Abstract：
The transient response analysis of the SLED based on the equivalent circuit is described. Then, a C-band SLED using TE_0,1,15 mode cylindrical cavity with TE₁₀-TE₀₁ mode converter has been designed. According to the main RF parameters of the accelerator, the coupling coefficient is optimized to obtain the maximum multiplication factor. The key components of the pulse compressor include a 3 dB directional coupler, a TE₁₀-TE₀₁mode converter, and a cylindrical cavity, which are simulated and optimized using 3D electromagnetic field simulation software. In addition, the function defining the relation between the coupling factor and aperture size is derived by a mathematical fitting method.
