High-Power Radio Frequency Window

72383S03-I Conventional waveguide windows have power-handling limitations that severely restrict linear accelerator performance. This project will develop a novel microwave window concept that directly addresses the electrical and thermal stress limitations of conventional waveguide windows, leading to improvements in both peak and average power-handling capability. Phase I will develop a design theory for this new window concept and, as an example, provide a design for a specific linear accelerator application. In Phase II, a prototype high-power radio frequency window will be developed and tested at the linear accelerator laboratory for which the Phase I design example was created. Commercial Applications and Other Benefits as described by awardee: The microwave window should be readily implemented at linear accelerator laboratories that have an existing need for windows with higher power-handling capability.
