拟议的 TESLA 线性对撞机将使用长束列车。这些束串的一次性阻尼需要一个周长为 17 公里、中等能量为 3-5 GeV 的阻尼环。这种不寻常的大周长与能量之比导致相当大的不相干空间电荷调谐偏移，这反过来又导致垂直发射率的增加。将讨论减少空间电荷力的可能解决方案。通过数值模拟研究它们的优点和问题。
The proposed TESLA linear collider will use long bunch trains. Damping of these bunch trains at once requires a damping ring with a large circumference of 17 km and a moderate energy of 3-5 GeV. This unusual large ratio of circumference to energy leads to a considerable incoherent space charge tune shift, which in turn leads to an increase of the vertical emittance. Possible solutions to reduce the space charge force will be discussed. Their benefits and problems are investigated through numerical simulations.
