Description

Elektronenröhre, deren Vakuumgefäß im wesentlichen aus einem keramischen Hohlkörper besteht, der auf der Innenseite eine metallische Auflage besitzt Die Erfindung betrifft eine Elektronenröhre, die insbesondere zur Erzeugung und Verstärkung elektrischer Schwingungen hoher Frequenz (Wellenlänge von der Größenaa.-ordnung io m und darunter) und großer Leistung geeignet ist.Electron tube, whose vacuum vessel consists essentially of a ceramic There is a hollow body, which has a metallic coating on the inside The invention relates to an electron tube, which is particularly used for generation and amplification electrical oscillations of high frequency (wavelength of the order of magnitude io m and below) and great performance.

Es sind bereits Entladungsgefäße aus keramischen Massen bekannt. Auch hat mau schon Wasserwiderstände für wassergekühlte Hochleistungsröhren in Form einer Rohrschlange aus Steinzeug hergestellt.Discharge vessels made from ceramic masses are already known. Even Mau already has water resistances for water-cooled high-performance tubes in the form of a Coiled pipe made from stoneware.

Ferner sind innenmetallisierte Entladungsröhren- aus Glas bekannt, bei denen eine InnenmetalIisierung als Elektrode dient. Bei Vakuumgefäßen für Entladungsröhren, die im wesentlichen aus einem keramischen Hohlkörper bestehen, der eine Innenmetallisierung besitzt, werden nun gemäll der Erfindung in, dessen Wand zur Durchleitung eines Kühlmittels geeignete Kanäle vorgesehen und wird dem Hohlkörper eine solche Gestalt gegeben, daß er einen H-förmigen Längsschnitt besitzt, wobei auch die über den Boden hinausragenden Teile der Seitenwand mit Kanälen versehen werden.Furthermore, internally metallized discharge tubes made of glass are known, in which an internal metallization serves as an electrode. In the case of vacuum vessels for discharge tubes, which essentially consist of a ceramic hollow body with an internal metallization owns, are now according to the invention in, the wall for the passage of a Suitable channels are provided for coolant and the hollow body is given such a shape given that it has an H-shaped longitudinal section, which is also across the floor protruding parts of the side wall are provided with channels.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. H bedeutet den keramischen Hohlkörper. Er trägt an seiner Innenwand einen Metallbelag M, der als Anode verwendbar ist und gleichzeitig einen Schutz, gegen das Durchsickern von Gasen oder Flüssigkeiten durch Gefügefehler in der keramischen Masse bildet. Zwecks Kühlung ist der keramische Hohlkörper H mit Innenmetallisierung erfindungsgemäß mit Kanälen L versehen, durch die ein Kühlmittel geleitet werden kann. Der keramische Körper H besitzt gemäß der weiteren Erfindung in seinem Längsschnitt ' eine H-förmige Gestalt, die es einerseits gestattet, den aus Glas oder Metall bestehenden und im letzteren Fall gleichzeitig als Anodenzuleitunverwendharen Pumpstutzcn P am Boden Q anzuordnen, so daß er mechanisch geschützt ist, und andererseits den Kühlwc-` zu verlängern, so daß der Widerstand der Wasserstrecke heraufgesetzt wird. Gleichzeitig wird dadurch eine verbesserte Kühlung des Bodens Q bewirkt. Zum Schutz gegen mechanische Beschädigung ist der Pt;mpsttitzuii mit einer VerguPmasse V' umgeben. Die Zuleitung zu Glühkathode und Gitter c rfijlgt an der oberen Seite des keramischen Hohlkörpers H durch Zuführtmgeit I@ und G. Zweckmäßig besteht der Teil J des Vakuumgefäl.')es, der von den Elektroden durchsetzt wird, aus Glas.An embodiment of the invention is shown in the drawing. H means the ceramic hollow body. It has a metal covering on its inner wall M, which can be used as an anode and at the same time a protection against leakage of gases or liquids due to structural defects in the ceramic mass. For the purpose of cooling, the ceramic hollow body H with internal metallization is according to the invention provided with channels L through which a coolant can be passed. The ceramic According to the further invention, the body H is H-shaped in its longitudinal section Shape that on the one hand allows the glass or metal and im the latter case at the same time as an anode feeder pump stubs P on the bottom that cannot be used Q to be arranged so that it is mechanically protected, and on the other hand the Kühlwc-` to lengthen, so that the resistance of the waterway is increased. Simultaneously an improved cooling of the floor Q is thereby effected. To protect against mechanical Damage is the Pt; mpsttitzuii with a sealing compound V '. The supply line to the hot cathode and grid c rfijlgt on the upper side of the ceramic hollow body H by supplying I @ and G. It is practical if part J of the vacuum gradient exists, which is penetrated by the electrodes, made of glass.
