Abstract

A transport code has been developed which comprises lower hybrid (LH) wave propagation, absorption, plasma heating, current drive, MHD induced transport and anomalous electron heat conductivity. This code was applied to a set of ASDEX discharges covering a wide range of LH experiments. Suppression of sawteeth and m = 1 oscillations with subsequent strong peaking of the electron temperature profile, and the dependence of the confinement time on power and density, are described self-consistently in the simulation. In MHD stable LHCD plasmas with high central electron temperatures and peaked T(e)(r) profiles, the electron heat conductivity in the central plasma region approaches neoclassical values.
