- Abstract
- The Alfven Wave launching antennae in TCA have been changed. The wide stainless steel plates previously used have been replaced by a simple bar-antenna structure which has nonetheless maintained a pure n-spectrum. The antennae have also been coated with titanium nitride. The authors present results on the coupling properties of the new antennae and their effects on the plasma. Preliminary indications are that there is a considerable reduction in the metallic impurity concentration following this change.
