Abstract:
An advanced Large Helical Device (LHD) type proton-boron reactor, in which the minority protons are heated by ICRF, is proposed. The ratio of the fusion power to the RF input power is evaluated. Numerical computation of particle orbits shows that the ICRF of LHD can accelerate protons in the p-^11B fusion relevant energy. Numerical results also show that the LHD magnetic configuration can confine the high energy ^4He well. An active peripheral potential control method and an active ^4He ash exhaust scheme are discussed.
