超导RF腔的发展目前正在进行的新的加速器项目在欧洲核子研究中心，如HIE ISOLDE和HL-LHC。需要机械RF调谐系统来补偿由于温度、机械、压力和RF对腔几何形状的影响而引起的腔的腔频率偏移。为现有RF腔体开发的此类机械调谐器具有丰富的历史和经验。在HIE ISOLDE和HL-LHC的背景下，如所需的分辨率，空间限制，可靠性和可维护性的设计约束，导致了新的概念的调整机制。本文将讨论这种新的方法，其性能和计划的发展。
Superconducting RF cavity developments are currently on-going for new accelerator projects at CERN such as HIE ISOLDE and HL-LHC. Mechanical RF tuning systems are required to compensate cavity frequency shifts of the cavities due to temperature, mechanical, pressure and RF effects on the cavity geometry. A rich history and experience is available for such mechanical tuners developed for existing RF cavities. Design constraints in the context of HIE ISOLDE and HL-LHC such as required resolution, space limitation, reliability and maintainability have led to new concepts in the tuning mechanisms. This paper will discuss such new approaches, their performances and planned developments.
