Description

In der Patentschrift 417 225 ist eine"Glimmlichtentladungsröhre mit Gasfüllung beschrieben, bei welcher die Zerstäubung des Kathodenmaterials und die Gasabsorption dadurch - auf ein Mindestmaß gebracht ist, daß der in bestimmter Weise zerteilte Kathodenkörper den von der.Anode ausgehenden Ionen nur sehr wenig Auftrefffläche darbietet, die Ionen vielmehr hauptsächlich in den Zwischenräumen des Kathodenkörpers aufgefangen werden. Zugleich wird durch diese Anordnung der Kathodenfall merklich herabgesetzt.In patent specification 417 225 is a "glow light discharge tube described with gas filling, in which the sputtering of the cathode material and the gas absorption thereby - Is brought to a minimum that the cathode body divided in a certain way presents only a very small area of impact to the ions emanating from the anode, the ions rather, they are mainly collected in the interstices of the cathode body. At the same time, the cathode drop is noticeably reduced by this arrangement.

Eine vorteilhafte Herstellung von Kathoden für solche Röhreu besteht gemäß der Erfindung darin, daß der poröse Kathodenkörper aus kleineren gleichförmigen Gitterscheiben oder Gitterzylindem aufgebaut wird.An advantageous production of cathodes for such tubes consists according to the invention in that the porous cathode body consists of smaller, uniform lattice disks or lattice cylinders.

Abb. ϊ der Abbildungen stellt eine derartige Röhre dar, bei welcher die Anode A als .Scheibe ausgebildet ist und erfmdungsgemäß die Kathode ίζ einen aus Gitterscheiben aufgeschichteten., durchweg porösen Körper darstellt. Gemäß Abb. 2 hat die Anode.4 die Form eines in der Röhrenachse angeordneten Stabes, und die Kathode K ist erfindungsgemäß aus Gitterzylindern aufgeschichtet, so daß sre einen durchweg; porösen Zylinder von einiger Dicke bilde1 Fig. Ϊ of the figures shows a tube of this type in which the anode A is designed as a disk and, according to the invention, the cathode ίζ is a consistently porous body made of lattice disks. According to Fig. 2, the anode.4 has the shape of a rod arranged in the tube axis, and the cathode K is, according to the invention, stacked up from lattice cylinders, so that there is one throughout; porous cylinder of some thickness form 1

Die Gitterscheiben und Gitterzylinder sind mittels Webverfahrens leicht herstellbar. Sk werden nach der Aufschichtung durdh Drähte miteinander verbunden, so daß die Kathode einen einheitlich eiinsetzbaren. Körpier darstellt.The lattice disks and lattice cylinders are easy to manufacture using a weaving process. Sk are connected by wires after the layering, so that the cathode a uniformly applicable. Represents body animal.
