderfeldklystrons als bekannt hervor. In den Resonatorkammern sind zur Erzielung einer ausgedehnten Wechselwirkung mit dem Elektronenstrahl Verzögerungsstrukturen vorgesehen, wobei zumindest die Verzögerungswendeln der ausgangsseitigen Leitungskammern über an ihrem Umfang verteilte massive Isolierelemente guter Wärmeleitfähigkeit an in durchgehende Gewindebohrungen in den Kammerwänden eingesetzte Schrauben gelötet sind. Bei diesem bekannten Verfahren wird die Wendel mit den daran angelöteten Isolierelementen mittels eines Zentrierdorns zur Achse der Resonatorkammer so zentriert, dass die Isolierelemente fluchtend zu den Achsen der Gewindebohrungen liegen, wobei in die Gewindebohrungen von aussen die Schrauben mit den eingesetzten Lotringen auf Anschlag mit den freien Enden der Isolierelemente eingeschraubt werden und an den Kontaktstellen Lotmaterial vorgesehen ist.In addition, DE-A-2 137 795 discloses a traveling field klystron and a method for producing the traveling field klystron as known. In order to achieve an extended interaction with the electron beam, delay structures are provided in the resonator chambers, with at least the delay coils of the output-side line chambers being soldered to solid screws of good thermal conductivity on screws inserted into continuous threaded holes in the chamber walls.

Da bei Wanderfeldröhren immer grössere Lei- . stungen gefordert werden, spielt auch das Problem der Wärmeableitung eine immer grössere Rolle.Because with hiking tubes there is more and more lei. The problem of heat dissipation also plays an increasingly important role.
Der Erfindung liegt die Aufgabe zugrunde, ein weniger aufwendiges und einfach durchführbares Verfahren zur Herstellung einer Wanderfeldröhre zu schaffen, um bei dieser Röhre die in der Verzögerungsleitung auftretende Wärme optimal über die Halterungsstäbe auf die massive Vakuumhülle abzuleiten.The invention has for its object to provide a less complex and easy to implement method for producing a traveling wave tube in order to optimally dissipate the heat occurring in the delay line in this tube via the mounting rods on the massive vacuum envelope.
Diese Aufgabe wird erfindungsgemäss durch ein Verfahren zur Herstellung einer Wanderfeldröhre mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved according to the invention by a method for producing a traveling wave tube with the features of claim 1.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand zusätzlicher Ansprüche 2 bis 6.Further advantageous embodiments of the invention are the subject of
Die Erfindung weist folgende Vorteile auf:The invention has the following advantages:
In die Vakuumhülle werden Bohrungen eingebracht, und zwar z. B. durch Bohren, Stanzen, Funkenerosion oder Ätzen. Die in ihrem Durchmesser vorzugsweise auf die Ring- bzw. Wendelbreite abgestimmten Halterungsstäbe können direkt oder nachdem sie durch ein gut wärmeleitendes Material verlängert worden sind, in die Bohrungen gesteckt, bis auf Anschlag eingeschoben und mit Spanndraht befestigt in die Vakuumhülle eingelötet werden. Es wird eine optimale Wärmeableitung von der Verzögerungsleitung zur Vakuumhülle erreicht.Holes are made in the vacuum envelope, for. B. by drilling, punching, spark erosion or etching. The diameter of the support rods, which are preferably matched to the width of the ring or coil, can be inserted into the bores directly or after they have been extended by a good heat-conducting material, pushed in as far as they will go and fastened into the vacuum envelope with tension wire. Optimal heat dissipation from the delay line to the vacuum envelope is achieved.
Die thermischen Ausdehnungsunterschiede zwischen den Halterungsstäben und der Vakuumhülle können, im Gegensatz zu bekannten Anordnungen mit längs zur Verzögerungsleitung verlaufenden Halterungsstäben, nicht wirksam werden. Ausserdem wird ein besserer Koppelwiderstand erreicht. Die Verzögerungsleitung kann als Wendel-, Ring-Steg- oder anderer Leitungsstruktur vorliegen.The thermal expansion differences between the support rods and the vacuum envelope, in contrast to known arrangements with support rods running along the delay line, cannot take effect. In addition, a better coupling resistance is achieved. The delay line can be in the form of a spiral, ring-bridge or other line structure.
Die optimale Wärmeableitung von der Verzögerungsleitung zur Vakuumhülle wird dadurch ermöglicht, dass zwischen Verzögerungsleitung und Halterungsstäben bzw. zwischen Halterungsstäben und Vakuumhülle eine einwandfreie Verbindung, vorzugsweise Lötverbindung, durchgeführt wird. Dies wird durch radial zur Verzögerungsleitung führende Halterungsstäbe (Isolierstäbe) erreicht (sogenannte Igeltechnik). Entsprechend der auftretenden Leistung kann eine Dreier- oder Vierer-Teilung gewählt werden.The optimal heat dissipation from the delay line to the vacuum envelope is made possible by a perfect connection, preferably a soldered connection, being carried out between the delay line and the support rods or between the support rods and the vacuum envelope. This is achieved by holding rods (insulating rods) leading radially to the delay line (so-called hedgehog technology). Depending on the performance occurring, a division of three or four can be selected.
Im einzelnen geschieht dies folgendermassen:In detail, this happens as follows:
Die z. B. aus Kupfer bestehende Vakuumhülle (Mantelrohr) wird entsprechend der Leitungssteigung (z.B. Wendelsteigung) in einer Dreier- oder Vierer-Teilung durchbohrt. Der Bohrungsdurchmesser richtet sich nach dem Durchmesser der Halterungsstäbe oder deren Verlängerungen. Die Löcher können ausser durch Bohren auch durch andere Verfahren eingebracht werden, z. B. durch Stanzen, Funkenerosion oder Ätzen. Entsprechend der Steigung der Löcher wird dann entlang der Vakuumhülle eine Vertiefung (Rille) eingestochen.The z. B. existing copper vacuum sheath (jacket tube) is pierced according to the line pitch (e.g. spiral pitch) in a three or four division. The bore diameter depends on the diameter of the support rods or their extensions. The holes can be made by other methods besides drilling, e.g. B. by punching, spark erosion or etching. Depending on the slope of the holes, a recess (groove) is then inserted along the vacuum envelope.
Die Halterungsstäbe, die vorzugsweise aus Aluminiumoxid, Berylliumoxid oder Diamant bestehen, sind im Durchmesser auf die Ring- bzw. Wendelbreite der Verzögerungsleitung abgestimmt. Die Halterungsstäbe können direkt oder nachdem sie durch ein gut wärmeleitendes Material (z.B. Kupfer) verlängert werden, in die Vakuumhülle eingelötet werden. Die Halterungsstäbe werden auf beiden Seiten metallisiert. Dafür kann sowohl das Mo Mg Si-, das TiMoCu- oder beliebig anderes Metallisierungsverfahren angewandt werden. Auf die Metallisierung wird anschliessend z. B. ca. je 10µrn Kupfer und Gold bzw. Nickel und Gold aufgetragen, welches als Lot dient. Das Aufbringen dieser Schicht kann z. B. galvanisch, durch Sputtern oder ein anderes Verfahren erfolgen. Die Verzögerungsleitung selbst kann aus Wolfram, Molybdän oder Kupfer hergestellt sein. Sollte die Verzögerungsleitung aus Molybdän oder Wolfram bestehen, wird sie mit einer Kupferschicht überzogen.The mounting rods, which are preferably made of aluminum oxide, beryllium oxide or diamond, are matched in diameter to the ring or spiral width of the delay line. The support rods can be soldered into the vacuum sleeve directly or after they have been extended by a good heat-conducting material (e.g. copper). The support rods are metallized on both sides. Mo Mg Si, TiMoCu or any other metallization process can be used for this. On the metallization z. B. approximately 10µrn copper and gold or nickel and gold, which serves as a solder. The application of this layer can e.g. B. galvanically, by sputtering or another method. The delay line itself can be made of tungsten, molybdenum or copper. If the delay line is made of molybdenum or tungsten, it is covered with a copper layer.
Die Montage der Verzögerungsleitung erfolgt zweckmässig in einer Montage-Lötlehre. Bei der Montage steht die Vakuumhülle mit der zentrisch gehaltenen Verzögerungsleitung senkrecht. Dann werden die Halterungsstäbe bzw. die Halterungsstäbe mit Verlängerung in die Bohrungen der Vakuumhülle gesteckt. Werden alle Halterungsstäbe (Isolierstäbe) bis auf Leitungsanschlag geschoben, sollten sie ca. 0,1 mm über den Kerndurchmesser der Gewinderille des Mantelrohres (Vakuumhülle) stehen. Anschliessend wird am Anfang befestigter Spanndraht mit ca. 0,2 mm Durchmesser über die überstehenden Halterungsstäbe in die Gewinderille gewickelt. Verwendung findet ein vergoldeter bzw. verkupferter Draht, der einen hohen Schmelzpunkt und vor allem einen geringen Ausdehnungskoeffizienten besitzt, d.h. vorzugsweise Molybdän oder Molybdän-Legierungen. Dabei ist auf die richtige Vorspannung des Drahtes zu achten. Wie am Anfang wird der Draht auch am Ende festgelegt. Entsprechend dem Spanndraht wird nun in die Rille ein Lotdraht gewickelt. Als Lot findet vorzugsweise Gold-Kupfer bzw. Gold-Nickel Verwendung. Das Lot zwischen Verzögerungsleitung und Halterungsstab bildet das zwischen den beiden Kupfer- bzw. Nickelschichten liegende Gold.The delay line is expediently installed in an assembly soldering gauge. During assembly, the vacuum envelope with the centrally held delay line is vertical. Then the support rods or the support rods with extension are inserted into the holes in the vacuum envelope. If all support rods (insulating rods) are pushed up to the line stop, they should be approx. 0.1 mm above the core diameter of the threaded groove of the jacket tube (vacuum sleeve). Then at the beginning Attached tension wire with a diameter of approx. 0.2 mm is wound into the thread groove via the protruding support rods. A gold-plated or copper-plated wire is used which has a high melting point and above all a low coefficient of expansion, ie preferably molybdenum or molybdenum alloys. Make sure that the wire is correctly pretensioned. As at the beginning, the wire is also fixed at the end. According to the tension wire, a solder wire is now wrapped in the groove. Gold-copper or gold-nickel is preferably used as the solder. The solder between the delay line and the support rod forms the gold lying between the two copper or nickel layers.
Nach der Montage von Anschlussflanschen sowie Ein- und Auskopplungen wird das ganze Gebilde im Lötofen auf ca. 960°C erhitzt. Durch die geringe Ausdehung des Spanndrahtes gegenüber der Verzögerungsleitung und den Halterungsstäben wird während des Lötprozesses das System zusammengehalten und die Lötung erfolgt unter einem bestimmten Druck. Bei richtiger Dimensionierung der Lotmenge bildet sich zwischen der Verzögerungsleitung und den Halterungsstäben eine leichte Lothohlkehle und am Mantelrohr werden die Halterungsstäbe innerhalb der Rille einschliesslich des Spanndrahtes mit Lot eingeschwemmt. Dieses vakuumdicht gelötete Mantelrohr stellt die Röhrenhülle, d.h. die Vakuumhülle, dar.After the installation of connection flanges and coupling and decoupling, the entire structure is heated to approx. 960 ° C in the soldering furnace. Due to the small expansion of the tension wire compared to the delay line and the support rods, the system is held together during the soldering process and the soldering takes place under a certain pressure. If the amount of solder is dimensioned correctly, a slight solder fillet is formed between the delay line and the support rods, and the support rods are washed in with solder on the casing tube within the groove, including the tensioning wire. This jacket tube, which is soldered in a vacuum-tight manner, provides the tube shell, i.e. the vacuum envelope.
Werden Halterungsstäbe mit Verlängerungen verwendet, kann die Mantelhülle (Vakuumhülle) auf einen genauen Aussendurchmesser abgedreht werden. Dieses Leitungsrohr kann dann in ein dünnes Mantelrohr oder in eine Polschuh integrierte Leitungshülle eingeschrumpft bzw. eingelötet werden.If mounting rods with extensions are used, the jacket (vacuum sleeve) can be turned to an exact outside diameter. This line tube can then be shrunk or soldered into a thin jacket tube or a line sleeve integrated into a pole piece.
