Selective Deuteron Acceleration using Target Normal Sheath Acceleration
… accelerated to multi-MeV energies after irradiation with an ultra-intense laser. The versatility of an ion beam for the generation of neutrons can be improved by tailoring which ions are accelerated. Nominally, the dominant species accelerated is the lightest present on a target surface typically …
