摘要：
An electron gun asembly comprising direct heated cathodes each having an electron emitting member fixed on a filament which is stretched between a pair of support means disposed face to face with each other on a substrate and a plurality of grid electrodes containing first grids, said cathodes and grid electrodes being secured with predetermined distance with one another by insulative support rods. Each of the cathodes has a means adjusting the spacing between the first grid electrode and the electron emitting member.
