Abstract

The invention relates to an X-ray image intensifier (1) which is used in an X-ray device in order to produce a visible image from an X-ray shadowgraph. In such X-ray image intensifiers (1), the vacuum-tight bushings (13, 14) of the contact pins (11, 12) for the voltage supply to the electrodes (8, 9), the bearings of the electrodes and the insulation of the electrodes (8, 9) form problems with respect to one another, since they must be stable in a vacuum and must not cause the vacuum to deteriorate by the emission of atoms. In an X-ray image intensifier according to the invention, a first electrically conductive part (2, 8, 11) is connected via bonding to a second electrically conductive part (3, 9, 12) by the bonding being effected by glass or enamel. This bonding is mechanically strong and can be produced with a low cost outlay and has good dielectric strength. In particular, these bonds are vacuum-tight and no atoms which cause the vacuum to deteriorate are emitted from the bonding. <IMAGE>

Description

Die Erfindung betrifft einen Röntgenbildverstärker, der beispielsweise bei Röntgeneinrichtungen eingesetzt wird, um aus einem Röntgenschattenbild ein sichtbares Bild zu erzeugen. Solche Röntgenbildverstärker besitzen ein annähernd zylinderförmiges Vakuumgefäß, an dessen einer Stirnseite ein Eingangsleuchtschirm und an dessen anderer Stirnseite ein Ausgangsleuchtschirm angeordnet ist. Im Inneren des Vakuumgefäßes sind Elektroden vorgesehen, die über Halterungselemente im Vakuumgefäß gehalten sind. Zum Fokussieren der beim Auftreffen von Röntgenstrahlung auf dem Eingangsleuchtschirm erzeugten Elektronen auf den Ausgangsleuchtschirm wird eine Spannung an die Elektroden angelegt, die diesen über Kontaktstifte zuführbar ist, die vakuumdicht durch das Vakuumgefäß geführt sind. Es ist bekannt, die Elektroden über ein Isoliermaterial miteinander zu verbinden, so daß sich eine stabile Elektrodenanordnung im Vakuumgefäß ergibt.The invention relates to an X-ray image intensifier, which is used, for example, in X-ray devices in order to generate a visible image from an X-ray silhouette. Such X-ray image intensifiers have an approximately cylindrical vacuum vessel, on the one end of which there is an input fluorescent screen and on the other end of which an output fluorescent screen is arranged. Electrodes are provided in the interior of the vacuum vessel and are held in the vacuum vessel by means of holding elements. In order to focus the electrons generated when X-rays strike the input fluorescent screen onto the output fluorescent screen, a voltage is applied to the electrodes which can be supplied to them via contact pins which are guided through the vacuum vessel in a vacuum-tight manner. It is known to connect the electrodes to one another via an insulating material, so that there is a stable electrode arrangement in the vacuum vessel.

Die Durchführung der Kontaktstifte durch das Vakuumgefäß sowie die Halterung der Elektroden und die Befestigung der Elektroden untereinander verursacht insofern Probleme, da aus dem zur Abdichtung bzw. Befestigung dienenden Material Atome austreten, die das Vakuum verschlechtern.The implementation of the contact pins through the vacuum vessel and the mounting of the electrodes and the fastening of the electrodes to one another causes problems in that atoms come out of the material used for sealing or fastening, which deteriorate the vacuum.

Aufgabe der Erfindung ist es daher, einen Röntgenbildverstärker der eingangs genannten Art so auszubilden, daß eine vakuumdichte Durchführung der Kontaktstifte durch das Vakuumgefäß erhalten wird und daß das Vakuum auch über eine lange Betriebsdauer des Röntgenbildverstärkers nur unwesentlich verschlechtert wird.The object of the invention is therefore to design an X-ray image intensifier of the type mentioned at the outset in such a way that a vacuum-tight passage of the contact pins is obtained through the vacuum vessel and that the vacuum is only insignificantly deteriorated even over a long operating time of the X-ray image intensifier.

Die Aufgabe wird erfindungsgemäß durch einen Röntgenbildverstärker gelöst, bei dem ein erstes elektrisch leitendes Teil über eine Verklebung mit einem zweiten elektrisch leitenden Teil dadurch verbunden ist, daß die Verklebung durch Glas erfolgt.The object is achieved according to the invention by an X-ray image intensifier in which a first electrically conductive part is connected to a second electrically conductive part by gluing in that the gluing takes place through glass.

Die Aufgabe wird zudem durch einen Röntgenbildverstärker gelöst, bei dem ein erstes elektrisch leitendes Teil über eine Verklebung mit einem zweiten elektrisch leitenden Teil dadurch verbunden ist, daß die Verklebung durch Emaille erfolgt.The object is also achieved by an X-ray image intensifier, in which a first electrically conductive part is connected to a second electrically conductive part by means of an adhesive bond being made by enamel.

Vorteil der Erfindung ist, daß somit eine mechanisch feste, mit geringem Kostenaufwand herstellbare und spannungsfeste Verbindung hergestellt wird. Insbesondere wird hierdurch eine Verbindung hergestellt, die das Vakuum im Inneren des Röntgenbildverstärkers nicht durch aus der Klebeverbindung ausdampfende Atome verschlechtert.The advantage of the invention is that a mechanically strong, stress-resistant connection can be produced at low cost. In particular, this creates a connection that does not degrade the vacuum inside the X-ray image intensifier due to atoms evaporating from the adhesive connection.

In der Figur 1 ist ein Ausschnitt eines Röntgenbildverstärkers 1 gezeigt. Zur Orientierung würde sich links der Eingangs- und rechts der Ausgangsleuchtschirm des Röntgenbildverstärkers 1 anschließen. Das Gehäuse des Röntgenbildverstärkers 1 wird, wie in dieser Darstellung gezeigt, von einem ersten und einem zweiten elektrisch leitenden Teil 2, 3 gebildet, welche als Zylinder aus einem Blechstreifen geformt sind. Im Bereich 4 ist ein Ende 5 des ersten Gehäuseteiles 2 über eine erfindungsgemäße Glas- oder Emailleverklebung 6 mit dem einen Ende 7 des zweiten Gehäuseteiles 3 verbunden.A section of an X-ray image intensifier 1 is shown in FIG. The input and Connect the exit fluorescent screen of the X-ray image intensifier 1 to the right. As shown in this illustration, the housing of the X-ray image intensifier 1 is formed by a first and a second electrically conductive part 2, 3, which are shaped as cylinders from a sheet metal strip. In area 4, one end 5 of the first housing part 2 is connected to one end 7 of the second housing part 3 via a glass or enamel adhesive 6 according to the invention.

Im Röntgenbildverstärker 1 ist eine erste und eine zweite zylinderförmige Elektrode 8, 9 angeordnet, die sich in einem Bereich 10 überlappen und über eine Verklebung aus Glas oder Emaille miteinander verbunden sind.A first and a second cylindrical electrode 8, 9 are arranged in the X-ray image intensifier 1, which overlap in an area 10 and are connected to one another by means of an adhesive made of glass or enamel.

Zur elektrischen Kontaktierung der Elektroden 8, 9 ist ein elektrisch leitender Stift 11 bzw. 12 durch eine vorzugsweise konische Durchführung 13 bzw. 14 in den Gehäuseteilen 2 bzw 3 geführt. Der Stift 11 bzw. 12 ist über eine Verklebung 15 bzw. 16 aus Glas oder Emaille mit dem ersten bzw. zweiten Gehäuseteil 2, 3 verbunden. Diese Stifte 11, 12 können zudem zur Halterung der Elektroden 8, 9 im Röntgenbildverstärker 1 dienen. Hierzu können auch weitere Stifte 17, 18 vorgesehen sein, die über eine Verklebung 19, 20 aus Glas oder Emaille mit den Elektroden 8, 9 und den Gehäuseteilen 2, 3 verbunden sind.For the electrical contacting of the electrodes 8, 9, an electrically conductive pin 11 or 12 is guided through a preferably conical bushing 13 or 14 in the housing parts 2 or 3. The pin 11 or 12 is connected to the first or second housing part 2, 3 by means of an adhesive 15 or 16 made of glass or enamel. These pins 11, 12 can also serve to hold the electrodes 8, 9 in the X-ray image intensifier 1. For this purpose, further pins 17, 18 can also be provided, which are connected to the electrodes 8, 9 and the housing parts 2, 3 via an adhesive 19, 20 made of glass or enamel.

Zur Verklebung der elektrisch leitenden Teile, hier also der Gehäuseteile 2, 3, der Elektroden 8, 9 sowie der Stifte 11, 12; 17, 18 mit den Gehäuseteilen 2, 3 kann auf diesen eine Beschichtung aus Emaille oder Glas vorgesehen sein, die beispielsweise durch Auftrag von Emaille- oder Glaspulver auf die Teile und durch anschließende, den Auftrag schmelzende Erwärmung erhalten wird. Nachdem die elektrisch leitenden Teile zusammengefügt sind, erfolgt die Verklebung der Teile durch Schmelzen der Beschichtung bei Wärmezufuhr und anschließender Abkühlung.For gluing the electrically conductive parts, here the housing parts 2, 3, the electrodes 8, 9 and the pins 11, 12; 17, 18 with the housing parts 2, 3, a coating of enamel or glass can be provided thereon, which is obtained, for example, by applying enamel or glass powder to the parts and by subsequent heating that melts the application. After the electrically conductive parts have been joined, the parts are glued by melting the coating when heat is applied and then cooling.

Zur Verbindung können selbstverständlich auch Glas- oder Emailleformteile eingesetzt werden, die zwischen den zu verbindenden Teilen angeordnet sind. Durch Wärmezufuhr schmelzen diese Formteile auf die zu verbindenden Teile auf und bei anschließender Abkühlung werden die Teile miteinander verklebt.Of course, glass or enamel molded parts which are arranged between the parts to be connected can also be used for the connection. By applying heat, these molded parts melt onto the parts to be connected and when they cool down, the parts are glued together.

In der Figur 2 soll eine Verklebung durch ein Formteil erläutert werden. Ein elektrisch leitendes Gehäuseteil 21 eines Röntgenbildverstärkers ist gezeigt, in welches eine zylindrische Durchführung 22 eingebracht ist, durch die ein elektrisch leitender Stift 23 führt. Der Stift 23 weist einen Rand 24 auf, der sich über ein beispielsweise ringförmiges Formstück 25 aus Glas oder Emaille auf dem elektrisch leitenden Teil 21 abstützt. Durch Wärmezuführung schmilzt das ringförmige Formstück 25 und verbindet somit den Stift 23 mit dem elektrisch leitenden Teil 21 durch Aufschmelzen. Die Verklebung des Stiftes 23 mit dem elektrisch leitenden Teil 21 erfolgt bei Abkühlung.In Figure 2, an adhesive bond is to be explained by a molded part. An electrically conductive housing part 21 of an X-ray image intensifier is shown, into which a cylindrical bushing 22 is inserted, through which an electrically conductive pin 23 leads. The pin 23 has an edge 24 which is supported on the electrically conductive part 21 via an, for example, annular shaped piece 25 made of glass or enamel. By applying heat, the annular shaped piece 25 melts and thus connects the pin 23 to the electrically conductive part 21 by melting. The pin 23 is glued to the electrically conductive part 21 when it cools down.

In den Figuren 3 bis 5 ist ein Ausschnitt eines bevorzugten Röntgenbildverstärkers gezeigt, bei dem ein elektrisch leiten-des Teil als Gehäuseteil des Röntgenbildverstärkers mit dem Bezugszeichen 26 gekennzeichnet ist. Im Bereich 27 nimmt das elektrisch leitende Teil 26 den Kopf eines nietförmigen Kontaktstiftes 28 auf, wobei der Schaft des nietförmigen Kontaktstiftes 28 durch eine Durchführung 29 im elektrisch leitenden Teil 26 geführt ist. Auf dem elektrisch leitenden Teil 26 ist eine Beschichtung 30 aus Glas oder Emaille aufgebracht, die zur Isolierung des nietförmigen Konaktstiftes 28 gegen das elektrisch leitende Teil 26 dient. Auf dieser Beschichtung 30 kann ein elektrisch leitender Belag 31 aufgedampft sein, dem über den Kontaktstift 28 eine Spannung zuführbar ist. Insbesondere kann der elektrisch leitende Belag 31 eine Elektrode des Röntgenbildverstärkers bilden. Hierbei kann dann im Unterschied zum Röntgenbildverstärker nach Figur 1 vorteilhaft auf Halterungen für die Elektroden verzichtet werden.FIGS. 3 to 5 show a section of a preferred X-ray image intensifier, in which an electrically conductive part is identified as reference number 26 as the housing part of the X-ray image intensifier. In region 27, the electrically conductive part 26 receives the head of a rivet-shaped contact pin 28, the shaft of the rivet-shaped contact pin 28 being guided through a passage 29 in the electrically conductive part 26. A coating 30 made of glass or enamel is applied to the electrically conductive part 26 and serves to isolate the rivet-shaped contact pin 28 from the electrically conductive part 26. On this coating 30 For example, an electrically conductive coating 31 can be vapor-deposited, to which a voltage can be supplied via the contact pin 28. In particular, the electrically conductive coating 31 can form an electrode of the X-ray image intensifier. In contrast to the X-ray image intensifier according to FIG. 1, holders for the electrodes can then advantageously be dispensed with.

Solche erfindungsgemäßen Verklebungen können preiswert hergestellt werden, sie weisen eine hohe mechanische Festigkeit auf und haben eine hohe Spannungsfestigkeit. Zudem sind diese Verklebungen vakuumdicht und haben den erheblichen Vorteil, daß sie im Vakuum stabil sind und somit das Vakuum nicht verschlechtern.Such bonds according to the invention can be produced inexpensively, they have a high mechanical strength and a high dielectric strength. In addition, these bonds are vacuum-tight and have the considerable advantage that they are stable in a vacuum and thus do not deteriorate the vacuum.
