Experiment on Gyrotron Traveling Wave Tube with Inner Mode Converter in W-band TE02 Mode

This paper explicates the experimental research of W-band $TE_{02}$ mode gyrotron traveling wave tube interaction, discussing the reasons for adopting TE02 mode as the working mode, the existing competitive modes, the high-frequency structure adopted, the simulation of the interaction, and the design of the inner mode converter. Finally, the test results are given.
