Description

Die Erfindung betrifft einen Röntgenbildverstärker mit einem Eingangsschirm, der mittels einer Klemmverbindung mit einem Gehäuse vakuumdicht verbunden ist. The invention relates to an X-ray image intensifier having an input screen which is vacuum-tight manner by means of a clamping connection with a housing. Ein solcher Röntgenbild verstärker ist aus der DE 25 13 894 A1 bekannt. Such X-ray image-amplifier from DE 25 13 894 A1. Die Klemm verbindung wird dort mittels eines zusätzlich erforderlichen Rings erzeugt. The clamping connection is created there by means of a separate ring.

Bei bekannten Vakuum-Röhren, wie z. In prior art vacuum tube, such. B. Röntgenbildverstärkern, besteht der die Röntgen- oder Gammastrahlen durchlassende Eingangsschirm aus schwach absorbierenden Materialien, wie z. B. X-ray image intensifiers is the x-ray or gamma-rays transmitting the input screen from a weakly-absorbing materials, such. B. Beryllium, Titan oder Aluminium. B. beryllium, titanium or aluminum. Das Gehäuse des Rönt genbildverstärkers besteht aus Schwermetallen, wie Stahl oder Edelstahl. The housing of the Rönt genbildverstärkers consists of heavy metals, such as steel or stainless steel. Zum vakuumdichten Verbinden des Eingangsschirmes mit dem Gehäuse ist es bekannt, zumindest die zu verbindenden Flächen galvanisch zu vernickeln bzw. zu versilbern und dann eine Diffusionsschweißung durchzuführen. For vacuum-tight connection of the input screen to the housing, it is known to nickel, at least the surfaces to be connected electrically or to silver and then perform diffusion bonding. Bekannterweise kann eine Preßverschweißung oder eine Reibschweißung, eine Keil reibschweißung oder bei besonders dünnen Folien, wie Titanfo lien, eine Direktverschweißung eine entsprechende Verbindung herbeiführen. Known manner, a Preßverschweißung or friction welding, friction welding, a wedge or cause a corresponding compound in particularly thin films, such as Titanfo lien, a Direktverschweißung. Ein derartiger Röntgenbildverstärker ist aus der DE 26 19 293 B2 bekannt. Such an X-ray image intensifier is known from DE 26 19 293 B2.

Aufgabe der Erfindung ist es, eine vakuumdichte Verbindung zwischen einem Eingangsschirm eines Röntgenbildverstärkers und dessen Gehäuse auf kostengünstige Weise herzustellen. The object of the invention is to provide a vacuum-tight connection between an input screen of an X-ray image intensifier and its housing in an inexpensive manner.

Die Aufgabe wird erfindungsgemäß durch den Gegenstand des Patentanspruchs 1 gelöst. The object is solved by the subject of claim 1. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen angegeben. Advantageous embodiments are disclosed in the dependent claims.

Zur Erläuterung der Erfindung wird nachfolgend auf die Fig. 1 bis 4 verwiesen. To explain the invention reference is made below to FIGS. 1 to 4.

Fig. 1-4 zeigen die Verfahrensschritte zum Herbeiführen einer Klemmverbindung zwischen dem Rand des Ein gangsschirmes und dem Rand des Gehäuses. Fig. 1-4 show the process steps for causing a clamping connection between the edge of a screen transition and the edge of the housing.

In den Figuren sind gleiche Elemente mit den gleichen Bezugs zeichen versehen. In the figures the same elements have the same reference signs are provided. Mit dem Bezugszeichen 1 ist ein Gehäuse und mit dem Bezugszeichen 2 ein Eingangsschirm eines Röntgenbild verstärkers gekennzeichnet. By reference numeral 1 is a housing and the reference numeral 2, an input screen of an X-ray image intensifier is characterized. Aus der Fig. 1 ist ersichtlich, daß ein Rand 3 des Gehäuses 1 Z-förmig abgewinkelt ist. From Fig. 1 it is apparent that an edge 3 of the housing 1 angled Z-shaped. Auf den in den Figuren horizontal ausgerichteten Teil des Randes 3 ist ein Rand 4 des Eingangsschirmes 2 gelegt. On the horizontally aligned in the figures part of the rim 3 an edge 4 of the entrance screen 2 is placed. Zur Herstel lung einer erfindungsgemäßen Klemmverbindung wird der in der Fig. 1 vertikal ausgerichtete Endrandteil um den Rand 4 des Eingangsschirmes 2 gebogen, so daß der Rand 4 in einer Klemm verbindung gehalten ist ( Fig. 2). For the manufacture lung of a clamping connection according to the invention the vertically oriented in Fig. 1 end edge portion is bent around the edge 4 of the entrance screen 2, so that the rim is held in a clamping connection 4 (Fig. 2).

In der Fig. 3 ist gezeigt, daß eine Klemmvorrichtung 5 an dem umgebörtelten Rand 3 des Gehäuses 1 angreift und daß zum Her beiführen einer Diffusionshaftung eine Kraft P auf diesen einwirkt. In FIG. 3, it is shown that a clamping device 5 engages the umgebörtelten edge 3 of the housing 1 and that for Her a diffusion adhesion beiführen a force P acting on these. Das Pressen der Ränder 3 , 4 erfolgt für ca. 30 Minu ten, bei einer Temperatur von ca. 500°C, so daß das Aluminium zu fließen beginnt und durch das Aufreißen der Aluminiumoxid haut eine Diffusionshaftung zwischen dem Aluminium und dem Stahl herbeigeführt wird. The pressing of the edges 3, 4 is carried out for about 30 Minu th, at a temperature of about 500 ° C, so that the aluminum begins to flow through the tearing of the aluminum skin, a diffusion bond between the aluminum and the steel is brought about.

Versieht man, wie in der Fig. 4 gezeigt, ein Teilstück 6 der Preßvorrichtung 5 mit einem Keilprofil 7 , so können Oberflä chenfehler der Ränder 3 und 4 , wie z. You know, as shown in FIG. 4, a section 6 of the press device 5 with a wedge profile 7, so Oberflä can chenfehler the edges 3 and 4 as z. B. Kratzer und Drehril len beim Pressen egalisiert werden. As scratches and Drehril len be leveled during pressing.

Gemäß einer vorteilhaften Variante sind die einander zuge wandten Kontaktflächen der Ränder 3 und 4 mit einer Dichtmas se, beispielsweise einem Kleber versehen, der während einer nachfolgenden Vakuumausheizung aushärtet. According to an advantageous variant, the mutually facing contact surfaces of the edges are se 3 and 4 with a Dichtmas, provided, for example, an adhesive which hardens during a subsequent Vakuumausheizung. Geeignete Kleber sind z. Suitable adhesives are, for. B.: EPO.Tek 314 , Shore D80, Nr. 7030, Nr. 952, Nr. 954, Durapot 863 , die von der Fa. Polytec GmbH, Waldbornn, herge stellt werden.
