Abstract (en)

The X-ray tube includes an arrangement for producing and focusing an electron ray (5) on a target material. The target comprises a gaseous or steam material, at least during the operation of the tube, which is enclosed under pressure in a chamber (6), at least partially transparent for electron ray and X-ray radiation. The target comprises preferably a heavy metal, such as quicksilver.

Abstract (de)

Es wird eine Röntgenröhre mit einer Einrichtung zur Erzeugung und Fokussierung eines Elektronenstrahls (5) auf ein Targetmaterial beschrieben. Ausgehend von der Problematik einer unzulässigen Erhitzung der Anode (3) bei einer Steigerung der Elektronenstrahldichte dient erfindungsgemäß ein gasförmiges, in einer Kammer (6) eingeschlossenes Targetmaterial zur Erzeugung der Röntgenstrahlung, das wesentlich stärker erhitzt werden kann, ohne daß die Anode beschädigt wird. <IMAGE>
