沿Alvarez DTL截面的横向发射度增长是GSI UNILAC高电流光束质量保存的主要问题。为了确定减少这种增长的措施，适当的工具来模拟光束动力学是必不可少的。本文对三种光束动力学仿真代码，即DYNAMION， PARMILA和PARTRAN进行基准测试，以对抗不同机器设置下光束发射度增长的系统测量。实验设置，数据缩减，模拟的准备和模拟的评估将被描述。结果表明，该规范能较好地再现最终水平和垂直均方根发射度的平均值。
Transverse emittance growth along the Alvarez DTL section is a major concern with respect to the preservation of beam quality of high current beams at the GSI UNILAC. In order to define measures to reduce this growth, appropriate tools to simulate the beam dynamics are indispensable. This paper is on benchmarking of three beam dynamics simulation codes, i.e. DYNAMION, PARMILA and PARTRAN against systematic measurements of beam emittance growth for different machine settings. Experimental set-ups, data reduction, the preparation of the simulations, and the evaluation of the simulations will be described. It was found that the mean value of final horizontal and vertical rms-emittance can be reproduced well by the codes.
