Enhanced proton acceleration via the leaky light-sail regime by laser interaction with nanofoils in strongly magnetized plasmas

摘要

An enhancing proton acceleration scheme is proposed by applying an external axial magnetic field in the leaky light-sail regime when a right-hand circularly polarized laser interacts with a multispecies nanofoil. In this scheme, the external axial magnetic field B-0 can not only enhance the intensity of the accelerating electric field but also adjust the spatial distribution of the accelerating electric field. It is shown by 2D3V particle-in-cell simulations that a monoenergetic proton beam could be produced in the case of
