A Multi-Megawatt Continuous Wave RF Window for Particle Accelerator Applications

70548 Radio frequency windows, used in nuclear physics experiments, have a poor history of operability. Additionally, existing windows do not have adequate power handling capacity for planned particle accelerators. This project will develop an alternative window design that minimizes sources of stress in RF windows, resulting in significant increases in continuous power handling capabilities. The design will be verified by theoretical techniques, computer simulation, and experimental measurements. Phase I will perform a stress analysis (including both manufacturing and operational) and material studies on a set of preferred window options to determine the optimal window materials and design. An engineering drawing and production plan, including material selection, for the complete window assembly will be provided. Commercial Applications and Other Benefits as described by the awardee: A radio frequency window design, capable of operating predictably and reliably at continuous power levels significantly higher than currently possible, should provide an effective means for increasing power levels in consumer, military, and research applications under development in Europe, Japan, and the United States.
