Abstract :
The reasons of limitations in field emitter implementation in powerful RF tubes are investigated, overcoming ways are discussed. The results of electron beam optic system (EOS) design with planar type matrices of field emission cathodes and intense beams with power above 100 kW in CW mode are presented.
