Description

  

      Antikathode    für Röntgenröhren.    Bei solchen Röntgenröhren, bei denen die  Antikathode mit der Kathode in derselben  Achse liegt, muss die Vorderfläche der Anti  kathode meistens unter 45   gegen die Achse  abgeschrägt sein. Wenn nun eine solche Anti  kathode mit Wasserkühlung betrieben werden  soll, so ist es erwünscht, die Wandung der  selben möglichst überall gleich stark zu ma  chen. Dieses stösst jedoch an der vordern  Fläche, also gerade dort, wo     die,    Wärme er  zeugt wird, auf Schwierigkeiten, weil es nur  ausserordentlich schwer und umständlich mög  lich ist, etwa durch Bohren eine Höhlung im  Innern des aus Metall, und zwar meistens  aus Kupfer bestehenden     Antikathodenkörpers     herzustellen, welche der äussern Form der  Antikathode entspricht.

   Die vorliegende Er  findung vermeidet nun diesen Übelstand, in  dem sie als Antikathode eine nahtlos gezogene _  Hülse verwendet, deren Boden gegen die Achse  abgeschrägt ist.  



  Die beiliegende Zeichnung     veranschaulicht     ein Ausführungsbeispiel des Gegenstandes der  Erfindung. Die Antikathode 1 der Röntgen-    röhre mit dem Platinspiegel 2 ist mittelst  eines aufgelöteten Platinringes 3 in das Glas  rohr 4 eingeschmolzen und durch dieses mit  dem übrigen Glaskörper der Röntgenröhre       verbunden.    Der innere Hohlraum 5 ist mit  Wasser gefüllt.

   Es ist ohne weiteres ersicht  lich, dass bei der vorliegenden Form die Vorder  fläche, an der hauptsächlich die abzuleitende  Wärme erzeugt wird, auch nicht wesentlich  dicker auszufallen braucht als die Seiten  wände, so dass also der von der Wärme im  Metall zurückzulegende Weg in beliebiger  Weise beschränkt und eine ausserordentlich  intensive Kühlung des     Antikathodenspiegels     erreicht werden kann.



      Anti-cathode for X-ray tubes. In the case of such X-ray tubes in which the anticathode lies in the same axis as the cathode, the front surface of the anticathode must usually be beveled at 45 ° to the axis. If such an anti-cathode is to be operated with water cooling, it is desirable to make the wall of the same as equally strong as possible everywhere. However, this encounters difficulties on the front surface, i.e. precisely where the heat is generated, because it is extremely difficult and cumbersome, for example by drilling a cavity inside the metal, mostly made of copper to produce an existing anti-cathode body, which corresponds to the external shape of the anti-cathode.

   The present invention avoids this inconvenience by using a seamlessly drawn sleeve as an anticathode, the bottom of which is beveled towards the axis.



  The accompanying drawing illustrates an embodiment of the subject matter of the invention. The anticathode 1 of the X-ray tube with the platinum mirror 2 is fused into the glass tube 4 by means of a soldered-on platinum ring 3 and connected to the rest of the glass body of the X-ray tube through this. The inner cavity 5 is filled with water.

   It is readily apparent that in the present form, the front surface, where the heat to be dissipated is mainly generated, does not need to be significantly thicker than the side walls, so that the path to be covered by the heat in the metal can be any way limited and an extremely intensive cooling of the anticathode mirror can be achieved.
