Description

Die vorliegende Erfindung bezweckt die weitere Ausbildung von Röntgenröhren nach dem Patent 331931. Benutzt man nämlich in bekannter Weise als Träger für die Röntgenkathode ein Glasrohr, in der Figur mit 32 bezeichnet, auf welchem man ein mit der Kathode verbundenes Metallrohr 31 befestigt, so genügt, wie Versuche ergeben haben, eine solche Einrichtung nicht, um die Strombahn der zwischen der Glühelektrode 1 und der hinteren Seite des Kathodenspiegels 3 verlaufenden Entladung von dem Metallrohr 31 zu isolieren. Andererseits erwies es sich von Vorteil, mit nur einer Öffnung in der Kathode zu arbeiten und die Strombahn vor dieser Öffnung entsprechend einzuengen.The present invention aims to further develop x-ray tubes the patent 331931. It is used in a known manner as a carrier for the X-ray cathode a glass tube, designated in the figure with 32, on which one with the cathode connected metal pipe 31 attached, so it is sufficient, as tests have shown, a such a device not to the current path between the glow electrode 1 and the Discharge from the metal tube 31 running towards the rear side of the cathode mirror 3 isolate. On the other hand, it was found to be advantageous to have only one opening in the cathode to work and to narrow the current path in front of this opening accordingly.

Die Größe dieser Öffnung hängt von der erwünschten Größe des Brennpunktes ab. Sie wird also für Therapieröhren größer, für Röhren, die scharfe Bilder geben sollen, kleiner genommen.The size of this opening depends on the desired size of the focal point. she So it gets bigger for therapy tubes, for tubes, which should give sharp images, taken smaller.

Aus den eingangs erwähnten Gründen wird gemäß, der Erfindung das aus Quarz, Hartglas oder Porzellan bestehende Rohr 33 eingefügt, welches vorn konisch verjüngt und in den Kathodenspiegel 3 eingeschliffen ist. Es hat hinter der Schlifffläche einen Wulst, der es gestattet, mittels des auf die Kathode 3 aufgeschraubten Rohres 31 den Schliff fest mit dem Kathodenkörper zu verbinden. Um die Entladung zu verhindern, in unerwünschter Weise den Weg zwischen den Rohren 32 und einzuschlagen, sind Metallringe 34 zwischen diese beiden Röhren eingelegt. Diese können entweder aus Metallrohr bzw. Blech hergestellt sein oder aber vermittels Auftragens von Metallschichten auf die Rohre 33 oder 32 in einer der Arten, wie sie zur Herstellung von Metallspiegdln in der Technik geläufig sind.For the reasons mentioned at the outset, according to the invention, that made of quartz, hard glass or porcelain existing tube 33 inserted, which tapers conically in front and in the cathode mirror 3 is ground in. It has a bulge behind the ground surface that it allows, by means of the tube 31 screwed onto the cathode 3, firmly with the ground joint to connect the cathode body. To prevent the discharge, in undesirable Way to take the path between the tubes 32 and 32, metal rings 34 are between inserted these two tubes. These can either be made of metal pipe or sheet metal or by applying metal layers to the tubes 33 or 32 in FIG one of the types that are commonly used in technology for the production of metal mirrors.
