Abstract
Recent experimental works with ion traps are surveyed.Ion traps can confine ions of very low-energy in a small space, and they are useful tools for the precise spectroscopy of ions.Basic ideas on trapping mechanism of several types of the traps and detection methods of trapped ions are summarized.Major topics are ultrahigh-resolution spectroscopy of ions using laser cooling methods and physics on one-component plasmas such as localization, phase transition and crystallization of ion cloud.Applications to elementary particle physics , nuclear physics and atomic physics on multiply charged ions are also presented.
