Abstract

Die Elektrode besteht aus einem stiftförmigen Schaft (7) und einem Kopfteil (8), wobei die Elektrode im Bereich ihres entladungsseitigen Endes ein Gefäß (9) für einen Emitter bildet, in dem eine Bohrung (16) angebracht ist, die mit Emittermaterial (10) gefüllt ist. Das Gefäß bildet an seiner entladungsseitigen Stirnfläche einen Kragen, mit einem inneren Kragenteil (13) das zur Bohrung hin konvex gekrümmt ist und einem äußeren Kragenteil (14), das zur Seitenwand des Gefäßes hin konvex gekrümmt ist.
