Description

Bei der Untersuchung mittels Röntgenstrahlen, insbesondere bei der Materialuntersuchung, werden bekanntlich verschieden große Brennflecke benutzt.When examining with X-rays, especially when Material investigation, it is known that focal spots of different sizes are used.

Eine besonders vorteilhafte Ausführungsform einer Drehanodenröntgenröhre, die es gestattet, zwei oder mehrere verschieden große Brennflecke mit verschiedener Nutzstrahlenrichtung in Betrieb zu nehmen, ist in der Abb. i im Längsschnitt durch die Röntgenröhrenelektroden und in der Abb. 2 in der Draufsicht auf die Anode schematisch wiedergegeben.A particularly advantageous embodiment of a rotating anode X-ray tube, which allows two or more different sized focal points with different To put the useful beam direction into operation is shown in Fig. I in the longitudinal section the X-ray tube electrodes and in Fig. 2 in a plan view of the anode schematically reproduced.

Gemäß' der Erfindung sind zwei oder mehrere (in dem abgebildeten Ausführungsbeispiel fünf) Glühkathodenvorrichtungen u, b, c, d, e bezüglich der (Dreh-) Anode f derart angeordnet, daß auf verschiedenen Stellen der um die Achse g drehbaren Anode f verschieden große Brennflecke entstehen. So können den Kathoden a, b, c, d,: e Brennflecke h, i, k, m, n von o, i, 1, 2, 4, 6 qmm zugeordnet sein. Die von diesen Brennflecken ausgehenden Röntgennutzstrahlenbündei haben voneinander verschiedene radiale Richtungen H, T, K, M, N; so daß' mittels dieser Nutzstrahlenbündel an mehreren Arbeitsplätzen Untersuchungen vorgenommen . werden können.According to the invention, two or more (five in the illustrated embodiment) hot cathode devices u, b, c, d, e with respect to the (rotary) anode f are arranged in such a way that at different points of the anode f rotatable about the axis g of different sizes Focal spots arise. Thus, the cathodes a, b, c, d ,: e focal spots h, i, k, m, n of o, i, 1, 2, 4, 6 qmm can be assigned. The bundles of useful X-rays emanating from these focal points have mutually different radial directions H, T, K, M, N; so that 'investigations are carried out at several workplaces by means of this useful beam. can be.

Die neue Röntgenröhre ist wahlweise derart mit einem oder gleichzeitig mehreren Brennflecken betreibbar, daß die Leistungssumme der jeweils eingeschalteten Brennflecke die von der Anode abfuhrbare Leistung nicht übersteigt.The new X-ray tube is either with one or at the same time several focal spots operable that the total power of each switched on The focal point does not exceed the power that can be dissipated by the anode.

Es ist vorteilhaft, zwischen der Anode f und den Glühkathoden ein auf Anodenpotential befindliches, während des Röhrenbetriebes stillstehendes Elek tronenschutzgehäuse o anzuordnen, das den Glühkathoden zugeordnete Blendenöffnungen für den Eintritt der Kathodenstrahlen aufweist.It is advantageous to have one between the anode f and the hot cathode Electrics that are at anode potential and stand still during tube operation tron protective housing o to be arranged, the aperture openings assigned to the hot cathodes for the entrance of the cathode rays.

Es ist ersichtlich; daß-. die neue Röntgenröhre in vorteilhafter Weise nicht nur die Anwendung verschieden großer Brennflecke an sich, sondern auch die gleichzeitige Untersuchung mittels mehrerer von verschieden großen Brennflecken ausgehender Röntgenstrahlenbündel an verschiedenen Arbeitsplätzen gestattet.It can be seen; that-. the new X-ray tube in an advantageous manner not only the use of different sized focal spots per se, but also the simultaneous examination by means of several focal spots of different sizes outgoing x-ray bundles permitted at different workplaces.
