Description

Die Erfindung bezieht sich auf eine elektrische Entladungsröhre mit einem Hohlraumresonatör, der, über einen Kreisumfang durch ein von einer ringförmigen Kathode erzeugtes Elektronenbündel erregt wird.The invention relates to an electric discharge tube with a cavity resonator, which, over a circumference through one of an annular Electron beam generated cathode is excited.

Bei den bekannten Röhren der vorerwähnten Art wird die erzeugte Energie nach außen unter Zuhilfenahme einer in eine gleichachsige Leitung Tiber- , gehenden Koppelschleife abgeführt.In the known tubes of the aforementioned type, the energy generated to the outside with the help of a Tiber pipe running on the same axis Coupling loop discharged.

Der Nachteil der Verwendung von Koppelschleifen" bei diesen Röhren mit verhältnismäßig hohen Energien ist der, daß die Koppelschleife leicht durch=: brennt, und auch, daß die Kopplung mit dem Hoh.lfraumresonator nicht genügend fest ist.The disadvantage of using coupling loops "with these tubes with relatively high energies it is that the coupling loop easily through =: burns, and also that the coupling with the cavity resonator is not sufficiently tight is.

Bei einer elektrischen Entladungsröhre mit einem: Hohlraumresonator, der über einen Kreisumfang von einem durch eine ringförmige Kathode erzeugten Elektronenbündel erregt wird, wird die erzeugte Energie gemäß der Erfindung mittels eines Systems gleichachsiger Leiter abgeführt, die im Innern des Hohlraumresonators in zwei parallel liegende Platten übergehen, die mit Öffnungen zum Durchlaß des Elektronenbündels versehen sind. Auf diese Weise ergibt sich eine besonders feste Kopplung zwischen den gleichachsigen Abnahmeleitern und dem Schwingungssystem, wobei hohe Energiewerte über dieses Abnahmesystem abgeführt werden können.In the case of an electrical discharge tube with a: cavity resonator, over the circumference of an electron beam generated by an annular cathode is excited, the generated energy is according to the invention by means of a system equiaxed conductors discharged inside the cavity resonator in two parallel Pass over lying plates, those with openings for the passage of the electron beam are provided. In this way, there is a particularly strong coupling between the coaxial acceptance ladders and the vibration system, with high energy values can be discharged via this acceptance system.

Die Erfindung wird nachstehend an Hand der Zeichnung näher erläutert, in der Fig. i ein Längsschnitt des Elektrodensystems einer Röhre nach der Erfindung, Fig. 2 ein Schnitt senkrecht zur Achse des Elektrodensystems ist.The invention is explained in more detail below with reference to the drawing, in Fig. i a longitudinal section of the electrode system of a tube according to the invention, Figure 2 is a section perpendicular to the axis of the electrode system.

In den Figuren bezeichnet i einen flachen, zylindrischen Hohlraumresonator, der mit zwei kreisförmigen, durch eine Anzahl von Streifen 13 überbrückten Öfnungeü i-2 versehen ist. 1?ineKathode 2 emittiert ein kreisförmiges @lcktroncnhündel zur Reflexionselektrode 3 durch die Üffnungcn 12 hindurch. Das von der Kathode kommende Elektronenbündel wird von zwei F3iincIclclekti-oden a und 5 gerichtet. Im Innern des Hohlraumresonators sind zwei kreisförmige Platten 6 Lind 7 angeordnet, die auch mit kreisförmigen Üffnungen 12 versehen sind, die durch Streifen t i überbriickt sind. Mit den "Platten 6 und 7 sind der Außen- und Innenleiter S biw. 9 eines gleichachsigen Leitersystems vcrbunden. Der Block io aus Metall und i i aus Isoliermaterial dient zum Aufrechterhalten des richtigen gegenseitigen Abstandes zwischen den vers; hiedrnen Einzelteilen des Systems. Der Block io hat den gleichen Durchmesser wie die Leitung B. Die beschrieben(- Röhre kann nach Art eines Reflcxklystrons @virksam sein, bei dem die Platten 6 und ; gemeinsam mit dem Hohlrauinresonator i das Schwingungssystem bilden.In the figures, i denotes a flat, cylindrical cavity resonator, the one with two circular openings bridged by a number of strips 13 i-2 is provided. 1? IneKathode 2 emits a circular tube for the Reflection electrode 3 through the openings 12. The one coming from the cathode The electron beam is directed by two functions a and 5. At the inside of the cavity resonator two circular plates 6 and 7 are arranged, which also are provided with circular openings 12, which are bridged by strips t i are. The outer and inner conductors S and 9 are coaxial with the plates 6 and 7 Ladder system connected. The block io made of metal and i i made of insulating material is used to maintain the correct mutual spacing between the verses; bow down Individual parts of the system. The block io has the same diameter as the pipe B. The described (- tube can be effective in the manner of a Reflcxklystons @ which the plates 6 and; together with the cavity resonator i the oscillation system form.
