Title: Improved Final Focus Shielding Designs for Modern Heavy-Ion Fusion Power Plant Designs

Conference ·
OSTI ID:793557

Recent work in heavy-ion fusion accelerators and final focusing systems shows a trend towards less current per beam, and thus, a significantly greater number of beams. Final focusing magnets are susceptible to nuclear heating, radiation damage, and neutron activation. The trend towards more beams, however, means that there can be less shielding for each magnet. Excessive levels of nuclear heating may lead to magnet quench or an intolerable recirculating power for magnet cooling. High levels of radiation damage may result in short magnet lifetimes and low reliability. Finally, neutron activation of the magnet components may lead to difficulties in maintenance, recycling, and waste disposal. The present work expands upon previous, three-dimensional magnet shielding calculations for a modified version of the HYLIFE-II IFE power plant design. We present key magnet results as a function of the number of beams.
