Description
ber zur Abstimmung, die hier in dieser Zeichnung der Übersichtlichkeit halber weggelassen sind. In den evakuierten Resonatorteilen sind die Wechselwirkungsräume 13,14,15 und 16 angeordnet, deren letzter 16 auch als sogenannter Ausgangsspalt bezeichnet wird. Zwischen diesen einzelnen Wechselwirkungsräumen befinden sich die Resonatoren 7, verbindend die Triftstrecken 17,18 und 19, und hinter dem Ausgangsspalt 16 noch die Triftstrecke 20, an die sich dann der Kollektor 6 des Mehrkammerklystrons anschließt. Die Triftstrecken 5,17 und 18 sind in bekannter Weise durch elektrostatische Fokussierungssysteme unterbrochen, die eine scharfe Bündelung des Elektronenstrahls zum nächsten Wechselwirkungsspalt hin bewirken. Die elektrostatischen Fokussiereinheiten liegen an einer gemeinsamen negativen Spannung 21, die gleich dem Kathodenpotential ist.About to vote, which are omitted here in this drawing for the sake of clarity. In the The interaction spaces 13,14,15 and 16 are arranged in the evacuated resonator parts last 16 is also referred to as the so-called exit gap. Between these individual interaction spaces are the resonators 7, connecting the drift sections 17, 18 and 19, and behind the exit gap 16 is the drift path 20, to which the collector 6 of the multi-chamber klystron then attaches connects. The drift paths 5, 17 and 18 are electrostatic in a known manner Interrupted focusing systems that provide a sharp focus of the electron beam to the next Cause interaction gap. The electrostatic focusing units are on a common negative voltage 21, which is equal to the cathode potential.
Zur besseren Führung des Elektronenstrahls 4 im Ausgangsspalt 16 sind nun nach der Erfindung etwa in Höhe der Triftstrecken 19 und der Triftstrecke 20 elektro- oder permanentmagnetische Systeme 22 undFor better guidance of the electron beam 4 in the exit slit 16 are now approximately according to the invention at the level of the drift sections 19 and the drift section 20, electromagnetic or permanent magnetic systems 22 and
23 angeordnet, die ein magnetisches Feld erzeugen, dessen Feldlinien in der Zeichnung strichpunktiert dargestellt sind. Das magnetische Feld ist im wesentlichen über den Ausgangsspalt 16 konzentriert, kann aber auch über den Wechselwirkungsspalt 15 streuen. Zur besseren Führung des magnetischen Feldes können die Resonatorflansche 11 und 12 der beiden letzten evakuierten Klystronresonatorteile 8, also die des Ausgangshohlraumresonators T und des in Elektronenstrahlrichtung vor diesem liegenden Resonators 7, aus Weicheisen bestehen. Auch die nicht evakuierten Resonatorteile 9 dieser letzten beiden Resonatoren können auf ihrem äußeren Umfang, wie bei23 arranged, which generate a magnetic field, the field lines are shown in dash-dotted lines in the drawing. The magnetic field is essentially concentrated over the exit gap 16, but can also scatter over the interaction gap 15. For better guidance of the magnetic field, the resonator flanges 11 and 12 of the last two evacuated klystron resonator parts 8, i.e. those of the output cavity resonator T and the resonator 7 in front of it in the electron beam direction, are made of soft iron. The non-evacuated resonator parts 9 of these last two resonators can on their outer circumference, as in
24 angedeutet, Weicheisenteile aufweisen. Um schließlich den Elektronenstrahl besser in die Kollektorkammer 25 einzuführen, trägt der Kollektor 6 auf seiner einen Stirnfläche einen aus Weicheisen bestehenden Abdeckring 26.24 indicated, have soft iron parts. In order to finally get the electron beam better into the collector chamber 25 to introduce, the collector 6 carries on its one end face a made of soft iron Cover ring 26.
An die Resonatorflansche 11 und 12 können sich in bekannter Weise am Laufraum Polschuhe anschließen, die eine besondere Führung des magnetischen Feldes ermöglichen.Pole shoes can be connected to the resonator flanges 11 and 12 in a known manner on the running space, which allow a special guidance of the magnetic field.
