Observation of Energetic Ions from a Beam-Generated Plasma

Abstract
Experiments are described which show that pulsed high intensity electron beams can accelerate light ions to high energies. A set of time‐of‐flight measurements shows proton and deuteron energies of 5 MeV, helium ion energies of 9 MeV, and nitrogen ion energies of about 20 MeV, produced by an electron beam with a maximum electron energy of 1.6 MeV. These measurements are confirmed by Be9 (x, n) reactions for protons, deuterons, and helium ions. Further confirmation is made with an absorber measurement for the protons.
