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 (n_e = 1.0 × 10¹⁸ m^-3, T_H+ = 0.25 eV, T_H-= 1.5 eV (the initial temperature of the surface produced H-ion), n_H/n_H2 =0.5, nH = 9.4 ×10¹⁸ m^-3, T_H = 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.
