- Abstract
- The development of novel target concepts is crucial to make laser-driven acceleration of ion beams suitable for applications. We tested double-layer targets formed of an ultralow density nanostructured carbon layer (∼7 mg=cm3, 8-12 μm-thick) deposited on a μm-thick solid Al foil. A systematic increase in the total number of the accelerated ions (protons and C6+) as well as enhancement of both their maximum and average energies was observed with respect to bare solid foil targets. Maximum proton energies up to 30 MeV were recorded. Dedicated three-dimensional particle-in-cell simulations were in remarkable agreement with the experimental results, giving clear indication of the role played by the target nanostructures in the interaction process. © 2016, American Physical Society.
