Investigation of 110 keV/u heavy ion beams interaction with hydrogen plasma.

The goal of this work is the experimental measurement and numerical simulation of the low energy ion beam interaction with hydrogen plasma. The detailed knowledge on the interaction between fast heavy ions and hot plasmas is not only a key issue in ion-driven inertial confinement fusion programs, but also an interesting subject related to atomic physics. Although, there are several theories on the energy loss of heavy ions in plasmas [1-3], there are still not enough experimental data to confirm these theoretical formulas. The stopping of projectile ions in hydrogen plasma targets has been recently measured experimentally mainly in projectile energy range about 1 MeV/u. However, few investigations of the stopping power of non-hydrogenic plasma target were conducted so far. Furthermore, the data base is not yet systematically compiled, especially for projectile energies below 0.5 MeV/u. With these points, new experimental data will give additional information for understanding interaction processes of low energy heavy ions in plasma. Background and justification For lower kinetic energies, the stopping power of plasma is expected to be even highe
