论文摘要
我们简要介绍了我们的算法及其实施的最新进展，其实现称为SIMPA，在上一篇论文中描述了。该算法具有新的独特方法，可用于在任意静态电磁场中对带电颗粒的长期4D跟踪。使用本文所述的改进，我们在Elena进行了频率分析和动态孔径研究。显示了电子冷却器的磁系统对动态孔径引入的末端场的影响和扰动。这项研究的一个特殊特征是我们尚未在模型中引入任何多极误差。本文计算的动态孔径是磁元素几何形状的直接结果。根据结果，我们提出一些建议，以减少梁减速期间的损失。
We briefly present recent progress with our algorithm and its implementation called SIMPA described in a previous paper. The algorithm has a new and unique approach to long-term 4D tracking of charged particles in arbitrary static electromagnetic fields. Using the improvements described in this paper, we made frequency analysis and dynamic aperture studies in ELENA. The effect of the end fields and the perturbation introduced by the magnetic system of the electron cooler on dynamic aperture is shown. A special feature of this study is that we have not introduced any multipole errors into the model. The dynamic aperture calculated in this paper is the direct consequence of the geometry of the magnetic elements. Based on the results, we make a few suggestions to reduce the losses during the deceleration of the beam.
