  Schaltungsanordnung zum Schutz von Röntgenröhren vor schädlicher Aufladung. 



   Röntgenstrahlenröhren, insbesondere solche, die zur Erzeugung harter (durchdringungs-   fähiger)   Röntgenstrahlen geeignet sind, also   verhältnismässig   grossen Durchbruchswiderstand aufweisen, nehmen, sobald sie betrieben werden, leicht elektrische Ladungen an, die bei den bisher bekannten Schaltungsanordnungen der Röntgenröhren auf ihnen verbleiben und ihr einwandfreies Arbeiten, insbesondere ihre Betriebssicherheit beeinträchtigen. 



   Dieser Nachteil wird durch die Erfindung beseitigt, die darin besteht, dass beide Elektroden der Röntgenröhre unmittelbar mit je einer Klemme zweier Stromquellen beispielsweise zweier Transformatorsekundärwicklungen verbunden sind, zwischen deren beide anderen Klemmen die Vorrichtungen (Ventilröhren. umlaufende Schaltvorrichtungen

  Circuit arrangement for protecting X-ray tubes from harmful charging.



   X-ray tubes, especially those that are suitable for generating hard (penetrable) X-rays, i.e. have a relatively high breakdown resistance, as soon as they are operated, easily accept electrical charges that remain on them with the previously known circuit arrangements of the X-ray tubes and their flawless Work, in particular affect their operational safety.



   This disadvantage is eliminated by the invention, which consists in that both electrodes of the X-ray tube are directly connected to one terminal each of two power sources, for example two transformer secondary windings, between the two other terminals of which the devices (valve tubes, rotating switching devices
 EMI1.1
   The X-ray tube is then protected from harmful charges, since it is directly connected to conductors on both sides with regularly more capacitance than conductors (the sources of electricity) which they themselves have.



   One embodiment of the new circuit arrangement is shown schematically in the drawing
 EMI1.2
 of the two secondary windings a and b of two inductors c and J are connected. The direction that is undesirable for keeping the voltage pulses away, i.e. every second or a larger number of voltage wave halves from the X-ray tube. here from the one that also drives a circuit breaker f rotating in the primary circuit in a known manner
 EMI1.3
 When you pass the ladders that are not moving, lay them against each other so that they are conductive.



  PATENT CLAIMS:
1 Circuit arrangement to protect X-ray tubes from bad charging during operation, characterized in that the two electrodes of the X-ray tube are each connected directly to a terminal of two power sources, between whose other terminals the devices used to control the power supply to the X-ray tube are connected .
