Riassunto:  The experimental feasibility of the laser-driven ion acceleration concept with multi-layered, foam-based targets has been investigated. Targets with the required features have been produced and characterized, exploiting the potential of the pulsed laser deposition technique. In the intensity range 1016–1017 W cm−2, they allow us to obtain maximum proton energies 2–3 times higher compared to bare solid targets, able to reach and surpass the MeV range with both low and ultrahigh contrast pulses. The results of two-dimensional particle-in-cell simulations, supporting the interpretation of the experimental results, and directions to exploit the concept also at ultrahigh intensities, are presented.

Ulteriori informazioni:  The research leading to these results has received funding from LASERLAB-EUROPE (grant agreements no 228334 and 284464, EC\'s Seventh Framework Programme), proposal no SLIC001689. We also acknowledge the support of the Italian Ministry for Education, Universities and Research (FIRB Futuro in Ricerca, SULDIS Project) and, for the simulations, PRACE for awarding us access to resource FERMI based in Italy at CINECA, via the project LSAIL. Some PIC simulations were performed using the computing resources granted by the Research Center Julich under the project HRO01.
