Abstract
In this paper, we consider the possibility of effective acceleration of ions driven by the radiation pressure force of an extremely intense pulse of a circularly polarized laser radiation. Using full-size 3D particle-in-cell imulation, target parameters such as thickness, density, and a degree of laser radiation focusing have been determined. These parameters are optimal from the point of view of the efficiency of conversion of radiation energy into ion energy, maximum energy and ion charge. It is shown that, with the laser radiation parameters expected at the XCELS facility, it is possible to obtain an ion beam with an energy of up to 1.7 GeV/nucleon with conversion efficiency reaching 40% and charge of ions of more than 50 nC , and an energy exceeding 500 MeV/nucleon.
