Target Polarization Effect on Energy Loss of Ions near the Bohr Velocity

极化效应对Bohr速度能区O^(5+)离子在低密度氢等离子体中的能损影响

Energy loss of ions near the Bohr velocity in matter is one of the important topics in intense heavy ions beam driven high energy density physics and inertial confinement fusion.With the increase of ionization degree,plasma electrons will lead to changes in the process of ion energy deposition.Based on the ions-plasmas interaction device at 320 keV experimental platform,we present the experimental energy loss results of 1.07 MeV O^(5+)ions penetrating through a neutral hydrogen target and a low-density partially ionized hydrogen plasma target(radio frequency plasma).
