    Abstract: Kaltkatoden-lonisationsmanometer zur Druckmessung im Vakuum, das nach dem inversen Magnetron-Prinzip arbeitet und zur Erfassung von Drücken im Fein-, Hoch- und Ultrahochvakuumbereich (vorzugsweise zwischen 10 Pa und 1 Pa) eingesetzt wird. Die Kontaminationsneigung soll verringert und dadurch die Standzeit dieser Messröhren verlängert werden. Dies wird durch eine Messröhre erreicht, die mit zwei separat angesteuerten Katoden (K1, K2) und einer gemeinsamen Anode (A) augestattet ist und wodurch in deren Inneren zwei voneinander unabhängige Entladungen gezündet werden können. Während eine direkt am Messröhreneingang lokalisierte Entladung (K1) die Funktion einer Gasreinigungsvorrichtung übernimmt, in der über plasma-chemische Dissoziationsreaktionen in die Messröhre eintretende Kohlenwasserstoff- oder andere kontaminierende Dämpfe gekrackt bzw. polymerisiert werden, fungiert eine zweite (K2) im Messröhrengehäuse (MRG) untergebrachte und durch diese Gasentladungsstrecke (K1) abgeschirmte Entladungskammer als eigentliche Messkammer. Nur der aus dieser Entladungszone (K2) abfliessende Entladungsstrom wird ausgewertet und zur Druckmessung herangezogen. Durch diese spezielle Doppelkammer-Messröhrengeometrie wird erreicht, dass das Plasma in der eigentlichen Messkammer (K2) unter weitestgehend sauberen Bedingungen brennt, weshalb die eine höhere Standzeiten der Messröhre erzielt wird.

    Abstract: A cold cathode ion gauge is provided that is suitable for use in a high vacuum and in the presence of contaminating gases. By decreasing the discharge current and, more precisely, decreasing the charge current density received by the gauge electrodes, and using certain type of materials for the gauge electrodes, the mechanism by which insulating films are deposited on surface of the electrodes is attenuated and the life of the gauge is significantly prolonged. The gauge discharge current can be decreased by providing a large resistor in series with the anode, while the charge current density can be decreased by using an electrode with larger surface area, which can be achieved by fabricating grooves or fans on electrodes and by using low electron backscattering and low secondary emission materials, like carbon. Another concept of constant current mode is also proposed in this invention for extending the lifetime of CCIGs that are used for vacuum containing unfriendly gases.

    Abstract: The present invention relates to an ionisation vacuum gauge for measuring the residual pressure of a gaseous material remaining in a container (10), more particularly after operation of a vacuum pump. The gauge comprises an electron-emitting cathode (31) made by exploiting the nanotube technology, a grid (13; 33; 133; 133') for accelerating the electrons emitted by the cathode, and a plate (15; 35) collecting the ions and/or the ionised positive molecules of the gas. Measuring the plate current by a galvanometer allows determining the value of the residual pressure inside the container.
