Abstract

Ein Rahmen (10) für eine Kathoden/Steueranordnung (14) weist Bohrungen auf, in die Haltestifte (12) eingesetzt sind. Es handelt sich um den ohnehin vorhandenen Rahmen, der eine Steuerscheibenanordnung (16) trägt.
Dadurch, daß der ohnehin vorhandene Rahmen und nicht eine gesonderte Halteanordnung, wie bisher, verwendet wird, ist der Gesamtaufbau der Kathoden/Steueranordnung besonders ein­ fach.
