Description

Entladungsröhre mit Gasen oder Dämpfen oder Mischungen aus diesen, insbesondere für Verstärkerzwecke, mit elektrostatisch steuernder, gegen die Entladung isolierter Außensteuerelektrode Die Erfindung betrifft eine Verbesserung an Auß.ensteuerentladungsröhren mit Gasen oder Dämpfen oder Mischungen aus diesen, vor allem solchen, welche für Verstärkerzwecke benutzt werden. Von Innensteuerradioröhren her ist es bekannt, daß die Wirkung :eines Gitters dann am stärksten ist, wenn es zwischen Glühfaden und Anode steht.Discharge tube with gases or vapors or mixtures of these, especially for amplifier purposes, with electrostatically controlling, against the discharge Insulated External Control Electrode The invention relates to an improvement in external control discharge tubes with gases or vapors or mixtures of these, especially those which are used for Amplifier purposes can be used. From inside steering radio tubes it is known that the effect: of a grid is strongest when it is between filament and anode is standing.

Man hat bereits in Radioröhren sog. isolierte Gitter benutzt; auf das me`.allische Gitter war Glas zur völligen Umschließung des Gitters aufgeschmolzen. Hierbei hatten sich große Schwierigkeiten dadurch ergeben, daß das Glas nicht völlig dich! das nichtentgasbare Metall umgab und so eine dauernde Verschlechterung des Vakuums eintrat. Durch Abplatzen einzelner Stellen des Glases wurde die Isolation des Gitters völlig illusorisch.So-called isolated grids have already been used in radio tubes; on the Me'allic grid was glass melted to completely enclose the grid. Here, great difficulties had arisen because the glass was not completely you! surrounded the non-degassing metal and so a permanent deterioration of the Vacuum occurred. The insulation was broken off by individual parts of the glass of the grid completely illusory.

Die Erfindung vermeidet diese Schwierigkeiten.The invention avoids these difficulties.

Erfindungsgemäß wird die Auß.ensteuerverstärkerröhre durch ein doppelwandiges Gefäß gebildet, bei dem die Entladung mit Glühkathode und Anode zwischen beiden Gefäßwänden eingeschlossen ist. Das Gefäß besitzt in seinem Innern einen nach außen offenen Hohlraum, in dem von außen die Steuerelektrode (bzw. Steuerelektroden) angebracht ist bzw. sind.According to the invention, the external control amplifier tube is provided with a double-walled Vessel formed in which the discharge with hot cathode and anode between the two Vessel walls is included. The interior of the vessel has an exterior Open cavity in which the control electrode (or control electrodes) are attached from the outside is or are.

Wie sich durch viele Versuche hat feststellen lassen, benutzt man in derartigen Entladungsröhren für Zwecke der Verstärkung bei höheren Frequenzen mit besonderem Vorteil Gas- resp. Dampfdrucke, welche unter 1/1o mm liegen, wie z. B. für Argon 7 ;< 10-4 mm und für Helium q. y 10-3 mm. Anstatt der Edelgase können auch andere Gase und Dämpfe oder Mischungen derselben mit einem Gesamtdruck von weniger als 1/,o mm verwendet werden.As has been established by many experiments, one uses in such discharge tubes for purposes of amplification at higher frequencies with particular advantage gas resp. Vapor pressures which are below 1/10 mm, e.g. B. for argon 7; <10-4 mm and for helium q. y 1 0-3 mm. Instead of the noble gases, other gases and vapors or mixtures thereof with a total pressure of less than 1 / .o mm can also be used.

Mit Vorteil verwendet man bei derartigen Aurensteuerentladungsröhren Dunkelstrahlerkathoden.It is advantageous to use auric control discharge tubes of this type Dark radiator cathodes.
