Progress in particle accelerator technology enables the use of the proton accelerator as an effective tool for energy production and nuclear waste destruction. The Energy Ampliéer (EA) proposed by Carlo Rubbia and his group ì a subcritical fast neutron system driven by a proton accelerator ì may prove particularly effective in destroying, through éssion, transuranic elements produced by current nuclear reactors. Combined with the Adiabatic Resonance Crossing (ARC) concept recently tested in the TARC experiment at CERN, the EA provides an efécient and cost-effective method for transforming long-lived éssion fragments. A number of other application areas (production of radioactive isotopes for medicine and industry; fundamental neutron research, etc.) may beneét from the extension of the ARC concept as well.
