Abstract

The travelling wave tube has a delay winding that is produced of a rare earth oxide micro alloyed molybdenum material with the rare earth component being present between 0.05 and 1 percent by weight. The rare earth dioxide can be in the form of Lanthanum oxide. The production of the coil using the material is effected using normal techniques.

Description

Die Erfindung betrifft eine Wanderfeldröhre mit einer Laufzeitwendel aus einem Molybdän-Werkstoff, wie sie aus der DE 41 12 175 A1 bekannt ist.The invention relates to a traveling wave tube with a Runtime helix made of a molybdenum material, such as the DE 41 12 175 A1 is known.

Bei Wanderfeldröhren sind als Verzögerungsleitungen einge­ setzte Laufzeitwendeln hohen thermischen Belastungen aus­ gesetzt. Als Werkstoff für solche Laufzeitwendeln wird ty­ pischerweise Wolfram oder reines Molybdän eingesetzt.In traveling wave tubes are used as delay lines exposed helixes to high thermal loads set. Ty typically tungsten or pure molybdenum is used.

Aufgabe der vorliegenden Erfindung ist es, die Eigenschaf­ ten von Wanderfeldröhren mit Laufzeitwendeln weiter zu verbessern, insbesondere hinsichtlich des Langzeitverhal­ tens bei hochbelasteten Röhren. The object of the present invention is the property of traveling wave tubes with helixes improve, especially with regard to long-term behavior tens of tubes.  

Die Erfindung ist im Patentanspruch 1 angegeben. Die Un­ teransprüche enthalten vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung.The invention is specified in claim 1. The Un Claims contain advantageous refinements and Developments of the invention.

Die Erfindung ist vorteilhaft insbesondere hinsichtlich der für Laufzeitwendeln anwendungsspezifisch günstigen Ei­ genschaften des gewählten Werkstoffs, derThe invention is particularly advantageous in terms of the egg that is application-specific and affordable for maturity coils properties of the selected material, the

  • a) eine gute Duktilität zeigt, die auch nach einer Rekristallisation weitgehend erhalten bleibta) shows good ductility, even after one Recrystallization remains largely intact
  • b) eine hohe Kriechbeständigkeit bei den üblichen Be­ triebstemperaturen in hochbelasteten Röhren zeigtb) a high creep resistance in the usual loading shows operating temperatures in highly loaded tubes
  • c) eine hohe Warmfestigkeit aufweistc) has a high heat resistance
  • d) ausgezeichnete (uneingeschränkte) Vakuumtauglich­ keit besitztd) excellent (unrestricted) vacuum capability possesses
  • e) problemlose Schweißbarkeit nach üblichen Verfahren ermöglicht.e) problem-free weldability according to usual methods enables.

Der Werkstoff nach dem Anspruch 1 wird in den vor­ stehend genannten Eigenschaften teilweise von den Werk­ stoffen gebräuchlicher Laufzeitwendeln übertroffen, z. B. durch geglühtes Wolfram mit sehr hoher Warmfestigkeit. Wolfram ist aber aufgrund geringer Duktilität ungünstig für das Wickeln der Wendeln. Der mit Seltenerdoxid mikro­ legierte Molybdänwerkstoff zeigt hingegen in allen wesent­ lichen Anforderungen für Laufzeitwendeln in Wanderfeldröh­ ren, insbesondere auch in den besonders belasteten Endbe­ reichen der Wendeln gute Eigenschaften wie vorstehend be­ reits aufgeführt.The material according to claim 1 is in the before properties mentioned in part from the factory substances of common term coils exceeded, e.g. B. through annealed tungsten with very high heat resistance. However, tungsten is unfavorable due to its low ductility for winding the coils. The micro with rare earth oxide alloyed molybdenum material, however, shows in all essentials requirements for runtime coils in Wanderfeldröh ren, especially in the particularly stressed endbe  the helixes have good properties as above already listed.

Bevorzugt wird Lanthanoxid LaO als Seltenerdoxid einge­ setzt. Der Anteil des Seltenerdoxids beträgt vorteilhafterweise zwischen 0,05 und 1 Gewichtsprozent, vorzugsweise zwischen 0,2 und 0,5 Gewichtsprozent. Für Le­ gierungen mit Zusatzstoffanteilen in dieser Größenordnung hat sich neben Legierung und Dotierung der Begriff Mikro­ legierung durchgesetzt. Die Herstellung der Laufzeitwendel erfolgt in an sich bekannter Weise durch Wickeln eines Drahtes, der wiederum nach gängigen Verfahren der Metall­ urgie aus den angegebenen Bestandteilen Molybdän und Sel­ tenerdoxid erzeugt werden kann.Lanthanum oxide LaO is preferably used as rare earth oxide puts. The proportion of rare earth oxide is advantageously between 0.05 and 1 percent by weight, preferably between 0.2 and 0.5 percent by weight. For Le Alloys with proportions of additives of this size In addition to alloy and doping, the term micro alloy enforced. The production of the term helix takes place in a manner known per se by winding one Wire, which in turn uses common metal processes urgie from the specified components molybdenum and sel can be generated.
