In order to realize an extremely high-quality charged-particlebeam, "crystalline beam", a formation method of crystalline beams by means of three-dimensional laser cooling in a dispersion-free storage ring has been explored using the molecular dynamics simulation technique. The beam heating due to Coulomb interactions, which can be an obstacle to beam cooling, has been evaluated over a wide temperature range to clarify the conditions of a storage ring and beams for beam crystallization. A physical condition has been also found for stable transportation of crystalline beams extracted from a ring.

为了实现极高质量的带电粒子束--“晶态束”，利用分子动力学模拟技术，探索了在无色散存储环中利用三维激光冷却形成晶态束的方法。库仑相互作用引起的束流加热是束流冷却的障碍，已在较宽的温度范围内进行了评估，以明确用于束流结晶的储存环和束流的条件。还发现了稳定传输从环中提取的晶态光束的物理条件。
