Abstract

Eine Ionisationskammer für radiometrische Meßeinrichtungen, insbesondere für traversierende Flächenmassemeßsysteme soll geschaffen werden, die eine hinreichende Empfindlichkeit besitzt und dabei die bei Ionisationskammern üblichen guten Werte hinsichtlich Vakuumdichtigkeit, Grundstrom und Temperaturabhängigkeit liefert. Innerhalb des Gehäuses (3) eine Mehrzahl benachbarter und gegenseitig abgegrenzter Abschnitte (2) mit den jeweiligen Sammelelektroden (6) unterteilt. Die Sammelelektroden (6) sind mit elektrischen Anschlüssen (14) verbunden, die durch den Isolator (13; 17) einer gasdichten Mehrfach-Durchführung hindurch nach außen geführt sind und daß der Isolator (13; 17) mit einem die elektrischen Anschlüsse (14) gemeinsam umgebenden elektrisch leitfähigen Bereich versehen, der sowohl gegenüber dem Gehäuse (3), als auch den Anschlüssen (14) elektrisch isoliert angeordnet ist, jedoch im stromlosen Zustand auf Elektrodenpotential liegt.
