Description
The planned Da Vinci Field-Reversed Configuration fusion reactor will require several Neutral Beam Injectors each delivering 1 MeV 5 MW continuous neutral beams. A considered design option includes a spatially separated H- ion source and an electrostatic accelerator as was previously proposed [1].
Here the status of the numerical analysis work supporting the ongoing design efforts is presented. The simulations include modeling and optimization of the H- ion source extraction system and the downstream transport, acceleration and neutralization systems with the goal of delivering the required beam at the reactor vessel beam injection port.
Special attention will be given to estimation of the required level of space-charge compensation together with the allowable stripping losses.
