Research Institution
The high-current RF cavities needed for many accelerator applications often are limited by the power transmission capability of the pressure barriers (windows) that separate the cavity from the power source. Most efforts to improve RF window design have focused on alumina ceramic, the most popular historical choice, and have not taken advantage of new materials. In this project, alternative window materials such as sapphire, aluminum nitride, and ALON¿ will be investigated and tested for material properties. The chosen candidate will be used in a window for high power testing. In Phase I, samples of materials that meet the design requirements will be purchased and tested at the Thomas Jefferson National Accelerator Facility. Based on this study, a material will be chosen for Phase II window construction and full power testing. Commercial Applications and other Benefits as described by the awardee: An alternative window material that makes RF windows stronger and more robust should have immediate applications to both superconducting and room-temperature accelerating systems.
