Abstract

With an ultra-soft X-ray pinhole camera, installed on the Wendelstein VII-A stellarator, changes of the plasma topology have been measured for various plasma conditions over several years. A recently finished tomography computer code, specifically written for pinhole cameras, has yielded detailed information about the time evolution and structure of tearing modes during internal and external disruptions. The features of the m=1 tearing mode during an internal sawtooth disruption in a current- carrying stellarator plasma during neutral beam injection are presented.
