Description
The high-energy linac of the Future Circular Collider electron–positron (FCC-ee) injector requires high-performance RF accelerating structures to efficiently reach 20 GeV with stable operation. A tapered travelling-wave structure operating at 3 GHz has been designed to optimize accelerating performance and suppress wakefields.
This work focuses on the development of a full 3D model of the accelerating structure, including the RF power couplers, to ensure efficient power transfer and reliable high-power operation. Several coupling strategies were investigated to achieve a compact design while minimizing higher-order multipole components in regions lacking axial symmetry.
