      abstract     = {Conditions for efficient and stable ion radiation pressure
                      acceleration (RPA) from thin foils by circularly polarized
                      laser pulses at moderate intensities are theoretically and
                      numerically investigated. It is found that the unavoidable
                      decompression of the co-moving electron layer in Light-Sail
                      RPA leads to a change of the local electrostatic field from
                      a "bunching" to a "debunching" profile, ultimately resulting
                      in premature termination of ion acceleration. One way to
                      overcome this instability is the use of a multispecies foil
                      where the high-Z ions act as a sacrificial species to supply
                      excess co-moving electrons for preserving stable
                      acceleration of the lower-Z ion species. It is shown by 2D
                      particle-in-cell simulations that 100 MeV/u monoenergetic
                      C6+ ion beams are produced by irradiation of a Cu-C-mixed
                      foil with laser pulses at intensities 5 x 10(20) W/cm(2),
                      which can be easily achieved by current day lasers. (C) 2011
