Efficient transverse laser cooling of a low-intensity heavy-ion beam has been recently accomplished experimentally by means of the resonant coupling method at the cooler storage ring S-LSR of Kyoto University. In parallel with the experimental effort, multi-dimensional laser cooling of the ion beam has been studied also numerically with the molecular dynamics (MD) simulation code in which the stochastic interaction between ions and laser photons is incorporated in order to search optimum laser-cooling conditions and verify the results of the experiment. The present MD result demonstrates that, in spite of the limited experimental conditions of the cooling laser such as low power, fixed frequency, and short cooling section, a three-dimensionally low-temperature beam of 40-keV $$^{24}$$Mg$$^+$$ can be obtained through resonant coupling at a low intensity of $$10^4$$ ions in the ring, which is consistent with the experimental result.
