Abstract

A heavy ion beam probe (HIBP) using a 3 MV tandem accelerator was installed in Large Helical Device (LHD). It is designed to measure the electrostatic potential in the core region directly. It is calibrated and can be used to measure the electrostatic potential profiles in LHD plasmas. The radial electric field (E_r) obtained from the potential profiles measured using the HIBP agrees with that measured by charge exchange spectroscopy (CXS). E_r predicted by the neoclassical theory is also compared to that measured using the HIBP, and is in good agreement with the experimental results in the core region.
