AbstractAbstract
[en] Transport code calculations were made for experiments with combined operation of Lower Hybrid current drive and heating and neutral beam injection heating on ASDEX. Peaking or flattening of the electron temperature profile is mainly explained with MHD-induced electron heat transport. It is governed by current profile changes due to Lower Hybrid and neutral beam current drive and contributions from the bootstrap current. Ion heat transport can not be described with one single model for all heating scenarios. The ion heat conductivity is reduced during Lower Hybrid heated phases with respect to Ohmic and neutral beam heating and drops below the neoclassical value. (orig.). 6 figs
