射频腔是回旋加速器中最关键和最复杂的部件之一，它建立一个电场来加速带电粒子。当腔处于高功率工作状态时，由于其自身的热损耗，在高频腔内会产生较高的温度。并且会对腔体造成机械变形和频率偏差。这一系列因素可能会对腔体的性能产生负面影响。本文分析了高频腔在高功率工作时的热情况，并对其进行了优化，以提高其热性能。通过多物理分析对腔体的频偏进行了模拟。此外，还进行了低功耗(∼20kW)的测试，验证了热设计的可行性，估算出的样机腔体在高功率工作时的性能符合设计目标。
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 (∼ 20 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.
