The process of radiation pressure ion acceleration is investigated with the aim of suppressing
the transverse Rayleigh-Taylor like interchange instabilities (RTI) in laser-foil interaction.
This is achieved by imposing surface and density modulations on the target surface. First,
calculations of the RTI growth rate are carried out in order to understand the behavior of
the instabilities. Then, PIC (particle-in-cell) simulations of radiation pressure acceleration
with dierent target modulation parameters are carried out. At the end, we analyze our
simulation results and seek for optimal modulation parameters for a stabilized acceleration
process of ions. It turned out that density modulated targets have more promising results
than surface modulated targets and we get new findings in radiation pressure of ions which
will probably lead to a new research direction.
