Abstract

Advanced nanostructured thin foils have been used in order to enhance the laser-driven proton acceleration mechanism in TNSA regime. In particular, the presence of a monolayer of polystyrene nanospheres on the target front-side has drastically enhanced the absorption of the incident laser beam, leading to a consequent increase in the maximum proton beam energy and total charge. The experimental measurements have been carried out at the 100 TW laser systems available at the APRI-GIST facility. This is the first experimental demonstration of such advanced target geometry which was previously presented through particle-in-cell numerical simulation. Experimental results and comparison with theory are discussed.
