MODEL CONVERTER DEVICE AND POWER DIVIDER FOR MICROWAVE TUBE AND MICROWAVE TUBE COMPRISING SUCH A DEVICE.

摘要

P Mode converter and power divider for electronic tube. These tubes will have an outlet cavity in the form of a revolution, and a hollow electron beam which propagates along the axis of revolution. The device comprises secondary waveguides arranged with an azimuthal symmetry in the outlet cavity, each guide having coupling holes on its external wall, arranged so as to excite a desired mode inside the guide. According to one characteristic, the electronic tube operates in a TEm mode, n with a high azimuth index m, and the number 1 of the secondary guides 1 = m. According to other characteristics: the secondary guides are of trapezoidal section; the guides are excited in the fundamental mode; the guides are fitted with individual microwave windows outside the electron tube. Application to gyrotrons for heating plasmas. /P
