Accelerator-driven subcritical fission in a molten salt core (ADSMS) can use depleted uranium or thorium as fuel and produce 1 GWe power while destroying the transuranics produced. ADSMS requires multiple proton beams of 800 MeV energy and 10 mA CW current. A strong-focusing cyclotron (SFC) is being developed that uses sector dipoles each configured as a flux-coupled stack, creating independent cyclotrons that can be integrated within a common footprint. This presentation will introduce a 4-stack SFC that can provide the beam power needed in an ADSMS core to destroy transuranics at the rate and proportion made in a commercial GWe power reactor while also producing 300 MWe of power, equivalent to a x5 energy amplifier.

Space charge effects, beam losses, wake fields, and orbital control are significant collective effects that affect beam dynamics. The strong-focusing cyclotron incorporates helical orbits with a strong-focusing lattice and high-gradient cavities. It makes it possible to fully separate orbits and suppress interaction between bunches on neighboring orbits. We simulate nonlinear synchrobetratron coupling explore methods to use the tools of the strong-focusing cyclotron to suppress beam blowup mechanisms.

An accelerator based neutron damage facility (AND) is proposed to generate a high-dose fast neutron flux for testing of advanced reactor materials. The facility will be implemented in two stages. In AND-1, the 350 MHz LEDA RFQ will be re-commissioned to deliver 100 mA CW proton beam at 6.5 MeV. The beam will be targeted on a sheet-flow Li target to produce fast neurons. Samples located at a target station behind the sheet flow will receive up to 10 dpa/year of neutron damage with a mean neutron energy of 1.75 MeV. In AND-2, the LEDA beam will be modulated and passed through a spectrometer to produce three 117 MHz bunch trains, and two of them will be injected to two 100 MeV strong-focusing cyclotrons (SFC). The beams extracted from the two cyclotrons will be targeted in opposite directions onto sheet-flow Pb targets. Samples located in the space between the two targets will receive ~140 dpa/year of fast neutron damage with mean neutron energy ~10 MeV. AND-1 and AND-2 will provide the fast neutron flux needed for life-cycle damage studies for advance reactor technologies and for first-wall simulations for fusion systems.
