“…The possibility to use heavy ion beams was less analyzed and the conclusions of authors are contradictory [2]- [3]. Our results presented in [4] show that one can get a higher efficiency by accelerating heavier ions. In the present work we analyse in more detail the use of light ion beams at energies below 1 AGeV.…”

Abstract. A comparative study of the energy efficiency of proton beams with an energy from 0.5 GeV to 4 GeV and light ion beams ( 7 Li, 9 Be, 11 B, and 12 C) with energies from 0.25 AGeV to 1 AGeV in natural and enriched quasi-infinite U target is presented. The numerical results on the particle transport and interaction are obtained using the code Geant4. The following target optimization issues are addressed: the beam window dimensions, and the possibility to use a core from low Z materials. The best solution for ADS from the point of view of the energy gain and miniaturization is obtained for 7 Li or 9 Be beam with an energy of 0.3-0.4 AGeV and a target with Be core.

“…The design of an ADS must retain these advantages and maximize the energy efficiency. In the previous works the authors demonstrated that light ion beams have a superior energy efficiency for ADS as compared to protons [1,2]. These conclusions were obtained in quasi-infinite natural and enriched uranium targets.…”

“…Proton with energy 1.5 GeV (energy at which protons accelerated in a linac have the maximum energetic efficiency [1]) was used as reference particle. A value of 0.18 for the total accelerator efficiency for the reference particle was considered.…”

The new concept of light nuclear beams instead of proton beams for ADS is substantiated. The influence of the target structure on the energy efficiency of 0.5-4 GeV proton beams and 0.25 – 0.5 AGeV light ion beams is studied. The target consists of rods with different composition (metal, oxide, carbide) and different levels of enrichment in order to implement the target with a criticality coefficient of 0.96 -0.97, which ensures safe operation. The cooling with different metals (lead, lead-bismuth eutectic - LBE, and sodium) is compared. The use of converters from very light materials (lithium, beryllium, carbon) and their influence on the neutron spectrum and energy released are analysed.
