ABSTRACT:
The invention is a mode converter and power splitter device for electron tubes, particularly gyrotrons and tubes of similar categories. These tubes have an output cavity 2, which is a circular form about a centerline, and a hollow electron beam 1 which propagates along the same centerline. The device complying with the invention is a structure which comprises secondary wave guides 6, symmetrical in azimuth around the same centerline as the outlet cavity, each guide 6 containing coupling apertures 7 on its outer wall (that furthest from the centerline), these apertures 7 being arranged to excite a given mode in the guide. One important embodiment of the invention is that the electron tube operates in a TE.sub.m,n mode with a high azimuth index m and the number of secondary guides 1=m. Another important embodiment of the invention is that secondary guides 6 are trapezoidal in section. Another important embodiment of the invention is that secondary guides 6 are excited in the fundamental mode. Another embodiment of the invention is that the secondary guides can include individual microwave windows 58 outside the electron tube. The invention may find application for plasma heating for thermonuclear fusion and particle accelerators.
