Touschek效应是低发射度轻子储存环的主要问题（即，高聚束密度）和低或中等束能量，例如第三代同步加速器光源。Piwinski的公式，其中包括光束形状的变化沿着光束线，这是适合于任何光束能量，已被纳入一个程序，与优雅的使用寿命计算互操作。本文指出了用Piwinski方法求解APS与其它简化方法的区别。此外，由于该公式的通用性，我们还首次将其应用于传输线，以预测光束损失率和光束损失位置。本文还给出了一个可能的能量回收直线加速器升级的APS（APS-ERL）的例子。
The Touschek effect is a major concern for lepton storage rings of low emittance (i.e., high bunch density) and low or moderate beam energy, such as third-generation synchrotron light sources. Piwinski's formula, which includes beam shape variation along the beamline and which is suitable for any beam energy, has been incorporated into a program that interoperates with elegant for use in lifetime calculations. The difference between using Piwinski's method and other simplified methods for the APS is shown in this paper. Furthermore, because of the generality of this formula, we also applied it to transport lines to predict beam loss rates and beam loss locations for the first time. An example related to a possible energy recovery linac upgrade of the APS (APS-ERL) is also given in this paper.
