摘要
We observe the proton signals produced by laser interaction with thin-foil targets of polyimide and of copper. We change the thickness of the polyimide target to 7.5 mu m, 12.5 mu m, and 50 mu m. High-energy protons with the maximum energy of similar to 2.3 MeV from 7.5 mu m thick polyimide are observed. This proton bean with the maximum energy of multi-MeV has various applications such as a proton shadowgraphy.
