在圆形加速器中，由于空间电荷的作用，粒子的调谐可能会越过共振线。自洽处理除了考虑驱动场误差外，还需要考虑随时间变化的空间电荷力。这是通过线性和非线性共振的计算机模拟来研究的。讨论了与无空间电荷的共振交叉相比的新特点。在偶极共振的情况下，发现空间电荷具有稳定效应，而它可能导致对非线性共振的不希望的调谐锁定。
In circular accelerators the tune of a particle may cross a resonance line due to space charge. A self-consistent treatment requires taking into account the time-dependent space charge force in addition to the driving field errors. This is investigated by means of computer simulation for linear and non-linear resonances. The new features as compared with resonance crossing in the absence of space charge are discussed. In the case of a dipole resonance space charge is found to have a stabilizing effect, whereas it can lead to undesirable tune locking for non-linear resonances.
