摘要:

精密储存环实验需要一套用于跟踪程序的分析基准。为了确定精确的跟踪程序在电和磁环的准确性,各种分析估计的环中的粒子和自旋动力学,并比较跟踪模拟的数值结果。初步比较中的差异表明,有几项分析估计数需要改进。作为一个例子,我们发现四阶Runge-Kutta/Predictor-Corrector方法速度慢但准确,并且它通过了所有测试基准,通常达到十亿分之一的水平。因此,基于四阶龙格-库塔/预测-校正积分的高精度分析估计和跟踪程序可以用于基准测试更快的跟踪程序的准确性。

英文摘要:

A set of analytical benchmarks for tracking programs is required for precision storage ring experiments. To determine the accuracy of precision tracking programs in electric and magnetic rings, a variety of analytical estimates of particle and spin dynamics in the rings were developed and compared to the numerical results of tracking simulations. Initial discrepancies in the comparisons indicated the need for improvement of several of the analytical estimates. As an example, we found that the fourth-order Runge-Kutta/Predictor-Corrector method was slow but accurate, and that it passed all the benchmarks it was tested against, often to the sub-part per billion level. Thus, high precision analytical estimates and tracking programs based on fourth-order Runge-Kutta/Predictor-Corrector integration can be used to benchmark faster tracking programs for accuracy.
