ABSTRACT

Field-reversed Configuration (FRC) sustainment from high-power neutral beam injection has been recently explored in the Tri Alpha Energy C-2U device. In this upgraded experiment, 10 MW hydrogen neutrals (15 keV) are injected for up to 10 ms into FRC target plasmas with densities of a few 10¹⁹ m^-3, and with temperatures of up to 1 keV. Plasma lifetimes > 10 ms have been obtained in the last few months, limited by the neutral beam pulse length. The C2-U device, the experimental results, and future directions will be presented in the talk.
