摘要
由于空间电荷效应的强度与洛伦兹系数呈陡峭的反比关系，因此在超相对论电子储存环中的空间电荷效应是无关紧要的，这是一个公认的真理。然而，随着衍射极限的推进，最先进的光源正在接近这样一个点：它们的发射率变得如此之小，以至于空间电荷力再也无法被忽视。在本文中，我们以第四代光源 PETRAIV 和 SOLEIL II 为例，展示了空间电荷效应如何影响注入动力学、动态孔径和集束稳定性。
It is a truth universally acknowledged, that space charge effects in
ultrarelativistic electron storage rings are irrelevant due to the steep
inverse dependence of their strength on the Lorentz factor. Yet, with the push
towards the diffraction limit, the state-of-the-art light sources are
approaching the point where their emittance becomes so small that the space
charge force can no longer be ignored. In this paper, we demonstrate how space
charge effects affect the injection dynamics, dynamical aperture, and
collective beam stability on the example of 4th generation light sources PETRA
IV and SOLEIL II.
