Superconducting elliptical Radio Frequency (RF) cavities are proposed to accelerate proton beams in Future Circular Collider (FCC-hh). In this project, I focus on using Poisson Superfish for 2D simulation to optimize the geometrical parameters - dome and iris ratios of single-cell superconducting elliptical RF cavities to generate specified optimum figures of merit:
- Resonant Frequency
- Peak Electric Fields on the cavity surface
- Peak Magnetic Fields on the cavity surface
- Quality Factor
Comparative studies between Poisson Superfish (2D simulation) and CST Microwave Studio (3D simulation) have verified our optimization results in which the optimum dome and iris ratios are 0.74 and 0.51 respectively. The analysis demonstrates the capabilites of Poisson Superfish in tuning and optimizing geometrical parameters for elliptical RF cavities by achieving optimum figures of merit.
