[en] The electron temperature and density in the ASDEX main chamber boundary plasma are measured using a movable double probe. From the measured density and temperature profiles we can deduce characteristic decay lengths illustrating the transport in this particular region out of the separatrix. The effects of two types of heating are investigated, during the neutral beam injection the boundary plasma seems to respond to the high and low β regimes found in ASDEX. The lower hybrid heating affects the boundary plasma by increasing the electron temperature and modifying the density profile. (orig.)
