Abstract

Bootstrap current calculations with the neoclassical SPBSC and VENUS+δf codes have been performed on experimental Large Helical Device (LHD, NIFS, Japan) configurations with different magnetic axis positions and simplified plasma density and temperature profiles. In this paper, we use experimentally obtained electron density and temperature profiles for the LHD discharges #61863 and #82582 to compute the corresponding magnetohydrodynamic equilibrium states and collisional frequency. An improved collisional operator has been implemented into the VENUS+δf code. The comparison between the measured LHD bootstrap current and that expected from neoclassical simulations is discussed.
