Abstract

TEXTOR is a medium size tokamak with circular cross-section equipped with the ALT-II toroidal pumped limiter. It is dedicated to plasma wall interaction studies aiming towards a better understanding of the scrape-off layer and the plasma at the limiter edge. At a toroidal field of 2.25 T and with ALT at 0.46 m as the leading limiter, a density scan and a current scan were carried out using about 45 discharges in D shortly after boronisation of the TEXTOR walls. The first part of the paper concentrates on the ohmic phase of the discharges, while the second focusses on the ICRH phase of the discharge.
