摘要: The cathode has an emitter i.e. flat (1), arranged in a head for emitting electrons during applying of filament voltage. An end region (4) the is positioned by fixed bearing (5), and another (6) limited at thermal main expansion plane floating (7). are formed as electric contacts longitudinal axis emitter. provided with column-like support element (51) attachment member (52).
