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, TE 111 and TM 110 , and the first higher monopole mode, TM 011 . The external quality factor of the coaxial fundamental power coupler is optimized to 1.2 × 10 5 , which will be useful when it is applied in the light source storage ring.
