Description

Das Bedürf>rvls nach h-trägheits!lose:nchaltniittelnt wie es bei einigen Fragen der Hochfr equ Lenztechnik auftritt, hat zur Entwicklung von sogenannten Elektroneustrahlschaltern geführt Deren Arbeitsweise beisteht im wesentlichen darin, das ein wohldefihiertrer Elektronenstrahl meist mit el.ektronenopÜschen Hilfsmitteln nach Art der Kathodenstrahlröhre konze=ntriert und durch elektrische oder magnetische Ableuvkmittel nacheinander auf verschiedene Fangelektroden gelenkt wird. Der Nach: teil dieser Schalter isst vor allem ihr hoher innerer Widerstand. Man hat mit Erfolg versucht, diesen durch sekundäirelektrisehe Verstärkung des Primärstrahlsi zu verringern., wobei jedoch der wohldefinierte Elektronenstrahl noch immer die Ausgangsquelle bLiebr. Dies hat den doppelten Nachteil, daZ ein; elekbronenopfsches Konzenbralionsisystem erforderlich ist und daß die meist punktförmig emittferentde Ernisetionsiqwel.le nur einen verhältnismäßig :geringen Ansgangs!strom liefert.The need> rvls for h-inertia! Loosely: connected as it is with some Issues of high-frequency bilge technology arise, has led to the development of so-called Electron beam switches, whose mode of operation essentially consists in that a well-defined electron beam mostly with electronic tools concentrated in the manner of the cathode ray tube and electric or magnetic Ableuvkmittel is successively directed to different collecting electrodes. The after: Part of these switches is mainly due to their high internal resistance. One has success tries to reduce this through secondary electrical amplification of the primary beam., however, the well-defined electron beam is still the output source. This has the double disadvantage that one; Elektronic Concentration System is necessary and that the mostly punctiform emittferentde Ernisetionsiqwel.le only a relative: low starting current supplies.

Diese Nachteile werden bei Anordbung en gemäß der vomliegenden Erfindung vermieden. Bei, dem mit Sekurvdäremiiss.io,n arbeitenden Elektronensehalter nach der Erfindung, bei dem die Elektronen durch ein den Entladungsraum durchsetzendes verähd2rliches Magnetfeld zu den Prall- und Auffangelektroden gelenkt werden, sind wenigstens zwei eine gemeinsame Pri!märlelektronenquieille@ aufweisende Reihenvervielfacherelektrodensysteme angeordnet, deren Auffangelektroden 'die Enden der Elektrodenreihen bilden, und deren Prallfläch:en längs einer Ebene entweder nebeneinandergereih!t oder Rücken an Rucken gelegt und den ihnen zugeordneten Beschleunigungselektroden gegeni'vbergesbellt sind, und das den Vervielfachersystemien gemeinsame Magnetfeld ist entweder alrs, steine Richtung =kehrendes Wechselquerfeld oder als um "ei!ne- senkrecht zu den Prellflächen gerichtete Achse sich. bewegendes konstantes Drehheld ausgebildet.These disadvantages become apparent with arrangements in accordance with the present invention avoided. In the case of the electron holder that works with securvdäremiiss.io, n of the invention, in which the electrons pass through a discharge space harmful magnetic field are directed to the impact and collecting electrodes at least two series multiplier electrode systems which have a common primary electron source arranged, whose collecting electrodes' form the ends of the electrode rows, and whose baffles are either lined up alongside one another or at the back along a plane put on the back and barked against the acceleration electrodes assigned to them are, and the magnetic field common to the multiplier systems is either alrs, stone direction = reversing alternating transverse field or as around "ei! ne- perpendicular to the Axis directed towards the bumpers. moving constant rotary hero formed.

Inder Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Mit K ist eine senkrecht zur Zeichenebene sich erstricakende,-direkt -oder indirekt beheizte gerade Kathode bezeichnet. A sind beiderseits emissionsfähige Prallelektroden, B sind Beschleunigungselektroden, a, a', b, b' Fangelektroden und E Elektronenbahnen, die nach dein Fangelektroden a und cl führen. Sie haben einen; spiegelbildlichen Verlauf, wenn das- im dargestellten Augenblick senkrecht zur Zeichenebene verlaufende Magnetfeld eine Drehtang um i8d°voillzoigen hat. In diesem Augenblick fließt er Strom zu, den Fangelektroden b, b'. An Stelle eines Drehfelds kann auch ein magnetisches, sehie Richtung umkehrendes Wechselfeld treten. Die- Anordnung und Befestigung der Prall- und Fangelektroden kann in der bei Vervielfachern bekannten Art erfolgen.In the drawing, an embodiment of the invention is shown. A straight cathode which is drawn, directly or indirectly heated perpendicular to the plane of the drawing is designated by K. A are emissive impact electrodes on both sides, B are acceleration electrodes, a, a ', b, b' target electrodes and E electron paths that lead to your target electrodes a and cl. They have one; mirror-image course, if the magnetic field running perpendicular to the plane of the drawing at the moment shown has a rotation through i8d ° full. At this moment the current flows to the target electrodes b, b '. Instead of a rotating field, a magnetic alternating field that reverses direction can also be used. The arrangement and attachment of the impact and collecting electrodes can be carried out in the manner known from multipliers.
