Abstract

The energy relaxation processes of the surface produced H-ions due to the Coulomb collision and the charge exchange collision is verified by using 3D3V-PIC (three dimensions in real space and three dimensions in velocity space particle in cell) simulation. Under the present simulation condition (ne = 1.0 × 1018 m-3, TH+ = 0.25 eV, TH-= 1.5 eV (the initial temperature of the surface produced H-ion), nH/nH2 =0.5, nH = 9.4 ×1018 m-3, TH = 0.1 eV ), it is indicated the Coulomb collision is dominant for the energy relaxation processes. Moreover, it is indicated from the emittance diagrams that the H-ion beam optics is improved by the energy relaxation processes.
