Abstract
A traveling wave tube arrangement for use in satellite communications systems is disclosed wherein a plurality of traveling wave tube delay structures and an electron gun are contained in a single envelope with beam deflection apparatus. The electron beam deflection apparatus is disposed between the electron gun and the plural traveling wave tube delay structures to selectively deflect the electron beam to the individual delay structures on a time division basis. In one embodiment, electron beam deflection apparatus is simplified by arranging the individual delay structures radially from a point in the path of the electron stream where the stream is deflected by the beam deflection apparatus.
Claims8
A traveling wave tube arrangement comprising an electron (10) gun capable of generating a beam (15) of electrons,
- a first delay structure (20) capable of receiving and modulating the beam of electrons,
- CHARACTERIZED IN THAT
- the traveling wave tube arrangement further comprises
- n-1 additional delay structures (30), where n is greater than 1, each additional delay structure being disposed so as to be capable of receiving and modulating the beam of electrons;
- and
- deflecting means (40) disposed between the electron gun and the n delay structures, said deflecting means selectively deflecting the beam of electrons to any one of the n delay structures.
