Abstract
The current design for the rf couplers for the ILC cavity introduces unacceptable emittance growth in the beam. We have developed two new couplers designed to mitigate the emittance growth problem by preserving the axial symmetry of the cavity fields. Optimization of the design of the coaxial coupler units. Complete analysis of the ILC structure with the new coupler units was performed to confirm its electrodynamic properties. Conceptual mechanical design of the coupler units. Choice of optimal configuration of the accelerating cavity and couplers. Optimization of coaxial coupler units to achieve the required damping of parasitic modes. Complete electromagnetic analysis of the ILC cavity incorporating our coupler designs. Analysis of multipactor effects in the devices. Selection of optimal design. Commercial applications and benefits: The ILC cavities require a coupler with no back kick from higher order modes in order to preserve the beam emittance and hence the luminosity of the collider. We have proposed here a coupler design that can successfully achieve the requirements of the ILC
