 note = {"Neoclassical transport is studied for LHD configurations in which the magnetic axis has been shifted radially by determining the mono-energetic transport coefficient and the effective helical ripple.  With respect to the transport in the long mean free path collisionality region- the so called 1/nu transport -, the optimum configuration is found when the magnetic axis has a major radius of 3.53m, which is 0.22m inward shifted from the ""standard"" configuration of LHD.  In the optimized case, the effective helical ripple is very small, remaining below 2% inside 4/5 of the plasma radius.  This indicates that a strong inward shift of the magnetic axis in the LHD can diminish the neoclassical transport to a level typical of so-called ""advanced stellarators""."},
