The design of a 1,000 MWe light ion driven fusion power plant is given. Considerable progress has been made in analyzing the target performance and. its impact on the cavity design. Recent declassification actions in the U.S. have resulted in more detailed calculations that reveal a somewhat lower gain (⋍70) compared to those gains previously assumed (80-100). Methods to recover that more conservative gain from other parts of the reactor design include more efficient beam transport and higher conversion efficiencies to electricity.
