摘　　要：为了使分束并行管道得到足够束流流强,首先对光阑分束孔径处束流流强进行理论计算,得出光阑孔径参数与束流流强之间函数关系式;在此基础上对理论计算进行了模拟验证,并考察了不同分束孔径下束流发射度的变化;最后对整条束流线结构布局进行分析计算,得出各光学元件参数。计算结果准确可信,能够满足核物理实验终端用户对束流品质要求.In order to get enough beam current for each parallel beam line, the beam intensi- ty distribution along aperture on the diaphragm is calculated to deduce a function which is verified by computer program for simulating charged particle beam transport systems, based on this function relationship between emittance of beam and the different aperture parameters on diaphragm is analyzed. At the end,a conceptual design of parallel beam line is given and the parameters of the optical elements are calculated. The results are accurate and credible, quality of beam can reach the requirements of user for nuclear physics experiments.
