本文介绍了模拟碎片分离器工作的LISE程序，该分离器用于通过碎裂产生放射性束。讨论了产生这种放射性束所涉及的物理现象的各个方面。它们包括碎裂截面，材料中的能量损失，离子电荷态分布，以及离子光学计算和接受效应。该程序非常用户友好，不仅用于预测强度和纯度，以规划未来的实验，而且还用于实验期间的光束调谐，其结果可以快速与在线数据进行比较。此外，几个通用的工具，如物理参数计算器，核属性数据库，相对论两体运动学计算，使它有用的，甚至与稳定的光束实验。在对碎片分离器进行一般性描述之后，介绍了计算的基本原理，然后对程序及其功能进行了实际描述。最后，计算的几个例子进行了比较，在线数据，定性和定量。
This paper describes the program LISE which simulates the operation of fragment separators used to produce radioactive beams via fragmentation. Various aspects of the physical phenomena involved in the production of such radioactive beams are discussed. They include fragmentation cross-sections, energy losses in materials, ionic charge-state distributions, as well as ion optics calculations and acceptance effects. This program is highly user-friendly, and is designed not only to forecast intensities and purities for planning future experiments, but also for beam tuning during experiments where its results can be quickly compared to on-line data. In addition, several general-purpose tools such as a physical parameters calculator, a database of nuclear properties, and relativistic two-body kinematics calculations make it useful even for experiments with stable beams. After a general description of fragment separators, the principles underlying the calculations are presented, followed by a practical description of the program and its features. Finally, a few examples of calculations are compared to on-line data, both qualitatively and quantitatively.
