چکیده انگلیسی
RF cavity which establishes an electric field to accelerate the charged particles is one of the most critical and complicated components in cyclotron. When the cavity is in a high-power operation, there will be a high temperature in RF cavity due to its own thermal loss. And it will cause mechanical deformation and frequency deviation to cavity. Those series of factors may influence the performances of cavity negatively. In this paper, thermal situation of RF cavity has been analyzed during high-power operation, and some optimizations are made to improve thermal performance. Frequency deviation of cavity is simulated through multi-physics analysis. Moreover, a low-power (â¼20 kW) test has verified the thermal consideration, and the performances of prototype cavity in high-power operation which are estimated comply with the design goal.
