Design of RF-cavities for CW operation

Funnels are a key component of accelerators proposed for transmutation technologies. In addition to conventional accelerator elements, specialized rf-cavities are needed in a funnel. Simulations were done to obtain their electromagnetic field distribution and to minimize the rf-induced heat loads. Using these results a structural and thermal analysis of these cavities was performed to insure their reliability at high average power and to determine their cooling requirements.
