CYCIAE-100计划配套有7条束流线,将质子束流输运到不同的实验、生产终端以供不同的用户使用。目前各条束流线的布局设计、光学匹配均已完成。本文以ISOL系统质子管道为例进行了多粒子输运的模拟计算,以研究粒子在管道中的行为,研究管道中各包络较大的位置粒子的分布情况,进一步研究粒子在管道中的损失情况。图1示出了ISOL系统质子管道上各元器件的排布情况,图2示出了该束流线的光学匹配情况, The CYCIAE-100 program is equipped with seven beam lines that transport proton beams to different experiments and produce terminals for different users. At present, the layout of the beam line design, optical matching have been completed. In this paper, ISOL system proton pipe as an example for multi-particle transport simulation to study particle behavior in the pipeline, the pipeline in the envelope of the larger distribution of particles, to further study the particles in the pipeline loss Happening. Figure 1 shows the arrangement of the components on the proton pipe of the ISOL system, Figure 2 shows the optical matching of the beam line,
