| Research Abstract |
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.
