Abstract

This invention relates to electronic engineering, to be exact, to thermionic cathodes of electronic tubes and can be used as an electron-emitting source in electron-beam tubes including in kinescopes, oscillographic, radar and other tubes used a high-density E-beam. In this invention for account of design features there manufactured emitter bodies connected to glowers and placed headers (cross head) where glowers ends are fixedly attached.
