Design of plasma shutters for improved heavy ion acceleration by ultra-intense laser pulses

open access: yesNew Journal of Physics, 2022
In this work, we investigate the application of the plasma shutters for heavy ion acceleration driven by a high-intensity laser pulse. We use particle-in-cell and hydrodynamic simulations.
