Abstract
73155S03-I Superconducting particle accelerators require high power radio frequency (RF) couplers that have high capital and operational costs. The operational costs include power dissipation at cryogenic temperatures and operational down time. New coupler designs are needed to reduce these costs for particle accelerators that will require even higher RF power than now available. This project will design a very high power, field-coupled, non-contacting RF transmission line for Superconducting Radio Frequency (SRF) cavities. The design will be applicable to both coaxial and waveguide couplers. Phase I will design and analyze specific, realistic, RF transmission line geometries based on existing and proposed accelerators. The design work will include detailed production plans and drawings. Commercial Applications and Other Benefits as described by awardee: Particle accelerators are an integral part of basic research in high-energy, nuclear, and health sciences, as well as for military and industrial applications. Reduced capital and operating costs for SRF-cavity RF coupling would extend the application of SRF accelerators by providing more cost effective, robust solutions in all these areas.
