高频腔体作为强流质子回旋加速器高频系统的重要组成部分,其加速间隙处的高频电压为粒子加速提供能量。当腔体被馈入大功率的高频信号时,腔体各个部分的温度差会引起腔体结构的形变,如果形变量较大,会造成腔体加速间隙处的高频电压的不稳定,影响粒子加速。对于100MeV的高频腔体,其外导体多点固定在磁极上,结构稳固,在下面的计算中,重点 High-frequency cavity as a high-flow proton cyclotron high-frequency system is an important part of the acceleration gap at high-frequency voltage to provide energy for particle acceleration. When the cavity is fed with high-power high-frequency signals, the temperature difference between the various parts of the cavity will cause the deformation of the cavity structure. If the amount of deformation is large, the instability of the high-frequency voltage at the cavity acceleration gap will be caused, Affect particle acceleration. For the 100MeV high-frequency cavity, the outer conductor of the multi-point fixed on the pole, the structure is solid, in the following calculations, the focus
