  Einrichtung zur Erzeugung von Röntgenstrahlen konstanter Härte. 



   Bei dem Betrieb von Röntgenröhren ändert sich bekanntlich die   Strahlenqualit t   fort-   während   mit der unvermeidlichen Änderung des Gasdruckes innerhalb der Röhre ; es 1 nn daher eine solche Röhre nicht längere Zeit hindurch demselben Zwecke dienen. Im allgemeinen werden

 erwünscht ist. 



   Nach vorliegender Erfindung wird der Stromübergang zwischen den Elektroden der Röhre von dem zufällig vorhandenen Gasrete unabhängig gemacht. 



   Es   wurde schon vorgeschlagen, für denselben Zweck die Antikath'de   zu erhitzen,   oder   auch die Verwendung einer durch einen besonderen Srromkreis zu heizenden Kathode oder Wehnelt-Kathode, doch bringen diese Methoden eine Reihe   von   Missständen   mit sich. die f-mer   praktischen Durchführung hinderlich im Wege stehen.

  Device for generating X-rays of constant hardness.



   When X-ray tubes are in operation, it is known that the radiation quality changes continuously with the inevitable change in the gas pressure inside the tube; Therefore such a tube cannot serve the same purpose for a long time. Generally will

 is desired.



   According to the present invention, the current transfer between the electrodes of the tube is made independent of the gas that happens to be present.



   It has already been proposed to heat the anticathode for the same purpose, or also to use a cathode or Wehnelt cathode to be heated by a special circuit, but these methods involve a number of drawbacks. the f-mer practical implementation stand in the way.
