| Outline of Final Research Achievements |
Characteristics of an ordered beam, which can be formed by applying strong laser cooling to ion beams circulating in a storage ring, were investigated using molecular dynamics simulations. Various dynamic behaviors were found such as the phase-space distribution and systematic oscillation of constituent ions in the ordered configuration, and their dependences on ring and beam conditions.
Moreover, the possibility of a simple profile measurement method using radiochromic films was considered toward measuring the cross-sectional structure of the ordered beam. It was found, through a microbeam irradiation experiment, that the radiochromic film has sufficiently a high spatial resolution of a few microns. The present result indicates that it is, in principle, possible to measure the cross-sectional structure of an ordered beam, which typically has a diameter of several hundred microns with inter-particle spacing of several ten microns.
