TWO-RANGE TRAVELLING WAVE LAMP Russian patent published in 2010 - IPC H01J25/34 

FIELD: electrical engineering.

SUBSTANCE: two-range high-power travelling wave lamp (TWL) incorporates electron gun generating electron beam, two sections of circuits of electron-beam coupled resonators, power input and output in every section, electric or permanent magnets and collector of "waste" electron beam. Aforesaid sections feature different bandpass and different amplified frequency bands, and different sizes. Decoupling section with magnets is arranged between said sections to eliminate beam modulation induced in TWL first section. Each section incorporates its power input and output.

EFFECT: expanded performances.
