尾流势积分的间接方法
Indirect methods for wake potential integration
摘要：
现代加速器和自由电子激光工程的发展要求考虑任意三维结构中超短束团的尾流场。用直接积分的方法计算尾流场是困难的，因为散射场需要很长时间才能赶上聚束。另一方面，到目前为止，文献中还没有通用的间接尾流场积分算法。本文综述了旋转对称和空腔状三维结构中尾流势的间接计算方法。对于任意的三维几何形状，我们介绍了几种新的技术，并测试它们的数值。
英文摘要：
The development of the modern accelerator and free-electron laser projects requires to consider wake fields of very short bunches in arbitrary three dimensional structures. To obtain the wake numerically by direct integration is difficult, since it takes a long time for the scattered fields to catch up to the bunch. On the other hand no general algorithm for indirect wake field integration is available in the literature so far. In this paper we review the known indirect methods to compute wake potentials in rotationally symmetric and cavity-like three dimensional structures. For arbitrary three dimensional geometries we introduce several new techniques and test them numerically.
