摘要

我们开发并介绍了用于计算环形加速器(尤其是同步辐射光源)动态孔径和动量接受的新算法。光栅图形中的填充工具启发我们通过最小化稳定初始坐标上所需的跟踪来高效计算动态孔径,从而比标准算法提高了几倍的速度。我们开发了一种用于动量接受计算的新技术--快速 Touschek 跟踪。利用现代加速器代码进行的全面基准测试表明,新技术可以将局部动量接受的计算速度提高一到两个数量级,而且精度损失有限。

Efficient algorithms for dynamic aperture and momentum acceptance calculation in synchrotron light sources
New algorithms useful for the calculation of dynamic aperture and momentum acceptance in circular accelerators, particularly synchrotron light sources, are developed and presented. The flood-fill tool from raster graphics inspired us to efficiently compute dynamic apertures by minimizing required trackings on stable initial coordinates, leading to several factors of speedup with respect to standard algorithms. A novel technique for momentum acceptance calculations, Fast Touschek Tracking, is developed. Thorough benchmarking using modern accelerator codes shows that the new technique can provide one or two orders of magnitude faster computation of local momentum acceptances with only limited loss of accuracy.
