Experiments on laser acceleration of macroparticles conducted at the PALS facility are reported. Superfast macroparticles were obtained by using the cavity pressure acceleration method. Two different acceleration schemes were investigated: the “forward” and “backward” acceleration. For both of them the hydrodynamic efficiency of the energy transfer to the accelerated macroparticle is much higher compared to conventional ablative experiments. The highest velocity achieved for a 20-microm polystyrene foil target approaches 10^8 cm/s. In addition, application of “covered-channel” targets results in evident increase of density of the accelerated plasma.
