This effect was studied for the deuteron fusion reactions taking place in metallic environments as a model for dense astrophysical plasmas. Experimentally determined screening energies corresponding to the reduction of the Coulomb barrier height are much larger than the theoretical predictions. One possible explanation is the excitation of a hypothetical threshold resonance in the 4He nucleus. As the energy dependence of the resonant reaction cross section differs to that of the electron screening effect, one can distinguish between both processes expanding measurements down to the deuteron energies of 1keV. A novel ion accelerator was implemented at the University of Szczecin. Ions are produced by a Dresden ECRIS-2.45M as a high-current, low-Z ion source. The following beam line is designed to work on HV potential for decelerating ions below a kinetic energy of 1keV and combined with a ultra-high vacuum target chamber to reduce target impurities. The ion irradiation facility as well as first experimental results are described and discussed.
