    Keywords : laser driven ion acceleration * nanostructured foils * proton beams
    Subject RIV: BL - Plasma and Gas Discharge Physics

    The enhancement of laser-driven proton acceleration mechanism in TNSA regime has been demonstrated through the use of advanced nanostructured thin foils. The presence of a monolayer of polystyrene nanospheres on the target frontside has drastically enhanced the absorption of the incident laser beam, leading to a consequent increase in the maximum proton beam energy and total laser conversion efficiency. The experimental measurements have been carried out at the 100 TW and 1 PW laser systems available at the APRI-GIST facility. Experimental results and comparison with particlein-cell numerical simulations are presented and discussed.
