Abstract
The first experimental campaign of the TJ-II stellarator has been conducted using electron cyclotron resonance heating (f = 53.2 GHz, P-ECRH approxima te to 250 kW) with a pulse length of Delta t approximate to (80-200) ms. Th e flexibility of the device has been used to study five different configura tions varying plasma volume and rotational transform. In this paper, the ma in results of this campaign are presented and, in particular, the influence of plasma-wall interaction phenomena on TJ-II confinement is briefly discu ssed.
