摘要：

This paper illustrates the design and simulation of a unique 500 MHz single-cell superconducting radio frequency cavity with a fluted beam pipe and a coaxial-type fundamental power coupler. The simulation results show that the cavity has a high r/Q value, a low peak surface field and a large beam aperture, so it can be a candidate cavity for high current accelerators. With the help of a fluted beam tube, almost all the higher order modes can propagate out of the cavity, especially the first two dipole modes, TE111 and TM110, and the first higher monopole mode, TM011. The external quality factor of the coaxial fundamental power coupler is optimized to 1.2x10(5), which will be useful when it is applied in the light source storage ring.
