Boggia et al., Published in Nuclear Instruments and Methods in Physics Research, A 382 (1996), pages 73-77 , such a particle accelerator is known.

Die Aufgabe der vorliegenden Erfindung besteht darin, einen Teilchenbeschleuniger der eingangs genannten Art derart weiter zu entwickeln, dass er einfach und kompakt aufgebaut ist und mit einer hohen Spannung betreibbar ist.The object of the present invention is to develop a particle accelerator of the type mentioned in such a way that it is simple and compact and can be operated with a high voltage.

Die Aufgabe wird durch einen Teilchenbeschleuniger mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausgestaltungen des erfindungsgemäßen Teilchenbeschleunigers sind Gegenstand der abhängigen Ansprüche 2 bis 4.The object is achieved by a particle accelerator having the features of claim 1. Advantageous embodiments of the particle accelerator according to the invention are the subject of the dependent claims 2 to 4.

Erfindungsgemäß ist bei einem Teilchenbeschleuniger der eingangs genannten Art vorgesehen, dass - zusätzlich zur Anordnung der mindestens einen Elektrodenstruktur und des Spannungsvervielfachers innerhalb der evakuierten Beschleunigerzelle - die Wechselspannung zur Speisung des Spannungsvervielfachers innerhalb der Beschleunigerzelle generiert wird.According to the invention, in a particle accelerator of the type mentioned in the introduction, it is provided that, in addition to the arrangement of the at least one electrode structure and the voltage multiplier within the evacuated accelerator cell, the AC voltage for feeding the voltage multiplier within the accelerator cell is generated.

Der Spannungsvervielfacher zur Spannungsvervielfachung der Wechselspannung weist eine Anzahl von Kondensatorstufen auf, die über Dioden miteinander verbunden sind. Weiterhin weist auch die Elektrodenstruktur eine Anzahl von Kondensatorflächen auf. Dabei sind die Kondensatorflächen der Elektrodenstruktur mit den Kondensatorstufen des Spannungsvervielfachers identisch. Dadurch ergibt sich eine besonders kompakte Bauweise des Teilchenbeschleunigers.The voltage multiplier for voltage multiplication of the AC voltage has a number of capacitor stages, which are connected to each other via diodes.

FIG. 2
a voltage multiplier,
FIG. 3
a detail of the particle accelerator in a first embodiment and
FIG. 4
a detail of the particle accelerator in a second embodiment.

Gemäß FIG 1 weist ein Teilchenbeschleuniger eine Beschleunigungszelle 1 auf. Die Beschleunigungszelle 1 ist evakuiert. Die Beschleunigungszelle 1 dient dazu, eine Umgebung zu schaffen, in der ein Teilchenstrahl 2 "leben" kann, also nicht sofort durch Ionisation von Luftmolekülen oder anderweitige Interaktion mit den Luftmolekülen seine kinetische Energie verliert.According to FIG. 1 a particle accelerator has an acceleration cell 1. The acceleration cell 1 is evacuated. The acceleration cell 1 serves to create an environment in which a particle beam 2 can "live", ie not immediately loses its kinetic energy by ionization of air molecules or other interaction with the air molecules.

Der Teilchenbeschleuniger weist weiterhin mindestens eine Elektrodenstruktur 3 auf. An der Elektrodenstruktur 3 liegt im Betrieb des Teilchenbeschleunigers eine Hochspannung an. Dies ist in FIG 1 durch das für elektrische Spannungen übliche Blitzzeichen angedeutet. Die Hochspannung wirkt auf den Teilchenstrahl 2. Beispielsweise kann die Elektrodenstruktur 3 als Beschleunigungselektrode, als Bremselektrode, als Fokussierungselektrode, als Umlenkelektrode oder anders ausgebildet sein. Die Hochspannung wird im Betrieb des Teilchenbeschleunigers von einer entsprechenden Stromversorgungseinrichtung 4 generiert. Die Stromversorgungseinrichtung 4 ist detaillierter in FIG 2 dargestellt.The particle accelerator furthermore has at least one electrode structure 3. A high voltage is applied to the electrode structure 3 during operation of the particle accelerator. This is in FIG. 1 indicated by the standard for electrical voltages lightning. The high voltage acts on the particle beam 2. For example, the electrode structure 3 as an acceleration electrode, as a brake electrode, as a focusing electrode, as a deflection electrode or otherwise. The high voltage is generated by a corresponding power supply device 4 during operation of the particle accelerator. The power supply device 4 is more detailed in FIG FIG. 2 shown.

Gemäß FIG 2 ist die Stromversorgungseinrichtung 4 als Spannungsvervielfacher ausgebildet, der mit Wechselspannung U gespeist wird. Beispielsweise kann die Stromversorgungseinrichtung 4 zur Spannungsvervielfachung eine geeignete Anzahl von Kondensatorstufen 5 aufweisen, die über Dioden 6 miteinander verbunden sind. Derartige Spannungsvervielfacher können beispielsweise als so genannte Greinacherschaltung oder auch Greinacherkaskade ausgebildet sein und bewirken, dass am Ausgang des Spannungsvervielfachers eine Gleichspannung mit einer Amplitude abgreifbar ist, welche ein Vielfaches der Amplitude der Wechselspannung U beträgt.According to FIG. 2 the power supply device 4 is designed as a voltage multiplier, which is fed with AC voltage U. For example, the power supply device 4 for voltage multiplication may have a suitable number of capacitor stages 5, which are connected to one another via diodes 6. Such voltage multipliers can for example be designed as a so-called Greinacher circuit or Greinacherkaskade and cause the output of the voltage multiplier a DC voltage with an amplitude can be tapped, which is a multiple of the amplitude of the AC voltage U.

Erfindungsgemäß ist gemäß FIG 1 weiterhin vorgesehen, dass die Elektrodenstruktur 3 und die Stromversorgungseinrichtung 4 innerhalb der evakuierten Beschleunigerzelle 1 angeordnet sind. Dadurch ergibt sich ein einfacher und kompakter Aufbau des Teilchenbeschleunigers.According to the invention is according to FIG. 1 Furthermore, provision is made for the electrode structure 3 and the power supply device 4 to be arranged within the evacuated accelerator cell 1. This results in a simple and compact construction of the particle accelerator.

Die Wechselspannung U kann innerhalb der Beschleunigerzelle 1 generiert werden. Beispielsweise ist es möglich, innerhalb der Beschleunigerzelle 1 eine Sekundärwicklung 10 eines Transformators 8 anzuordnen, der über eine Primärwicklung 9 des Transformators 8 gespeist wird. Die Primärwicklung 9 des Transformators 8 kann in diesem Fall außerhalb der Beschleunigerzelle 1 angeordnet sein (FIG 4). Gemäß FIG 1 wird die Wechselspannung U der Stromversorgungseinrichtung 4 jedoch von außerhalb der Beschleunigerzelle 1 zugeführt.The alternating voltage U can be generated within the accelerator cell 1. For example, it is possible to arrange within the accelerator cell 1 a secondary winding 10 of a transformer 8, which is fed via a primary winding 9 of the transformer 8. The primary winding 9 of the transformer 8 may in this case be arranged outside the accelerator cell 1 ( FIG. 4 ). According to FIG. 1 However, the AC voltage U of the power supply device 4 is supplied from outside the accelerator cell 1.

In vielen Fällen weist die Elektrodenstruktur 3 eine Anzahl von Kondensatorflächen 7 auf. Die Kondensatorflächen 7 können bespielsweise, wie in FIG 3 dargestellt, in Form von konzentrischen Ringen angeordnet sein, wobei der Teilchenstrahl 2 entlang der Symmetrieachse der Ringe 7 beschleunigbar ist. Hier sind jedoch auch andere Ausgestaltungen möglich. Falls die Anzahl von Kondensatorflächen 7 vorhanden ist, können die Kondensatorflächen 7 der Elektrodenstruktur 3 mit den Kondensatorstufen 5 des Spannungsvervielfachers 4 identisch sein.In many cases, the electrode structure 3 has a number of capacitor surfaces 7. The capacitor surfaces 7 can bespielsweise, as in FIG. 3 shown in the form of concentric Be arranged rings, wherein the particle beam 2 along the axis of symmetry of the rings 7 can be accelerated. Here, however, other configurations are possible. If the number of capacitor surfaces 7 is present, the capacitor surfaces 7 of the electrode structure 3 may be identical to the capacitor stages 5 of the voltage multiplier 4.

Wie ebenfalls der FIG 3 zu entnehmen ist, sind die Dioden 6 der Stromversorgungseinrichtung 4 zur Spannungsvervielfachung ebenfalls in die Beschleunigerzelle 1 integriert und verbinden wie im Zusammenhang mit der FIG 2 beschrieben die Kondensatorflächen 7 der Elektrodenstruktur 3 miteinander, um sie auf von außen nach innen ansteigende Potentialstufen zu bringen, so dass letztlich die innere Elektrode auf dem höchsten Potential liegt.Like the same FIG. 3 can be seen, the diodes 6 of the power supply device 4 for voltage multiplication are also integrated into the accelerator cell 1 and connect as in connection with the FIG. 2 described the capacitor surfaces 7 of the electrode structure 3 together to bring them to rise from outside to inside potential levels, so that ultimately the inner electrode is at the highest potential.

Die vorliegende Erfindung weist viele Vorteile auf. Insbesondere ist der erfindungsgemäße Teilchenbeschleuniger kompakt realisierbar und arbeitet zuverlässig. Die mögliche Hochspannung ist gegenüber einem konventionellen Teilchenbeschleuniger deutlich erhöht. Weiterhin ist es möglich, die Anzahl an benötigten Bauteilen zu reduzieren.The present invention has many advantages. In particular, the particle accelerator according to the invention is compact and works reliably. The potential high voltage is significantly increased compared to a conventional particle accelerator. Furthermore, it is possible to reduce the number of components required.

Die obige Beschreibung dient ausschließlich der Erläuterung der vorliegenden Erfindung. Der Schutzumfang der vorliegenden Erfindung soll hingegen ausschließlich durch die beigefügten Ansprüche bestimmt sein.The above description is only for explanation of the present invention. The scope of the present invention, however, is intended to be determined solely by the appended claims.

Grundsätzlich kann der Teilchenbeschleuniger mit nur einer einzigen derartigen Beschleunigerzelle betrieben werden. Die einzelne Beschleunigerzelle stellt also für sich schon einen Teilchenbeschleuniger dar.In principle, the particle accelerator can be operated with only a single such accelerator cell. The single accelerator cell thus already represents a particle accelerator.
