Paper Abstract

The stability of accleration of ions in the RPDA regime against transversal shift of the cluster target relative to gaussian and supergaussian laser pulses is considered. It is shown that the maximum energy of ions decreases while the shift increases, as the target escapes the acceleration domain. The effect of self-focusing for the supergaussian pulse profile is found and interpreted. An analytical approach based on the relativistic mirror model is developed. We also conduct PIC simulations that prove our theoretical estimations. The results obtained can be applied to the optimization of ion acceleration by the laser radiation pressure with mass-limited targets.
