The effect of space charge in bunches stored for many synchrotron oscillations combined with the nonlinear resonances in a storage ring may create a particle diffusion to large amplitudes and eventually create unwanted beam loss. We review and discuss the mechanism which creates beam loss with the focus on how to estimate the number of particles that will be crossed by the stable fixed lines generated by a coupled resonance and space charge.

空间电荷、非线性共振和光束损耗

为许多同步加速器振荡而存储的空间电荷束效应与存储环中的非线性共振相结合，可能会产生大振幅的粒子扩散，并最终产生不需要的束流损失。我们回顾并讨论了产生束流损失的机制，重点是如何估计由耦合共振和空间电荷产生的稳定固定线将穿过的粒子数量。
