无论是在连续波操作还是脉冲模式下，射频超导腔的机械变形都可能是不稳定的根源。电磁场对腔壁施加辐射压力，从而降低谐振频率。腔体的被动硬化可以减少频移。本文对静态和动态失谐进行了分析，并将有关频移的计算结果与高频测量结果进行了成功的比较。最近，计算已为高功率质子腔的设计做出了贡献。
The mechanical deformations of a radiofrequency superconducting cavity could be a source of instability, both in CW operation or in pulsed mode. The electromagnetic fields exert a radiation pressure on the cavity’s walls in such a way to lower the resonant frequency. The cavity’s passive stiffening allows to reduce the frequency shift. In this paper, static and dynamic detuning have been analyzed, the computation results concerning the frequency shift have been compared successfully to the HF measurements. Recently, calculations have been contributed to the design of high power protons cavities.
