Study on beam crystallization by three-dimensional laser cooling in a dispersion-free storage ring and extraction of crystalline beams

为了实现极高质量的带电粒子束--“结晶束”，利用分子动力学模拟技术，探索了在无色散储存环中利用三维激光冷却形成结晶束的方法。由于库仑相互作用，这可能是一个障碍，束冷却的束加热，已被评估在很宽的温度范围内澄清的条件下的存储环和束结晶。还发现了从环中提取的晶体束稳定传输的物理条件。

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.
