Description

Die Erfindung betrifft eine Elektronenröhre mit axialsyinmetrischer Elektrodenanordnung und isst gekennzeichnet,durcheinon Topfmagneten, zwischen dessen Polen die Elektrodenanordnung koaxial angeordnet ist.The invention relates to an electron tube with an axially symmetrical Electrode arrangement and eats characterized by one pot magnet, between its Poles, the electrode arrangement is arranged coaxially.

Durch die Erfindung werden Abweichungen der Elektronen von ihren radialen Bahnen weitgehend vermiecieii. Dies ist besonders wichtig für Röhren mit stark positiv vorgespannten, gitterförmigen Elektroden, z. B. Ultrakurzwellenröhren mit Influenzauskopplung, bei denen,diese Elektroden einen möglichst geringen Strom aufnehmen sollen. Bissher war eine Elektronenbündelung durch ein Magnetfeld., und zwar ein magnetisches Längsfeld, lediglich für einen einzigen linearen Strahl bekannt.The invention eliminates deviations of the electrons from their radial Orbits largely vermiecieii. This is especially important for tubes with strong positive biased, grid-shaped electrodes, e.g. B. Ultra-short wave tubes with induction decoupling, for those who want these electrodes to absorb the lowest possible current. Bissher was a concentration of electrons by a magnetic field., namely a magnetic longitudinal field, known only for a single linear ray.

Ein Ausführungsbeispiel der Erfindung zeigt die Abhil.dung an Hand einer im Querschnitt dargestellten Ultrakurzwellenröhre. Die Ele.ktrodenanordnung besteht aus der als Hohlzylinider ausl;ebildeten und etwa indirekt geheizten Kathode K, vier wendelförmigen Gittern G,, G=, G3, G4 und der zylindrischen Auffangelektrode A. Die Elektroden; anordnung befindet sich iimerhallb einer ebenfalls zylindrischen und mit einer durchgehenden, z_vliiidrischen üffnung versehenen Glashülle H.An embodiment of the invention shows the remedy on hand an ultra-short wave tube shown in cross section. The electrode arrangement consists of the cathode, which is designed as a hollow cylinder and is indirectly heated K, four helical grids G ,, G =, G3, G4 and the cylindrical collecting electrode A. The electrodes; arrangement is iimerhallb also a cylindrical one and with a continuous, z_vliiidrischen opening provided glass envelope H.

Die Röhre ist derart zwischen den Polen des zweiteiligen zylindrischen Topfmagneten 31 angeordnet, daß der Innenteil S-S des Topfrna,gneten die Glashülle und,die Elektrodenanor@dnung koaxial durchsetzt, während der Außenzylinder N-N des Topfmagneten die Röhre koaxial umgibt. Es entsteht dann ein radiales magnetisches Feld, welches die Elektronen in genau radiale Bahnen zwingt.The tube is so between the poles of the two-part cylindrical Pot magnets 31 arranged that the inner part S-S of the Potfrna, gneten the glass envelope and, the electrode arrangement @ extension coaxially penetrates, while the outer cylinder N-N des Pot magnet surrounds the tube coaxially. Then a radial magnetic arises Field which forces the electrons into exactly radial paths.

Jedes der beiden Gitterpaare G1, G2 bzw. G3, G4 dient als eine Influenzauskopplungsvorrichtung und ist, ähnlich wie bei dem sogenannten Klystron, mit den irden der Schwingkreise S bzw. S' leitend verbunden. Die Schwingkreise können als Hohlraunischwinger ausgebildet und gegebenenfalls innerhalb der Röhre angeordnet scin. Sie sind zur Erzielung einer Rückkopplung in passender Weise miteinandergekoppelt. Gleichspannungsmäßigliegen die Gitter .auf stark positivem, die Ablenkelektrode A auf schwächer positivem Potential.Each of the two grid pairs G1, G2 or G3, G4 serves as an influence decoupling device and is, similar to the so-called klystron, with the earthen of the oscillating circles S or S 'conductively connected. The oscillating circuits can be designed as hollow brown oscillators and optionally arranged within the tube scin. You are about to achieve a Feedback coupled together in a suitable manner. In terms of DC voltage the grid on a strongly positive potential, the deflection electrode A on a weaker positive potential.

Infolge cLr genau radialen Elektronenbahn ist die Stromaufnahme der Gitter gering, insbesondere dann, wenn gemäß der Abbildung sdie Anordnung so getroffen wird, daß die der Kathode entfernter liegenden Gitter genau im Elektronenschatten der näher gelegenen Gitter liegen. Gegebenenfalls kann vor dem ersten Gitter G, noch ein weiteres nur schwach positiv adkr sogar negativ vorgespanntes Gitter G5 angeordnet sein, welches .die Elektronen abstößt und dadurch einen Elektronenschatten für die Gitter G, bis G4 erzeugt.As a result of cLr exactly radial electron orbit, the current consumption is the Lattice low, especially if the arrangement is made in accordance with the illustration that the grid more distant from the cathode is exactly in the electron shadow of the nearer grids. If necessary, in front of the first grid G, yet another only weakly positive adkr even negatively biased grid G5 be arranged, which repels the electrons and thereby creates an electron shadow for the grids G, to G4 generated.
