摘要
SRF cavities are the common accelerating structures for many accelerators nowadays.Since a series of external loads on the resonator walls predetermine the main working conditions of the SC cavities,the detailed investigation of their mechanical properties should be conducted in parallel with the main RF design.The effects of very high electromagnetic fields that result in strong Lorentz forces and the pressure on cavity walls from the helium tank that also deforms the cavity shape,the tuning scheme resulting in the change of accelerating field profile and mechanical eigen resonance of cavities which are the main source of the microphonics must be taken into account during integrated design of the resonator and its liquid helium vessel.
