Description

Mehrkammertriftröhren haben den Nachteil, daß bei einer Frequenzänderüng beide Kammern, d. h: sowohl der Steuerschwingkreis wie auch der Auskoppelschwingkreis; beeinflußt werden müssen.Multi-chamber drift tubes have the disadvantage that with a frequency change both chambers, d. h: both the control oscillating circuit and the decoupling oscillating circuit; must be influenced.

Die Verstimmung wurde bisher meist dadurch bewirkt, daß die Schwingkreise mechanisch deformiert werden. Die dabei verwandten Konstruktionen ergaben Schwierigkeiten in der Abführung der entstehenden Verlustwärmen und auch in der Reproduzierbarkeit der Einstellung. Außerdem müssen bei der Frequenzänderung stets zwei Abstimmgriffe im Gleichlauf bewegt werden. Die Erfindung schlägt daher vor, die Abstimmung durch Eintauchen eines Keramik- öder Metallkörpers in beide Kammern zu ändern.The detuning was mostly caused by the fact that the oscillating circuits be mechanically deformed. The constructions used in this process gave rise to difficulties in the dissipation of the resulting heat loss and also in the reproducibility the attitude. In addition, two tuning handles must always be used when changing the frequency be moved in synchronism. The invention therefore proposes the vote Immersing a ceramic or metal body to change both chambers.

In den Abb. i und 2 sind beispielsweise Ausführungsformen der Erfindung dargestellt.Examples of embodiments of the invention are shown in Figs shown.

In einem metallischen Röhrenkolben i, der mittels eines Flansches 2, der Kupferschnei.denglasverbindung 3 und dem Glasteller q: vakuumdicht ahgeschlossen ist, ist das Schwingkreissystem 5 eingelötet. Es besteht aus einem zylindrischen Resonator 6 mit den beiden Deckflächen 7 und B. Der so entstehende dosenförmige Resonator besitzt in der Mitte der Höhe eine durchbrochene Metallplätte g, welche den Resonator in eine obere und eine untere Hälfte teilt; welche die Auskoppel- und Steuerkammer bilden. Die Durchbrechungen von der oberen zur unteren Kammer dienen zur Kopplung der beiden Kreise, wodurch die Rückkopplung und damit Selbsterregung der Anordnung eintritt. Der Resonator wird in seiner Längsachse von der Kathode io aus mit -einem Elektronenstrahl in seiner Achsrichtung durchschossen und angeregt.In a metallic tubular piston i, which by means of a flange 2, the copper cutting glass connection 3 and the glass plate q: closed in a vacuum-tight manner is, the resonant circuit system 5 is soldered. It consists of a cylindrical Resonator 6 with the two top surfaces 7 and B. The resulting can-shaped In the middle of the height, the resonator has a perforated metal plate g, which divides the resonator into an upper and a lower half; which the decoupling and form the control chamber. The openings from the upper to the lower chamber are used to couple the two circuits, creating the feedback and thus self-excitation the order occurs. The longitudinal axis of the resonator is connected to the cathode io shot through with an electron beam in its axial direction and excited.

Zur Abstimmung- beider Kammern wird nun gemäß der Erfindung ein Keramik- oder Metallstab i i in der Ebene der Trennwand senkrecht zur Achsrichtung des Elektronenstrahles in den Resonator eingetaucht, wodurch beide Kammern im gleichen Mäße verstimmt werden. Die Frequenzabstimmung kann so von außen mit Hilfe des metallischen Federkörpers 12 durch mehr öder weniger tiefes Einschieben in den Resonator vorgenommen werden. Verwendet man als eintauchenden Keramikstab einen solchen mit hoher Dielektrizitätskonstante, so kann damit eine Verstimmung des Kreises um ± 151/o erzielt werden.To coordinate both chambers, a ceramic is now according to the invention or metal rod i i in the plane of the partition wall perpendicular to the axial direction of the electron beam immersed in the resonator, whereby both chambers are detuned to the same extent. The frequency tuning can be done from the outside with the help of the metallic spring body 12 can be made by inserting it more or less deeply into the resonator. If a ceramic rod with a high dielectric constant is used as the immersed ceramic rod, in this way a detuning of the circle by ± 151 / o can be achieved.

Wenn die beiden Kammern relativ stark miteinander gekoppelt sind; so besteht auch die Möglichkeit, durch Eintauchen eines Stiftes parallel zur Richtung des Elektronenstrahles; wie in Abb. 2 gezeigt, zu verstimmen. Der Stab 1q. durchsetzt zunächst die obere Kammer und verstimmt dieselbe: Dabei wird über die feste Kopplung die untere Kammer in ihrer Wellenlänge mitgezogen. Bei weiterem Eintauchen des Stiftes durchsetzt er auch die untere Kammer und erniedrigt dadurch die- Frequenz. Auch in dieser Anordnung kommt man mit einem Abstimmstab aus.When the two chambers are relatively strongly coupled to one another; so there is also the possibility of dipping a pen parallel to the direction of the electron beam; to detune as shown in Fig. 2. The rod 1q. interspersed first the upper chamber and detuned it: This is about the fixed coupling the lower chamber dragged along in its wavelength. If the pen is further immersed it also penetrates the lower chamber and thereby lowers the frequency. Even in this arrangement one gets by with a tuning rod.
