A numerical synthesis method for optimization of the key components of the transmission line for high‐power fusion gyrotron is proposed in this paper. Combined with the analysis method, an algorithm has been developed for the waveguide to provide higher power transformation efficiency, which is 99.447% and 99.9721% for the TE₀₁‐TE₁₁ mode converter and TE₁₁ taper, respectively. The synthesis method has been tested for the designed key components of transmission line to transfer the electromagnetic wave from the gyrotron output port to the specified position of the sample to be heat. The experimental results show that the output mode is in excellent agreement with theoretical calculation. The details are presented for the circular waveguide mode converter and the layout of the whole system.
