Abstract. Since March 2001 TEXTOR undergoes a rebuild to install the
Dynamic Ergodic Divertor (DED). TEXTOR will come into operation in August.
During the campaigns before the shutdown new results were obtained on:
-Internal electron transport barriers found in NCS- but also in normal
L-mode plasmas related to specific q-values; -Further improvements of the
RI-mode with central ECRH and extension towards trans-Greenwald densities;
-Magnetic islands giving enhancement/reduction of turbulent fluctuations and
transport around X-/O-points respectively; -Fast ion dynamics during
sawtooth crashes measured with Collective Thomson Scattering; -Impurity
transport analysis gave diffusion coefficients and inward convection values
to be compared with gyro-Bohm/ITG-model predictions; -Erosion/deposition of
carbon, fuel retention and hydrogen recycling near limiters.
