Abstract
The localization of unstable drift waves on the magnetic surface of a helically symmetric stellarator model is discussed using the balloonin g mode formalism. The spectrum is calculated on each node of a grid on a magnetic surface. The most unstable modes in a cold ion electrostat ic model are found to be localized on a band in the favourable curvatu re region.
