Abstract
At the Thirteenth International Symposium on Heavy Ion Inertial Fusion (HIF Symposium), we presented magnet shielding calculations for 72-, 128, 200, and 288-beam versions of the HYLIFE-II power plant design.1,2 In all cases, we found the radiation-limited lifetimes of the last set of final focusing magnets to be unacceptably short.1 Since that time, we have completed follow-on calculations to improve the lifetime of the 72-beam case. Using a self-consistent final focusing model, we vary parameters such as the shielding thicknesses and compositions, focusing length, angle-of-attack to the target, and the geometric representation of the flibe pocket, chamber, and blanket. By combining many of these shielding features, we demonstrate a shielding design that would enable the last set of final focusing magnets to survive for the lifetime of the power plant.
