| Summary | Ion acceleration through laser-plasma is one of the promising technologies for realizing laboratory high energy physics, astrophysics, and table-top cancer therapy. Under irradiation of an intense focused laser onto a large area suspended graphene target to result in ionization of the target into plasma state, protons and heavier ions can be accelerated to high energies through the strong electric field from the electron sheath. Although theoretical prediction indicated higher ion energy can be produced using a thinner target (~ 10 nm), fabrication of thinner suspended film is so far unsuccessful. Here we devise a suspended graphene based target for the above purpose and demonstrated extremely high energy proton, carbon ions, and gold ions acceleration feasibility. |
