Abstract: An RF resonator cavity that includes a resonator coil is disclosed. Unlike traditional RF resonator cavities, no sulfur hexafluoride is used in this cavity.

This approach eliminates the use of a potent greenhouse gas, while maintaining the integrity of the cavity. Specifically, the dielectric strength of the vacuum is greater than that of sulfur hexafluoride. This RF resonator cavity may be deployed in a linear accelerator used to implant ions into a workpiece.
