Modeling the interaction of an ultra-high intensity laser pulse with nano-layered flat-top cone targets for ion acceleration

We propose new nanotargets as nano-layered flat-top cone targets to be used for future laser-ion acceleration experiments at ELI-NP. We study their behaviour at the interaction with an ultra-high intensity laser pulse by performing Particle-In-Cell simulations. We analyze spatio-temporal the electro...

Description
Summary:We propose new nanotargets as nano-layered flat-top cone targets to be used for future laser-ion acceleration experiments at ELI-NP. We study their behaviour at the interaction with an ultra-high intensity laser pulse by performing Particle-In-Cell simulations. We analyze spatio-temporal the electromagnetic field based on the finite-difference time-domain method for a complementary description. We find the optimum diameter of the nanospheres and the proper nano-flat-top foil thickness for which one can obtain monoenergetic beams of very energetic ions with low angular divergence.
