内容記述 | "Three-dimensional MHD equilibria including the bootstrap current self-consistently are studied for the Large Helical Device(LHD). Magnitude of the bootstrap current is sensitive to the magnetic axis position or Shafranov shift in LHD, which is proportional to the plasma pressure and inversely proportional to the rotational transform. Since the bootstrap current enhances the rotational transform and reduces Shafranov shift, the self-consistent MHD equilibrium is crucial to estimate the bootstrap current. Total bootstrap current easily exceeds 100kA for LHD plasmas with <beta> is greatter than or equal to l% under the assumption that both electrons and ions belong to the rare-collisional 1/nu regime in the whole plasma region, where <beta> is a volume averaged beta value. Effects of the vertical field, the quadrupole field and the pressure profile on the bootstrap current are also investigated." | |||||
