FRTP prototype power reactors with neutral-beam heating and pellet injection

The Field-Reversed Theta Pinch (FRTP) represents a promising confinement approach to fusion power. This has become more evident because of the favorable confinement scaling that has been predicted based on studies of Loss-Cone Scattering Transport (LCST). Therefore, a step toward the FRTP prototype power reactors is proposed. The potential advantaes of the FRTP reactors includes: 1) high /beta/and hence high power density, 2) compactness, 3) high density (10/sup 15/ -10/sup 16/ cm-/sup 3/ ) and readily hot (1-3keV) plasma formed by implosion, compatible with further (neutral-beam) heating, 4) simple linear geometry and hence easy modular production and maintenance, and 5) easily coupled direct energy conversion. Neutral-beam heating and pellet refueling are assumed in these reactors, serving simultaneously for heating, refueling and maintaining the field reversal and the plasma moment of inertia
